Step 2C: Testing the 56/64 Kbps Network Connection
This tests the connection between the local AUDIX system and a 56 Kbps or 64 Kbps serving office (SO),
as shown in Figure 14-18, 56/64 Kbps Network Loop-Around Test.
While a channel is in loopback mode, it will be unavailable to send information to remote systems or
receive information from remote systems. Also, if you put a channel in loopback mode, any active calls
will be dropped. It is therefore recommended that before you perform this test you check the status of the
channel. It is also not a good idea to perform this test during peak traffic times.
1. Go to the maintenance : network form. Set select test to 7 for to test a 56 Kbps network
connection or to 8 to test a 64 Kbps network connection. Press TAB to get to the channel field and
the specify the channel (1-6) you want to test. Press CHANGE or RUN and wait for the result.
NOTE
To test channel 5 or 6 (RS-232 channels) you need an MPDM/M1* between the
AUDIX system and the PBX.
2. Have the serving office place a call to the telephone number assigned to the channel you specified on
the maintenance : network form. If the test is successful, any data the serving office sends
over the AUDIX channel will be echoed back.
3. Go to the maintenance : network form. Set select test to 9 to take the channel out of
loopback mode. Press TAB to get to the channel field and the specify the channel (1-6) you want to
take out of loopback mode. Press CHANGE or RUN and wait for the result.
