Two high-density 4-port connectors give the HWIC-8A/S-232, a Cisco 8-port asynchronous/synchronous WAN interface card, its eight low-speed ports. EIA-232 is the only serial standard, and each connector supports four ports as data communications equipment (DCE) or data terminal equipment (DTE) interfaces. All four ports on one cable use the same DTE or DCE mode.
Each port runs synchronous at up to 256 kbps or asynchronous at up to 230.4 kbps, with Bisync, lead manipulation and network clock synchronization. The cables are the CAB-HD4-232FC (4-port EIA-232 DCE, DB-25 socket) and the CAB-HD4-232MT (4-port EIA-232 DTE, DB-25 plug), each 10 ft (3 m).
SNA/SDLC, Bisync and X.25 traffic can be transported across an IP network over the synchronous ports, while the asynchronous ports handle console server and dial access work. The card fits the HWIC and EHWIC slots of Cisco 1841, 1941, 2800, 2900, 3800 and 3900 Series routers.
Eight asynchronous-only ports are on the HWIC-8A, and the HWIC-16A 16-port asynchronous card has sixteen. More serial and async cards for these routers are in Cisco interface cards.
