4.1.3 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 signalling protocols, such as DSS1, DSS2, and

SS7, support a sending complete indication; i.e., a signal that no more digits will

follow. However, appending such a signal to a telephone number is often impracti-

cal; therefore, many private networks send the number of a called party by using a

procedure called overlap sending, in which no sending complete indication is sent.

Computer users, however, can automatically append the sending complete indica-

tion to the 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, 3, 4, 5, or 6

Default: !C0=2 (Net3)

Description: Use the !C0= command to select one of the seven network switch

types supported by the MTA128ST. The factory default setting is !C0=2 (NET3).

!C0=0 AT&T 5ESS

!C0=1 Northern Telecom DMS-100

!C0=2 Euro-ISDN NET3

!C0=3 1TR6

!C0=4 INS64

!C0=5 US NI-1

!C0=6 VN4
