3.2.7 Configuring the Basic Parameters of ISDN PRI Interface

If DSS1 subscriber signaling of ISDN PRI interface is adopted between the router and the switch, the integrated transmission of voice and data is supported, in other words, in one E1 trunk connecting the router and the switch, voice signal and data signal occupy different B channels for transmission respectively. When the function of integrated transmission of voice and data is adopted, it is required to configure DDR dialing in the corresponding serial port of ISDN PRI group, so as to implement data transmission.

After ISDN PRI group is successfully configured, the system will, on one hand, generate the corresponding voice port of the PRI group according to the E1 port number where the current PRI interface lies: the voice port number is “E1 port number:15”; on another hand, the system will generate the corresponding serial port of PRI group according to the current serial port number: the number of the new port is “(the number of the serial port where PRI group lies + the total number of serial ports) : 15”.

After the channel-group is successfully configured, the system will create the corresponding serial port of the channel-group automatically. The number of the new serial port is “the number of the serial port where the channel-group lies + the total number of the serial port)”.

Please use commands controller e1 and interface serial in global configuration mode, and perform other configurations in E1 controller interface configuration mode.

Table VC-3-7Configuration Commands of ISDN PRI Interface

Operation	Command
Enter E1 controller interface configuration mode	controller e1 port
Create channel-group for specified TS	channel-groupchannel-group-no timeslots timeslots-list
Delete the specified channel-group	no channel-group channel-group-no
Set clock source	clock { line [ primary ] internal }
Cancel clock source	no clock
Configure framing mode	framing { crc4 no-crc4 }
Configure line coding mode	linecode { ami hdb3 }
Start loopback test	loopback
Disable loopback test	no loopback
Create PRI group	pri-group [ timeslots timeslots-list]
Delete the specified PRI group	no pri-group
Enter the corresponding serial port of channel-group	interface serial serial-no :channel-group-no
Enter the corresponding serial port of ISDN PRI group	interface serial serial-no :15

By default, no channel-group(i.e. the system has not created channel-group for the time slots initially.) command becomes effective, and no loopback (i.e. disable loopback test) command becomes effective, and no pri-group(i.e. the system does not create any PRI group initially.) command becomes effective.

The default value of configuration command clock (clock source) is line, and framing (framing mode) no-crc4, and linecode (line coding mode) hdb3.
