T1/E1 & T3/E3 Commands
XSR CLI Reference Guide 2-69
Example
The following example configures the E3 controller in slot 1, card 2 with line source clocking and
international bits of 0 and 0:
XSR(config)#controller e3 1/2/0
XSR(config-controller)#clock source line
XSR(config-controller)#international bit 0 0
invert data
For T1/E1 controllers only
This command inverts the data stream. Data inversion is a method of avoiding excessive zeroes
that is superseded by the use of B8ZS line encoding. However, in cases where the network or
remote node does not support this type of line coding, data belonging to an HDLC stream can be
inverted to satisfy requirements of the line.
Syntax
invert data
Syntax of the “no” Form
Disable inverting the data stream by using the command’s no form:
no invert data
Default
Data is not inverted.
Mode
Interface configuration: XSR(config-if<xx>)#
Example
The following example enables data inversion on the full‐rate T1 interface in NIM card 1, port 0:
XSR(config)#interface serial 1/0
XSR(config-if)#invert data
linecode
For T1/E1 controllers only
This command defines the encoding type for T1/E1/ISDN‐PRI lines. Configuration must match the
required setting of the service provider. The service provider determines which line encoding type
is required. The following three encoding types can be configured:
• AMI (Alternate Mark Inversion)
• B8ZS (Bipolar 8 Zero Substitution – T1 only)
• HDB3 (High‐density Bipolar 3 – E1 only)
