Configuring T1 Cards
Configuring T1 R1 and R1-Modified (Taiwan) with ANI and called-number processing
the switch, you can also specify how long it waits before sending the request, and how long the
ANIR signal lasts.
The following parameters enable R1 signaling on T1 lines and specify the timing of certain
signals from the switch. These parameters are shown with their default settings:
[in T1/{ any-shelf any-slot 0 }:line-interface]
signaling-mode = inband
r1-use-anir = no
r1-first-digit-timer = 240
r1-anir-delay = 350
r1-anir-timer = 200
r1-modified = no
Following is an example that shows how to configure R1-Modified signaling (Taiwan) with
ANIR in a T1 profile:
admin> read t1 { 1 5 1}
T1/{ shelf-1 slot-5 1 } read
admin> set line signal = r1-inband
admin> set line r1-use-anir = yes
admin> set line r1-first-digit-timer = 360
admin> set line r1-anir-delay = 360
admin> set line r1-anir-timer = 220
admin> set line r1-modified = yes
admin> write
T1/{ shelf-1 slot-5 1 } written
Parameter Specifies
Signaling-Mode For T1 R1 signaling, you must set Signaling-Mode to R1-Inband.
R1-Use-ANIR Enables/disables ANI processing (CLID). It is set to No by
default. If set to Yes, the system performs ANI processing on
incoming calls.
R1-First-Digit-Timer Time in milliseconds to wait for the first digit from the switch after
sending the KP pulse. The default setting is 340 ms. The valid
range is from 0 to 1000.
R1-ANIR-Delay Time in milliseconds to wait before sending the ANIR signal after
receipt of the ST pulse from the switch. The default setting is
350 ms. The valid range is from 300 to 2000.
R1-ANIR-Timer Duration in milliseconds of the ANIR signal. The default setting is
200 ms. The valid range is from 180 to 400.
R1-Modified Enables/disables a modified version R1 signaling that is required
in Taiwan. It is set to No by default, which indicates regular R1
signaling (described in the ITU recommendation Q.310- 332).
TAOS units located in Taiwan must set this parameter to Yes.
