4-Port Channelized T3 to DS0 Interface Specifications
The framer processes incoming and outgoing T3 frames (cbit, m13/m23, and unframe). The framer operates
at T3 line rates (44.2 Mbps).
Packet data is transported with a user-configurable encapsulation (such as Point-to-Point Protocol [PPP] or
High-Level Data Link Control [HDLC]), and is mapped to T3 frames. The encapsulations add transport
overhead to the packet of data frames before transporting, and are stripped when a packet is transported to
the far end.
The 4-Port Channelized T3 to DS0 interface is compliant with ANSI and Telco standards. The interface also
provides support for Management Information Base (MIB) RFC 2495, RFC 2496, and T1.231.
