can set the detailed timeslot as a B channel of a general serial port or a PRI interface through the
command line. When one or more timeslot has been configured as the PRI B channel of an E1
interface, the fifteenth timeslot will always be utilized by the PRI interface as the D channel of signal
alternation.
3.9.2 configure the PRI interface
To configure the PRI interface, you must input the command "controller E1" in the global configurative
mode firstly.
controller E1 <slot>/<group>
Pri-group timeslot num
Command 1：
Input the command "controller", it will prompt:
(00)E1
Please Input the code of command to be excute(0-0): 0
Input 0, choose the item "E1", it will prompt:
(00)<2-2>
(01)<cr>
Please Input the code of command to be excute(0-1):
Choose the corresponding item and input the slot number and group.
Command 2：
Choose the item 22 of parameter prompt, it will display:
(00)timeslots
Please Input the code of command to be excute(0-0): 0
Input 0， choose the item "timeslot", it will prompt:
(00)<1-31>
Please Input the code of command to be excute(0-0): 0
Choose the item 0, then input "num".
This command is used to set up a main workgroup and assign timeslots for the main workgroup. All the
timeslots can be assigned to B channel except 0 and 16. Each timeslot is a correspondence of a B
channel while each B channel is also a correspondence of a virtual 64K connection according to the
protocol encapsulated by D channel. You can't configure the D channel until you have set up a main
workgroup and assigned timeslots for B channels.
The configurative method of entering the D channel is : int serial slot/port:15。After you enter the D
channel, you can encapsulate protocol, set dial-up group and set the dial-up mapping of peer.
3.10 Configure the BRI interface
1. introduction of BRI interface
BRI is a kind of ISDN interface which consists of a single D channel plus 2 B channels. The D channel
is used to set up B channels and signal alternation channel of the interface. B channels are used to
transfer data.
2. Configuration of BRI interface
To configure the BRI interface ,you must under the ISDN BRI configurative mode firstly.
Command
List of timeslots which comprise the channel
Model Name
Configure E1 interface
Slot is the slot number of E1 controller
Group is the link number of E1 controller
num: you can assign many timeslot to one B channel. If
those timeslots are continuous, use the "-" to connect
them. Else , use ",".
