North American robbed-bit signaling (RBS) is supported on T1 trunks, including a variety of North
American RBS protocol, framing, and encoding types on these trunks.
CAS is supported for E1 trunks, with R2 signaling.
Many countries require an E1 R2 variant. Per-country defaults are provided for supervisory and
inter-register signaling.
The CT3 DFC provides physical line termination for a channelized T3 ingress trunk line, and it uses
an onboard multiplexer to multiplex 28 channelized T1 lines into a single channelized T3 line.
Universal access (analog modem or digital calls) is supported when an interface is configured for
ISDN PRI signaling. PRI signaling is available for both T1 and E1 trunks.
