Line
Parameters
The Line Parameters screen (Figure 4-7) allows reviewing and setting line
parameters for the selected element on the T1 circuit. This screen has the following
fields, most of which have user-selectable options. To send the new line
configuration to the unit, either press Enter on one of the fields, change the
Element selection, or exit the screen.
T1-NET Framing
Selects the type of framing for the network side of the element as either ESF and
D4.
T1-NET Line Code
Sets the network side line coding as either AMI and B8ZS.
T1-NET LBO
Sets the line build out for the network interface as either 0 dB, -7.5 dB, -15 dB, or
-22.5 dB.
PRM Enable
This field allows the T1.403 Performance Report Message, which is sent once a sec-
ond, to be Enabled and Disabled.
Zero Suppression
This field determines whether ones-density insertion is activated after 15 zeros.
The choices are Enable and Disable.
T1-NET Timing
Sets the timing source to synchronize the unit’s internal timing generators. Slips
are controlled to occur on frame boundaries at the network and DSX1 ports when
timing synchronization is lost.
