SoundStructure TEL2
The SoundStructure TEL2 has a
LINE1
and a
LINE2
interface that can both be connected directly to two
analog telephone lines that comes from the local PBX or directly from the telephone central office as shown
in the following figure.
Note that the TEL2 interface does not support an optional handset - both telephone connectors on the rear
of the TEL2 are to be connected to analog telephone lines.
Using The TEL1 and TEL2
The SoundStructure TEL1 and TEL2 cards are configured through the SoundStructure Studio software as
described in the
Design Guide for the Polycom SoundStructure
manual.
The country setting of the telephone interface must be set prior to first use of the telephone line. The country
code may be set by clicking on the phone settings button for the channel that represents the telephone input.
This will show a user control, as shown in the figure below, that allows the selection of the country code for
the desired region.
The line voltage and loop current are always active and allow for diagnostics of the telephone line. See the
SoundStructure Command Reference Guide
for more information on how to query the line voltage and loop
current values.
Once the country code is set, the phone line may be tested by clicking the phone icon. This will take the
selected phone line off-hook. Assuming the signal routing is correct through the matrix, and the phone line
is plugged in and active, dial tone will be heard in the local room.
