The location of the Application Software and Personality PROMs on the PROM card is shown in Figure
7.When replacing PROMs, be sure to get each new PROM in the correct location and the notched end facing the right direction. Be especially careful of location numbers 01 and
02since these numbers are used for both types of PROMs.

Application Software PROMs
Each of the 14 Application Software PROMs must be marked 344A3265Gx, where x = 5 or higher. (x = 4 or lower does not support the ELI option.) Figure 8 shows where to find the software revision number and the PROM location number on a typical Application Software PROM label.

Personality PROMs
Each of the two Personality PROMs must be replaced when you install the ELI option, regardless of the version of the Application Software PROMs. The new Personality PROMs must have ELI selected as the interconnect mode. In addition, the new Personality PROMs should have other ELI parameters programmed correctly (see the Configuration section). Figure 9 shows where to find the PROM location number on a typical Personality PROM label.

4. RADIO CHANNEL ASSIGNMENTS
The 4th step to install the ELI option, is to assign each GTI unit (including the Master GTI) and the optional IAM to a radio channel. Once this relationship is established, the telephone interface inside the GTI units and the DIP switches on the side of the GTI units can be set up. Then the GTI units can be mounted.
Although the optional IAM is not functionally associated with any specific radio channel, it is mounted with a specific radio channel as if it was. This forces it to be in a predictable location relative to the GTI units so that cables of the correct length can be provided for its connection.
Until they are mounted there is an opportunity to get them mixed up and mounted with the wrong radio channel. To assure that this doesn’t happen, the radio channel assignments can be temporarily marked on the GTI units, or the GTI units can be set up and mounted one at a time.
The method used to assign GTI units to radio channels is to assign all of the standard GTI units first, followed by the Master GTI, and finally the optional IAM. Start by assigning the first standard GTI to the highest numbered radio channel, the next GTI to the next highest numbered radio channel, and so on until all standard GTI units, then the Master GTI, and finally the optional IAM (if supplied) are assigned.
