New Features and Enhancements in Release 5.0.00
SRME/B
This new card will be an enhancement of the existing SRME card. Like the SRME, the SRME/B is a single-height card, and the two key functions it supports are: T3 interface along with OC-3, as well as BERT, bulk distribution and 1:N redundancy.
There can be up to 2 SRME/Bs per service bay, for a total of up to 4 SRME/Bs per MGX node. With the MGX 8850, the SRME/Bs in slots 15 and 16 support Service Modules in the upper service bay with BERT, bulk distribution and 1:N redundancy, and the SRME/Bs in slots 31 and 32 provide a similar service to the lower bay. With the MGX 8830, a comparable support is provided by SRME/Bs installed in slots 7 and 14.
Platforms
The feature is supported on:
•
MGX 8850 (PXM45)
•
MGX 8850 (PXM1E)
•
MGX 8830
AXSM-16-155-XG
The AXSM-16-155-XG Service Module addresses the need for enhanced traffic management capabilities over a higher OC-3c/STM-1 port density. This card will provide a different option to customers currently using the AXSM/B and AXSM/E OC-3c/STM-1 modules.
This new AXSM-XG Service Module will support 124K connections and will provide a full 2.4 Gbps of usable bandwidth per card.
Platforms
This feature is supported on:
•
MGX 8850 (PXM45)
•
MGX 8950
AIS Delay, Deroute Delay, Absolute Grooming
AIS Delay: Sending AIS/Abit during grooming may cause customer to revert to backup facilities. The AIS Delay feature provides a mechanism to delay AIS/Abit up to a configurable time. This feature was supported in Release 4.0. The SNMP support for this feature is provided in Release 5.0.
Deroute Delay: This feature will allow some time for a failed NNI interface to recover at the physical layer, before the switch declares it as failed (due to LOS, LOF, AIS-P, and so forth). This feature was supported in Release 4.0. The SNMP support for this feature is provided in Release 5.0
Absolute Grooming This feature will allow grooming to use an absolute cost threshold in addition to percentage of threshold change. The feature was supported in 4.0. In this release, grooming thresholds have been enhanced to support AW, CTD, and CDV metrics on a per service category basis for both Percentage and Absolute Grooming Thresholds. The SNMP support for this feature is provided in Release 5.0.Platforms
This feature is supported on:
•
MGX 8850 (PXM45)
•
MGX 8950
•
MGX 8850 (PXM1E)
•
MGX 8830 (PXM1E)
Soft Reroute
Currently during grooming process the connection is derouted and rerouted when the connection is on a PNNI routed path. Even when the better/desired route is unavailable the connection shall be derouted and rerouted using PNNI. The soft reroute feature provides the user to move a routed SPVC/P from an incumbent working path to a new path with minimal loss of traffic. The existing connection along the path is not derouted until connection has been established on along a new path. Thus soft route brings higher connection availability. Enhanced grooming process shall use soft reroute to route a connection on better/desired PNNI path
QoS is preserved/improved by soft reroute for the rerouting connection.
Platforms
This feature is supported on:
•
MGX 8850 (PXM45)
•
MGX 8950
•
MGX 8850 (PXM1E)
•
MGX 8830 (PXM1E)
Point to Multipoint Support on PXM1E
MGX 8830 (PXM1E) and MGX 8850 (PXM1E) can be used in conjunction with an MGX (PXM45) in a network to support point-to-multipoint connections. The PXM45 hardware performs cell replication to multiple destination endpoints. The MGX with PXM1E functions as the originating node or as a via node of a point-to-multipoint connection. If necessary, MGX with PXM1E can be enabled to perform limited branching or cell replication to support multiple parties or leaves of a point-to-multipoint connection.
Point-to-multipoint connection is for applications such as data and video broadcasts and LAN emulation. This feature supports new real-time and non-real-time applications, for example: distance-learning, live broadcasts, conferencing applications, financial data delivery (stock market feeds), white board collaboration, video conferencing, data and file replication, and video on demand.
Network efficiency is enhanced since multiple streams of data can be replaced with a single transmission up to the multicast distribution point, typically a MGX with PXM45. Point-to-multipoint differs from broadcast in the sense that it will attempt to replicate packets only to specific destination endpoints in the multicast distribution tree versus sending packets to each endpoint as in straight broadcast.
Platforms
This feature is supported on:
•
MGX 8850 (PXM1E)
•
MGX 8830 (PXM1E)
Enhancements to Route Optimization
The feature enables the CWM to support scheduled/on-demand route optimization. The existing commands are also enhanced to support "Orderly Grooming" and allow users to schedule the route optimization based on "day(s) of the week". Trunk utilization factor is introduced to prevent connections from grooming to heavily loaded trunks.
The enhancements to route optimization enables customers to administer route optimization of connections from the Management station. The route optimization enhancements also include orderly grooming and trunk utilization factor for effectively managing the network.
Platforms
This feature is supported on:
•
MGX 8850 (PXM45)
•
MGX 8950
•
MGX 8850 (PXM1E)
•
MGX 8830 (PXM1E)
Priority Bumping
Priority Bumping involves derouting of other lower priority calls (lower than the incoming call priority) in order to free up resources so that the incoming higher priority call can be routed. Calls might have to be derouted on Ingress as well as Egress Interface to free up resources. Bumping can happen at Source, Via or destination nodes. This feature will work for SVCs as well as SPVCs. SVCs which do not have priority signalled from CPE/SAPI (in case of Voice Calls) will use the priority of the Ingress Interface.
Platform
This feature is supported on:
•
MGX 8850 (PXM45)
•
MGX 8950
•
MGX 8850 (PXM1E)
•
MGX 8830 (PXM1E)
Enhancements
The product enhancement requests (PERs) in Table 1 were introduced in Release 5.0.00.
Service Class Template (SCT) File Information
This section contains SCT file information for Release 5.0.00.
PXM1E
The Service Class Template (SCT) bundle in Release 5.0.00 includes updates:
•
PXM1E_SCT.PORT.5
•
PXM1E_SCT.PORT.6
The default SCTs provided with Release 5.0.00 are as follows:
•
SCT 5 - policing enabled. In general, this is for use on UNI ports.
•
SCT 6 - policing disabled. In general, this is for use on NNI ports.
The check sum for the SCT files are as follows
•
PXM1E_SCT.PORT.5.V1: Check sum is = 0xa287c4ee= 2726806766
•
PXM1E_SCT.PORT.6.V1: Check sum is = 0x79f6c93d= 2046216509

•
PXM1E_SCT.PORT.55.V1: Check sum is = 0x11a518f1= 296032497
Notes:
•
PXM1E does not support CARD SCT.
•
ABR VSVD parameters are not supported due to hardware limitation.
•
The above PXM1E SCT files apply to MGX 8850 (PXM1E) and MGX 8830
•
Use SCTs with larger vc thresholds configured for the VSI signalling service type. The maximum vc threshold value should be at least 50000 microseconds for the vsi signalling service type New SCTs 5,6 and 54, 55 (Cisco provided SCTs for the T3/E3, Combo cards and IMA group links respectively) have been released with minor version = 1. Custom SCTs need to upgrade to a new minor version if needed with the new recommended vc threshold values. It is possible to gracefully upgrade an SCT with minor version change without any traffic impact. Read the SCT config chapter of the configuration guide for more details on how to upgrade a SCT file to a new minor version.
