Note: The transmit attenuation value is best obtained by experimentation. If the
signal received by the far-end equipment is too strong, reduce the transmit level by
entering additional attenuation.
Example:
The following example sets the transmit attenuation to the appropriate levels for a
cable between 134 and 266 feet long:
X330WAN-2DS1-1(config-controller:1)# cablelength short 266ft
channel-group (Controller context)
Use the
channel group
command to create a channel-group (also referred to as
"ds0 bundle"). A channel group can be the underlying interface for a PPP session.
This command creates a logical interface, which is identified by a port number, a
colon, and a channel group number. For example, channel-group 8 on E1 port 2
would be referred to as "2:8" in all places where a channel-group is needed as a
parameter.
The syntax for this command is:
channel-group <channel-num> timeslots <timeslot-list
>
speed
{56
| 64}
Note: The Speed option can be performed only when the controller is set to T1.
channel-num ID number to identify the channel group. The valid
range is from 0 to 23 for T1 lines and from 0 to 30 for
E1 lines.
timeslot-list Timeslots (DS0s) to include in this channel group.
The valid timeslots are:
• 1 to 24 for T1
• 1 to 31 for E1
Values can be either separated by a "," (to indicate a
list) or a "-" (to indicate a range)
speed Acceptable values are 56 or 64.
