Chapter 1 Introducing the MGX 8230

Summary of MGX 8230 Cards and Modules

Circuit Emulation Service Modules (CESM)

•Circuit Emulation Service Module for T1 (AX-CESM-8T1)

The AX-CESM-8T1 provides interfaces for up to eight T1 lines, each of which is a 1.544 Mbps structured or unstructured synchronous data stream.

•Circuit Emulation Service Module for E1 (AX-CESM-8E1)

The AX-CESM-8E1 provides interfaces for up to eight E1 lines, each of which is a 2.048-Mbps structured or unstructured synchronous data stream.

•Circuit Emulation Service Module for T3 and E3 (MGX-CESM-T3/E3)

The MGX-CESM-T3E3 provides direct connectivity to one T3 or E3 line for full-duplex communications at the DS3 rate of 44.736 MHz or at the E3 rate of 34.368 MHz. Each T3 or E3 line consists of a pair of 75-ohm BNC coaxial connectors, one for transmit data and one for receive data, along with three LED indicators for line status.

Voice Service Modules (VISM)

•MGX-VISM-8T1 and MGX-VISM-8E1

These cards support eight T1 or E1ports for transporting digitized voice signals across a packet network. The VISM provides toll-quality voice, fax and modem transmission and efficient utilization of wide-area bandwidth through industry standard implementations of echo cancellation, voice-compression and silence- suppression techniques.

Note For configuration information on the Voice Interworking Service Module (VISM), see the Voice Interworking Service Module Installation and Configuration Guide

Route Processor Module (RPM)

•Route Processor Module (RPM)

The RPM is a Cisco 7200 series router redesigned as a double-height card. Each RPM uses two single-height back cards. The back card types are single-port Fast Ethernet, four-port Ethernet, and single-port (FDDI).

Note For information on availability and support of the MGX-RPM-128/B and MGX-RPM-PR, see the Release Notes for “Cisco WAN MGX 8850, 8230, and 8250 Software”
