Programming a circuit
To program a circuit, select the appropriate programmable feature key and press # to confirm. If programming
with a 48-Key Feature Phone, you can select one or all of the channels on the first T1/PRI Module;
otherwise, only the first 12 T1 channels will appear initially, and you must use the scroll keys to program
T1 channels 13–24. If multiple T1/PRI Modules are installed, use the scroll keys to select channels from
the additional T1/PRI Modules.

After selecting the COs to program, use the scroll keys to select the new level of gain or loss in db. Press #
to confirm. Select additional circuits to adjust and program as above.
RECEIVE VOLUME
LINE COMP -20DB>
Range: -22 db to 12 db (lowest to highest gain, respectively). Default: 0 db.
Function 234: PRI line receive volume
Many variables can affect the volume of PRI lines. Different volume levels may be required when connecting
a T1/PRI Module, depending on the signal level of the PRI line. The volume level can be adjusted by
increasing or decreasing the setting in this function. By default, the setting is 0 dB; changes to the setting are
in 2-dB increments.
Example: If calls received at the extension have low volume levels, you can adjust that PRI circuit’s pad level to
increase the volume. Select the circuit to adjust by pressing the appropriate programmable feature key
and press # to confirm. Use the scroll keys to select the appropriate dB level and press # to confirm.
