In general terms, voice network modules convert telephone voice signals into a form that can be transmitted over an IP network. These modules have one or two slots for installing supported interface cards. Voice interface cards (VICs) or voice/WAN interface cards (VWICs) installed in the voice network module provide physical connections to the telephony equipment or network, and are connected using the appropriate cables.
