Command Implementation
Command: AT
Function: Attention Code
Values: n/a
Default: n/a
Description: This attention code precedes all command strings except the A/ command and es-
cape codes.
Command: RETURN
Function: Command Execution
Default: n/a
Values: n/a
Description: Press the RETURN (ENTER) key to execute a command. The RETURN key is fre-
quently abbreviated <CR> in command examples.
Command: +++AT<CR>
Function: In-Band Escape Code
Values: ASCII
Default: + (43)
Description: The +++AT command causes the ProxyServer to enter command mode, without
disconnecting the call, when it is online with a remote device. The default escape code is three +
characters, followed by the letters AT, up to 80 command characters, and a RETURN (press EN-
TER). The ProxyServer escapes to command mode, executes any commands in the string, and then
remains in command mode. Use the S2= command to change the escape character.
Command: <BREAK>AT<CR>
Function: Out-of-Band Escape Code
Values: n/a
Default: n/a
Description: This command places the ProxyServer in command mode while remaining online.
Enter a break signal, the letters AT, up to 80 command characters, and a RETURN (press ENTER).
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 impractical; therefore, many private networks send the number
of a called party by using a procedure called overlap sending, in which no sending complete indica-
tion is sent. Computer users, however, can automatically append the sending complete indication 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)
