Useful Information

Using with GPT / Siemens Equipment

When using the Cisco VG30D Voice Gateway with GPT / Siemens Realitis DX or iSDX, ensure
D Channel Link Tests on the PBX are switched off. Do this by using the RTCT command. See the
related manufacturer's user manual for further information.

Maintenance Replacement

In the unlikely event that an Cisco VG30D Voice Gateway should fail, you may need to replace it with
a maintenance spare that will need to be configured to the same settings as the field Cisco VG30D Voice
Gateway. This is best achieved by restoring a configuration backup file. Be aware that configuration
backup files are software version specific. To restore the configuration of the failed Cisco VG30D Voice
Gateway unit to the replacement unit, the replacement unit must first be loaded with the same software
version as the failed unit.
If the replacement Cisco VG30D Voice Gateway is at a different software level, the applicable software
must first be downloaded to it and then the restore performed. The software in the replacement unit can
then be upgraded. If this new software version is already pre-loaded in the replacement unit as its default
software, achieve upgrade by reactivating the default software. Otherwise, you must download new
software. When the upgrade completes, save a new configuration backup.
