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 the DDM-2000 FiberReach shelves have been
equipped and tested (System Turnup: NTP-007). It is also
assumed that all DDM-2000 OC-3 shelves in the system
have passed the looped transmission test(s) and the
DDM-2000 OC-3/OC-12 ring has been established
