SPA-4XOC12-POS Overview
SPA-4XOC12-POS Four-Port Packet-over-SONET Adapter
SPA-4XOC12-POS is a four-port OC-12/STM-4 Packet-over-SONET/SDH Shared Port Adapter. It is a carrier-interface module that requires a compatible router, SIP, software release and optical design; it is not a 10GbE Ethernet adapter and does not operate without a supported host.
Host and software qualification
Cisco lists the PID among supported SPAs for ASR 1006-X/1009-X. For ASR 9000 SIP deployments, Cisco's compatibility table identifies four OC-12 ports, single-height format, hardware revision 1.0 and IOS XR 4.3.0 as the original minimum; later ASR 9000 release notes document model support from IOS XR 6.4.2. Qualify the exact chassis/SIP/release combination in current Cisco records.
Optical and POS circuit acceptance
For each of four circuits, record SONET or SDH framing, SFP PID, wavelength, reach, received/transmit power, clocking, encapsulation and remote-end configuration. Clear LOS, LOF, AIS and RDI conditions, then verify payload, error counters, loopback behavior and protection design under sustained traffic.
Retirement planning
Cisco's ASR1001-X/ASR1002-X associated-SKU bulletin ended sale August 1, 2022 and lists July 31, 2027 as the last support date for this PID, with no replacement product. Preserve legacy-circuit requirements before considering Ethernet migration or a different transport platform.
