Dialing Method
n = 0 or 1
%A97=0 (En bloc)
support sending complete indication, (a signal that no more digits follow).
Adding this signal to a telephone number often is impractical. Therefore,
many private networks send the number of a called party using a procedure
called overlap sending, where no sending complete indication is sent.
Computer users can automatically add the sending complete indication to a
telephone number by choosing the en bloc method of sending, which results
in faster call setup. Use the %A97= command to select between the two
methods.
%A97=0 En bloc sending during call SETUP
%A97=1 Overlap sending during call SETUP
Network Switch Type
n = 0, 1, 2, 4, 5, or 6
!C0=2 (Net3)
supported by the TA. Factory default setting is !C0=2 (NET3).
!C0=0 AT&T 5ESS
!C0=1 Northern Telecom DMS-100
!C0=2 EuroISDN NET3
!C0=4 INS64
!C0=5 US NI-1
!C0=6 VN4
Data SPID
n = 0–20 character string
null string
service provider assigned at subscription time. The data SPID string can
have up to 20 characters. This command is not used if the switch type is set
to NET3.
Note: For DMS-100 switches, any ASCII character except the underline (_)
character is valid. For NI-1 and AT&T switches, only the digits 0–9 are valid.
Voice SPID
n = 0- to 20 character string
null string
service provider assigned at subscription time. The voice SPID string can
have up to 20 characters. It is not used if the switch type is set to NET3.
Note: For DMS-100 switches, any ASCII character except the underline (_)
