Configuring BERT Patterns

To enable BERT diagnostics on a DMCT1 or QMCT1 logical line:

Set BERT mode to Enable.

See the BERT Mode parameter on page A-41

for information.

Set the bit pattern to be transmitted during BERT testing, or keep the

default value of all ones.

When a line is in BERT mode, it generates patterns such as all ones, all zeros,

or a QRSS pattern. Valid test pattern options are as follows:

• Zero

• Ones

• QRSS

• 2e15

• 2e15 Inverted

• 2e20

• 2e23

• 2e23 Inverted

See the BERT Test Pattern parameter on page A-41

for information.

Configuring Fractional Loopback Requests

To configure channel-based loopback testing on a QMCT1 or QMCT1 w/ DS0A

logical line only, set one of the following fractional loopback modes to Enable:

• Accept Fractional Loopback -- Enables the logical line to send ANSI-standard

FT1 loopback codes

See the Accept Fractional Loopback Code parameter on page A-41

for

information.

• Accept Fractional Loopback (Proprietary) -- Enables the logical line to send

SNMP-based logical line loopback codes

See the Fractional Loopback parameter on page A-37

for information.
