Acceptance tests
Automatic loop test
Automatic loop test procedures
553-2811-200 Standard 6.0 December 1994
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.
Activate automatic loop test procedures with the following steps:
1
Log into the overlay area.
2
Enter LD 60.
3
Find an idle channel on the DTI loop by using the STAT command. Enter
STAT L.
4
If all 24 channels are indicated BUSY by the response of the STAT
command, this test cannot be run. Otherwise, select an idle channel and
disable it. Enter DSCH L C.
5
Enter ATLP 0 or ATLP 1.
6
If the system response is not appropriate, refer to Digital Trunk
Interface/Computer-to-PBX Interface maintenance (553-2811-500) to
analyze the message.
7
Enter ENLL L C to enable DTI channel C.
8
Enter **** to abort LD 60.
