Reintroducing a Gateway or ATA Into the System

If there are no more than five Gateways in the system (four PSTN Gateways and one T1 Gateway), and a Gateway or ATA screen

displays Synch Failed or Synchronizing for more than a few minutes, you may need to remove the Gateway or ATA from the

system and reintroduce it. This problem may have been caused by the Gateway or ATA having been part of a different network

or by a network disruption, which may have been caused by an AC power failure.

 To reintroduce a Gateway or ATA into the system:

1. Ensure that the Gateway or ATA is connected to the same LAN as other system Gateways, Desksets, and the PC you will

use to access the WebUI. Confirm that the first three octets of the IP address match other devices in the system.

2. Back up the system if you are reintroducing a Gateway and this is the only Gateway.

a. Log in to the WebUI as administrator using the Gateway or ATA IP Address shown on the Gateway or ATA display.

b. Click Device Management, then Back up/Restore, then System Settings in the WebUI Navigation Menu at left.

c. Click Back up System Settings and save the file to a specified location on your computer. You will need to locate

and retrieve this file later, so make sure you remember where you saved it. The file name will be in the format:

backup_system_[year]-[month]-[day]_[time].cfg.

If you back up the system less than one minute after creating another backup, you may overwrite the earlier file.

The system backup also saves ATA setup information.

3. Disconnect the Gateway or ATA from the network by unplugging the Ethernet cable from the Ethernet port located on the

front of the Gateway.

If you are reintroducing a Gateway or ATA, and there are other Gateways that are synchronized, this step is not

necessary.
