Step 2: Performing Loop-Around Tests
If the appropriate test in Step 1 fails, perform the appropriate loop-around test:
• Near-end connection test
• Local connection test
• Network loop-around 56 Kbps
• Network loop-around 64 Kbps
Step 2A: Testing the Near-End Connection
This tests the loop shown in Figure 14-12, Near End Connection Test (CO DCP Digital Loop-Around), the
loop shown in Figure 14-13, Near End Connection Test (CO DCP Analog Loop-Around), or the loop
shown in Figure 14-14, Near End Connection Test (CO RS-232 Analog Loop-Around).
1. Go to the system : translation : machine : audix/amis/call delivery form
and press ENTER . The local machine profile should be displayed.
2. The network data phone number (or dial string) must be the CO or network access code, a pause, and
the DID number associated with the local network hunt group.
a. Use a plus sign as a pause if testing DCP channels.
b. Use a comma as a pause if testing RS-232 channels. And make sure the dial string starts with
the attention code (ATDT).
3. If a change was required, press CHANGE or RUN , exit the form and go to the maintenance :
audits : fp form. Run a network data audit. This is necessary for R1V3 and R1V4 systems
only; it is not necessary for R1V5 and later systems.
4. Go to the maintenance : network form.
Set select test to 1. Set machine name to the name of the local AUDIX system. Press
CHANGE or RUN . Wait for the result. If the test is not successful, check the system : log
and/or go to Flowcharts For Troubleshooting the Network.
