The Cisco® 1-Port OC-3/STM-1 and 3-Port T3/E3 Multiprotocol Service Modules (MPSM-T3E3-155) provide the capability to offer ATM and Frame Relay services in the same module. The MPSM-T3E3-155 module is available for both the Cisco MGX® 8850/B and MGX 8830/B Multiservice Switches, offering high port density using OC-3/STM-1 or T3/E3 interfaces; these interfaces can be channelized down to DS0/DS1/DS3 interfaces.
Product Overview
The Cisco 1-Port OC-3/STM-1 or 3-Port T3/E3 Multiprotocol Service Module (MPSM-T3E3-155) is a single-height service module for the Cisco MGX 8850/B and the Cisco MGX 8830/B Advanced ATM Multiservice Switches. The Cisco Multiprotocol Service Module delivers connectivity from DS-0 to OC-3 speeds and provides Any Service, Any Port (ASAP) capability. ASAP allows service providers to provision both Frame Relay and ATM services on any port in the service module, allowing for reduced capital and operating expenditures.
• Channelization down to DS-0 for Frame Relay and DS-1 for ATM service
• FRF 8.1 Frame Relay-to-ATM service interworking
• Inverse Multiplexing over ATM (IMA) 1.0 and IMA 1.1 along with IMA restart capability
• Private Network-Network Interface (PNNI) 1.0
• Standard available bit rate (ABR) with virtual source/virtual destination support
• Support for 1:1 front-card redundancy with Y-cable
• Support for 1:1 and 1+1 Automatic Protection Switching (APS) and clear-channel (DS-3/E3) port
• Support for mixed-mode channelization of T1 and E1 ports simultaneously
• Simultaneous support of T3 and E3, or T1 and E1
• Built-in bit-error-rate-test (BERT) testing at the channelized level
