Configuring MCE1 and MCT1 Services

Setting the BERT Test Pattern
When a port is in BERT mode, it can generate patterns such as all ones, all zeros,
or a QRSS pattern. Use Site Manager to set the BERT test pattern.
See the BERT Test Pattern parameter on page A-54 for information.
Setting the Line-Coding Method
How you set line coding depends on whether you are testing an MCE1 or MCT1
line:
The MCE1 port uses HDB3 transmit and receive line coding by default. You
can select AMI line coding instead.
The MCT1 port uses B8ZS transmit and receive line coding by default. You
can select AMI line coding instead.
For a description of these line-coding methods, see “Setting the MCE1 Line
Coding” or “Setting the MCT1 Line Coding” on pages 7-9
and 7-19 respectively.
Setting the Line Type
The line-type setting depends on whether you are testing an MCE1 or MCT1 line:
MCE1 line -- Select the appropriate frame format for the associated E1
equipment you are testing:
E1 -- The default
E1 CRC -- Adds a 4-byte CRC trailer at the end of each frame
MCT1 line -- Select the appropriate frame format for testing:
ESF -- The default; FDL port actions apply
SF/D4
For a detailed description of SF and ESF formats, see “Setting the T1 Frame
Type in Chapter 6.
