channel-group channel-group timeslots { number | number1-number2 } [，number | number1-number2 …… ]
　
no channel-group channel-group
　
「Cold parameter description 」
　
Channel-group CE1/PRI for it on the interface index number of the new interface, range 0 ~ 30.
　
The specified binding time slot, you can specify a single time slot number, you can also specify the time range number1-number2, number as a time slot number in the range 1 to 31.
　
「Cold default 」
　
Do not bundle any channel-group.
　
「Cold command mode 」
　
CE1/PRI interface configuration mode
　
「Cold Guide 」
　
CE1/PRI interface physically divided into 31 time slot, the corresponding number of 0 ~ 30, you can arbitrarily divided into time slots are all groups of the time slot after as a bundled (channel-group) using the interface, its logical characteristics and the same synchronous serial interface, support for PPP, frame relay, X.25 LAPB and link layer protocols, such as support for IP and IPX network protocol.
　
No channel-group command to cancel the corresponding slot bundle.
　
「Cold example 」
　
The E1 interfaces 1, 2, 5, 10-15 and 18 slot bundle for no.1 channel-group.
　
Quidway（config-if-e0）#channel-group 1 timeslots 1，2，5，10-15，18
　
「Cold related command 」
　
pri-group
　
2.3.2 clock
　
CE1/PRI interface set in clock mode.
　
clock { DCE | lineclock }
　
no clock
　
「Cold default 」
　
CE1/PRI interface default clock mode to DTE way (lineclock).
　
「Cold command mode 」
　
CE1/PRI interface configuration mode
　
「Cold Guide 」
　
When CE1/PRI when used as a synchronous interface, DTE and DCE also has two working mode, also select the lines clock. When two router CE1/PRI interfaces are connected directly, you must enable both work at DTE respectively and DCE; when router CE1/PRI interfaces and switch, the switch to the DCE, and router CE1/PRI interface needswork in DTE way (lineclock). No clock command to restore the default clock mode.
　
「Cold example 」
　
CE1/PRI interface to set the clock for the DCE.
　
Quidway（config-if-e0）#clock DCE
　
「Cold related command 」
　
channel-group，pri-group
　
2.3.3 framing
　
Set CE1/PRI interface frame check.
　
framing { crc4 | no- 4 }
　
no framing
　
「Cold default 」
　
CE1/PRI interfaces default to not validate.
　
「Cold command mode 」
　
CE1/PRI interface configuration mode
　
「Cold Guide 」
　
CE1/PRI interface support on the physical frame of 4-byte CRC checksum, restore the default no framing command does not validate.
　
「Cold example 」
　
CE1/PRI interface set on physical frame for a 4-byte CRC.
　
Quidway（config-if-e0）#framing crc4
　
2.3.4 linecode
　
CE1/PRI interface set of line decoding format. linecode { ami | hdb3 }
　
no linecode
　
「Cold default 」
　
CE1/PRI interface default codec format is HDB3 format.
　
「Cold command mode 」
　
CE1/PRI interface configuration mode
　
「Cold Guide 」
　
No linecode command rehabilitation default codec format.
　
「Cold example 」
　
CE1/PRI interface settings of the default codec format for AMI format.
　
Quidway#（config-if-E0）#linecode ami
　
2.3.5 loopback
　
Allow or disallow CE1/PRI internal loop and external echo.
　
[ no ] loopback
　
「Cold default 」
　
Prohibit CE1/PRI interfaces internal loop and external echo.
　
「Cold command mode 」
　
CE1/PRI interface configuration mode
　
「Cold Guide 」
　
Only in some special functionality testing, only CE1/PRI interface is set to on from the Central and external echo. 「Cold example 」
　
Allow CE1/PRI interface e0 internal loop and external echo.
　
Quidway（config-if-e0）#loopback
　
2.3.6 pri-group
　
CE1/PRI interfaces to be slotted bundle for pri-group.
　
pri-group [ timeslots { number | number1-number2 } [，number | number1-number2 …… ] ]
　
no pri-group
　
「Cold parameter description 」
　
Bundled time slot, you can specify a single time slot number, you can also specify the time range number1-number2.
　
Note: due to the time slot 16 channel used to transmit D as signalling, cannot be used as a binding time slot.
　
「Cold default 」
　
The default is not to create PRI bundle.
　
「Cold command mode 」
　
CE1/PRI interface configuration mode
　
「Cold Guide 」
　
CE1/PRI interface can only be used to generate a bundled, its logical pri-group characteristics and ISDN dial-up port, supporting PPP link layer protocols that support both IP and IPX network protocol, you can configure parameters such as DDR.
　
No pri-group cancel the corresponding slot bundle.
　
The index number of the fixed pri-group is 15.
　
「Cold example 」
　
Will CE1/PRI interfaces 1, 2, 8-12, timeslot bundle for pri-group.
　
Quidway（config-if-E0）#pri-group timeslots 1，2，8-12
　
「Cold related command 」
　
channel-group
