Media Gateway Parsers

This section describes the Dialogic
hook) integration parsers for analog and T1 CAS integrations, and the display parsers for digital
integrations. These parsers allow the user to define the meaning of either the in-band/on-hook
integration strings or display strings received from the telephony network. For this discussion, the
term parser will be used when referencing all three variants listed above. Various options for
entering the configuration data, parser syntax rules, and several examples are presented.
Note: The information in this section applies to all models of the Dialogic
(DMG1000) and Dialogic
Information about the Media Gateway parsers is included in the following sections:

The parser allows the user to enter rules that define the meaning of the strings that can be received
from the telephony network. The Media Gateway will use these rules to parse the strings and
extract the source party information, destination party information, call reason (direct, busy, ring-
no-answer, etc.), and call origin (internal or external). Note that the default rules supplied for the
display parsing on digital units handle most scenarios, but the analog CPID parsing default rules
are only included to provide examples for the user.
The user configurable rules (collectively known as the configuration data) contain expressions that
represent the various types of integration strings available on the telephony switch interface. The
configuration data contains rules and expressions that specify the location of the source,
destination, reason, and origin information in the integration or display string.
6.1 Configuration Options
The user can access the parsing configuration data in several different ways:
• Media Gateway configuration file (*.ini) which allows the user to use the import/export Web
page to upload new configuration data or to download existing configuration data for review.
• Text file (must have an .adt file extension) containing only the configuration data.
• The cpid.htm hidden Web page.
For type I and II analog parsing rules only, the analog page on the Web interface.
•
Figure 29 shows the default analog parsing configuration (used for either type I or II CPID) on the
analog Web page. Figure 30 shows this same data as it appears in the *.ini file. Figure 31 shows a
sample, downloadable text based *.adt file. Figure 32 shows the generic CPID configuration page
available to all emulating units with the example showing the default Mitel digital display parsing
rules.
