The SPA-2XOC3-POS is a Cisco 2-port OC-3c/STM-1c packet over SONET/SDH (POS) shared port adapter, and each port takes an SFP optic. Encapsulations are HDLC (RFC 2615), PPP (RFC 1662) and Frame Relay (RFC 2427) with IPv4 and IPv6, and POS payload mapping uses a 1 + x^43 self-synchronous scrambler.
Timing is local (internal) or loop timed from the network, with local diagnostic and line loopback. Alarm and event reporting spans the section, line and path levels, including loss of signal, loss of frame and path alarm indication signal. 1+1 SONET automatic protection switching, SDH linear multiplex-section protection, online insertion and removal and the RFC 2558 SONET/SDH MIB are all supported.
The adapter weighs 0.75 lb (0.34 kg), is a single-height card at 0.8 x 6.75 x 7.28 in., and uses 13 W maximum without optics. It goes in the Cisco 7304 router, Catalyst 6500 Series switches, Cisco 7600 Series routers and Cisco ASR 1000 Series routers. The 4-port model is the SPA-4XOC3-POS. For 40 km reach, add the SFP-OC3-LR1 optic; more WAN adapters are in Cisco interface cards.
