Default command level
2: System level
Parameters
long: Matches 199.6-meter (655-feet) and longer cable length. The options for this parameter include
0db, -7.5db, -15db and -22.5db. The attenuation parameter is selected depending on the signal quality
received at the receiving end. No external CSU is needed.
short: Matches a cable length shorter than 199.6 meters (655 feet). The options for this parameter
include 133ft, 266ft, 399ft, 533ft and 655ft. The length parameter is selected depending on the actual
transmission distance.
Usage guidelines
You can use this command to adapt signal waveform to different transmission conditions such as the
quality of the signal received by the receiver. If the signal quality is good, you can use the default setting.
The CT1/PRI interface does not need an external CSU device.
Examples
# Set the cable length to 40.5 meter (133 feet) on CT1/PRI interface T1 2/0.

Default command level
2: System level
Parameters
set-number: Number of the channel set formed by timeslot bundling on the interface, in the range of 0 to
23.
timeslot-list list: Specifies the timeslots to be bundled. The list argument can contain multiple timeslot
numbers, each of which is in the range of 1 to 24. You can specify a single timeslot by specifying a
timeslot number, a range of timeslots by providing this argument in the form of { number1-number2 }, or
multiple timeslots by providing this argument in the form of { number1, number2-number3 }.
speed { 56k | 64k }: Speed of the timeslot bundle (the channel set) in kbps. If 56k is selected, the
timeslots are bundled into N × 56 kbps bundles. If 64k, the default, is selected, the timeslots are bundled
into N × 64 kbps bundles.
