We continue with our configuration example. Time slots 0 to 15 of E1 interface 1 are assigned to
DSL loop A, time slots 16 to 31 to loop B. If we assume a line rate of 2064kbit/s for loops A and
B, we can carry 32 time slots on both loops. However, we only have 16 time slots assigned to
each DSL loop, thus we have to select which of the available 32 time slots will ‘carry’ the 16 E1
time slots. To use time slots 0 to 15 on loop A and time slots 1 to 16 on loop B, use these
commands.

The ‘MP’ command is used with the first parameter ‘A’ for loop A and ‘B’ for loop B. The second
parameter contains 32 characters, which are assigned to the 32 time slots on the DSL loops. The
string can contain the numbers 0 to 2:
0: time slot is not used (send/receive all ones),
1 or 2: the next time slot from E1 interface 1 or 2 is sent and received in this DSL time slot.
The order of the time slots on the DSL loop is the same as in the E1 frame. In our example time
slot 0 from E1 interface 1 is the first time slot assigned to loop A. It will be transmitted on the
first time slot in DSL loop A whose character is ‘1’. The second time slot assigned to loop A (E1
time slot 1) will be assigned to the second time slot in DSL loop A whose character is ‘1’, and so
on.
If the second parameter has less than 32 characters, the remaining time slots are unused, so
you can use “MP B 01111111111111111” instead of
“MP B 01111111111111111000000000000000”. To switch off all time slots, “OFF” can be used
as the second parameter.
