3Com 3C13618 Command Reference Manual page 150

Parameter
range: Number of the bound timeslots, it is in the range 1 to 31. When specifying
timeslots to be bound, you can configure a single timeslot using the form of number,
or timeslots within a range using the form of number1-number2, or simultaneously
specify multiple timeslots using the form of number1, number2-number3.
Description
Using the pri-set command, you can bind the timeslots of CE1/PRI interface to be a
pri-set. Using the undo pri-set command, you can cancel the existing binding.
By default, no pri-set is created.
In the case of implementing pri-set binding, timeslot 16 on the CE1/PRI interface will
be used as D channels. Therefore, this timeslot cannot be bound independently. If
only this timeslot is to be bound, the binding activity will fail.
In the case of binding the timeslots on the CE1/PRI interface to form a pri-set,
timeslot 0 will be used to transmit synchronizing information, timeslot 16 as a D
channel to transmit signaling, and the other timeslots as B channels to transmit data.
At the time of binding, bind the timeslots except the timeslot 0 as one pri-set (as a D
channel, the timeslot 16 will be automatically bound). The logic feature of this pri-set
will be the same like that of an ISDN PRI interface. In the case of binding timeslots to
be a pri-set, if timeslots to be bound are not specified, all the timeslots except timeslot
0 will be bound to form an ISDN PRI interface similar to 30B+D.
After the timeslot binding, the interface will automatically create a Serial interface
owing the same logic feature as that of an ISDN PRI interface. The number of the
Serial interface is serial number:15. number starts from the largest serial interface
number plus 1.
Only one timeslot binding mode can be supported on one CE1/PRI interface at one
time, that is, this command and the channel-set command cannot be used at the
same time.
For related commands, see channel-set.
Example
# Bind the timeslots 1, 2, 8 to 12 of the CE1/PRI interface as a pri-set.
