• The NRZI type setting for
-- The host side if the line encoding settings of the host and CPE do not
match.
-- The remote access side if the line encoding settings of the controller and
CPE do not match.
The NRZI type setting can be Mark or Space. The subscriber’s host and
remote access settings can be different.
You need these settings to set the NRZI Type ogical line parameter. Like the
NRZ Enabled parameter, the NRZI Type on a router connecting a host side is
unrelated to and can differ from that connecting a remote access side.
