7.1.1.4 (Optional) Configuring the Digitmap of an MG Interface
This topic describes how to configure the digitmaps for certain special applications such as
emergency calls and emergency standalone. The digitmaps for common phone services are
issued to the AG by the MGC, and therefore such digitmaps need not be configured on the AG.
If the services such as emergency calls and emergency standalone are not required, the digitmaps
need not be configured.
Context
CAUTION
The digitmap configuration is relatively complicated. The information such as the meanings and
usage of the characters in a digitmap is defined in the protocol, and is not described here. This
topic provides only some basic information. It is recommended that you refer to the digitmap
description in ITU-T H248.1 (applicable to H.248) before configuring the digitmap.
l
A digitmap is a set of digit collection descriptors. It is a dialing scheme resident in the MG
and is used for detecting and reporting digit events received on a termination. The digitmap
is used to improve the efficiency of the MG in sending the callee number. That is, if the
callee number matches a dialing scheme defined by the digitmap, the MG sends the callee
number collectively in a message.
l
A digitmap consists of strings of digits with certain meanings. When the received dialing
sequence matches one of the strings, it indicates that the digits are collected completely.
l
To configure the emergency standalone function, you must configure the internal digitmap.
The H.248-based MG interface supports the following types of digitmaps:
l
Internal digitmap
l
Emergency call digitmap (due to call restriction in the case of an overload)
l
Automatic redial digitmap of the card service
provides the valid characters in the strings and their meanings in the H.248 protocol.
For details about the digitmap in the H.248 protocol, refer to ITU-T H248.1, which provides a
better guide to the digitmap configuration.
