Cisco Cisco MGX 8880 Media Gateway

The AXSM-8-622-XG Service Module is supported on the MGX 8880 in Release 5.3.00. 

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 Media Gateway in combination with the Cisco PXM-45 Processor 
Switch Module . This ATM switch service module has eight physical 622 Mbps interfaces that can be 
used to deliver high-density OC-12 or STM-4 trunking/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  MGX 8880 to 
provide support for up to 96 OC-12c/STM-4 interfaces for service providers that require both high 
bandwidth and high network availability.

The AXSM-8-622-XG service module is used in conjunction with the SFP-4-622 back card. This card 
is a 4-port SFP back card for OC-12/STM-4 interfaces.
