To install an RDTU PCB
1. Set jumper wire plugs P1 (LB), P2, P3, and P4 to the Off position. See “Loop Back Testing”
on Page 8-14 for loop back testing procedures.
See “SW1 Equalizer Switch and Loop Back Jumpers (Internal Option)” on Page 8-2 for the
appropriate SW1 equalizer switch setting.
2. Insert the RDTU (component side facing right) into the appropriate slot and apply firm, even
pressure to ensure proper mating of connectors. (See “Slot Assignments” on Page 8-1 and the
appropriate Configuration chapter, Worksheet 2 for RDTU slot assignment recommendations.)
3. After installing the RDTU, gently pull the PCB outward. If the connectors are properly mated,
a slight resistance is felt.
System Programming for T1
1. Run Program 03: Assign the number of RDTU channels used and the cabinet slot number into
which the RDTU will be installed (see “Channelization” and “Slot Assignments” on Page
8-1 ). If 1~8 channel are required, assign code 71, if 1~16 channels are required, assign code
72, or if 1~24 channels are required, assign code 73 to the RDTU slot. Also, assign RRCS
code to RCTU if RDTU Tie/DID channels are DTMF.
Important!
Special consideration must be taken when installing Tie or DID T1 channels (see
Worksheets in
6 .
2. Run Program *41-2: Assign each channel for loop start, ground start Tie (Immediate or Wink),
or DID (Immediate or Wink). See Program *41-2 record sheet (unused channels can remain as
initialized—loop start).
3. Turn system power supply Off (five seconds) and On to activate Program 03 and *41-2
program data.
Note
These are the only programs relating to RDTU operation that require system power to be
cycled Off and On.
4. Run Programs 16, 40, 39: If an RDTU is connected to a fractional T1 circuit and all the RDTU
channels (8, 16, or 24) are not used, busy-out the unused CO lines from all line groups
(Program 16), all telephone buttons (Program 39), and restrict all stations from accessing the
unused lines (Program 40).
Example, if the Network fractional T1 provides 12 channels, set the RDTU connected to this
T1 for 16 channels in Program 03 (with code 72). If this RDTU is the first CO line PCB in the
system, the RDTU CO lines will be numbered 001~016. Use Programs 16, 39 and 40 to deny
use of all unused lines (i.e., lines 13, 14, 15, and 16). In this case the first 12 lines are usable;
lines 13, 14, 15, and 16 cannot be used. The CO lines on the next CO line PCB (any type)
following the RDTU PCB will start numbering at line 017.
5. Run Programs 15 and 30: If RDTU Tie and/or DID are dial pulse: Run Program 15-1, LED On
for each DP Tie/DID line and run Program 30, LED 11 On for each Tie/DID station port.
6. Run Program 17.
♦ LED 01: For RDTU Tie lines, set LED01 to allow (On) or deny (Off) Page and Voice
Announce on incoming calls to DK stations from the far end T1 Tie line stations. This
option (LED01) does not apply to RDTU DID lines—Page and Voice Announce is always
denied to incoming DID calls because of FCC “answer supervision” rules.
