1-2 Introduction


The OME6110 provides dramatic cost savings over currently deployedsolutions and offers deployment flexibility at multiple levels, including:

Service flexibility : Full mix of services including E1/DS1, E3/DS3 andEthernet. SDH/SONET services are also planned in the next release.

Reach flexibility : Small Form-Factor Pluggable (SFPs) optics are used,allowing each shelf to be configured for the distance and wavelengthrequired.

Protection flexibility : Can be deployed with or without line protection.Both 1+1 MSP/APS and SNCP/UPSR network protection protocols aresupported.

Interoperability flexibility : Can be networked either with otherOME6110 network elements, or subtended from other Nortel opticalproducts, such as OM3000, OM4000 or OME6500.

Management flexibility : The OME6110 is fully integrated into Nortels

Optical Network Manager with OMEA. The OME6110 can also bemanaged from an HTTP web-based craft user interface running on thenetwork element. In addition, SNMP alarm traps are supported, enablingOME6110 fault management from SNMP management systems.

Data communications flexibility : The OME6110 can be managed overeither OSI or IP DCN networks. Path DCC capabilities are also providedfor extending management reach over third-party networks.

The OME6110 is a carrier grade platform that builds upon the solid reputationfor dependability of Nortel Networks' widely deployed optical networkingproducts. The various protection options offered by the OME6110 furtherenhance the dependability of service transport. For access head end

applications, service traffic can either be connected via sub-networkconnection protection (SNCP)/unidirectional path-switched ring (UPSR) orvia protected point-to-point 1+1 connections.

Introduction 1-3


OME6110 applicationsThe OME6110 offers significant value across a range of network applications.The principal OME6110 applications are:

Feeder for Metro Optical networks : The OME6110 can be subtendedfrom Nortels larger Optical platforms to collect E1/DS1, E3/DS3 andEthernet traffic from the Access Edge. Its small footprint and low pricemake it well suited for smaller customer locations where a full sizeSDH/SONET multiplexer can not prove-in. The OME6110 can besubtended either in a SNCP/UPSR or 1+1 MSP/APS configuration. Thecapability to manage OME6110 using path DCC bytes also allows it to bemanaged remotely over leased STM-1/OC-3 circuits. The RegeneratorSection/Section and Multiplexor Section/Line overhead tunnel capabilityprovides further flexibility in managing other SDH/SONET equipmentwithin the same ring.

Private Enterprise Networks : The OME6110 can be deployed in smaller

private networks providing transport of E1/DS1, E3/DS3 and Ethernetservices between sites. A light weight management solution is available forsuch applications consisting of a web-based craft interface running on theOME6110 for NE provisioning and SNMP north bound interface forreporting alarms to a generic SNMP alarm browser.

Wireless Backhaul : The OME6110 is also well suited for wirelessbackhaul applications where both space and cost are paramount. TheOME6110 can be used as a cost-effective backhaul of todays E1/DS1s andwill support the 3G network transition to Ethernet.

OME6110 service interfacesOME6110 offers transport and aggregation of asynchronous private lines,SONET/SDH, and Ethernet. The OME6110 supports three basic categories ofinterface:

PDH

16 E1/DS1 ports are offered as part of the base OME6110 chassis. Theoption slot can be equipped with a tributary circuit pack offering either28 additional E1/DS1 ports or 3 E3/DS3 ports.

Ethernet

An 8-port 10/100 Base-T Ethernet Private Line (EPL) circuit pack isavailable in the current release. In future releases, a GE EPL circuitpack and a 10/100/1000 Layer 2 VPN circuit pack will also be offered.

SDH/SONET

STM-1/OC-3 client interfaces are being introduced in release 2.2.

1-4 Introduction


Small form-factor pluggable interfacesThe OME6110 uses small form-factor pluggable (SFP) interfaces to deliveroptical rate and reach flexibility on a per port basis for the line interface.

As of release 2.1, the OME6110 offers the following SFP interface types:SR-0, SR-1/I1.1, IR-1/S1.1, LR-1/L1.1, LR-2/L1.2, CWDM, STM-1e,Bidirectional.

Nortel Networks has been collaborating closely with leading SFP vendors toimprove the reliability, robustness and manageability of SFPs. The use of suchcarrier-grade SFP technology enables service providers to enjoy the flexibilityof provisioning the interfaces per the requirements of the specific application.

SFPs also reduce the cost of sparing by enabling an upgrade of the optical lineinterfaces as they become readily available.

Figure 1-2Pluggable optical modules summary

Point-to-point optical broadband servicesThe OME6110 uses GFP, VCAT and LCAS standards for the mapping andtransport of Ethernet services.

GFP provides an efficient mechanism for Ethernet transport over aSDH/SONET core network via efficiently mapping varying client signals intoSDH/SONET VC-12/VT1.5 and VC-3/STS frames. GFP mapping enablesefficient network resource utilization with low overhead requirements, andlimited over-provisioning with VCAT. End-to-end framing providesdemarcation for the Ethernet signal, and enables consistent SDH/SONETbased PMs through the network. Since the Ethernet is mapped intoSDH/SONET frames, the existing core network can transport the Ethernetframes transparently.

Introduction 1-5


The OME6110 also supports Virtual Concatenation (ITU-T G.707 compliant)with support at the VT1.5-nv and STS-1-nv SONET rates as well as VC-12-nvand VC-3-nv SDH rates. A maximum of 48 ms of differential delay issupported.

Along with VCAT the OME6110 also supports value added capabilities suchas soft protection via Link Capacity Adjustment Scheme (LCAS - G.7042).LCAS has been specifically developed to overcome static link provisioning. Itenables service providers to efficiently offer dynamically-allocated bandwidthas well as hitless throttling of the capacity of a VCAT link (or VirtualConcatenated Group) by adding or removing STSs or VCs as required.

LCAS provides a soft protection and load-sharing mechanism to automaticallydecrease the link capacity if an STS or VC path experiences a failure andautomatically increases the link capacity when the network fault is repaired.This capability provides an extra level of network and service resiliency by

facilitating the support of SLAs through graceful service degradation whennecessary. In particular, during network and service restoration LCAS cansupport hitless bandwidth expansion and contraction thereby reducing serviceinterruptions in the event of network failure and easing network operations andmaintenance actions.

TDM switchingIn the OME6110 architecture, traffic is switched between working andprotection line interfaces via the switch matrix in the base chassis.

All ingress service traffic is mapped into VC-12/VT1.5, VC-3/STS-1 orVC-4/STS-3c containers and directed towards the switch matrix which is

configured to switch the incoming traffic to the appropriate line interface. Theswitch matrix allows any input channel to be connected to any output channel.Hairpinning is also supported between client ports.

Network managementThe OME6110 is managed as an integral part of Nortel Networks' marketproven end-to-end optical portfolio management capabilities. This frameworksupports a sophisticated and highly customizable desktop providingcentralized topology view and fault management, centralized launch pad for afull suite of management applications, easy to use nodal managers andseamless network element reach-through for Nortel Networks' completeoptical networks portfolio. These network management capabilities aresupported by the Optical Manager and Optical Application Platform, such asOMEA and Optical Network Manager ( formerly known as Preside ), inalignment with Nortel Networks overall optical networks portfolio.

Filler faceplateThe filler faceplate is required to cover the unused optional service slot. If noadditional circuit packs are required a filler faceplate must be used to cover theempty slot to ensure proper airflow through the base chassis and to ensure EMI

compliance. Figure 4-2 on page 4-3 displays the base chassis with a fillerfaceplate installed over the optional service slot.

Refer to Ordering information and system engineering rules on page 8-1 forthe associated PEC. The filler faceplate comes equipped with the base chassis,but can also be ordered separately for sparing.

E1 75 ohm termination panelThe conversion from 120 ohm to 75 ohm E1 service interfaces can be achievedfor:

the 16 x E1/DS1 service interface on the base chassis

the 28 x E1/DS1 circuit pack

The conversion is achieved by connecting the Telco connectors of the 16 xE1/DS1 service interface or the 28 x E1/DS1 circuit pack to a 1U high16-channel termination panel. The termination panel is equipped with 16 BNCconnectors. This 75 ohm termination panel can only be used for E1 services.

Note: The 75 ohm termination panel is labeled from 1-16 by default, butincludes an additional overlay label which can be installed by the userwhen connecting the ports 17-28 of the 28xE1/DS1 circuit pack.

A 64-pin to 64-pin male connector cable must be used to connect to the

termination panel. For more information regarding the 75 ohm terminationpanel and the cable pinout information, refer to E1/DS1 cable pinouts andassemblies on page 7-17

6-2 OAM&P description


Global supportOptical Multiservice Edge 6110 is a global platform that can be deployed inboth SONET and SDH environments. The network element (NE) modedetermines the overall function of the network element in either a SONET or

SDH environment.The user uses the Configure Node page from the Local Craft Terminal to setthe NE mode to either SONET or SDH during initial commissioning.

Note: You cannot change the mode from SONET to SDH or vice versawhile in-service. To change the mode of the network element, you mustfirst use the Restore factory default application to delete allconfiguration, events, and PM data. Power cycle the network element andthen use the Configure Node page to enter the required commissioninginformation and NE mode or to restore from a saved configuration.

The NE mode defines the defaults for some provisioning items as detailed inTable 6-2 . Some of these provisioning items can be overridden after the usersets the NE mode.

Note: All other provisioning items are independent of the NE mode (forexample, OAM comms and security).
