Cisco AS5350XM Universal Gateway CT3 Trunk Feature Cards
When provisioned as a CT3 trunk, the CT3 interface cards provide physical termination for CAS, PRI, or IMT trunks, and include CSUs that connect directly to the telco network (Figure 5). The CT3 interface card provides physical-line termination for a CT3 ingress trunk line. It uses an onboard multiplexer to multiplex 28 CT1 lines into a single CT3 line. Nonintrusive monitoring of individual T1/E1 signals is available at the front of the T1/E1 termination card with standard 100-ohm bantam jacks.
