WARNING:
Unterminated optical connectors may emit invisible laser
radiation. Avoid direct exposure to the beam. Do not view
beam with optical instruments. Use of controls or
adjustments or performance of procedures other than those
specified herein may result in hazardous radiation exposure.
!
CAUTION:
DDM-2000 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:
If the DDM-2000 fails to respond in the indicated manner,
refer to Trouble Clearing: IXL-001.
NOTE:
It is assumed that all DDM-2000 OC-3 shelves in the system
have passed the looped transmission test(s). [System
Turnup: NTP-016] and the host DDM-2000 OC-3 or OC-12
ring has been established [System Turnup: NTP-022] with
software to support DDM-2000 FiberReach applications. It is
also assumed the DDM-2000 FiberReach shelf(ves) has
been equipped and tested using DDM-2000 FiberReach
documentation (363-206-305, DDM-2000 FiberReach
Multiplexer, Wideband/Narrowband Shelf, TARP Release 3
and Later, User/Service Manual, System Turnup:
NTP-007).
Determine the network configuration (for example, see Figures 1,
2, 3, and 4.)
