The VIC2-4FXO is a Cisco 4-port FXO voice interface card (VIC) for analog voice and fax. It is a universal card for all countries: the ports are software-configured to work in any country, and every port can also be set as an analog CAMA port.
The FXO ports connect to a PBX or key system, or provide off-premise connections to the PSTN or PTT. They support battery reversal detection and caller ID. On the CAMA setting, the card connects to analog CAMA trunks that provide dedicated E-911 service in North America, and each port is configured individually as FXO or CAMA from Cisco IOS Software.
The EHWIC slots on Cisco 2900 Series routers support VICs natively, and the VIC2-4FXO also goes into the VIC/VWIC slot of the NM-HDV2, NM-HDV2-1T1/E1 and NM-HDV2-2T1/E1 network modules, where one VIC is the maximum per module. For Cisco 4000 Series ISRs, the four-port FXO function comes as the NIM-4FXO network interface module, and Cisco lists the VIC2-4FXO as its ISR G2 comparison.
Those ISR 4000 network modules are not supported in Cisco 2900 and 3900 Series routers, and on those ISR G2 routers the four-port FXO card is the VIC2-4FXO. Its ISR 4000 counterpart is the NIM-4FXO 4-port FXO network interface module, and the host routers include the CISCO2911/K9 Cisco 2911 router. More cards are in Cisco interface cards.
