of the xDSL stream (57*64 = 3648 kbit/sec) will be used to transmit WAN (Ethernet) by the
<PAYLOAD E1-1, WAN> command.
For modems with one xDSL channel, the command is as follows:
CO_CM>PAYLOAD WAN
CO_CM>PAYLOAD E11,WAN
CO_CM>PAYLOAD NONE
4.6.5.9 <ANNEX A/B/AB [N=1..4]> command
The <ANNEX A/B [N=1..4]> command enables the transmission standard: G.991.2 ANNEX A or
G.991.2 ANNEX B, where N is the number of the interface.
The <ANNEX AB> automatically selects the transmission standard.
Note:
If devices use different transmission standards, synchronization will not be
established between them.
4.6.5.10 <SETCLOCK list [N=1..4]> command
The <SETCLOCK list [N=1..4]> command sets the priority list of clock sources for the xDSL
channel, where N is the number of the xDSL channel. The possible clock sources are:
• External sync source. Marked as EXT, EXTERNAL (only for Sub-Rack modems);
• first E1 channel. Marked as 1, E11, E1-1, E1_1;
• second E2 channel. Marked as 1, E12, E1-2, E1_2;
• internal sync source. Marked as INT, INTERNAL.
The external clock source should be either the first one in the priority list or be not used at all.
The next clock sources in the list should be E1 channels. The internal clock source should be
the last one in the priority list. It is not necessary to type it in the command.
The parameter N can be absent for single-channel modems.
The list of priority clock sources should contain only those E1 channels, which are used to
transmit data over the xDSL channel.
If the xDSL channel is not used to transmit E1 streams, it is possible to set any of the E1
channel as a reference clock source or to use the external (EXTERNAL) clock.
Note: If the list of E1 channels transmitted over DSL is changed by the PAYLOAD command,
this command can change the list so that it corresponds to the previous two criteria.
For example:
CO_09_CM>SETCLOCK EXT,E1-1,E1-2
CO_CM>SETCLOCK INT
4.6.5.11 <MULTIPAIR [MODE]> command
The <MULTIPAIR> command activates multipair mode, which allows one to merge DSL
channels.
Groups of 2, 3 and 4 channels can be merged in the multipair mode. The following variants are
possible:
CO_01_CM>MULTIPAIR 2
CO_01_CM>MULTIPAIR 3
CO_01_CM>MULTIPAIR 4
