Establish Dual-Homed OC-3 or OC-12 Access
via FT-2000 OC-48 Backbone Ring

!
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 FT-2000 shelves in the system have
passed local tests and the FT-2000 ring has been
established. It is also assumed the DDM-2000 OC-3 shelves
have been equipped and tested (363-206-285, DDM-2000
OC-3 Multiplexer, TARP Release 13 and Later, User/Service
Manual (TOP)—Volume II , System Turnup: NTP-016).
NOTE:
This procedure is used to establish a dual-homed DDM-2000
OC-3 or OC-12 ring connection to an FT-2000 ring (See
Figure 1). Other configurations may have to be established
to obtain your final configuration. See NTP-047 for
single-homed configurations and NTP-049 for single OC-3
optical extensions from the FT-2000 low speed interface (LS
INTFC) ports.
Determine the network configuration (for example, see Figure 1.)
