Over-The-Link Downloading
Over-the-link (OTL) code downloading allows C2000 transmitter controller (C2000)
software, alarm matrix setup, and exciter software to be downloaded over the C2000 link
channel.
software, alarm matrix setup, and exciter software to be downloaded over the C2000 link
channel.
To properly use OTL downloading, C2000 units must be programmed for the correct
control group, site ID, and unit ID, which are integral to C2000 hardware and software.
When information is downloaded over the link channel, the control group, site IDs and/or
unit IDs that are to receive the code must be specified.

When information is downloaded over the link channel, the control group, site IDs and/or
unit IDs that are to receive the code must be specified.
Caution
If the control group, site ID, and unit ID are not
specified, all units in the system accept the
download information. In a mixed system, this can
result in some of the transmitters being off the air.
An example of this would be a GL-T8600 exciter
receiving a GL-T8500 exciter programming code.
The GL-T8600 exciter would not operate with this
software and could result in a site visit to correct
the problem.

Programming of control groups and site IDs is done via the C2000 front port with a local
connection or through a modem from a remote location. The control groups should be setup
as a group of transmitters having the same configuration. For example, all GL-T8500 trans-
mitters could be in one control group and GL-T8600 transmitters be in another. This would
allow one to download exciter software to all GL-T8500 transmitters at one time by
selecting their control group. Any transmitter with a different control group would not
accept the download information.

Site ID must be different for each site location, and is used when downloading information
to a specific site location. If there are multiple units at the same site, the site ID and unit ID
need to be specified to download to a specific unit. If the unit ID is not specified, all units
at that site accept the download.

at that site accept the download.
Unit ID is programmed with a rotary switch in the C2000; it must be different for each
C2000 at a site location. To download one specific unit, both site and unit ID must be
specified for that unit; the unit with that site ID and unit ID is the only one that accepts the
download.

On-The-Fly Channel/Mode Changing
Different paging formats may require different digital deviation and offsets of paging data
on the same RF carrier frequency. In the past, the only way to meet the different deviation
requirements on the same frequency was to program two different channels for the same
RF carrier frequency and then program those same two channels for a different digital
on the same RF carrier frequency. In the past, the only way to meet the different deviation
requirements on the same frequency was to program two different channels for the same
