Install Circuit Packs
1. Install the new Release 8 control circuit packs into carrier “A.” Use the
new label and the annotated “list configuration all” (provided with the
Release 8 removable media) as a guide.

NOTE:
Currently, the TN768 Tone-Clock circuit pack resides in a port slot of
the universal module being upgraded. Relocate this circuit pack to
the “TONE CLOCK” slot of carrier “A.” Lucent Technologies
recommends upgrading to the TN2182 Tone-Clock.

2. Install circuit pack blanks in slots not equipped with circuit packs.
3. For a directly-connected standard reliability Release 8 system with 2 port
networks, ensure the PPN and this EPN are both equipped with a TN776
or TN570 Expansion Interface circuit pack.

For a directly-connected system with 3 port networks, ensure the PPN and
each EPN have two TN776 or TN570 circuit packs.

Interconnect Port Networks
Fiber optic cabling terminated to 9823A lightwave transceivers can interconnect
PNs up to 4,900 feet (1493 m) apart. Fiber optic cabling terminated to 9823B
lightwave transceivers can interconnect PNs up to 25,000 feet (7620 m) apart.
The 300A fiber optic lightwave transceiver can interconnect PNs up to
115,000 feet (21.7 miles, 35 km) apart.

NOTE:
These distance limits are approximate measurements of the
actual fiber
right-of-way (not of the shortest linear distance) between the 2 endpoints.
NOTE:
It is important to label every cable that you install.
NOTE:
Keep track of which fiber attaches to which connector on each lightwave
transceiver. This section provides figures offering suggested ways of
making these connections.
transceiver. This section provides figures offering suggested ways of
making these connections.
The connectors on the lightwave transceivers are labeled either “TX”
(transmit) or “RX” (receive), while the fibers attaching to each connector are
numbered either “1” or “2.” A viable fiber connection is only made when
both fibers in each cable (“1” and “2”) route from the “TX” connector of a
port network to the “RX” connector of its adjacent port network. See
