Tie Lines:
DTMF and Dial Tone Circuit Setup
If the system has DTMF Tie Lines, be sure to
reserve at least one circuit for analog trunk
DTMF reception (type 0 or 2).
Use the following as a guide when allocating
DTMF receivers:
In light traffic sites, allocate one DTMF
receiver for every 10 devices that use them.
In heavy traffic sites, allocate one DTMF
receiver for every five devices that use them.
0 = Common Use
1 = Extension Only
2 = Trunk Only
Circuit/Resource
01 ~ 08 = 1
(Extensions)
Circuit/Resource
09 ~ 32 = 2
(Trunks)
Circuit/Resource
33 ~ 144 = 0
(Common)
When
GPZ-BS10 is
installed, 81 ~
144 are available
Basic Trunk Data Setup – Transmit Level
Customize the transmit level of the CODEC
Gain for each trunk.
Trunks 1 ~ 400
1 ~ 57 (-15.5 ~ +12.5dB in 0.5dB
intervals)
Basic Trunk Data Setup – Receive Level
Customize the receive level of the CODEC
Gain for each trunk as required.
Trunks 1 ~ 400
1 ~ 57 (-15.5 ~ +12.5dB in 0.5dB
intervals)
Basic Trunk Data Setup – Trunk-to-Trunk
Transfer
Enable loop supervision for each Tie Line that
should be able to place outgoing calls.
Analog Trunk Data Setup – Signaling Type
(DP/DTMF)
Set the outgoing signaling type for the tie trunk.
To set incoming signaling, refer to Program
34-01-02.
0 = Dial Pulse (10 PPS)
1 = Dial Pulse (20 PPS)
2 = DTMF
Trunk Group – Trunk Group Number
Program Tie Lines of similar type into the same
trunk group. The system uses trunk groups for
outgoing access to Tie Lines (i.e., Service Code
704 + group). Also see Program 34-05-01.
Trunk Port 1 ~ 400 =
Priority 1 ~ 400
Default = Trunks
1 ~ 400 assigned
to trunk group 1
with priorities
equal to the
trunk number.
Trunk 1 = Priority
1 Trunk 400 =
Priority 400.
Trunk Group Routing – Priority Order
Number
Set the priority order number 1 ~ 4.
0 = Not Specify
