Connection Considerations

This section discusses the special connection consideration for various environments and

situations where you can use the VoIP Gateway.

6.1Port Configuration

VoIP Gateway supports FXS and FXO ports.

FXS (Foreign Exchange Station)

FXS provides power and ringing signals to its interfacing equipment. It is not intended for connection to the Public Switched Telephone Network. It is a station loop start operation that provides a connection to:

1.A standard, single-line analog telephone system

2.The line circuit of a key telephone system

3.A loop start trunk circuit of a Private Branch Exchange (PBX) that normally connects to incoming Central Office circuits

FXO (Foreign Exchange Office)

FXO recognizes signals and draws current to indicate an active state. It is a trunk loop start operation that emulates a single-line telephone to:

1.Central Office lines

2.PBX station

There are two basic environments that the TVP-221H can be applied to. They are described in the following sections.
