CAUTION:
DDM-2000 FiberReach circuit packs contain static sensitive
components which can be damaged by electrostatic
discharge. A static ground wrist strap must be worn when
handling the circuit packs. See electrostatic discharge
considerations in
Trouble Clearing: TAD-100.
NOTE:
This procedure assumes that a new DS1 port or
DS1/DS1PM circuit pack is being added to a DDM-2000
FiberReach shelf that is already in service. It also assumes
that STS1E circuit packs have been installed if the other end
is an EC-1 interface.
NOTE:
For the 1X1 protection configuration, circuit packs are
protected on a one-to-one basis. For example, if protection
is required for a DS1 circuit pack in a service LS-[A-1, B-1,
C-1, or D-1] slot, a DS1 circuit pack must be installed in the
protection LS-[A-2, B-2, C-2, or D-2] slot. If BBF3 DS1PM
circuit packs are installed in service slots, then a BBF3
DS1PM circuit pack must be installed in the protection slot if
protection is required.
NOTE:
For the 1X7 protection configuration, the circuit pack type
installed in the LS-D-2 slot is the only circuit pack type that is
protected. In a 1X7 protection configuration, 177A
Apparatus Blank cards are required in unequipped
LOW-SPEED slots.
