3Com Router Command Reference Guide — V1.003.3.2 channel-set (/PRI Interface)Syntaxchannel-set set-number timeslot-list range [ speed { 56 | 64 } ]undo channel-set set-numberView/PRI interface viewParameterset-number: The channel set number formed by binding timeslots on an interface, it isin the range 0 to 23.range: Number of the bound timeslots, it is in the range 1 to 24. When specifyingtimeslots 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 specify multipletimeslots using the form of number1, number2-number3 simultaneously.speed { 56 | 64 }: Speed for binding timeslots, in kbps. When selecting parameter 56,the binding mode will be N x 56kbps. When selecting parameter 64, the binding modewill be N x 64kbps.DescriptionUsing the channel-set command, you can bind the timeslots of the /PRI interface aschannel sets. Using the undo channel-set command, you can cancel thecorresponding timeslot binding.By default, no channel-set is bound.The /PRI interface is physically divided into 24 timeslots, numbered from 1 to 24.When put into use, all the timeslots can be divided into multiple channel sets, andeach set will automatically create a Serial interface after being bound. The logicfeature of the serial interface will be the same as that of a synchronous serialinterface.The number of a Serial interface is represented by serialinterface-number:set-number. In which, number starts from the largest serial interfacenumber plus 1, and set-number is the number of channel-set.Only one timeslot binding mode can be supported on one /PRI interface at one time,that is, this command and the pri-set command cannot be used simultaneously.For related commands, see pri-set.42
