TEL-B alternatively upon an incoming call. You may setup to ring TEL-A only or TEL-B only
by AT$CG (global call select setting) and AT$CP (receive priority setting). Telephone
numbers of TEL-A and TEL-B can also be distinguished by sub-addressing.
To setup the telephone number for TEL-A and TEL-B, you issue the following AT command.
l Setup line number to TEL-A
AT!D1 = 3930219 (where 3930219 is the applied line number from PTT)
l Setup telephone number to TEL-B
AT!D2 = 3930217 (where 3930217 is the applied DDI number from PTT)
l Setup SPID to TEL-A
AT!S1 = 50839302190101 (where 50839302190101 is the SPID number from PTT)
l Setup SPID to TEL-B
AT!S2 = 50839302170101 (where 50839302170101 is the SPID number from PTT)
l Setup data port number
AT%N = 3930217 (assign the telephone number to data port)
Note: SPID is necessary only for the Northern American users that connect with AT&T 5ESS or Nortel
DMS100 switch type or NI1 switch type.
4.3 Setting ISDN switch
To make your router work and connect to the ISDN network, you need to setup correct switch type
with your local ISDN exchange. Different countries may have different ISDN switch types.
Therefore you should consult your local PTT to setup the right switch type.
Type AT!Wn to Setup switch type:
n = 0 AT&T 5ESS
n = 1 Nortel DMS-100
n = 4 European NET3
n = 5 Australia switch
n = 6 Japan INS64 switch
n = 7 NI-1
Make an incoming or outgoing call to test the setting.
Note: if the switching type is setup wrong, the router may not place incoming or outgoing calls.
