The SPA-4XOC3-ATM is the Cisco 4-port OC-3c/STM-1c ATM shared port adapter, the four-port member of a group with a 2-port OC-3c and a 1-port OC-12c/STM-4c model. It fits SPA interface processors in Cisco 7600 Series routers and Catalyst 6500 Series switches.
Maximum power is 24.8 W without optics. The adapter is hot-swappable with service-transparent online insertion and removal, each port takes a replaceable SFP optic, and 1+1 SONET APS and SDH MSP protection are supported. Timing is either local (internal) for dark fiber or WDM links, or loop (line) timing for connection to SONET/SDH equipment.
SONET monitoring covers loss of signal, loss of frame, line and path alarm indication, remote defect and remote error indication, B1, B2 and B3 error counts, and threshold crossing alarms on B1 and B2. The adapter has a single software reset and uses the RFC 2558 SONET/SDH MIB with SNMP management.
The 1-port OC-12c/STM-4c model is the SPA-1XOC12-ATM, and the 2-port OC-3c model is the SPA-2XOC3-ATM. More adapters are in Cisco interface cards.
