Purpose
Cisco IADs that use long cables might experience high
error rates when operating at higher transmission speeds,
because the clock and data signals can shift out of phase.
If a DCE port is reporting a high number of bad packets,
inverting the clock by means of this command can often
correct the shift.
All serial interfaces support both nonreturn to zero
(NRZ) and nonreturn to zero inverted (NRZI) formats.
NRZ is the default; NRZI is commonly used with
EIA/TIA-232 connections in IBM environments. To
enable NRZI encoding on an interface, enter this
command.
Exits to global configuration mode.
Repeat Step 4 through Step 12 if your Cisco IAD has
more than one serial interface that you need to configure.
Returns to enable mode when you finish configuring the

interfaces.
