R3102-R3103-HP 6600/HSR6600 Routers Interface Command Reference

104
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 133 ft, 266ft, 399ft, 533ft and 655ft. The length parameter is selected depending on the actual
transmission distance.
Usage guidelines
You may 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 interface does not need an external CSU device.
Examples
# Set the cable length to 40.5 meter (133 feet) on CT1 interface T1 2/0/0.

channel-set (CT1 interface)
Use channel-set to bundle timeslots on the CT1 interface into a channel set.
Use undo channel-set to remove a specified or all channel sets.
Syntax
channel-set set-number timeslot-list list [ speed { 56k | 64k } ]
undo channel-set [ set-number ]
Default
No timeslots are bundled into channel sets.

Parameters
set-number: Number of the channel set formed by timeslot bundling on the interface. It ranges from 0 to
23.
timeslot-list list: Specifies the timeslots to be bundled. The list argument can contain multiple timeslot
numbers, each of which ranges from 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.
