The PCOU also provides ring detection, dial outpulsing, and hold circuitry. Each PCOU line
can be programmed for DTMF or dial pulse signalling.
Note
Toshiba strongly recommend that dial pulse signalling is not selected.

Excessive loudness which is caused by close proximity to a local Exchange or PBX can be
fixed through the PCOU decibel (dB) PAD switches. PCOU dB switches SW101, SW201,
SW301, and SW401 provide a -3 dB signal level drop between the PBX and local Exchange
when set to position 3. Switches are factory-set at the 0 (0 dB signal level drop) position.
See
Figure 3-10
and
Table 3-6
1.
If the Strata CT system is within one mile of the PBX or local Exchange, set the PCOU
dB PAD switches SW101, SW201, SW301, and SW401 to the 3 (-3 dB signal level
drop) position.
2.
Insert the PCOU (component side facing right) into the appropriate slot, and apply firm,
even pressure to ensure proper mating of connectors.
3.
After installing the PCOU, gently pull the PCB outward. If the connectors are properly
mated, a slight resistance will be felt.
