The WIC-2A/S is a Cisco 2-port asynchronous/synchronous serial WAN interface card, and its two serial ports use the Smart Serial connector. The only difference between the WIC-2A/S and the WIC-2T is the maximum supported sync speed.
Asynchronous operation runs from a minimum of 600 bps to a maximum of 115.2 kbps, and for speeds below 600 bps Cisco points to the AUX port instead. Synchronous operation tops out at 128 kbps.
Two limits apply. The Cisco 1600 Series cannot support the WIC-2A/S as it lacks the Serial Communications Controllers, and the NM-1E2W, NM-1E1R2W and NM-2E2W network modules do not have the performance to support it.
The card fits the modular Cisco 1800 Series, the Cisco 2800 Series, the Cisco 3800 Series, the Cisco ICS 7750 and the Cisco MWR 1941-DC. The Smart Serial cable it uses is also used with the HWIC-4A/S, HWIC-4T and WIC-2T. More cards are in Cisco interface cards and host routers are in Cisco routers.
