CAUTION:
Take care to avoid damaging the LEDs that protrude through the opening
in the faceplate of the
DS3
circuit pack.
NOTE:
DS3 circuit packs are installed in Function Units Group slots, FN-1 and
FN-2. BBG4/BBG4B DS3 service circuit packs are installed in slot FN-1.
BBG4/BBG4B DS3 protection circuit packs are installed in slot FN-2.
BBG19 DS3 data interface circuit packs are installed in FN-1 and FN-2
slots and are independent. There is no protection between the BBG19
DS3 circuit packs.
Determine which Function Units Group slot(s) FN-1 and/or FN-2 is being
equipped with DS3 circuit packs.
2. Determine from office records the length of the DS3 cabling between the
DDM-2000 and the DSX-3 cross-connect point.
3.
NOTE:
The only hardware option settings on DS3 circuit packs are the LBO
settings shown in Figure 1. If there are other jumpers on the circuit pack
similar to the LBO jumpers, they are factory test points and should be
ignored.
Refer to Table A and Figure 1. Install the DS3 option jumpers per Table A.
