Using the BCC
To enable or disable NRZI encoding, navigate to the logical-line prompt (for
example,
stack; mce1/1/2/1; logical-line/mce1-121-1) and type:
nrzi-encoding
variable
For example:
logical-line/mce1-121-1# nrzi-encoding enabled
To set the NRZI type, navigate to the logical-line prompt (for example, stack;
mce1/1/2/1; logical-line/mce1-121-1) and type:
nrzi-type
variable
For example:
logical-line/mce1-121-1# nrzi-type space
Using Site Manager
See the NRZI Enable parameter on page A-42 for information. For information
about the NRZI Type parameter, see page A-43.
Setting the Transmit Queue Length
In the BCC, the Transmit Queue Length parameter specifies the transmit queue
length for each logical line. This is the maximum number of buffers present on the
transmit descriptor ring on a logical line at any given time.
You can set this parameter from 0 to 512. A value of zero causes the router to use
its default values.
Nortel Networks recommends that you do not change the default setting of this
parameter without careful consideration of the traffic flow in and out of the T1/E1
logical lines.
See “
Setting Buffer Credits for MCE1” on page 7-14 for more information.
Caution:
You can affect router performance severely by over-allocating buffer
credits.
