Switch Configuration Commands
Use the following

commands to select your network switch type (e.g., EuroISDN Net3) and to specify
other information required to make an ISDN connection.
Command: %A97=n
Function: Dialing Method
Values: n = 0 or 1
Default: %A97=0 (En bloc)
Description:Standardized ISDN signaling protocols such as DSS1, DSS2, and SS7
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
Command: !C0=n
Function: Network Switch Type
Values: n = 0, 1, 2, 4, 5, or 6
Default: !C0=2 (Net3)
Description:Use the !C0= command to select one of the six network switch types
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
Command: !C6=n
Function: Data SPID
Values: n = 0–20 character string
Default: null string
Description:Use !C6= to specify the data service profile identifier (SPID) that the ISDN
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.
Command: *!C6=n
Function: Voice SPID
Values: n = 0- to 20 character string
Default: null string
Description:Use *!C6= to specify the voice service profile identifier (SPID) that the ISDN
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 (_)
character is valid. For NI-1 and AT&T switches, only the digits 0–9 are valid.
