Synchronous Line Parameters
You access the synchronous line parameters from the Configuration Manager.
Parameter: NRZI Type
Path: Configuration Manager > > QMCT1 Connector > MCT1 Logical Lines
Default: Mark
Options: Mark
| Space
Function: The software uses this parameter only if you installed a QMCT1 DS0A link
module and set the NRZI Enable parameter to Enable. This parameter specifies
the NRZI encoding format in the frame on the logical line. The Mark format
uses a 0-bit to indicate a state change and a 1-bit to indicate no state change. The
Space format uses the opposite.
Instructions: Ignore if you set NRZI Enable to Disable.
Otherwise, if you are configuring the router connection to
• The host side, determine which device on that side is using NRZI, and match
this parameter to the encoding type used by that device.
• The remote access side, determine which device on that side is using NRZI,
and match this parameter to the encoding type used by that device.
