Feature Cards
Each feature card is a 5.1- by 13-inch (13- by 30-cm) PCI-based interface board.
The following trunk types are supported:
•T1 feature card—Supports North American robbed-bit signaling (RBS) on T1 trunks, including a variety of North American RBS protocol, framing, and encoding types.
•E1 feature card—Supports channel-associated signaling (CAS) for E1 trunks, with R2 signaling. Many countries require an E1 R2 variant. Per-country defaults are provided for supervisory and inter-register signaling.
•Channelized T3 (CT3) feature card—Provides physical line termination for a channelized T3 ingress trunk line, and uses an onboard multiplexer to multiplex 28 channelized T1 lines into a single channelized T3 line.
