Chapter 6
Diagnostics
The
D
IAGNOSTICS
menu allows you to initiate loopback and BERT
tests from the OSU 300. Figure 6-1 on page 6-2 shows the main
D
IAGNOSTICS
menu. Perform tests for the entire DS3 or for an
individual DTE port. If a Quad DSX-1 card is installed, activate
loopback tests for an entire card (all four DSX-1s) or for an
individual DSX-1 port.
To choose a DTE port from the left column of the menu, select the
port’s corresponding number and press Enter. The individual port
menus provide loopback and BERT selections. BERT configuration
options and results are given in the right column of the main
D
IAGNOSTICS
menu.
Diagnostic selections are described in the following portions of this
chapter:
• DS3 on page 6-2
• DTE Ports 1-4 on page 6-3 (HSSI and V.35 Port Options)
• Quad DSX-1 Diagnostic Options on page 6-7
• BERT Configuration on page 6-12
You can only perform a BERT test on one DTE port at a time. If a BERT
test is already in progress and a second BERT test is selected for another
port, the first test is discontinued.
Loopback tests may be performed simultaneously on all four DTE ports.
