RDTU channels (8, 16, or 24) are not used, busy- n LED02 (Wink/Immediate)-This assignment
out the unused CO lines from all line groups is for RDDU, REMU, and PEMU lines only; it
(Program 16, all telephone buttons (Program 39), does not apply to RDTU tie or DIDTines. Use
and restrict all stations from accessing the unused Program *41-2 to assign RDTU lines for wink
lines (Program 40).
or immediate start.
Example, if the Network fractional Tl provides 12
channels, set the RDTU connected to this Tl 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.
W LED03-Toshiba recommends turning this
LED ON (initialized state) for all RDTU DID
lines to enable incoming DID calls to camp-on
busy stations. This is also necessary to allow
more than one DID line to ring into a station
simultaneously. LED03 does not apply to
RDTU tie lines.
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.
n LED04-For RDTU tie lines, LED04 is
normally OFF to enable dial tone to be
received from the far end tie line when calling
DK280 stations. For DID lines LED04 is
normally ON so RDTU DID lines do not send
dial tone to the Central Office (initialized state
is LED04 ON, No Dial Tone return).
7.
6. Run Program 17
n LEDOl-For RDTU tie lines, set LED01 to
allow (ON) or deny (OFF) Page and Voice
Announce on incoming calls to DK280
stations from the far end Tl tie line stations.
This option (LEDOl) does not apply to RDTU
DID lines-Page and Voice Announce is
always denied to incoming DID calls because
of FCC "answer supervision" rules.
Run *41-I-Use this program to assign the RDTU
(Tl) Line Coding method (B8ZS or AMI) and
signal Framing format (SF or ESF). Contact the
account representative of the company that is
providing the Tl span line (Local Central Office or
Long Distance Provider) to determine which line
Coding and Frame format will be used.
