Cisco WIC-1ADSL-I-DG

The Cisco WIC-1ADSL-I-DG is a Wide Area Network Interface Card (WIC) module designed for Cisco routers. It is specifically used for connecting to Asymmetric Digital Subscriber Line (ADSL) networks. The "I-DG" in the model name stands for "Interleaved-Dynamic Gain," which refers to the specific type of ADSL technology supported by this module. The WIC-1ADSL-I-DG allows Cisco routers to establish a connection to an ADSL service provider, enabling high-speed internet access over existing telephone lines. It supports ADSL standards such as ANSI T1.413 Issue 2, ITU G.992.1 (G.DMT), and ITU G.992.2 (G.Lite). This module provides a single ADSL port and can be installed in a compatible Cisco router's WIC slot. It offers features like dynamic rate adaptation, error correction, and noise reduction to optimize the ADSL connection's performance and stability.
