Configuring Framed or Unframed Operation
(DSX-1-to-DSX-1 Configuration)
In Switchpack Mode, specify Unframed operation by setting switches 3 – 7 on
switchpack S4 to OFF.
Configuring a Starting Time Slot (DSX-1-to-V.35/V.11 Configuration)
In Switchpack Mode, switches 3 – 7 on switchpack S4 determine the starting time
slot, as shown in
Table C-1
on page C-2.
If the payload rate (configured on the V.35/V.11-compatible unit) is 1544 kbps, set
switches 3 – 7 all to the OFF position. This is the factory default.
If the payload rate is
less than 1544 kbps, use switches 3 – 7 to select a starting
time slot (DS0). Make sure that there are enough subsequent time slots to
accommodate the V.35/V.11 payload rate (refer to the Maximum Payload Rate
column in
Table C-1
on page C-2). Contact your network administrator to verify
your starting time slot selection, as some time slots may already be in use.
