Official Full Name
Cisco 2-Port Generation 2 Foreign Exchange Office Voice Interface Card
Spare SKU:VIC2-2FXO=
Naming Breakdown
-
VIC2: Voice Interface Card, Generation 2
-
2: Two physical analog voice ports
-
FXO: Foreign Exchange Office analog trunk interface
Core Product Positioning
The Cisco VIC2-2FXO is a second-generation pluggable analog voice mezzanine daughterboard designed for Cisco multiservice integrated access routers. Unlike FXS ports, FXO trunk ports do not supply dial tone or battery power; they connect to external PSTN central office lines or analog trunk ports of legacy PBX systems. This module builds analog PSTN gateway connections for VoIP deployments, supporting toll bypass, Survivable Remote Site Telephony (SRST), Cisco Unified Communications Manager Express (CUCME), and hybrid TDM-IP telephony migration for branch offices.
