OC-3 low-speed LNW45 or LNW55 PTM testing procedure
Perform the following steps for all Alcatel-Lucent 1665 DMXtend shelf function unit or
growth slots containing LNW45 (OC3) or LNW55 (with 12 OC3 PTMs) OLIU circuit
packs.
Note:
main slots to operate in a Alcatel-Lucent 1665 DMXtend shelf.
Note:
on the OLIU, make the connections at the LGX equipment in order to verify correct
installation and labeling of the fibers.
Note:
associated fibers, then move PTMs to ports that are fibered.
LBOs are installed on the OLIU faceplate IN port.
