R3303-HP HSR6800 Routers Interface Command Reference

102
ensures that at least one out of every eight bits is a one. When AMI encoding is adopted on a T1
interface, the use of data inversion can eliminate the presence of multiple consecutive zeros.
On the CT1 interfaces at two ends of a T1 line, you must use the same data inversion setting.
Examples
# Enable user data inversion on CT1 interface T1 2/0/0.
<Sysname> system-view
[Sysname] controller t1 2/0/0
[Sysname-T1 2/0/0] data-coding inverted
display controller t1
Use display controller t1 to display information about one specified or all CT1 interfaces.
Syntax
display controller t1 [ interface-number ] [ | { begin | exclude | include } regular-expression ]

Parameters
interface-number: Interface number. In conjunction with the t1 keyword, it specifies a CT1 interface.
|: Filters command output by specifying a regular expression. For more information about regular
expressions, see Fundamentals Configuration Guide.
begin: Displays the first line that matches the specified regular expression and all lines that follow.
exclude: Displays all lines that do not match the specified regular expression.
include: Displays all lines that match the specified regular expression.
regular-expression: Specifies a regular expression, a case-sensitive string of 1 to 256 characters.
Examples
# Display information about interface T1 2/0/0.
