T1/E1 & T3/E3 Commands
cablelength
For T3 controllers only
This command specifies the distance of cabling from the XSR to the network equipment for a T3
NIM card only.
Syntax
cablelength feet
feet
Syntax of the "no" Form
The no form of this command sets the cablelength to the default value:
no cablelength
Mode
Controller configuration:
Default
224 feet
Example
The following example configures the T3 controller in slot 1, card 2 with line source clocking, M13
framing, in channelized mode, and a cablelength of 225 feet:
XSR(config)#controller t3 1/2/0
XSR(config-controller<T3-1/2/0>)#channelized
XSR(config-controller<T3-1/2/0>)#clock source line
XSR(config-controller<T3-1/2/0>)#framing m13
XSR(config-controller<T3-1/2/0>)#cablelength 225
cablelength long
For T1 controllers only
This command decreases the pulse from the transmitter for long haul applications on T1
controllers only. In long haul applications (length of the haul longer than 655ft, CSU interface) the
transmit pulse masks are optionally generated according to ANSI T1.403 to reduce crosstalk on

Note: Although you can specify cable length from 0 to 450 feet, the XSR recognizes only two
ranges: 0 to 224 and 225 to 450. For example, entering 35 feet selects the 0 to 224 range. If you
later change the cable length to 40 feet, there is no change because 40 falls within the 0 to 224
range. But, if you change the cable length to 350, the 225 to 450 range is selected. The actual length
you enter is stored in the configuration file.
