Introduction
The VG248 is a 19-inch rack-mountable hardware device. It includes 48 FXS port
interfaces to connect directly to standard analog telephones, modems, or fax
machines. The analog devices connected through the FXS port behave as if they
are connected to a normal central office (CO) or PBX line, supporting features
such as call waiting, caller ID, call transfer, and call transfer.
The VG248 also includes a 10/100 Mbps Ethernet port interface to connect to the
Ethernet network for connectivity to Cisco CallManager and the IP telephony
network.
