7.9.1 TCAP_CONFIG – Configure TCAP
Synopsis
The TCAP_CONFIG command provides the TCAP operating parameters and, when used, must appear after
the SCCP_SSR or DTC_SSR commands. This command should only be used when an SCCP_CONFIG or
DTC_CONFIG command is present. The use of the TCAP_CONFIG command is not required and TCAP is
configured with default values if the TCAP_CONFIG command is not present.
By default, TCAP is configured with 32k incoming and 32k outgoing dialogs. The TCAP_CONFIG command
must be used to change these parameters for systems requiring a different number of dialogs.
Syntax
TCAP_CONFIG <base_ogdlg_id> <nog_dialogues> <base_icdlg_id> <nic_dialogues> <options> <dlg_hunt>
[<addr_format>]
Example
TCAP_CONFIG 0x0000 8192 0x8000 8192 0x0000 0

The TCAP_CONFIG command includes the following parameters:
• <base_ogdlg_id>
