2-Port Channelized T3/E3 ATM CEoP SPA Overview Chapter 3 Overview: Cisco ASR 1000 Series Aggregation Services Routers SPAs 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. Note Effective from Cisco IOS XE Release 3.4.0S, the 2-Port Channelized T3/E3 ATM CEoP SPA supports only the ATM mode and not the CEM mode. It supports ATM only on the clear-channel T3 mode. Note Effective from Cisco IOS XE Release 3.5.0S, the SPA-2CHT3-CE-ATM supports ATM on the 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. 2-Port Channelized T3/E3 ATM CEoP SPA Cables and Connectors The interface connectors on the 2-Port Channelized T3/E3 ATM CEoP SPA are 75-ohm coaxial Siemax 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 Siemax connectors on the other end. If similar SPAs are connected back-to-back, both ends of the cable are Siemax. The cables specifications that can be used for the 2-Port Channelized T3/E3 ATM CEoP SPA are: • CAB-T3E3-RF-BNC-M (T3 or E3 Cable, 1.0/2.3 RF to BNC-Male, 10 feet) • CAB-T3E3-RF-BNC-F (T3 or E3 Cable, 1.0/2.3 RF to BNC-Female, 10 feet) • CAB-T3E3-RF-OPEN (T3 or E3 Cable, 1.0/2.3 RF to BNC-Open end, 10 feet) Note The Cisco cable part numbers are 72-4124-01 (for the male BNC end) and 72-4131-01 (for the female BNC end). A SPA can receive data over the cable up to a maximum distance of 1350 ft (411.5 meters). 3-78 Cisco ASR 1000 Series Aggregation Services Routers SIP and SPA Hardware Installation Guide OL-14126-12

Overview: Cisco ASR 1000 Series Aggregation Services Routers SPAs
2-Port Channelized T3/E3 ATM CEoP SPA Overview
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.
Note
Effective from Cisco IOS XE Release 3.4.0S, the 2-Port Channelized T3/E3 ATM CEoP SPA supports
only the ATM mode and not the CEM mode. It supports ATM only on the clear-channel T3 mode.
Note
Effective from Cisco IOS XE Release 3.5.0S, the SPA-2CHT3-CE-ATM supports ATM on the
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.
2-Port Channelized T3/E3 ATM CEoP SPA Cables and Connectors
The interface connectors on the 2-Port Channelized T3/E3 ATM CEoP SPA are 75-ohm coaxial Siemax
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 Siemax connectors on the other end. If similar SPAs are connected
back-to-back, both ends of the cable are Siemax.
The cables specifications that can be used for the 2-Port Channelized T3/E3 ATM CEoP SPA are:
CAB-T3E3-RF-BNC-M (T3 or E3 Cable, 1.0/2.3 RF to BNC-Male, 10 feet)
CAB-T3E3-RF-BNC-F (T3 or E3 Cable, 1.0/2.3 RF to BNC-Female, 10 feet)
CAB-T3E3-RF-OPEN (T3 or E3 Cable, 1.0/2.3 RF to BNC-Open end, 10 feet)
Note
The Cisco cable part numbers are 72-4124-01 (for the male BNC end) and 72-4131-01 (for the female
BNC end). A SPA can receive data over the cable up to a maximum distance of 1350 ft (411.5 meters).
