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).

versions.
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.
