The SPA-4XT3/E3 is a Cisco 4-port clear channel T3/E3 serial shared port adapter (SPA). Its framer works at the T3 line rate of 44.736 Mbps or the E3 line rate of 34.368 Mbps, depending on how the port is configured. It handles T3 frames (C-bit, M13/M23 and unframed) and E3 frames (G.751, G.832 and unframed).
Packet data uses a user-configurable encapsulation such as Point-to-Point Protocol (PPP) or High-Level Data Link Control (HDLC). The interface supports MIB RFC 2496 and T1.231.
The connectors are 75-ohm coaxial Siemax types, one for transmit (TX) and one for receive (RX) on each port. The cables CAB-T3E3-RF-BNC-M (10 feet, male BNC) and CAB-T3E3-RF-BNC-F (10 feet, female BNC) have BNC connectors on one end and Siemax connectors on the other. Each port has two LEDs, C/A and A/L, and the adapter has one STATUS LED.
The SPA-4XT3/E3 is supported in the Cisco ASR 1000 Series router with the ASR1000-SIP10 SPA interface card, and it supports online insertion and removal independently of the SIP. The Cisco interface cards section holds more WAN adapters, and router hosts are under Cisco routers.
