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.
