Overview
This document introduced the details of provision of IP542N. IP542N supports 3 provision methods, which are TFTP (concluding option 66), HTTP and HTTPS.
With DHCP option 66, new IP542N will automatically attempt to resync to a specific configuration file by using TFTP server. The configuration file is requested and obtained by TFTP server from the IP address offered as one of the DHCP parameters. Any new IP542N connected to this LAN would automatically resync to the local TFTP server, initializing its internal state in preparation for deployment.
The IP542N also supports deploying remotely, user just need to set the value of profile rule. And set the recync parameters to auto resync to remotely TFTP/HTTP/HTTPS server.

Below is the provision page and introduction about each parameter in the Provision page. | ||
Parameter Name | Description | Default Value |
Provision Enable | Enable or disable the Provision functions. | Enable
|
Resync On Reset | Triggers a resync after every reboot except for reboot caused by parameter updates and firmware upgrades. | Enable |
Resync Random Delay | The maximum value for a random time interval that the device waits before making its initial contact with the provisioning server. This delay is effective only on the initial configuration attempt following device power-on or reset. The delay is a pseudo-random number between zero and this value. This parameter is in units of 1 seconds; the default value of 40 represents 40 seconds. This feature is disabled when this parameter is set to zero. This feature can be used to prevent an overload of the provisioning server when a large number of devices power-on simultaneously. | 40 seconds |
Resync Periodic | The time interval between periodic resyncs with the provisioning server. Set this parameter to zero to disable periodic resyncing. | 3600 seconds |
Resync Error Retry Delay | If the last resync was failure, IP542N will retry resync after the "Resync Error Retry Delay" time | 3600 seconds |
Forced Resync Delay | Maximum delay (in seconds) the VOIP ATA OR IP PHONE waits before performing a resync. The device does not resync while one of its phone lines is active. Because a resync can take several seconds, it is desirable to wait until the device has been idle for an extended period before resyncing. This allows a user to make calls in succession without interruption. The device has a timer that begins counting down when all of its lines become idle. This parameter is the initial value of the counter. Resync events are delayed until this counter decrements to zero. | 14,400 seconds |
Resync After Upgrade Attempt | Triggers a resync after every firmware upgrade attempt.
| Enable |
Option 66 | Allow or not allow DHCP option 66 to override server. | Yes |
Configfile | Configuration file is used for overriding the server | nf |
Profile Rule | This parameter is a profile script that evaluates to the provisioning resync command. The command is a TCP/IP operation and an associated URL. The TCP/IP operation can be TFTP, HTTP, or HTTPS. The file name can have macros, such as $MA, which expands to the device MAC address. Such as: https://192.168.20.17/param_$nf | Empty |
Phone Num1 for config | The first phone number which used to reboot IP542N in remote. | Empty |
Phone Num2 for config | The second phone number which used to reboot IP542N in remote. | Empty |
Upgrade Enable | Enables firmware upgrade operations independently of resync actions | Enable |
Upgrade Error Retry Delay | The upgrade retry interval (in seconds) applied in case of upgrade failure. The device has a firmware upgrade error timer that activates after a failed firmware upgrade attempt. The timer is initialized with the value in this parameter. The next firmware upgrade attempt occurs when this timer counts down to zero. | 3600 seconds. |
Downgrade Rev Limit | Enforces a lower limit on the acceptable version number during a firmware upgrade or downgrade. The device does not complete a firmware upgrade operation unless the firmware version is greater than or equal to this parameter. Not effect yet. | Empty |
Upgrade Rule | This parameter is a firmware upgrade script with the same syntax as Profile Rule. Defines upgrade conditions and associated firmware URLs. Such as: https://192.168.20.17/G502_F107_S334.bin | Empty |
