The dual-serial port WAN interface cards (WICs) for the Cisco 2600 and 1700 series feature Cisco`s new, compact, high-density Smart Serial connector to support a wide variety of electrical interfaces when used with the appropriate transition cable. Two cables are required to support the two ports on the WIC. Each port on a WIC is a different physical interface and can support different protocols such as Point-to-Point protocol (PPP) or Frame Relay and Data Terminal Equipment/Data Communications Equipment (DTE/DCE).

|WIC-2T||2 Port Serial WAN Interface Card|
The WIC-2T provides two serial ports using the Smart Serial connector.
Asynchronous support with a maximum speed (per port) of 115.2 Kbps, minimum 600 bps. If you need to run at speeds lower than 600 bps, use the AUX port instead.
Synchronous support with a maximum speed of 8 Mbps per port.
Supports one port at 8 Mbps when used in NM-1FE1R2W, NM-1FE2W, NM-2FE2W, or NM-2W, or Cisco 2600 chassis WIC slots. All other WIC ports on that network module or Cisco 2600 chassis must not be used.
Supports two ports at 4 Mbps each when used in NM-1FE1R2W, NM-1FE2W, NM-2FE2W, or NM-2W, or Cisco 2600 chassis WIC slots. All other WIC ports on that network module or Cisco 2600 chassis must not be used.
Supports 8 Mbps on all ports simultaneously on 2691, 3725, and 3745. No restrictions. Maximum six ports at 8 Mbps each.
Note: The X.21 interface protocol is not recommended for clock rates beyond 4 MHz. For clock rates beyond 4 MHz, V.35 interface is recommended.
The WIC-2T serial ports require Smart Serial cables. The following table lists the part number for the cables that can be used with the WIC-2T card.

The Cisco 1600 Series is not capable of supporting the WIC-2T due to lack of Serial Communications Controllers.
The NM-1E2W, NM-1E1R2W, and NM-2E2W Network Modules do not have enough performance power to support the WIC-2T due to hardware limitations.
The show version command shows WIC-2T as "low-speed". This is a display only (cosmetic) problem.
The WIC-2T and WIC-2A/S can be damaged by excessive electrostatic discharge. You can minimize this electrostatic discharge in several ways.
Use shielded cable end-to-end.
Use a data surge protector that protects against surges over +/- 18v.
Use an optical isolator (best protection).
This is a sample configuration for the WIC-2T interface card.
Note: There are no framing, clocking or linecode parameters or commands being used here. This is because this card does not have an integrated channel service unit/data service unit (CSU/DSU). You need to use an external CSU/DSU.
