DT Etherlink IV
User Manual

Two rules: The list of priority clock sources should contain only those E1 channels, which are used
to transmit data over the SHDSL channel. If the SHDSL channel does not transmit any E1 streams,
it is possible to set any of the E1 channel as a reference clock source or to use the external clock.
Note:
If the list of the E1 channels transmitted over DSL is changed by the PAYLOAD
command, it can change the list so that it corresponds to the previous two criteria.
CO_CM>SETCLOCK EXT,E1-1,E1-2
CO_CM>SETCLOCK INT
4.6.5.11 <MULTIPAIR [2/3/4/2+2/OFF]> Command
This command activates the multipair mode, which allows to merge DSL channels.
Groups of 2, 3 and 4 channels can be merged into the multipair mode. The following variants are
possible:
CO_CM>MULTIPAIR 2
CO_CM>MULTIPAIR 3
CO_CM>MULTIPAIR 4
CO_CM>MULTIPAIR 2+2
4.6.5.12 <RESERVE [list]>, <RESERVE [list] [list]> Command
This command allows combining SHDSL channels into groups in order to reserve them. Not more
than 2 groups are possible in a system with 4 SHDSL channels. The reservation groups are called A
and B groups. The parameter sets the list of channel numbers separated by a comma. To simplify
configuration and maintenance of devices, any groups of successive channels can be reserved. To
configure the reserve group, type the following command:
CO_CM>RESERVE 1,2
To configure two reserve groups type the command as follows. Note that groups should not use
same channels.
CO_CM>RESERVE 1,2 3,4
The parameter NONE deactivates reservation.
CO_CM>RESERVE NONE
4.6.5.13 <G704 ON/OFF [N]> Command
This command activates/deactivates the ITU-
T G.704 framed mode for the Е1 interface with number
N.
The <G704 ON 1> activates the ITU-T G.704 framed mode. The <G704 OFF 1> deactivates the
ITU-T G.704 framed mode, i.e., the devices starts operating in the so-called transparent mode.
CO_CM>G704 ON 1
4.6.5.14 <CRC4 ON/OFF [N]> Command
This command activates/deactivates the CRC4 mode for the E1 channels, where N is the number of
the E1 channel.
CO_CM>CRC4 ON 1
4.6.5.15 <AISGEN ON/OFF [N]>, <AISDET ON/OFF [N]> Commands
The
<AISGEN ON/OFF [N]>
command activates/deactivates the AIS Generation mode for the E1
interface, where N is the number of the E1 interface.
The
<AISDET ON/OFF [N]>
command activates/deactivates the AIS Detection mode for the E1
interface, where N is the number of the E1 interface.
CO_CM>AISGEN ON 1
CO_CM>AISDET ON 1
