Product Overview
The Cisco MGX
® 8800/8900 Series Switches provide the industry's most scalable family of multiservice switches, scaling from 1.2 Gbps to 180 Gbps redundant switching capacity and from DS0 to OC-192/STM-64 interface capacity. This scalability provides exceptional savings and efficiency for network operations and services growth. The Cisco
® MGX 8800 Series includes the Cisco MGX 8880 Media Gateway and the Cisco MGX 8830/B, MGX8850, MGX 8850/B, and MGX 8950 Multiservice Switches.
The Cisco 8-Port OC-12/STM-4 Channelized/Unchannelized ATM Switch Service Module is a line card for use in the Cisco MGX 8800/8900 Series multiservice Cisco MGX Switches in combination with the Cisco MGX 8800/8900 PXM-45 Processor Switch Module and the Cisco MGX 8950 XM-60 Switching Module (the latter for use on the Cisco MGX 8950 only). This ATM switch service module has 8 physical 622-Mbps interfaces that can be used to deliver high-density OC-12 or STM-4 trunking and User-Network Interface (UNI) or aggregation of sub-OC-12 traffic through port channelization.
Up to 12 Cisco 8-port OC-12/STM-4 ATM Switch Service Modules can reside in the Cisco MGX 8850, MGX 8850/B, MGX 8880, or MGX 8950 to provide support for up to 96 OC-12c/STM-4 interfaces for service providers that require both high bandwidth and high network availability. In the smaller Cisco MGX 8830/B chassis, up to 4 such service modules can be configured.
The Cisco 8-Port OC-12/STM-4 Channelized/Unchannelized ATM Switch Service Module meets service providers' demand for carrier-class availability by offering hot-standby 1+1 card redundancy as well as port redundancy with SONET/SDH automatic protection switching (APS). (See Figure 1.)
Note: The Cisco MGX 8800/8900 8-Port OC-12/STM-4 Channelized/Unchannelized ATM Service Module marginally exceeds jitter generation as specified by Telcordia GR-253 when tested in loop timing mode (that is, when the TX (Transmit) of a specific port redistributes its own line-recovered clock to other systems). However, jitter generation for the remaining ports is well within the limits specified by the GR-253 standard. Empirical testing has shown that the marginally higher jitter generation in loop timing mode should have no effect on the functional performance of the Cisco MGX 8800/8900 8-Port OC-12/STM-4 Channelized/Unchannelized ATM Service Module
