Configuring ISDN NFAS for Japanese switch types
To introduce non-facility associated signaling (NFAS) support for Japanese switches, TAOS
unit supports implicit identification of the primary D-channel interface and explicit
identification of all other interfaces, as required by Japanese switches.
Following is an example of PRI/T1 line configuration for NFAS with a Japanese switch:
admin> read t1 { 1 1 1}
T1/{ shelf-1 slot-1 1} read
admin> set line-interface signaling-mode = isdn-nfas
admin> set line-interface switch-type = japan-pri
admin> set line-interface nfas-group-id = 0
admin> set line-interface nfas-id = 0
admin> set line-interface channel 24 channel =
nfas-primary-d-channel
admin> write
T1/{ shelf-1 slot-1 1} written
Configuring T1 R1 and R1-Modified (Taiwan) with ANI
and called-number processing
R1 is a multifrequency inband signaling system that uses a set of register signals known as
MFR1 tones as addressing signals. Each address (telephone number) is preceded by a KP pulse
and followed by an ST pulse denoting the end of addressing.
R1 signaling can optionally be used with Automatic Number Identification (ANI), which is
similar to Caller ID (CLID). When it is in use, you can specify whether to send an Automatic
Number ID Request (ANIR) to the switch. If you specify that the unit must send an ANIR to
