2-Port Channelized T3/E3 ATM CEoP SPA Interface Specifications
The framer processes the incoming and outgoing T3 (C-Bit, m13/m23, and unframe) and E3 (g751) frames.
The framer operates at T3 or E3 line rates (44.736 or 34.368 Mbps), depending on the mode in which it is
configured.
The T3 or E3 data is encapsulated and sent across the MPLS network over user-configurable pseudowires.
In the ATM, the data is encapsulated into ATM cells and transported across the network
The T3/E3 SPA 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.
