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)

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.
