3Com DSA-3CV1100-02 Figure 1 MTU/MDU Application

12 OVERVIEW
Figure 1 MTU/MDU Application
The VCN AC is connected to the VCN APs, the analog PBX, and an
Ethernet switch, e.g. a 3Com VCN Services Switch or a SuperStack II
Switch 1100. A standard metallic pair telephone line connects each VCN
AP to a VCN AC co-located with the analog PBX or local telephone
exchange.
The Visitor and Community Network solution also works with the
SuperStack II Switch 3300.
When a personal computer equipped with an Ethernet card is plugged
into the Ethernet port of the VCN AP, the Visitor and Comm unity
Network system provides fast internet and other network services for
data transmissions, and allows voice channels to be used simultaneously.
