The Cisco T1/E1 circuit emulation service modules (CESMs) are designed for use with the MGX 8230, MGX 8250 series wide-area edge switches. The CESM-8T1 and CESM-8E1 offer eight T1s or E1s for structured and unstructured circuit services over an ATM backbone for the new world of data networking.The CESM provides constant-bit-rate (CBR) services over an ATM network. It allows circuit-based equipment, such as PBXs, to be interconnected over an ATM backbone via CBR connections. The current CESM-8 supports both ..
Cisco MGX 8800 Series Multiservice Switches provide the industry’s most scalable family of multiservice switches, scaling from 1.2 Gbps to 180 Gbps switching capacity and from DS0 to OC-192/STM-64 interface capacity. This family scalability provides exceptional savings and efficiency for network operations and services growth. The MGX 8800 family includes MGX 8000 Series Edge Concentrators and MGX 8800 Multiservice Switches...
The FRSM-8T1-C allows full DS0 and nxDS0 channelization of the T1s and E1s, for a maximum of 192 ports per FRSM-8T1-C. Using the FRSM-8T1-C, up to 192 fully channelized T1 lines can be operated simultaneously on the Cisco MGX platform...
This Cisco 8-port T1 Frame Service Module FRSM offers high-density native T1 frame service interfaces for the new world of data networking. This module offers eight ports of fractional/clear T1 frame services on a single, seven-inch function module. It provides interfaces for up to eight fractional T1 lines, each of which can support one 56 kbps or one Nx64 kbps FR-UNI, FR-NNI port, ATM-FUNI, or a Frame forwarding port. The module supports fractional and un-channelized T1 port selection on a per-T1 basis...
The MGX-FRSM-HS2 is the Frame Relay module with two HSSI ports.
