Using Site Manager
To configure BERT diagnostics, complete the following tasks.
See “Testing MCE1 and MCT1 Lines,” later in this chapter, for more information
about running BERT diagnostics.
Enabling or Disabling Fractional T1 Loopback Detection
QMCT1 and QMCT1 w/ DS0A link modules only can detect and generate
fractional T1 (FT1) loopback codes as specified in ANSI T1.403 Annex B.
FT1 loopback (channel loopback) is an ANSI-standard 127-octet loop. FT1
loopback detection allows remote test equipment to put one channel (logical line
or DS0 group) on any port into loopback testing mode without affecting the other
logical lines.
See “Running Logical Line Tests” later in this chapter for information about
generating fractional loopback codes.
Site Manager Procedure
You do this System responds
1. Enable BERT mode on the QMCT1 or
DMCT1 logical line.
Click on
Help
or see the parameter
description on page A-41.
Site Manager enables BERT mode.
2. With BERT mode enabled, specify the bit
pattern transmitted during BERT
diagnostics.
Click on
Help
or see the BERT Test
Pattern parameter on page A-41.
Note:
Although the DMCT1 net module does not support FT1 loopback, it
does provide BERT testing on selected DS0s, as described in
“Running Logical Line Tests” later in this chapter.
