The WIC-2T is a Cisco 2-port serial WAN interface card. Both ports use the Cisco Smart Serial connector. Each port works asynchronously at up to 115.2 kbps, with a minimum of 600 bps, and for speeds below 600 bps the AUX port is used instead. Synchronous operation reaches 2.048 Mbps per port.
Higher synchronous speeds apply in some hosts. In NM-1FE1R2W, NM-1FE2W, NM-2FE2W and NM-2W network modules, or in Cisco 2600 chassis WIC slots, one port can run at 8 Mbps or two ports at 4 Mbps each, and every other WIC port on that module or chassis must stay unused. On Cisco 2691, 3725 and 3745 routers there is no restriction: all ports run at 8 Mbps together, up to six ports at 8 Mbps each.
Some hosts cannot use the card. The Cisco 1600 Series lacks the serial communications controllers it needs, and the NM-1E2W, NM-1E1R2W and NM-2E2W network modules lack the performance for it.
The WIC-2A/S also has two Smart Serial ports, and its only difference from the WIC-2T is a lower maximum synchronous speed of 128 kbps. Other WAN cards are sorted into the Cisco interface card category.
