The 1-port 4-wire 56/64 kpbs Channel Service Unit/Data Service Unit (CSU/DSU) WAN interface card (WIC) (WIC-1DSU-56K4) is combined within a single WIC and performs the CSU/DSU functions for both DDS (dedicated) and 4-wire switched 56 kbps data networks. It also provides an all rate synchronous interface to any dedicated Digital Data Service (DDS) point-to-point or multi-point network compatible with AT&T Publication 62310. The WIC-1DSU-56K4 also supports 4-wire switched 56 data services such as AT&T's Accunet 56 or Sprint's VPN-56 plus many switched data services offered by local exchange carriers.

WIC-1DSU-56K4 - One Port Four Wire 56/64 Kbps CSU/DSU WAN Interface Card
This list details the features associated with the WIC-1DSU-56K4:
Implements the switched 56 k and DDS (leased line) operation.
Identical hardware feature set to the 4-wire 56/64 k CSU/DSU for the 2524-2525.
Identical Cisco IOS® software configuration.
Supports the DDS (leased line) operation (AT&T Pub. 62310).
Supports DDS loop rates 2.4, 4.8, 9.6, 19.2, 38.4, 56, and 64 kbps.
Supports the switched 56 operation at 56 kbps (AT&T Pub. 41458, Sprint TS-0046).
Receiver sensitivity is -45db at all loop rates.
Uses the Self Test Function (at power on and user initiated) and Network line and data terminal equipment (DTE) loopbacks. User initiated DTE, line, and remote V.54 loopbacks diagnostic functions.
Compliant with UL 1950, UL 1459, CSA 22.2-950, CSA 22.2-255, FCC part 15J Class A, and FCC part 68.

Note: The Cisco IOS software releases provided are typically the minimum version required to support the platform, module, or feature in question. Use the Software Advisor (registered customers only) to choose appropriate software for your network device: match software features to Cisco IOS and CatOS releases, compare IOS releases, or find out which software releases support your hardware.
The WIC-1DSU-56K4 interface card uses service-module commands. Below is a sample configuration.
Note: There are no framing or linecode commands. This is because the 56 k card is not a T1 and does not relate to timeslots. There are 24 timeslots in a T1: 24 x 64 DS0s=1.544m
This card is strictly 56 k and timeslots are not relevant.

For a list of commands available, refer to Configuring Cisco Integrated Data Service Unit/Channel Service Unit (DSU/CSU) Modules and WAN Interface Cards.
To perform a loopback test refer to Loopback Tests for T1/56 K Lines.
The WIC-1DSU-56K4 module uses a standard straight through RJ-45 cable to connect from the RJ-48S jack on the CSU/DSU to the wall jack.
