2-Port and 4-Port Clear Channel T3/E3 SPA Interface Specifications
The framer processes incoming and outgoing T3 (cbit, m13/m23, and unframe) and E3 (g751, g832, and
unframe) frames. The framer operates at T3/E3 line rates (44.736 Mbps/34.368 Mbps) depending on the
mode in which it is configured.
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 and E3 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 T3/E3 SPA interface is compliant with ANSI and Telco standards. The interface also provides
support for Management Information Base (MIB) RFC 2496 and T1.231.
