TESTING THE NETWORK CONNECTIONS

Once the network cabling and translations have been established between the local AUDIX system and one of the remote AUDIX systems, you are ready for the following:

1.Perform a connection test from the local system to the remote system (remote connection test). Remember that a remote system is any system in the network other than the system being tested. Even though a colocated system is not normally thought of as a remote system, to the local system it is.

2.If the remote connection test fails, perform the appropriate loop-around connect test (near-end connection test, local connection test, or 56/64 Kbps network loop-around test). The loop-around tests should be performed from the local system and, if nothing is found, performed from the remote system as well.

3.If the remote connection test and the loop-around test both fail, perform the internal channel and/or modem loop-around tests, as appropriate.

If at any time you get a ‘‘failed’’ response to a test, check the system : log form for possible reasons for the failure.

Step 1: Performing Remote Connection Tests

If you want to perform a test of the transmission path from the local system to a remote AUDIX system, select the appropriate remote connection test:

∙Remote DCP connection test

∙Remote switched RS-232 connection test

∙Remote switched RS-232 converted to DCP connection test

∙Remote dedicated RS-232 connection test

Step 1A: Testing Remote DCP Connections

This test involves a path similar to Figure 14-5,Remote Connection Test (Digital Path to Another AUDIX system) (DCP Mode 1 or 3) or Figure 14-6,Remote Connection Test (Analog Path to Another AUDIX system) (DCP Mode 2 — modem pooling). In the case of a colocated network, the path looks like Figure 14-7,Remote Connection Test (Colocated AUDIX system) (DCP Mode 3).

NOTE

Connection and modem loop-around tests are not supported on RS-232 ports that are converted to DCP mode 1 or DCP mode 3 using MPDM/M1* data modules. This is because the MPDM/M1* data modules do not support outdialing for these configurations. Use the DCP ports to test the connection to the remote system for these configurations.

1.Log in to the local system using the AUDIX system administration or maintenance terminal.

2.Go to maintenance : network form.
