PERFORMING DIAGNOSTICS FROM THE TERMINAL

Menu-9 Diagnostics

Menu-9, Diagnostics, provides access to diagnostic testing screens and monitoring configuration screens. Any test described in “Performing Tests from the Front Panel” on page 65 can also be performed from the terminal screen menus.

You can run several tests from your system’s internal diagnostics, shown in Menu-9, Diagnostics.

•Menu 9A — Physical Layer Diagnostics

•Menu 9B — Link Layer Diagnostics

•Menu 9C — Delay Monitoring Configuration

Menu-9A Physical Layer Diagnostics

This section describes the Menu-9A parameters and tests.

To verify connections and the E1 line, run the basic diagnostic and pattern tests from Menu-9A, Physical Layer Diagnostics.

Performing a Test from Menu-9A Physical Layer Diagnostics

To run a test from Menu-9A, Physical Layer Diagnostics:

1.Select the test and the port number in the Test field and set the Test length, USER1 and USER2 Pattern fields.

2.Follow the screen prompts.

Test results are shown in the upper portion of the screen.

The selections for ports on which the test is performed are Net1, Net2, and on some tests, All Net. Port is ignored with the Self Test, or Lamp test.

The Inject A Pattern Error option (to inject a single-bit error) is available only when the unit is sending a test pattern.

PERFORMING DIAGNOSTICS FROM TELNET

NOTE: Performing a test can cut off existing Telnet connections on the Ethernet and the NET Port. Since certain tests can cut off Telnet connections, only a subset of tests can be selected when the user logs onto the Dual Trunk E1 Router by Telnet through the NET Ports.

Certain tests prevent the Telnet session from being disrupted when you Telnet into the unit. Tests that can be run through a Telnet connection are listed in Table 8-3.
