LBI-39076B

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
02 since 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.
