Cisco Mobile Wireless Transport Manager Release 5.0.1

The Cisco Mobile Wireless Transport Manager (MWTM) is a network management software product that network administrators use to discover, manage, and troubleshoot networks that include Cisco Radio Access Network Optimization (RAN-O) devices, such as the Cisco Mobile Wireless Router (MWR).
In Release 5.0.1, MWTM provides bug fixes ("Resolved Caveats" section) and new features ("What's New in MWTM R5.0.1" section).

What's New in MWTM R5.0.1

Support for MWR mini-aggregation node for Global System for Mobile (GSM)
The initial configuration that the MWTM supports included two MWRs, one at the cell site, and one at the Base Station Controller (BSC) or Radio Network Controller (RNC) site. These MWRs were connected back to back over a Multilink Point-to-point (MLPPP) backhaul connection to support GSM and Universal Mobile Telecommunications System (UMTS) communications.

Support is now added for aggregating the backhaul connections from two cell-site MWRs to one MWR (called the mini-aggregation node) at the BSC site. The MWTM supports this GSM-only configuration and accurately reports on link statistics.

Support for fractional T1/E1 on shorthaul and backhaul
The MWTM provides support for fractional T1/E1 services through the allocation of time slots on shorthaul and backhaul connections.

Support for UMTS-only configuration
The UMTS-only configuration accommodates only UMTS traffic (no GSM traffic). The RAN-O device receives the UMTS traffic over Asynchronous Transfer Mode (ATM) Private Virtual Channels (PVCs) and carries that traffic over the MLPPP backhaul connection.

Support for configurations that use:
•PVC routing
•High-speed Downlink Packet Access (HSDPA)
•Inverse Multiplexing over ATM (IMA)
The PVC routing configuration uses the MLPPP backhaul to carry GSM and UMTS traffic and a second backhaul over the Fast Ethernet (FE) interface to carry only UMTS traffic. PVC routing refers to PVCs on a single UMTS interface that are split between the two backhaul interfaces.

A second variation of the PVC topology uses HSDPA. In this UMTS-only topology, the traffic flows between the RAN-O devices over the FE backhaul connection while using the serial interface (MLPPP backhaul) only for line clocking. This topology is for those vendors who want to run only UMTS traffic in their networks.

A third variation of the PVC topology uses IMA to aggregate shorthaul ATM interfaces into a logical group or bundle. This topology is for those vendors who want to provide redundancy and load balancing for shorthaul UMTS traffic. The IMA technology can be deployed in UMTS-only or mixed GSM and UMTS configurations.

The MWTM accurately reports statistics for PVCs that are routed over the MLPPP backhaul or the FE backhaul connections.

Graphical User Interface (GUI) enhancements
Shorthaul Performance and Backhaul Performance tabs moved from the Node Details Window to the Interface Details Window. To view real-time utilization statistics for an interface, left-click the interface under a node in the MWTM tree (left pane) of the main window. Then click the appropriate tab for the statistics that you want to view.
