5.(Master GTI only) Disconnect the two Site Controller data link plugs from the back of the Master GTI.
6.Disconnect the PCM Data Bus from the back panel of the GTI. If there are two cables (or one cable and a termination) quickly reconnect the two cables (or the cable and the termination) back together without the GTI and let hang).
NOTE
It is necessary to temporarily separate the two PCM Data Bus cables when disconnecting them
from a GTI. While separated, all GTIs connected to higher numbered radio channels will not be connected to the Master GTI and may cause interconnect abnormalities such as dropped calls and/or alarms.
Use the preceding procedure in reverse to reconnect the GTI to the MASTR III EDACS Repeater.
ELI SOFTWARE UPGRADES
CAUTION
Using
When upgrading to a new ELI software release number or adding new GTIs to an existing ELI system, you must make sure that all software versions and all GTI Main Board revision numbers used in that ELI system (each GTI and IAM) are compatible for that ELI software release number. Using
Three plans for upgrading an existing ELI system from release 1.0 to release 1.1 software are given here. Each of the plans require that the ELI system be completely taken out of service while changes are made to the Master GTI unit. The differences are in how many (if any) GTI units you put in use before you have finished making changes to all of the GTI units.

Plan A is to take the ELI system completely out of service while changes are made to the Master GTI unit and all regular GTI units. This plan is easiest for those making the changes to the GTI units, but hardest for those wanting to use the ELI system while the changes are being made.
Plan B is to briefly take the ELI system completely out of service while the first half of the regular GTI units are disconnected, then run the ELI system at half capacity while changes are made to the first half of the regular GTI units, then take the ELI system completely out of service while changes are made to the Master GTI unit, and then run the ELI system at half capacity while changes are made to the second half of the regular GTI units. This plan is harder for those making the changes to the GTI units, but is easier for those wanting to use a
Plan C is to take the ELI system completely out of service while changes are made to the Master GTI unit, and then run the ELI system with only the Master GTI unit while changes are made to the first regular GTI unit. As the changes for each regular GTI unit or group of regular GTI units are completed, they can be reconnected and brought back into service. This plan is harder for those making the changes to the GTI units, but is easier for those wanting to use a
