The PA-POS-2OC3 is a Cisco 7200 Series interface module providing two independent OC3c/STM1 Packet over SONET (POS) ports for high-speed WAN connectivity.
This adapter is compatible with Cisco 7200 Series routers equipped with an enhanced Multiservice Software feature set and an available network module slot.
Each port supports OC3c (155.52 Mbps) or STM1 (155.52 Mbps) full-duplex operation for Packet over SONET.
The PA-POS-2OC3 uses two SC-type single-mode fiber connectors per port, supporting ITU-T G.957 optical transceiver standards.
Yes, the adapter is fully hot-swappable, allowing front-panel insertion or removal without powering down the router.
It supports Frame Relay, HDLC, PPP, ATM, POS, IP, IPX, MPLS, and QoS features under Cisco IOS Software.
Power off the router, insert the adapter into an empty NM slot, tighten the captive screws, then power on and verify with the show diag command.
You need a Cisco Advanced IP Services or Enterprise Services license with Packet over SONET feature enabled on the 7200 Series router.
Under global configuration mode, define the POS interface (e.g., interface POS1/0), assign IP addressing, encapsulation pos, and any necessary MLM or QoS commands.
Each port delivers up to 155.52 Mbps full duplex, yielding an aggregate throughput of 311.04 Mbps.
The adapter operates between 0 °C and 45 °C ambient temperature and supports relative humidity from 10% to 90%, non-condensing.
The PA-POS-2OC3 consumes approximately 15 W of power during normal operation.
It’s ideal for high-speed WAN links, enterprise backbones, campus interconnects, and metro ring deployments requiring POS transport.
Use Cisco IOS commands show controllers pos, show interfaces pos, and show platform hardware slot to view status, counters, and optics information.
The Cisco spare part number for the PA-POS-2OC3 is 800-18502-01.
This adapter remains supported under Cisco’s Technical Assistance Center but is superseded by higher-speed POS modules for modern platforms.
