The HWIC-2A/S is a Cisco 2-port asynchronous/synchronous serial WAN interface card for Cisco 1800, 1900, 2800, 2900, 3800 and 3900 Series integrated services routers. Both ports use Cisco Smart Serial connectors, and the card is a single-wide HWIC with no slot restrictions.
The speed limits differ from the HWIC-2T: a port runs synchronously at up to 128 kbps and asynchronously at up to 115.2 kbps, and Bisync is supported. Serial signaling covers EIA-232, EIA-449, EIA-530, EIA-530A, V.35 and X.21, with network clock synchronization. Common jobs for HWICs of this range are remote network management, external dial-modem access, low-density WAN aggregation and legacy protocol transport.
Ten-foot (3 m) Smart Serial cables for the card include CAB-SS-V35MT and CAB-SS-V35FC for V.35, CAB-SS-232MT and CAB-SS-232FC for EIA/TIA-232, CAB-SS-449MT and CAB-SS-449FC for EIA/TIA-449, and CAB-SS-X21MT and CAB-SS-X21FC for X.21. Routers that take the card are in Cisco routers, and to compare it with other router cards, open Cisco interface cards.
