Each DFC is a 5.1 by 13 inch PCI-based interface board. The following is a brief description of the trunk
types supported:
•
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.
