DT Etherlink IV User Manual- 70 -Two rules: The list of priority clock sources should contain only those E1 channels, which are usedto 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 PAYLOADcommand, it can change the list so that it corresponds to the previous two criteria.CO_CM>SETCLOCK EXT,E1-1,E1-2CO_CM>SETCLOCK INT4.6.5.11 CommandThis 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 arepossible:CO_CM>MULTIPAIR 2CO_CM>MULTIPAIR 3CO_CM>MULTIPAIR 4CO_CM>MULTIPAIR 2+24.6.5.12 , CommandThis command allows combining SHDSL channels into groups in order to reserve them. Not morethan 2 groups are possible in a system with 4 SHDSL channels. The reservation groups are called Aand B groups. The parameter sets the list of channel numbers separated by a comma. To simplifyconfiguration and maintenance of devices, any groups of successive channels can be reserved. Toconfigure the reserve group, type the following command:CO_CM>RESERVE 1,2To configure two reserve groups type the command as follows. Note that groups should not usesame channels.CO_CM>RESERVE 1,2 3,4The parameter NONE deactivates reservation.CO_CM>RESERVE NONE4.6.5.13 CommandThis command activates/deactivates the ITU-T G.704 framed mode for the Е1 interface with numberN. The activates the ITU-T G.704 framed mode. The deactivates theITU-T G.704 framed mode, i.e., the devices starts operating in the so-called transparent mode.CO_CM>G704 ON 14.6.5.14 CommandThis command activates/deactivates the CRC4 mode for the E1 channels, where N is the number ofthe E1 channel.CO_CM>CRC4 ON 14.6.5.15 , CommandsThe command activates/deactivates the AIS Generation mode for the E1interface, where N is the number of the E1 interface.The ON/OFF [N]> command activates/deactivates the AIS Detection mode for the E1interface, where N is the number of the E1 interface.CO_CM>AISGEN ON 1CO_CM>AISDET ON 1
