• Parameter name alias maps
• Partial string values, eventually combined into complete parameter values.
The GPP_* parameters are available for macro expansion within other provisioning
parameters. For this purpose, single-letter upper-case macro names (A through P)
are sufficient to identify the contents of GPP_A through GPP_P. Also, the two-letter
upper-case macro names SA through SD identify GPP_SA through GPP_SD as a
special case when used as arguments of the key URL option.
For example, if GPP_A contains the string ABC, and GPP_B contains 123, the
expression $A$B macro expands into ABC123.

All profile resync and firmware upgrade operations are controlled by the
Provision_Enable and Upgrade_Enable parameters. These parameters control
resyncs and upgrades independently of each other. These parameters also
control resync and upgrade URL commands issued through the administration
web server. Both of these parameters are set to yes by default.
In addition, the Resync_From_SIP parameter controls requests for resync
operations via a SIP NOTIFY event sent from the service provider proxy server to
the ATA. If enabled, the proxy can request a resync by sending a SIP NOTIFY
message containing the Event: resync header to the device.
The device challenges the request with a 401 response (authorization refused for
used credentials), and expects an authenticated subsequent request before
honoring the resync request from the proxy. The Event: reboot_now and Event:
restart_now headers perform cold and warm restarts, respectively, are also
challenged.
The two remaining enables are Resync_On_Reset and Resync_After_Upgrade_
Attempt. These determine if the device performs a resync operation after power-
up software reboots and after each upgrade attempt.
When enabling Resync_On_Reset, the device introduces a random delay
following the boot-up sequence before actually performing the reset. The delay is
a random time up to the value specified in Resync_Random_Delay (in seconds). In
a pool of these ATAs, all of which are simultaneously powered up, this introduces a
spread in the times at which each unit initiates a resync request to the provisioning
server. This feature can be useful in a large residential deployment, in the case of a
regional power failures.
