Laut ETSI TS 100 392-5:
In V+D mode the set syntax is:
+CTSDS=<AI service>, <called party identity type>, [<area>], [<access priority>], [<end to end encryption>]
NOTE:
The <end to end encryption> parameter is included for future expansion.
In DMO mode the set syntax is:
+CTSDS=<AI service>, <called party identity type>, [<area>], [<priority level>], [<end to end encryption>],
[<comms type>], [<importance factor>]
CTSDS read syntax
+CTSDS?
The read command returns the read result code text as defined in clause 6.14.6.5.
6.14.6.5
CTSDS read result code text
In V+D mode the read result code text is:
+CTSDS: <AI service>, <called party identity type>, [<area>], [<access priority>], [<end to end encryption>]
In DMO mode the read result code text is:
+CTSDS: <AI service>, <called party identity type>, [<area>], [<priority level>], [<end to end encryption>],
[<comms type>], [<importance factor>]
6.17.11 Called party identity type
This parameter is used to indicate the type of identity to be used as the called party address. The associated identity used
in signalling will be interpreted differently according to this parameter. External subscriber number addresses are used
in association with a PSTN or PABX gateway.
• 0 - SSI;
• 1 - TSI;
• 2 - SNA (V+D only);
• 3 - PABX external subscriber number (V+D or DMO if via a gateway);
• 4 - PSTN external subscriber number (V+D or DMO if via a gateway);
NOTE:
•
The actual value of the gateway identities (PSTN, PABX) is provisioned in the MT and cannot be
changed over the PEI by AT commands.
5 - Extended TSI.
