This chapter shows you the basic concept and steps to help
you configure your ITG through the LAN port. It includes the
VG-400R voice port and Dial Plan.
6.1 Concepts
6.1.1 The Voice Port
There are two types of voice port, FXO ( F oreign e X change
O ffice) and FXS ( F oreign e X change S tation). You should locate
them at the labels of the RJ-11 ports.
FXO port
The FXO port allows connecting to a device which is
associated with a phone number and which can generate a ring
signal; say 316, or 408-1234. So the only connection for FXO
port will be to your local PSTN Line or one of the analog
extension line associated with your PBX system.
When your FXO port
connects to a PSTN Line, the
VoIP call can be made to the
local number (408-1234). Or,
vise versa you may make a
VoIP call through the phone
number 408-1234.
The same is applied to a PBX system. You are required to know
which extension number will be assigned to the FXO port. Your
PBX users will need to know this number to make a VoIP call.
