R0106-HP MSR Router Series Interface Command Reference(V7)

91
(Bit 1 is changed into bit 0, and bit 0 changed into bit 1.) After the inversion, at least one bit 1 is present
in every eight consecutive bits.
When AMI encoding is used on an E1 interface, data inversion eliminates the presence of multiple
consecutive zeros.
The data inversion setting must be the same on the CE1/PRI interfaces at two ends of an E1 line.
Examples
# Enable user data inversion on E1 2/3/0.
<Sysname> system-view
[Sysname] controller e1 2/3/0
[Sysname-E1 2/3/0] data-coding inverted
detect-ais
Use detect-ais to enable alarm indication signal (AIS) test on an interface.
Use undo detect-ais to disable AIS test.
Syntax
detect-ais
undo detect-ais
Default
AIS test is performed.

[Sysname-E1 2/3/0] detect-ais
display controller e1
Use display controller e1 to display information about CE1/PRI interfaces.
