Vpacket 5100/6100 Series H.323 Telephony 47
Overview
The Address Translation Parsing Module (ATPM) is used to configure a dial plan for a system that
is running within an H.323 environment.
The ATPM provides a set of utilities to perform these tasks:
• Store and retrieve configuration information from Flash.
• Delete all configured entries.
• Generate a limited number of entries automatically.
• Managing the Flash configuration
On startup, the ATPM database can be configured in one of two ways:
If no valid configuration record is found in Flash, the ATPM database is set to some predefined
default.
If a valid configuration has previously been stored in Flash memory, then the ATPM database is
read from the record in the Flash.
The following commands support the management of the Flash-based ATPM configuration:
• atpm genlist <all | addr | hunt | dest> automatically generates lists based on the system
parameters and the IP addresses which are found in the three lists or tables (addr for alist,
hunt for hlist, and dest for dlist).
• atpm purge <all | addr | hunt | dest> deletes all entries from the ATPM configuration in all
lists or the specified list.
• atpm store stores all entries from the ATPM configuration into Flash memory. The Flash
ATPM sector will be erased before storing the current entries
atpm restores all ATPM entries from Flash to the ATPM tables. If some entries are already
configured in ATPM when the restore command is used, there could be errors reported due to
conflicting entries. It is best to execute an atpm purge all command before using a restore
command.
Storing and activating ATPM configurations
When a command has been issued, it is in the Active area where it can be stored or removed by
user operation. To implement a change, that command must be stored so when it is rebooted it
can be used by the ATPM.
To change the ATPM database, the configuring module must initiate the process by making an
ATPM update database request with the command atpm req.
The module can then start configuring the ATPM database after the ATPM responds with a
Database update granted response. The ATPM will give the Database Update granted after all the
translation and hunt sessions that were in progress during the update request command, are
closed. When the module has completed its configuration changes, it sends the CLI the ATPM
update database message atpm done.
