GATM switch settings
There are two sets of DIP switches located on the rear of the GATM module. The left set allows you to
determine the DS30 bus and offset for the module.
The right set of switches allows you to manually configure a country profile operation, which is required
for earlier versions of software. However, BCM 3.5 software supports downloadable firmware for the
module for the North America, Taiwan, UK and Australia telephone profiles. To allow the GATM to
download the parameters for these countries and to allow for firmware upgrades, set all the country DIP
switches to 0 (zero/off) (factory default). The MSC telephony profile you choose must support the
appropriate country setting to ensure that the correct firmware installs.
The table below lists the possible DIP switch settings for the Mode and Country DIP switches.
