8-Port Channelized T1/E1 SPA Overview

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.

2-Port and 4-Port Clear Channel T3/E3 SPA Cables and Connectors

The interface connectors on the 2-Port and 4-Port Clear Channel T3/E3 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 and 4-Port Clear Channel T3/E3 SPA. The cables have
BNC on one end and the Siemax connectors on the other.
