ماژول Cisco PA-MC-STM-1
The Multichannel STM-1 (PA-MC-STM-1) on the Cisco 7600, FlexWAN module, and 7500 and 7200 Series routers provides the solution service providers and their customers need. It reduces network complexity and provisioning time and is part of the industry's most widely deployed and trusted network platforms today. It is also backed by a world-class customer support network.
The PA-MC-STM-1 enables service providers to use a single fiber-optic circuit to provision 63 E1s-E1s that normally require 63 separate copper pairs. The PA reduces wiring complexity, and, when spare capacity is available, it enables service providers to "turn up" new E1s without dispatching a technician to the router. For service providers with customers who require smaller circuits, the PA-MC-STM-1 supports as many as 256 channel groups and can provision circuits down to DS0-providing even more flexibility and density .
