Inverting the Clock Signal Configuration Example
The following example configures the interface to invert the clock signal:
Router(config-if)# interface serial3/0/0
Router(config-if)# invert txclock ?
<cr>
Router(config-if)# invert txclock
Router(config-if)# invert ?
data Invert data stream
txclock Invert transmit clock
Router(config-if)# invert data
NRZI Format Configuration Example
The following example configures the interface for NRZI format:
Router(config-if)# nrzi-encoding ?
<cr>
Cyclic Redundancy Checks Configuration Example
The following example configures the interface for 32-bit CRC error-checking:
Router(config-if)# crc ?
16 crc word-size
32 crc word-size
Router(config-if)# crc 32
