DATA SHEET

The Cisco® MGX® 8800 Series 16-Port T1/E1 Multiprotocol Service Module (MPSM) is a 16-port T1 or E1, single-height service module for use in the Cisco MGX 8800 Series of multiservice switches. The MPSM delivers connectivity from DS0 to T1/E1 speeds and provides Any Service, Any Port (ASAP) capability.

Figure 1. Cisco MGX 8800 Series 16-Port T1/E1 MPSM (far left) with associated back cards: Cisco MGX 16-Port T1/E1 Backcard with RBBN Connector, Cisco MGX 16-Port T1/E1 Redundancy Backcard, and Cisco MGX 16-Port E1 Backcard with MCC Connector

ASAP allows customers to provision both Frame Relay and ATM services on a single MPSM. The MPSM also supports additional features as described in this data sheet.

KEY FEATURES

• ASAP functionality reduces operation and deployment costs because one MPSM card can act as both a Frame Relay and an ATM service module

• Built-in BERT testing

• IMA 1.0 and IMA 1.1 along with IMA Restart Capability

• Support for multiple ATM frame sizes from 32 to 256 bytes

• ITC and CTC clocking modes

• Support for FRF 8.1 Frame Relay/ATM service interworking

• Support for 1:N redundancy

• Support for Multilink Point-to-Point Protocol (MLPPP) and PPP multiplexing (PPPMUX)
