The SPA-2XCT3/DS0 is a Cisco 2-port channelized T3 serial shared port adapter (SPA) for Cisco ASR 1000 Series routers. It is compatible with the ASR1000-SIP10 SPA interface processor, and the 4-port model is the SPA-4XCT3/DS0.
Each port has a 75-ohm coaxial Siemax connector pair, one for transmit (TX) and one for receive (RX), and RG-59 coaxial cable attaches to each. The cables have BNC on one end: CAB-T3E3-RF-BNC-M and CAB-T3E3-RF-BNC-F, each 10 feet, or CAB-T3E3-RF-OPEN with an open BNC end.
The framer works on cbit, m13/m23 and unframed T3 frames at the T3 line rate of 44.2 Mbps. Packet data travels in a user-configurable encapsulation such as PPP or HDLC, and the interface is compliant with ANSI and Telco standards, with MIB support for RFC 2495, RFC 2496 and T1.231.
Every port has a C/A LED and an A/L LED, and the SPA has one STATUS LED that turns green when the SPA is ready and operational. The SPA supports online insertion and removal independently of the SIP, and an empty subslot needs a blank filler plate. Further interface modules are in Cisco interface cards.
