Circuits per PCB:
four DID line circuits
Interfaces with:
DID lines
Older Version(s):
none
The optional TDDU PCB installs onto the TMAU motherboard. (See
and
for information on controls, indicators and connectors and
for wiring.)
Note
Only one TCOU or TDDU can be installed on the motherboard.
TDDU Installation
1. Make sure the power supply (TPSU16A) DC power switch is Off.
2. Mate the TDDU male connectors P110, P111, P112 to the TMAU female connectors. Apply
firm, even pressure to ensure proper connection. (See
for installation
and
for wiring.)
3. Secure the three plastic stand-off tabs and install screws in the upper right and lower left
corners.
4. Set decibel (dB) PAD switches SW101, SW201, SW301, and SW401 to the appropriate
position. Switches are factory set at the 0 (0 dB signal level drop) position. If CO lines are
connected to a PBX or are in close proximity to the central office, set to the PAD positions to 3
to provide a -3 dB signal level drop between the PBX and CO.
5. Sensitivity jumpers SW102~SW402 are used mostly for dial pulse operation to adjust for dial
pulsing at different loop lengths. If close to the CO, the sensitivity should be set to low (L). As
the loop length increases, set it to high (H).
6. Insert the TDDU into the appropriate slot and apply firm, even pressure to ensure proper
mating of connectors.
TDDU Programming
Program 03: Specify Code 16 for slots that will support TDDUs. Make sure DTMF operation is
enabled.
Note
Program 03 can be skipped and Program 91 run instead.
Program *09: Assigns DID line extensions to route to station [PDNs].
Program 10-1: Enables or disables Two-line Conference.
Program 15: Assigns DTMF/Dial Pulse dialing, and additional attributes to each line.
Program *15: Makes tenant assignments.
Program 16: Assigns lines to line groups.
Program *17: Assigns intercept port for DID calls to wrong or vacant numbers.
Program 17: Tie and DID line options.
