Модуль расширения Cisco Systems WIC-1DSU-56K4 1-Port 4-Wire 56Kbps DSU/CSU WAN Interface Card

Описание

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.

Platform Support

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.

Configuration

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.
