Automatic loop test
The automatic loop test checks the same functions as the self test. Unlike the
self test, it can be run automatically as part of the midnight routines.
Set the ATLP command to 1 as follows:
— If all 24 channels are idle at midnight, Meridian 1 software disables the
card and performs a self test on all channels.
— If any of the 24 channels are busy at midnight, software disables one idle
channel, chosen at random, and checks it while the card is enabled.
With the ATLP command set to 0, only one channel is tested. The channel
tested is randomly selected by software, and it cannot be specified.
