tni_ones_density
This T-1 parameter is used to defeat the CSMIM-T1 ones density monitor.
The T-1 engine has a built in ones density monitor that will provide the
network with the correct number of one pulses. The ones density monitor
does the following:
1. The monitor does not allow the CSMIM-T1 to transmit more than
fifteen consecutive zeros.
2. The monitor ensures that the CSMIM-T1 has at least N ones in every
time window of 8X(N+1) bits, where N=1 to 23.
This parameter has an on and an off setting. This parameter should be set
to on when using AMI coding. The default is
off .
4.5 SET T-1 PARAMETERS EXAMPLE
The following is an example of the show , set , and reset commands and
provides actual screens to reference while proceeding. What we have
done is show the T-1 info screen, set the T-1 bypass to N allowing the T-1
line to interface with the module, change the loop start setting to wink
start, and reset the software at the appropriate times. This is an actual
example of how to make the T-1 module functional.
