This module supports voice, data, and integrated voice/data applications. For data applications, the VWIC provides a two-port WC for E1/FE1 with an integrated DSU. For a packet voice solution, the VWIC provides a dual-port voice interface card (VIC) with integrated DSU, that combines with the digital T1/E1 packet voice trunk modules. For multiplexed voice and data applications, this module provides a two-port VWIC E1/FE1 drop and insert multiplexer.
