Cisco Products Supported by the NMT

New functionality is added in each release of the NMT to accurately reflect the current capabilities of the following Cisco equipment:

MGX 8850, MGX 8830, and MGX 8950 switches—Enables a wide range of user services to be supported by the BPX service node. Interfaces supported by the NMT include the following:

Frame Relay

ATM User-Network Interface (UNI)

Circuit emulation

n x T1/E1 inverse multiplexing for ATM (IMATM AUSM-8) UNI

3T3 interface using the SRM-3T3 module

MGX 8220, MGX 8230, and MGX 8250 edge concentrators—MGX Edge concentrators enable a wide range of user services to be supported by the BPX service node. Interfaces supported by the NMT include the following:

Frame Relay

ATM User-to-Network Interface (UNI)

Circuit emulation

n x T1/E1 inverse multiplexing for ATM (IMATM AUSM-8) UNI

3T3 interface using the SRM-3T3 module

BPX switch—A standards based high-capacity (9.6 Gb) broadband ATM switch that provides backbone ATM switching and delivers a wide range of user services. Fully integrated with the IPX and IGX switches, the BPX switch provides broadband ATM services when ASI and BXM cards are used. It also provides a variety of narrowband services; these services are provided by tiered network configurations that use IPX switches and MGX 8220 feeders.

The BPX switch supports the high density Broadband Switch Module (BXM) cards that provide standard interfaces for connecting to cell-based equipment by way of the ATM User-Network Interface (UNI).

BXM DS3/E3 supports E3/DS3 native ATM access and trunk ports.

BXM 155 supports OC-3/STM-1 native ATM access and trunk ports.

BXM 622 supports OC-12/STM-4 native ATM access and trunk ports.

BXM cards also support ATM Frame Relay networks and services and enables configuration of permanent virtual circuits (PVCs) or switched virtual circuits (SVCs) for the following defined service classes:

Constant bit rate (CBR)

Variable bit rate (VBR)

Unspecified bit rate (UBR)

Available bit rate (ABR)

SES PNNI Controller—Attaches to a BPX switch to provide Private Network-to-Network Interface (PNNI) signaling and routing for the establishment of ATM switched virtual circuits (SVCs) and soft permanent virtual circuits (SPVCs) over a BPX 8600 wide area network (WAN). Features supported by the NMT include PNNI Routing, resource partitioning, and shelf provisioning.
