Working with
Time Slots
This section provides instructions for performing time slot configuration
from the front panel.
Reassigning All Time Slots between Data Channels/Sublink
If you want to reassign all timeslots from one data channel/sublink to
another data channel/sublink, you must close the data channel/sublink (free
all timeslots assigned to it), and then assign the timeslots to another data
channel/sublink.
1. If the data channel/sublink, which you want to close serves as master or
fallback clock source, you must select a different timing reference first.
Perform the selection by scrolling to SYSTEM PARAMETERS in the top
row and setting temporarily CLK MASTER to INT and CLK FBACK to
NONE.
2. Deactivate all loopback tests. For instructions on deactivating loopback
tests from the front panel, refer to Diagnostic Tests in Chapter 5.
3. To close a data channel, scroll to CHANNEL PRM CHX in the top row.
Set the SPEED parameter to NC and press the ENTER button.
4. To close the sublink, scroll to SL PARAMTERS in the top row. Set the
NUM OF TS parameter to NC and press the ENTER button.
5. To reassign the closed time slots to the sublink, scroll to SL PARAMTERS
in the top row and assign the time slots to the sublink. Refer to
Table 3-3 for instructions on assigning time slots to the sublink.
6. To reassign the closed time slots to a data channel, scroll to CHANNEL
PRM CHX in the top row and assign the time slots to the channel. Refer
to Table 3-4 for instructions on assigning time slots to data channels.
7. Select the new sources for the CLK MASTER and CLK FBACK
parameters.
Note
You must assign at least one timeslot to the data channel or sublink, which
you select as master or fallback clock source.
Reconfiguring Individual Time Slots
To reconfigure individual time slots, follow the steps below:
1. Deactivate all loopback tests. For instructions on deactivating loopback
tests from the front panel, refer to Diagnostic Tests in Chapter 5.
2. To reassign time slots currently assigned to a data channel, scroll to
CHANNEL PRM CHX in the top row. Set the SPEED parameter to the
corresponding (lower) value. To reassign time slots currently assigned to
the sublink, scroll to SL PARAMETERS in the top row. Set the NUM OF
TS parameter to the corresponding (lower) value. Select USER under
MAP MODE. For each time slot you want to reassign, scroll to the time
slot in the bottom row and set it to NC. When the closing of the desired
time slots is completed, press ENTER.
