PlatformMSS 9400 Platform (CD6394)

This feature introduces an evolution to the successful Multiservice Switch7400 platform. Based on the Multiservice Switch 7480, it provides asystem with 14 FP slots and 2 CP/Fabric (CPF) slots. It also introduces anew CP/Fabric card based on new processor daughter cards. The CPFFabric terminates and switches 800 Mbps of traffic from each slot.

The new architecture will allow the direct re-use of most existingMultiservice Switch 7400 FPs, features and services. Please reference theMultiservice Switch 7400 and 9400 NTPs for specific information aboutwhich FPs are supported. This new platform is fully supported by thestandard PCR software stream and is fully integrated in MDM.

2pGE for MSS 7400 and 9400 (CD7074)This feature introduces a new 2-port Gigabit Ethernet (GE) (NTNS70AG)with optical interface on Multiservice Switch 7400 and 9400 platforms.In general, the FP supports the same services as the 4pGE on theMultiservice Switch 15000. The following are key capabilities:

• 2 full-duplex ports

• Small form-factor pluggable (SFP) optics [SX, LX, and ZX]

• IEEE 802.3 compliant

• IEEE VLAN support (802.1Q)

• LAG (802.3ad)

• Port and VLAN statistic monitoring

• ATM Pseudowire capabilities

ATM/EthernetEgress p-bit IP Marking (CD6014)

The Ethernet p-bits egress marking feature builds on and enhancesthe traffic management capability of the Ethernet RFC2547 and VIPRnetworking solutions. The use of the p-bits will enable the support ofmultiple service classes into a single MSS Ethernet link. The EthernetUser Priority bits field (commonly referred to as p-bits) in the header ofIEEE 802.1Q tagged frames may be marked by the MSS network basedon layer 3 QoS indicators (packet’s IP DiffServ value or MPLS EXP bitsvalue) to communicate the frame class of service and/or drop precedenceto the optical Ethernet network. This feature is available on both the MSS7400 4pEth100BaseT and 8pEth100BaseT FPs, on the MSS 9400 2pGeFP, and on the MSS 15000 and 20000 4pGe FP

Ethernet SNMP MIB Support (CD6994)This feature introduces Enterprise MIB support for the following MIBs andcomponent classes.

Nortel-MsCarrier-MscPassport-LanDrivers MIB

• LanApplication

• LanApplication Framer

Nortel-MsCarrier-MscPassport-LanDrivers-LanBase MIB

• LanApplication EthernetStatistics

• LanApplication Vlan

• LanApplication Vlan EthernetStatistics

• LanApplication EthernetPolicy

Wireless Backhaul Clock Synch (CD7034)This feature provides a timing service for Multiservice Switch wirelessbackhaul synchronization. The feature enhances the ATM and/or TDMPseudowire (PW) solutions by distributing the clocking information fromthe RNC-site Multiservice Switch Gateway to the remote cell-site devicesover the IP/Ethernet access network.

The Multiservice Switch Core Pseudowire node obtains its Master clockfrom the Network Clock Synchronization (NCS) system. This clock isthen distributed to the remote cell-site gateways using a special TimingPseudowire over the IP/Ethernet network. The cell-site gateways recoversthe master clock and uses it as the Transmit clock on the outgoing E1/T1interfaces to the 2G and 3G wireless stations.

This feature requires hardware capabilities introduced on the 4pGE FPversion NTPN49AG.

MaxVCC Increase for MS3 1pOC48 FP (CD7156)This feature increases the maximum supported connection number from16000 to 45000 in the 1-port OC-48/STM-16 mode of the NTHW46 FP.

ATM Call Redirection for EVLS (CD7157)This feature addresses the issue of resiliency of the destination CPEdevices by provisioning two destination addresses for an EVC SPVC:a primary address and a secondary (backup) address, for connectionsoriginating as part of the EVLS application. The connection is first routedto the destination using the primary destination address, and if it isunsuccessful, the secondary address is used.




.

IP 15

This feature is supported for SPVCs under a LAN/VLAN EVC and ETSEAtmTrsp generated SPVCs.

CESDS0 Channelization on 4pOC3/STM-1ch CES FP (CD7754)

This feature introduces basic structured CES services to the 4 port OC- 3Channelized CES/ATM/IMA FP (NTPN27).

DS0 Channelization on 2pSTM-1 (CD7755)This feature introduces basic structured CES services to the 2 port STM-1Optical Channelized CES/ATM/IMA FP (NTNQ96).

IPIP Multicast Support on 4p/8pEth100BaseT (CD4034)

This feature enables the existing VIPR IP Multicast solution onthe Multiservice Switch 7400 and the Multiservice Switch 94004pEth100BaseT (NTNQ95xx) and 8pEth100BaseT (NTNQ92xx) EthernetFPs. This matches the capability already provided by other FPs.

IP Multicast support for 4p/8pEth100BaseT FPs is only implemented atport level LAN mode. No VLAN support is provided.

As well, this feature also provides IP Multicast on VpnXc card forMultiservice Switch 15000 and Multiservice Switch 20000.

IP Flow Classification for PQC (CD4134)This feature enables Service Providers to classify IP traffic arriving onsupported VIPR VR, RFC 2547 VRF, or RFC 2764 CVR PQC FP IPinterfaces using multi-field classification.

User-configured rules can be defined to mark the incoming packet’s DSCPbased on a combination of Layer 3 and 4 protocol header fields, such asTCP and UDP port numbers. The action resulting from classification is thepossible modification of the packet’s PHB and DSCP.

VIPR XC SNMP MIB Support (CD5634)This feature enables VIPR specific standard MIBs access when VIPRsolution is residing on XC. The set of standard MIBs supported isequivalent to those supported for the customer VRs in the VR componentdata model.

IP Flow Filtering for PQC (CD6354)The IP Flow Filtering feature enables the Service Provider to restrictadmission of IP packets arriving on VIPR, RFC2547, and RFC2764solutions on PQC2 and PQC12 FPs on the Multiservice Switch 7400,9400, 15000, and 20000 platforms.




.


Filter profiles are used to define a collection of user configurable rulesthat specify match criteria on combinations of the following fields: DSCP,IP protocol (e.g. TCP, ICMP), IP source and destination, and TCP/UDPport source and destination. Wildcarding and ranges are supported forLayer 3 and 4 packet fields. Each rule has a permit or deny action, and auser-configurable priority number. Any number of interfaces can share onefilter profile configured on the same VR or VRF.

RFC 2547/MPLSRFC2547 Route Reflector (CD6454)

This feature introduces Route Reflectors in a BGP/MPLS VPN network(RFS 2547 IP VPN solution) eliminating the need for the Service Providerto maintain a fully meshed network, hence improving the scalability of thenetwork. MPLS VPN route reflector deployments can be done in one oftwo ways. In both cases an eXtender Card (XC) is required.

Dedicated Multiservice 7400/9400:

In this deployment, the 7400/9400 is running the MPLS VPN route reflectorfunctions exclusively. Networking interfaces can be FE or supported ATMMPLS PQC FPs.

Multiservice Switch 15000, or 20000, P node with MPLS VPN routereflector:

In this deployment, a Multiservice Switch 15000, or 20000 P node can runthe MPLS VPN route reflector functionally. PE node functionality is notsupported with MPLS VPN route reflector functionality.

ATM Pseudowire with Cell Concatenation on GE (CD7075)This feature delivers the cell concatenation functionality as anenhancement to the ATM Pseudowire solution delivered in PCR 8.2(CD6814). Cell concatenation allows for multiple ATM cells to be placedinside one pseudowire packet leading to increased Ethernet link efficiency.

TDM Pseudowire over IP Tunnel on GE (CD7077)This feature enables the wireless network operators to replace existingexpensive TDM facilities with less costly IP/Ethernet transport. This featurebuilds on the Multiservice Switch Circuit Emulation Service (CES) overATM and ATM Pseudowire over IP Tunnel on 2pGE and 4pGE featuresenabling the consolidation of 2G and 3G traffic over the same packetnetwork infrastructure.




.

System 17

The feature supports transport of ingress TDM bits (including framing bitsif any) from each T1/E1 over a single PW connection. It also supportstransport of bits from N of DS0 timeslots in a T1/E1 frame over a singlePW connection.

ATM Pseudowire over IP Tunnel Enhancements (CD7535)This phase of the solution implements a number of significantenhancements to the ATM Pseudowire solution delivered in PCR 8.2.(CD6814) The enhancements increase network efficiency, solutionreliability, and network scalability.

The major enhancements are:

• Carrier Grade (hot CP switchover)

• QoS (user-configurable DSCP marking)

• Networking Enhancements (dynamic IP Routing, multiple RTRs)

• Platform (XC) support

• Scalability

• OAM Enhancements (FP fault propagation & BFD enhancements)

• Statistics enhancements

• Sequence number optionality

Dynamic CAS lspDB Display (CD7814)This feature enables the Multiservice Switch network operators todisplay, monitor, and examine MPLS Transport LSPs within MPLSnetwork and/or RFC2547 network. It meets the increasing demandsof needing to know real time dynamic MPLS and/or RFC2547 networktransportation information for network operations and maintenance,network troubleshooting, network performance assessments andevaluations.

SystemMSS File Checksum (CD2867)

This feature implements a CRC (Cyclic Redundancy Check) mechanismto detect corrupted files that were transferred to the Multiservice Switch.The feature applies to:

• Application files transferred to the Multiservice Switch using the CASinterface.

• Provisioning files which were backed up off-switch and then transferredback to the Multiservice Switch via FTP.




.


Provisioning File Protection (CD7158)This feature expands the MSS File Checksum feature (CD2867) to coverprovisioning files of type asciiFlat. This feature also introduces an adminlevel provisionable attribute under the prov component which, when set,only allows provisioning view operations to proceed when the associatedprovisioning files have been saved with a checksum.

Standby CP PLL Integrity (CD7494)The Standby CP PLL Integrity feature enhances the visibility of the standbyCPs’ clock integrity. With this feature, if there is no proper clock sourceon the standby CP, the active CP cannot perform a CP switchover. Aswell, the feature introduces an automatic mechanism to switchover to thestandby CP if the network clock sync is lost on the active CP.

Enhancements in PCR 9.1 19

Q01464460 FE Hardware limitation when exceeding 2000 VLANsA new Engineering Alarm is introduced by this enhancement. MultiserviceSwitch 4pEth100BaseT and 8pEth100BaseT Functional Processors have ahardware limitation. The recommended number of VLANs per card is nomore than 2000. On these Functional Processors the new EngineeringAlarm is raised when there are insufficient resources.

Multiservice Switch 4pGe Functional Processors have a similar hardwarelimitation. The recommended number of VLANs per card is no more than4000. On these Functional Processors the new Engineering Alarm israised when there are insufficient resources.

The unexpected Ethernet services media comes up as "Locked/Disabled/Idle" and can not recover automatically. For recovering from theresource exhaustion, please refer the NTP’s.

Q01533652 Power on reset alarmDescription: This enhancement appends text to the existing card enablealarm 70120100, for ppc cards only, when the last card reset was apower-on reset. When the last card reset was not a power-on reset, thealarm appears unchanged. The alarm on i960 cards is unchanged - theinformation about the type of reset is not available on i960 cards, so thisenhancement is not supported on i960.

Q01614432 MCDN Connectionless timersDescription: The MCDN connectionless timers values are changed to beglobal variables instead of constants.

Q01620787 Proxy ARP support for Bridge TerminationDescription: This enhancement modifies the existing proxy ARPimplementation so that Bridge Termination is also supported.

Q01651822 Active CP does not raise PLL alarmsDescription: This enhancement updates the message alarm text for betterfault isolation and faster service recovery.

Q01651999 MLFR group needs an operational link speedDescription: For consistency with IMA and MLPPP, this enhancementintroduces an additional operational speed attribute to show theaggregated speed for the number of links in the MLFR group. Thisattribute will enable a customer to quickly determine if they have an issueon one of their links without having to drill down to the lk/* component.This applies to both 7400, 9400 and 15000 that supports MLFR




.


Q01651709 LAG group needs an operational lagGroupSpeedDescription: For consistency with IMA and MLPPP, this enhancementintroduces an additional operational speed attribute to show theaggregated speed for the number of links in the LAG group. This attributewill enable a customer to quickly determine if they have an issue on one oftheir links without having to drill down to the lk/* component. This appliesto both 7400, 9400 and 15000 that supports LAG.

Q01652010 Availability does not show degrade when a link in LAGgroup is locked

Description: When a link under LAG group is locked or disabled, theavailabilityStatus attribute of LAG group does not show “degraded”. Forconsistency with IMA and MLPPP, this functionality will enable a customerto quickly determine if one of the links under LAG group is having an issue(i.e. locked or physically down) without having to drill down to the lk/*component. This applies to both 7400, 9400 and 15000 that supports LAG.

Q01679204 Oamenet minor alarm to be raised to major when astandbyline is out of service

Description: This enhancement raises a Oamenet minor alarm to a majorwhen a standby line is out of service.

Q01717336 Add MAC mod sh hardware failure precheck duringupgrade and CPSO scenarios

Description:This enhancement prevents a CP switchover (eithercontrolled, or during a migration) when there is a MAC address modulehardware fault present in the system.

This enhancement prevents a CP switchover (either controlled, or during amigration) when there is a MAC address module hardware fault present inthe system.

If a MAC address module hardware fault is present when any of thefollowing commands are issued, the command will fail with the proper errorresponse:

• switch lp/0

• reset/restart lp/0

• reset/restart sh ca/<active CP card num>

If a MAC address module hardware fault is present when any of thefollowing operations occur, activation will fail with the proper errorresponse:

• Hitless Software Migration, (only on MSS 15000/20000)

• Hitless Software Removal on CP (only on MSS 15000/20000)




.

Enhancements in PCR 9.1 21

• Hitless Software Patching on CP (only on MSS 15000/20000)

• Classic migration

• Warm software migration (only on MSS 7000)

Q01717337 MAC address card/terminator cardDescription: This enhancement reduces the interval for checking theMAC address card/terminator card from every 2 hours to every 30 minutes.

Q01736275 VNET CAS (Channel Associated Signalling) enhancementDescription: This enhancement adds a new value to the callRoutingattribute under vroute idm. This value is used only in the case of CASsignalling. When the CAS PBX seizes a channel, if digits are provisionedunder the idm component, the Multiservice Switch will insert the digits andthen route the call.

Q01736317 NIS does not support the user-to-user IE in the SETUP orDISCONNECT messages

Description:The enhancement provides the following support:

• codeset 0 user-to-user IE in the Setup and Disconnect messages;

• the forwarding of UUI in the first call clearing message(Disconnect),while the call is still in the call proceeding state, prior to the active state;

• the minimum length for UUI IE - 35 bytes;

• the maximum length for UUI IE - 131 bytes.

Q01736728 PppIwf needs a provisionable attribute to respond in theIPCP negotiation of IP-Address option

Description: This enhancement creates an IP address provisionableattribute under the PppIwf NCP component, which will store the remoteIP address and be used to respond to the IP Address option of the IPCPconfigure request message.

Q01806186 Hitless BTDS with NSAP for CP Equipment ProtectionDescription: This enhancement supports BTDS with NSAP for a hot CPswitchover.
