Cisco OSM-12CT3/T1

Cisco 7600 Series 12-Port Channelized T3 (CT3) to DS0 Optical Services Modules (OSMs) for channelized services enable the rapid, efficient addition of circuits within existing electrical connections. When a channelized circuit is established, all channels from DS3 to DS0 can be remotely provisioned, eliminating the need for the multiplexer line-card installations that are normally required to increase the available number of electrical circuits.
