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.

Effective from Cisco IOS XE Release 3.4.0S, the 2-Port Channelized T3/E3 ATM CEoP SPA supports

Note

only the ATM mode and not the CEM mode. It supports ATM only on the clear-channel T3 mode.

Effective from Cisco IOS XE Release 3.5.0S, the SPA-2CHT3-CE-ATM supports ATM on the

Note

clear-channel E3 mode.

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.

Note

Effective from Cisco IOS XE Release 3.6.0S, the SPA-2CHT3-CE-ATM supports the CEM mode.

The interface connectors on the 2-Port Channelized T3/E3 ATM CEoP SPA are 75-ohm coaxial DIN

1.0/2.3 types, with one connector and cable for transmit (TX) and one for receive (RX).

The following cables can be used with the 2-Port Channelized T3/E3 ATM CEoP SPA. The cables have

BNC connectors on one end and DIN 1.0/2.3 connectors on the other end. If similar SPAs are connected

back-to-back, both ends of the cable are DIN 1.0/2.3.

The cables specifications that can be used for the 2-Port Channelized T3/E3 ATM CEoP SPA are:

•

The Cisco cable part numbers are 72-4124-01 (for the male BNC end) and 72-4131-01 (for the female

Note

BNC end). A SPA can receive data over the cable up to a maximum distance of 1350 ft (411.5 meters).
