The Cisco SPA-8XCHT1/E1 is an 8-port channelized T1/E1 to DS0 shared port adapter (SPA). Its eight ports use RJ-48c receptacles, and all of them can be used at the same time. On the E1 side the cables are 120-ohm shielded twisted pair with RJ-45 connectors, and the connections meet G.703.
The serial mode is chosen per adapter with the card type command, t1 at 1.536 Mbps or e1 at 2.048 Mbps unframed. T1 ports can be channelized down to DS0 at multiples of 56 kbps or 64 kbps, with D4 superframe and extended superframe support. Feature support includes PPP, HDLC and Frame Relay encapsulation, selectable internal or network clock per port, bit error rate testing, local and remote loopback, MLPPP and compressed RTP.
Each port has two LEDs, C/A for carrier and alarm and A/L for active and loopback, and one STATUS LED covers the adapter. On the Cisco ASR 1000 Series the SPA-8XCHT1/E1 is supported in the ASR1000-SIP10. The spare ordering number is SPA-8XCHT1/E1=. Channelized and serial SPAs are browsable under Cisco interface cards.
