TIA TR 42.1 (Commercial Building Cabling) and TIA TR 42.7 (Copper Cabling Systems)Mesa, AZ, February 3–5, 2009 The TIA TR 42.1 (Commercial Building Cabling) Subcommittee has developed the updates to the well-known TIA 568 series of standards—568-C.0 and 568-C.1—for generic information and for commercial building telecommunications cabling (minimal require-ments for telecom cabling systems within commercial buildings), which have been approved and soon to be for sale (now buy 568-B.1). The TIA TR 42.7 (Copper Cabling Systems) Subcommittee is responsible for the also well-known TIA 568 B.2 Standard for the user and manufacturer to follow for copper hardware specs and performance. During this first group of meetings in 2009, discussion covered the status of TIA 568-C.2 for Balanced Twisted-Pair Cabling Components, which was still likely to be published after October. They also covered the Data Center standard (TIA-942), the Building Automation Standard (TIA-862), a new standard for Health Care Facilities, the Outside Plant standard (TIA-758), the MICE Tutorial (TSB 185), the new field tester standard (TIA 1152), the TSB for current capacity over UTP (TSB 184), and the revision of TSB 155 for 10 gigabit Ethernet over Category 6 cabling.

1. TIA 568-C.0 (Telecom Networks) Status➣ ACTION: When corrected, TIA 568-C.0 “Cus-tomer-Owned Telecommunications Networks” will be available from IHS at www.ihs.com.
2. TIA 568-C.1 (Commercial Building Cabling) Status➣ ACTION: After final editorial changes are made, TIA 568-C.1 “Commercial Building Telecommuni-cations Cabling Standard” will be available from IHS.
What You Need to Know
To purchase, visit the IHS website at http://store.ihs.com and enter the standard’s identifier (TIA 568-C.0 or C.1) or go to www.tiaonline.org and search for a standard and place your order through TIA with IHS.
3. TIA 568-C.2 (Copper Cabling Components) Ballot Comment ReviewAny contributions meant for this standard will be re-viewed at the TR 42.7 Interim Meeting, May 2009. Subcommittee members will be requested to confirm that the proposed changes are “editorial” and correc-tions as appropriate would be made to the current draft, in preparation for publication.
➣ ACTION: Publication of TIA 568-C.2 “Copper Cabling Components” is expected after October 2009.
What You Need to Know
Follow the progress of TIA 568-C.2 to see if it’s available for sale through IHS before the end of 2009.
4. TIA 942 (Additional Media and Guidelines for Data Centers) Ballot Comment ReviewIssue: Since this document also describes tempera-ture and humidity requirements, media, etc., make the title more broad.Resolution: Would retitle TIA 942, Addendum 2 as “Additional Guidelines for Data Centers.”
Issue: The Table titled “Revised temperature and hu-midity requirements for telecommunication spaces” is being revised for the Pathways and Spaces updated standard. What should you show here if it’s really not completed yet?Resolution: They would retain the table’s informa-tion that only pertains to the data center for now. (See illustration on page four for the data center information.)

Maximum rate of temperature change: 5°C (9°F) per hour
5. TIA 862 (Building Automation Systems) Ballot Comment ReviewA “mock” ballot had been issued and reviewed and comments resolved. Many changes were made to be consistent with terminology as used in 568-C.0 and C.1 and to properly reference current standards
Issue: This is a generic document, make it look that way.Resolution: Since its title now is “Building Auto-mation Systems Cabling Standard for Commercial Buildings,” remove “for Commercial Buildings.”
Issue: Does “Coverage Area” remain in this docu-ment as a legitimate space?Resolution: Yes, because it is specific to the BAS cabling infrastructure.
Issue: Don’t confuse a work area with a work station. One is a cubicle area and the other is a computer.Resolution: Show by definition that the work area is a building space where the occupants interact with telecommunications terminal equipment. This has nothing to do with a “work station.”
Issue: Make sure people understand we are talking about centralized cabling for BAS and not a central-ized BAS system.Resolution: Rename Section 3.3 Centralized BAS Cabling.
Issue: Include the telecommunications enclosure un-der the section for backbone cabling.Resolution: Section 4.1 (General) would add tele-communications enclosures (TE’s) to the list of in-terconnections (such as for the telecommunications room, the common telecommunications room, the equipment room, etc.).
Issue: When describing where a Zone Box can go, remember it can also be placed in the floor.Resolution: Change text to state that the Zone Box shall be located in a fully accessible, permanent loca-tion, such as a building column, a floor or a perma-nent wall, and should be provided with appropriate security.
Issue: There are more mounting options for a Zone Box than are mentioned in this draft.Resolution: They would rewrite Section 6.4.5 titled “Plywood Backboards” and call it “Mounting Meth-ods” and state that a variety of methods can be used including: metal perforated panel, plywood back-board or EIA-310-E compliant mounting. These may be located in the back or side of the interior portion of the box.
Issue: Regarding grounding and bonding of the zone box, remind the reader to comply with the require-ments in the TIA grounding and bonding standard ANSI-J-STD-607-A.

What You Need to Know
The new Figure 1 would be changed to reflect the change to showing TIA 758-A as a common standard as opposed to being under the premises standards. The illustration on page 6 shows you where 758-A has moved.
9. TSB 185 (Mice Tutorial) StatusThe task group was still waiting for international documents to review.
➣ ACTION: The next meeting should be able to prepare a Default, MICE TSB.
10. TSB 184 (Current Capacity) Status
A couple comments to be on the Default Ballot:
Issue: You need to strengthen this standard by in-cluding a reference and also indicate that Category 5e cabling is the minimum requirement.Resolution: Change text to say that remote power-ing should be implemented using Category 5e or better 4-pair balanced twisted-pair cabling as speci-fied in ANSI/TIA-568-C.2.
Issue: In the Annex A list of “Considerations for current capacity of category types and installation conditions—Temperature Rise Considerations,” be specific about whether “heat transfer” is a significant parameter.Resolution: Added the entry “Improved heat trans-fer coefficient between materials” to the list.
➣ ACTION: A 30-day Default ballot was agreed to for the technical changes made. Draft 4.0 would be created and posted to TIA’s ftp site.
11. TIA 1152 (Field Testers) StatusThe group reviewed all ballot comments and made appropriate technical changes. Other than some definition additions and reference corrections, here are some of the technical changes:
Issue: Combine the Introduction and Scope into a new Scope to be clearer.
Resolution: The grounding and bonding section would be rewritten to state that if the Zone Box includes metallic components, the grounding shall meet the requirements and practices of applicable authorities or codes. In addition, the telecommuni-cations grounding/bonding system shall conform to ANSI-J-STD-607-A requirements.
Issue: Since bundled cabling requirements are differ-ent than requirements for individual 4-pair cabling, tell people.Resolution: Refer to proposed TIA TSB-184 for cur-rent capacity of bundled cabling. Bundled cabling requirements are different than individual 4-pair cabling requirements.
➣ ACTION: The update to TIA-862 (BAS Cabling) would go out for its first internal 30-day ballot.
6. TIA 568-C.1, Addendum 1 (Temperature Limits) Status➣ ACTION: An Addendum would be created to TIA 568-C.1 for pathways and spaces specific to commercial buildings. No timeline information given yet.
What You Need to Know
No due date information for this new Addendum has been given out yet.
7. Energy EfficiencyIEEE 802.3 acknowledged TR 42’s support of “green initiatives” and replied that they were working on this issue by developing energy efficient PHY’s and applications that work over TIA specified cabling.
➣ ACTIONS: 1. A “green initiative” paragraph was recom-
mended for inclusion in the foreword of future TR-42 standards (see TR 42.3 section for text).
2. TIA would share any progress on the develop-ment of energy-efficient cabling specs with IEEE.
8. TIA 758-A (Outside Plant) StatusIt was discussed that this standard should now be-come common to all others. This would result in a change to the figures in TIA 568-C.0 and C.1 and hopefully, an editorial change would get in before both documents were published.
➣ ACTION: Figure 1 in TIA 568-C.0 and C.1 would be editorially changed to reflect the “com-mon” placement of TIA 758-A for Outside Plant.

Volume 01-09
Cabling Standards • Telecommunications Industries Association
Resolution: The Standard’s Scope would read: “This Standard includes requirements for field test instruments that are used to test balanced twisted-pair cabling as specified in the ANSI/TIA-568-C series of structured cabling standards. This Standard specifies the reporting and accuracy performance requirements of field testers for balanced twisted-pair cabling measurements. Level IIe, III, and IIIe field tester requirements are also specified in this Stan-dard. This Standard contains methods to compare the field instrument measurements against labora-tory equipment measurements specified in ANSI/TIA-568-C.2. Measurement accuracy based upon the assumptions for key performance parameters is addressed.”
Issue: Correct where the permanent link and chan-nel information actually resides.Resolution: This would be changed from TIA 568-C.0 to TIA 568-C.2.
Issue: Since there is no information about testing anything less than Category 5e cabling, explain.Resolution: Change the text to say that a Level IIe tester is suitable to test up to and including Category 5e cabling.
Issue: Do the same thing for Category 6 and 6A testing.Resolution: Change the text to say that a Level III tes-ter is suitable to test up to and including Category 6 cabling and that a Level IIIe tester is suitable to test up to and including Category 6A cabling.
Issue: Explain more clearly, the performance param-eters for Level IIe testers.Resolution: Say that “Level IIe field testers shall conform to the requirements in the Table for Mea-surement Requirements for Level IIe Testers for the baseline, permanent link, and channel test configura-tions. The channel accuracy performance parameters include the effects of the modular jack mating of the test instrument with the local end of the user patch cord. Methods to verify compliance of field tester re-quirements are specified in clause 4.5 (Procedures for testing field tester parameters).”
Issue: Explain more clearly, the performance param-eters for Level III testers.Resolution: Say that “Level III field testers shall conform to the requirements in the Table for Mea-surement Requirements for Level III Testers for the baseline, permanent link, and channel test configura-tions. The channel accuracy performance parameters include the effects of the modular jack mating of the test instrument with the local end of the user patch cord. Methods to verify compliance of field tester re-quirements are specified in clause 4.5 (Procedures for testing field tester parameters).”

Cabling Standards • Telecommunications Industries Association
TIA TR 42.2 Residential Cabling Mesa, AZ, February 5, 2009The TIA TR 42.2 committee that created the TIA 570-B standard for “Residential Telecommunications Ca-bling,” has recently approved a standard for “Additional Requirements for Broadband Coaxial Cabling” in the data center (570-B, Addendum 1) which is now avail-able. At this first meeting in 2009, they looked at when TIA 570-B should be updated and what new work should be undertaken.
Meeting Topics 1. TIA 570-B.1 (Coax Cabling) Status 2. TIA 570-B Status 3. New Projects 4. Next Plenary Meeting
1. TIA 570-B.1 (Coax Cabling) Status➣ ACTION: TIA 570-B.1, “Additional Require-ments for Coax Cabling,” was published 1/22/09.
This standard should now: 1. Encompass the coax cable that has been
“blessed” by cable and satellite people. 2. Be very relevant regarding the change to digital
service where users may have to run new cable. 3. Set a new kind of benchmark with coax for
high-speed digital applications.
What You Need to Know
To purchase TIA 570-B.1, visit www.tiaonline.org and search for a TIA 570-B and place your order for 570-B.1.
2. TIA 570-B Status➣ ACTION: TIA 570-B was reaffirmed by the sub-committee and any revision/update to TIA 570-B would be delayed until TIA 569-C was finished.
What You Need to Know
In the meantime, reaffirmation of TIA 570-B would go out to TIA members, following the appropriate policy. Members noted that this standard still needed to be strengthened and there was a suggestion to work closely with SCTE. If necessary, a press release could be sent out announcing the reworking of 570-B to elicit more input.
3. New ProjectsDistributed/Whole House Audio• This is where the audio can be distributed through-
out the house and zones can be separated out.
To liaison with CEA (Consumer Electronics Assoc.) re distributed audio.
Home Theater• CEDIA does training and CEA writes standards.• First, start a relationship with CEDIA.• Reference CEDIA’s standards if they write them.
Video Cabling• Need to work with someone involved in connect-
ing to services.• Broadband coax is for video applications.
SecurityNeed to work on IP video.
Home AutomationSince there are computers in the house, you can con-trol appliances, etc. The house becomes an “intel-ligent building.” Some systems are wired and some are wireless.
➣ ACTIONS: 1. Study Group created to look into home the-
ater, distributed audio and video cabling. 2. Establish formal liaison with CEDIA. 3. Study Group created to make recommenda-
tions for additional content for Home Theater and Distributed Audio.
Discussion• Create a “generic” coaxial cabling standard—like a
568-C.4 for broadband coax cabling.• Every hospital has coax and it can’t be ignored.• Remember that the cable used has to be “plenum
rated.”
➣ ACTION: This concept was introduced at the Plenary and it was agreed that the idea of creating a standard for “generic” coaxial cabling would be reviewed by the TR 42.7 (copper cabling compo-nents) group for later incorporation into 568-C.2. This would be discussed again at the October 2009 Plenary meeting.
What You Need to Know
If you are interested in the direction of this group’s stan-dards work, attend the next Plenary Meeting, August 3-7, 2009 (see www.tiaonline.org for location).

TIA TR 42.3 Pathways & Spaces Mesa, AZ, February 3, 2009The TIA TR 42.3 subcommittee created the standard, TIA 569 for Commercial Building Telecommunications Pathways and Spaces. At this first Plenary meeting of 2009, the group covered the final version of the Green Stewardship/Initiative umbrella statement TR 42 would be using with future standards, the CITG (Cabling Implementation Task Group out of ISO/IEC) liaison report, the acceptance of comments on TIA 569-B.1 for Temperature and Humidity, the final changes agreed to for TIA 1005, Addendum 1 (Industrial Pathways and Spaces), and how the update to TIA 569-C would be handled.
Report 3. Changes to TIA 569-B, Addendum 1 “Temperature
and Humidity Requirements for Telecommunica-tions Spaces”
4. Changes to TIA 1005, Addendum 1 “Industrial Path-ways and Spaces”
5. TIA 569-C (3rd revision) Update Plan 6. Next Plenary Meeting
1. “Green” InitiativeThe Stewardship/Initiative paragraph was finalized and put on the 2008 section of the TIA website.
The Study Group agreed on the following final draft:Telecommunications infrastructure affects raw ma-terial consumption. The infrastructure design and installation methods also influence product life and sustainability of electronic equipment life cycling. These aspects of telecommunications infrastructure impact our environment. Since building life cycles are typically planned for decades, technological electronic equipment upgrades are necessary. The telecommunications infrastructure design and in-stallation process magnifies the need for sustainable infrastructures with respect to building life, elec-tronic equipment life cycling and considerations of effects on environmental waste. Telecommunications designers are encouraged to research local building practices for a sustainable environment and conser-vation of fossil fuels as part of the design process.
➣ ACTION: This statement was incorporated into 569-C.
ISO/IEC and the CITG were planning the final CD (Committee Draft) to be ready for their March IEC meeting.
Discussion• The group wanted to adopt TIA’s Identifier mark-
ings from TIA-606-A.• Some annexes still needing to be finished:
- Infrastructure complexity classification- Pair-pin configuration and optical polarity- Data Centers - Industrial - Residential
• Some annexes up for review next meeting:- Multi-tenant premises- Office premises- Space allocation for functional elements
➣ ACTION: The CITG had agreed to adopt TIA’s 606-A identifiers.
3. Changes to TIA 569-B, Addendum 1 “Temperature and Humidity Requirements for Telecommunications Spaces”
The major changes resulting from the ballot com-ment review were:
Issue: Since this Addendum was for “revised” tem-perature and humidity requirements for telecommu-nications spaces, be correct.Resolution: See table on Page 13 that reflects all changes to ASHRAE requirements.
Issue: Make the method of measuring ambient tem-perature and humidity more practical.Resolution: Paragraph rewritten as: “Temperature and humidity should be measured at air intakes of operating (powered) equipment and, except in tele-communications enclosures, at a distance of 1.5m (5 ft) above the floor level every 3 to 9m (10 to 30 ft) along the center line of the aisles at the front of the cabinets or racks. In telecommunications en-closures the temperature and humidity should be measured as near as practical to the center of the enclosure.”
➣ ACTION: TIA 569-B.1 to go out for a Default Ballot, since technical changes were made.
Cabling Standards • Telecommunications Industries Association
What You Need to Know
This will go out to a Default ballot (30 days) and it could be finalized in August and for installations to be “standards compliant,” its requirements will need to be followed.
4. Changes to TIA 1005, Addendum 1 “Industrial Pathways and Spaces”Issue: When talking about the Industrial Equipment Room, say the same as TIA 569-B.1, which is the current environmental spec for industrial spaces.Resolution: They would correct the paragraph on HVAC for the Industrial Equipment room to say that “a mechanism to remove the generated heat shall be included to avoid any detrimental effect to the active equipment.” And that they “…refer to the active manufacturer for specific guidance on tem-perature and humidity limitations.”
Issue: Correct pathway separation for EMI sourc-es…it’s not “0.”Resolution: They would correct separation to match section 5.2.3 for separation from lighting to five inches from fluorescent lighting.
Issue: When talking about what benefits there are to where a telecom enclosure is located, clear up what kind of cabling it can help. (We know that cable be-ing routed to the TE is considered backbone cabling, and cable being routed from the TE is considered “horizontal cabling”.)Resolution: Change one of the reasons it can help to minimize horizontal cabling length.
Issue: Be clear that these are the same as ASHRAE recommendations for heating and air conditioning.Resolution: Under the HVAC section for the tele-communications enclosure use the ASHRAE recom-mendations:Temperature and humidity inside the telecommuni-cations enclosure shall be maintained as follows: 1. Temperature: 5 – 40º C (41 – 104º F) dry
bulb. Reduce maximum dry-bulb temperature 1º C /
300m (1.8º F/1000 ft) above 900 m (3000 ft) altitude.
Minimum temperature with diskette in a drive is 10º C (50º F);
2. Relative Humidity: 8 - 80%; and 3. Maximum dew point: 28º C (82º F).
The group essentially had to work on matching their HVAC requirements with ASHRAE’s to make this standard correct.
See illustration on page 13.
➣ ACTION: TIA 1005-1 would go out for another SP (full industry) ballot and be handed over to 42.9 to check ballot comment resolution.
What You Need to Know
Remember, they will recommend this goes to be pub-lished when TIA-1005 (out of 42.9) is available.
5. TIA 569-C (3rd revision) Update Plan
The update plan used:• Recommendations of the Conduit Fill Task Group.• BAS commercial building content placed in annexes.• Access provider spaces, service provider spaces,
common equipment rooms, common telecommu-nications rooms, MUTOA’s and CP’s considered generic.
• “Green Initiative” or Stewardship text in foreword.• No commercial building terms.
BAS annex was removed and forwarded to TR-42.1 for inclusion in TIA-862-A.
➣ ACTION: After the update plan had been explained, the writing of the 3rd revision of TIA 569 (C) was approved.
What You Need to Know
New actions agreed to were:1. There would be no informative Annex on Conduit
Fill.2. Content specific to BAS cabling would be removed.3. Content specific to commercial buildings would be
removed.4. TR 42.3 would develop an addendum for commer-
cial buildings, after approval.5. Schedules would be developed that would allow
569-C and 569-B.1 to be published at the same time.
6. Commercial building HVAC requirements used would be used as “default” HVAC requirements for generic spaces.
7. Verify whether the temperature for the telecom enclosure is with or without active equipment.
8. TIA 568-C.0 would be referenced for the MICE table.
9. Pathway separation requirements for E2 and E3 electrical environments would be included.

TIA TR 42.4 Outside Plant Mesa, AZ, February 4, 2009The TIA TR 42.4 subcommittee created the standard TIA 758-A for Customer-Owned Outside Plant Tele-communications Cabling. At this first Plenary meeting of 2009, the group discussed the position of the 758 standard in relation to other TIA TR 42 standards and whether it should be updated.
Meeting Topics 1. Hierarchical Position of TIA 758-A
(Outside Plant Cabling) 2. TIA 758-B Plans 3. Next Plenary Meeting
1. Hierarchical Position of TIA 758 (Outside Plant Cabling)
➣ ACTION: The subcommittee would revise Figure 1 and 568-C.0 and C.1 to reflect 758-A as a common standard versus a premises standard. See page six for an idea of the revised drawing.
2. TIA 758-B PlansA review of TIA 758-A showed the need to update the references mentioned and to update the table on Typical OSP twisted-pair cable lengths for specific applications.
➣ ACTION: A draft of 758-B would be posted on the TIA website for members to review, an interim meeting would review any input received, then a “mock” ballot would be issued.
What You Need to Know
This was being updated because it was over five years old and needed to address any technology changes.

TIA TR 42.6 Administration Mesa, AZ, February 3, 2009The TIA TR 42.6 committee created the TIA 606-A standard for “Administration (Labeling) of Telecommu-nications Cabling.” This first Plenary meeting of 2009 also covered the work done in ISO/IEC on “identifiers” and where the TIA 606-B standard was going.
Meeting Topics 1. ISO/IEC’s WG3 Technical Report on Identifiers 2. Development of TIA 606-B 3. TIA Symbols 4. Next Plenary Meeting
1. ISO/IEC’s WG3 Technical Report on IdentifiersDiscussion
• ISO/IEC WG3 has a draft document that draws heavily on our strawman 606-B without the legacy identifiers. The technical Report is SC 25N1612.
• Our subcommittee Chair is also the editor of this ISO document.
• Was it realistic for the U.S. and ISO to be the same or should we come close to understanding their system and merge that into our U.S. docu-ment?
• It would be great if a couple of years from now the nomenclature was the same.
• It would make sense to have a company’s ad-ministrator be able to administer their company worldwide. One command center could do it all.
• This was an opportunity for us to step to the forefront internationally.
➣ ACTION: The Subcommittee would provide comments on the ISO/IEC document on Identifiers (TR 14763-2-1) via the U.S. TAG and would defer action on TIA 606-B until ISO/IEC’s document was completed.
2. Development of TIA 606-B Discussion• Existing shalls and shoulds would be included.• Industrial identifiers would be included.• Now we should incorporate all our comments into
a single TIA 606 position and give that to the U.S. TAG to deliver to ISO/IEC.
➣ ACTIONS: 1. Vote on the updated TIA 606 as a US position
and get comments from our experts and sub-mit along with our doc to US TAG.
2. Via conference call resolve comments and compile all and post on the TIA website.
More Discussion• When the CITG adopts their document, base our
identifier portion of TIA 606-B on CITG’s and then decide if we want to finalize 606-B or wait more to see what ISO/IEC does.
• We are only waiting for this Identifier product and not yet doing anything with 606-B yet.
• Our goal should be to have only part of 606-B the same as the ISO/IEC (international) standard.
3. TIA SymbolsDiscussion• Compile all the symbols in TIA 606 now and send
them to the Definitions Committee, TR 42.5• TR 42.5 would keep up with the symbols.• TIA 606-B would be the only published docu-
ment that showed the symbols.
➣ ACTION: Send all our symbols in TIA 606 to the Definitions Subcommittee, TR 42.5, for review and finalization.

TIA TR 42.8 Optical Fiber Cabling Mesa, AZ, February 3, 2009The TIA TR 42.8 committee for “Telecommunications Optical Fiber Cabling Systems,” provides research, test-ing, and presentations on optical fiber being used in per-formance standards. This committee has now developed the TIA-568-C.3 standard, “Optical Fiber Cabling Components” which is an update to 568-B.3 published in April 2000. This first meeting of 2009 discussed TIA 568-C.3, the new “Optical Fiber Cabling” stan-dard, and what was going on with OM4 fiber.
Meeting Topics 1. TIA 568-C.3 Status 2. OM4 Fiber Status 3. IEEE 802.3ba (40 and 100 Gig Ethernet)
Array Connectivity 4. Next Plenary Meeting
1. TIA 568-C.3 Status➣ ACTION: Errata corrections in a new version of TIA 568-C.3 were published and to be mailed to buyers. (There was no separate errata.)
2. OM4 Fiber StatusDiscussion• The first ballot for the OM4 fiber specification
opened 12/19/08 (PN 3-0356).• This ballot closed January 19, 2009. • The controversy was whether the OM4 was a cable
type or a fiber type.
➣ ACTION: TR 42.12 would work with this.
3. IEEE 802.3ba (40 and 100 Gig Ethernet) Array Connectivity An update on the IEEE acceptance of the pin-out variants for 40 Gbps and 100 Gbps parallel optics using the MPO connector was presented:• IEEE creating 40 and 100 Gig Ethernet applica-
tions. • Currently, IEEE included a clause that said the op-
tical signals that resided in the transceiver were… (This was left blank because it was undefined.)
• If no contribution was brought in, this would be left undefined and therefore there would not be a completed interoperable standard.
• A contribution had been brought in for Clause 86.5.1 with pin assignments for both speeds that was accepted by IEEE 802.3ba, with minor modi-fications.

TIA TR 42.9 Industrial Building Cabling Mesa, AZ, February 4, 2009The TR 42.9 subcommittee is developing the TIA 1005 standard for the industrial telecommunications infrastructure. This brought in new effects from noise, dust, distance, vibration, EMI, etc. This standard refers to cabling for industrial manufacturing—on the fac-tory floor. During this first Plenary meeting of 2009, the subcommittee covered an ODVA (Open DeviceNet Vendor’s Association) update that shows the work they’re doing on industrial standards, the work done by the POF Task Group before this meeting, and what the next update of TIA-1005 could cover.
Meeting Topics 1. ODVA Industrial Work 2. 1mm POF Task Group Input 3. TIA 1005 Update Plan 4. Next Plenary Meeting
1. ODVA Industrial WorkUpdate • ODVA published their technical standard twice/
year.• The November 2008 standard supported POF
(Plastic Optical Fiber) for 10/100 Mbps networks. It included connector-less transceivers. Still POF didn’t go a long distance.
• They were working on Grounding and Bonding for industrial.
• A JSIG (Joint Special Interest Group) had released a MICE report.
• A JSIG was working on the third revision of its Planning and Installation Manual—to be com-pleted in 2009.
• Ethernet was being adopted for additional field buses under IEC; release of document expected 2010.
• After above release, they were to begin Edition III.• See SC65/JWG10 list of networks they support.
2. 1mm POF Task Group InputUpdate• The Task Group was still in effect even though
1mmPOF was removed from TIA-1005. • There could be a technology update for next revi-
sion of 1005.• ISO/IEC 60793 supports POF for 100 MHz over
100 meters. (This was taken out of TIA 1005 be-cause there were no test procedures, etc.)
• This Task Group was continuing to monitor stan-dards for 1mm POF adds/changes and would pre-pare a proposal for 1mm POF for TIA 1005 (to include pulling tension, bend radius, testing, etc.).
• This work will be kept in this TR 42.9 group.• What is different now is that distance is different
and perhaps 65 meters would work in the indus-trial (versus commercial) environment.
• Industrial needs to decide whether POF is accept-able to TIA 568-C.0. If Industrial wants to add this as a media, they would need to do some more work. The Task Group seemed to be going down that path.
• ISO/IEC has information on A4a and A4d POF.• What had happened to make this more viable
was that MOST (the Media Oriented Systems Transport protocol from Europe) used Ethernet and when POF for the lower bandwidth was de-veloped, that led to the higher bandwidth over POF. This was pushed by Europe—a technology changed.
➣ ACTION: TR 42.9 would start working on POF for 568-C.3 with the POF Task Group.
3. TIA 1005 Update PlanUpdate• TIA-1005 would remain a TIA 1005 standard
(not a new 568 series such as D).• Since 568- C.0 and C.1 had been approved for
publication and would soon be stabilized, it was proposed TR 42.9 open up a new PAR (project) and decide what to do:
• Update the standard with the inclusion of AD1 for Pathways and Spaces.
• Update with new emerging technologies (POF, etc.)
• Include other emerging topologies for Ethernet which affect the way the network is looked at. In-stead of having a switch outside, the device would be inside with daisy chaining to other devices where switches are inside). This is simply making the switch smaller (less ports) and it is embedded in the hardware. Everything is distributed. We still could make use of the generic structure to get from point A to point B.
• These were just a few things they wanted to look at…whether they were adopted or not.
➣ ACTION: The revision project was approved unanimously.

TIA TR 42.16 Bonding and Grounding Mesa, AZ, February 2, 2009TIA continues working on updating the Grounding and Bonding standard, “607-A.” This first Plenary meeting of 2009 covered sections being developed for the ground bar, testing and verification, design, an EMI Annex, and use of the term MESH-BN. The grounding and bonding standard that exists now is ANSI/TIA/EIA-J-STD-607-A.
Meeting Topics 1. 607-B Testing and Verification Content 2. 607-B Design Content 3. Ground Busbar Investigation 4. EMC Annex 5. Term: MESH-BN 6. Document Plan 7. Future Work 8. Next Plenary Meeting
1. 607-B Testing and Verification➣ ACTION: The section of Testing and Verification would be drafted and discussed via conference call.
2. 607-B Design Content DiscussionThis would involve information as in NECA/BISCI 607. It would cover: • Computer room • Cabinets and racks• Equipment in cabinets and racks• Cable ladders, cable runways, conduit, pipes, and
building steel• The mesh-bonding network• Bonding conductors for connections to the mesh-
BN or RGB• Telecommunications equipment bonding connec-
tor (TEBC) • Separation • Bonding equipment cabinets/equipment racks to
the TEBC • Structural bonding of equipment cabinets/equip-
ment racks
➣ ACTION: This draft would be redone to be clearer and would be discussed at a later time. No other action was taken at this time.
3. Ground Busbar Investigation a. To be used in other countries, the group de-
cided to write this for a busbar with a mini-mum of 80% copper. (This would open it up to other alloys with at least 80% copper.)
b. A proposal was made to include a mechanical connection (revolutionary for America).
c. The 2" busbar was considered because you could
• Make an effective electrical connection with it.
• Use it for performance monitoring. • Use it for an interface for each end point.
d. There still was the issue that the international standard did not require a mesh network.
➣ ACTION: This subject was left undecided as to any size busbar.
4. EMC Annex Presentation a. The group was advised to use balanced twisted-
pair cabling to reduce EMI (electromagnetic interference).
b. The ultimate objective was to reduce noise.
➣ ACTION: A Task Group was created to work on this and get a draft ready for the next Plenary meet-ing, August 2009.
5. Term: MESH-BN➣ ACTION: A Task Force would propose new terms and explain their relationship with other known terms.
What You Need to Know
The term SBG (Supplementary Bonding Grid) was brought up as that being generally placed under a raised metal floor or above the racks/cabinets com-plex to a supplementary function to the serving power circuit’s equipment grounding protector... and they con-sidered renaming that the “Mesh-BN” but had problems because the MeshBN did not include Star grounding and IBDN. They needed somehow to point out that the MeshBN was not the only bonding network.
➣ ACTION: A Task Group would study whether “MESH-BN” is the correct terminology. The objec-tive of the Task Group was to recommend a new sec-tion just for Mesh-BN and then to include all types.

IEEE 802IEEE, the Institute of Electrical and Electronics Engi-neers, Inc., is a not-for-profit association that publishes technical documents, holds conferences, and develops standards. IEEE 802 is the LAN/MAN Standards Committee for Layers 1 and 2 of the OSI (Open System Interconnection) reference model.
Layer 1 is the physical layer (hardware including ca-bling) that applies to the LAN (Local Area Network) defined as a campus, and MAN (Metropolitan Area Network) for intracity networking. Light or radio sig-nals are conveyed through the network at the electrical and mechanical level. It consists of the electromagnetic and physical aspects of a device, a transmission medium (the cable), and the interface between them (connectors or NICs [network interface cards]). The PHY refers to anything relating to hardware (cables, connectors, cards) that is enabled to send and receive data.
Layer 2 is the Data Link Layer where data packets be-come bits and carry transmission protocol information to 1) handle errors in the physical layer; 2) provide flow control, and 3) provide frame synchronization. This data link layer is made up of two sublayers—the Me-dia Access Control (MAC) layer and the Logical Link Control (LLC) layer. That MAC sublayer controls how we access data and gives permission for its transmission. The LLC layer controls frame synchronization, flow control and error checking.
The other five layers of the OSI model are Layer 3, the Network Layer (where switching and routing is provided and logical paths [virtual circuits] are created that send data from node to node); Layer 4, the Transport Layer (where data is transferred [transparently] between sys-tems/hosts and end-to-end error recovery and flow control is performed); Layer 5, the Session Layer (where connec-tions between applications are managed); Layer 6, the Presentation Layer (where data is transformed into the form that the application layer can accept when that data is different;) and, Layer 7, the Application Layer (where application and end-user processes are support-ed—everything at this layer is application specific).
IEEE 802.3—EthernetIEEE 802.3 is referred to as the Ethernet standard (an application). This includes projects for 1 gigabit Ether-net transmission (1000 Mbps) over both fiber (802.3z-1998) and copper (802.3ab-1999). The standard for DTE Power over Ethernet (802.3af-2003) has been completed and published; so has Ethernet in the First Mile (802.3ah-2004); the standard for 10 gigabit Eth-ernet over coaxial cable (802.3ak-2004), and the stan-dard for 10 gigabit Ethernet over fiber (802.3ae-2003).
Committee work continues with the Power over Ether-net Plus Task Force (802.3at) who have now settled on a slightly higher minimum capability than 24 watts, the Energy Efficient Task Force (802.3az) finding ways to reduce energy, the 10 Gigabits per second EPON group (802.3av) and, there is a Higher Speed Study Group (802.3ba) that is studying 40 Gbps and 100 Gbps over fiber and copper.
Current Phy-Related Work Items
802.3at Power over the Ethernet Plus Task ForceThe IEEE 802.3 working group has formed this Higher Speed Task Force to evaluate the requirements for the next generation of Ethernet technology at 40 and 100 Gbps.
Status• The current first round of sponsor ballots are clos-
ing and they are hoping for ratification in Septem-ber 2009.
• There have been no real technical changes except the 24 watt minimum objective now has a real value that works out to 25.5 watts (which beats the objective).
802.3az The Energy Efficient Task Force This Task Force work is to extend the number of ap-plications that could benefit from more power being delivered over Ethernet.
Goals• Reducing power during low-link utilization• Remain compatible with existing cabling infra-
connectivity)• 10GBASE-KX4 (10 Gbps over 4 lanes for
backplane connectivity)
Discussion• Optical PMDs were not included and there was
no particular reason except that a proposal was not brought in in time to change the project authori-zation request.

• There was a growing interest in low power idle for optical PMDs, but that would need to be a new project.
• Copper PMDs represented a broad market poten-tial, which is one of the criteria needed to get a project started in 802.3.
• The data center (still copper with shorter dis-tances) did not use auto-negotiation to manage its power. It was used to advertise low power idle capabilities, but not to “manage” power.
Status• They were reviewing comments to Draft 1.2.1 and
Draft 1.3 would be ready for review in April 2009.• 802.3az was expected to be approved in September
2010 (this slipped due to additional work required to get backplane Ethernet ballot-ready, as well as several unspecified values that were remaining.)
802.3av 10Gbps EPON (Ethernet Passive Optical Network) Task ForceThis is to support subscriber access networks using point-to-multipoint topologies on optical fiber.
Status• The Task Force was currently working on develop-
ment of the next-generation, 10 Gbit/s capable Ethernet Passive Optical Network (10G EPON) specifications, anticipated to bring a new flavor of PON technology to life by 2009. This would be applicable in multiple environments to support bandwidth-intensive applications that would re-quire fast, reliable, scalable, first-mile connections. Such applications included Broadcast TV (expand-ed HDTV content), IPTV, time-shifted TV, rich unicast based VOD (Voice on Demand) content libraries, 3D Online Interactive Games, UltraHigh SpeedInternet, Personal Video Casting, and many more applications.
• Draft 3 of this application standard, released 1/16/2009, was in its ballot process.
• The last technical changes had been made and it was planned to go to RevCom (the Standards Board Review Committee) in July with the ex-pectation that the standard would be approved in September 2009.
802.3ba Higher Speed Ethernet Task ForceThe IEEE 802.3 working group has formed the Higher Speed Task Force to evaluate the requirements for the next generation of Ethernet technology at 40 and 100 Gbps.
Status• Draft 1.2 was available as of February 10, 2009.• Approval of standard expected in June 2010.• This new standard’s goal is to:
1. Provide Physical Layer specifications which support 40 Gb/s operation over:- at least 10km on SMF- at least 100m on OM3 MMF- at least 10m over a copper cable assembly- at least 1m over a backplane
2. Provide Physical Layer specifications which support 100 Gb/s operation over:- at least 40km on SMF- at least 10km on SMF- at least 100m on OM3 MMF- at least 10m over a copper cable assembly
