4.1 Diagnostics Menu
The Diagnostics Menu provides access to several embedded diagnostic facilities,
including loopbacks, built-in BERT, and viewing additional statistics.
There are multiple loopback options. Each of the eight T1/E1 links can be
independently looped back, and loopbacks can occur towards the line or towards
the backplane. A depiction of various loop types is provided in Figure 4-7.
The built-in BERT generator and testers can be used along with loopbacks to test
and determine the status of the D8E1T1 links. They may also be used in
conjunction with diagnostic facilities on other DXC-100 cards to qualify operation
of the backplane connections. Statistics displays are also provided for monitoring
and diagnostic purposes.
