MultiModem ISI Hybrid Series, ISIHI-2S/2U 107
Chapter 5—TERMINAL ADAPTER AT Commands, S-Registers, Result Codes
S32 Escape Sequence Timeout
Unit: 100 ms
Range: 0255
Default: 20
Sets the time allowed in an escape sequence from the receipt of the A in AT to the receipt
of the carriage return. If the S32 time interval expires before you press ENTER, the escape
sequence ends. The default time is 2 seconds.
S50 Caller Line ID CLI
Unit: Decimal ASCII code
Range: 0 or 1
Default: 1 (enabled)
Sets whether the mechanism for identifying the two endpoints of a connection is enabled
or disabled. Since RING messages only appear for ISDN data calls, the CLI feature does
not define a means of conveying Calling Party information to the terminal for ISDN voice
calls. The CLI information is only included with the first RING message for a given
incoming call, and appears as follows:
RING FM: 5552000 TO: 5551000
If the Calling Party Number information is not included in the incoming SETUP message,
the RING message appears as follows:
RING TO: 5551000
If the Called Party Number information is not included in the incoming SETUP message,
the RING message will appear as follows:
RING FM: 5552000
If neither the Called Party Number nor the Calling Party Number is included in the
incoming SETUP message, the RING message will contain no additional information.
S52 Auto-Protocol Detection
Unit: Decimal ASCII code
Range: 0 or 1
Default: 1
Sets whether the mechanism for identifying V.120 or PPP, operation is enabled or
disabled. This is applicable for an ISDN data call and once determined by the TA, the
protocol used by means of the information conveyed by the SETUP message, then the
indicated protocol is activated. The default setting is 1, which enables the Auto-Protocol
Detection function.
