Menu-9, Diagnostics, provides access to diagnostic testing screens and monitoring configuration
screens. Any test described in

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.

ELNET
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 .
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.
