Chapter 5—TERMINAL ADAPTER AT Commands, S-Registers, Result Codes
T
erminal Adapter
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, X.75, 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.
S53 Maximum Frame Size (X.75)
Unit: Decimal ASCII code
Range: 0-2048
Default: 2048
Sets the maximum size of data frames in X.75 mode. This register can be configured to
contain as many as 2048 characters per frame, and is the TA’s default value
