Install Circuit Packs
1. Install the new Release 8 control circuit p acks into carrier “A.” Use the
new label and the annotated “list configuration all” (provided with the
Release 8 removable media) as a guid e.
NOTE:
Currently, the TN768 Tone-Clock circuit p ack resides in a port slot of
the universal module being upgraded. Reloc ate this circuit pac k to
the “TONE CLOCK” slot of carrier “A.” Lucent Technologies
recommends upgr ading to the TN2182 Tone-Clock.
2. Install circuit pac k blanks in slots not equipp ed with circuit p acks.
3. For a directly-connected standard reliability Release 8 system wi th 2 port
networks, ensure the PPN and this EPN are both equipped with a TN776
or TN570 Expansion Interface circuit p ack.
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 cab ling terminated to 9823A lig htwave transceivers can interc onnect
PNs up to 4,900 feet (1493 m) apart. Fiber op tic cabling terminated to 9823B
lightwave transceivers can interconnect PNs up to 25,000 feet (7620 m) ap art.
The 300A fiber optic lightwave transc eiver can interconnect PNs up to
115,000 feet (21.7 miles, 35 km) apart.
NOTE:
These distance limits are app roximate measurements of the
actual
fiber
right-of-way (not of the shortest linear d istance) between the 2 endp oints.
NOTE:
It is important to label ever y cable that you install.
NOTE:
Keep track of which fib er attaches to which c onnector on each lightwave
transceiver. This section provid es figures offering sugg ested ways of
making these connections .
The connectors on the lightwave transc eivers are labeled either “ TX”
(transmit) or “RX” (receive), while the fibers attach ing to each connec tor are
numbered either “1” or “2.” A viable fib er connection is only mad e when
both fibers in each c able (“1” and “2”) route from the “TX” connec tor of a
port network to the “RX” connec tor of its adjacent por t network. See Figure
5-6.
NOTE:
When finished, refer to Appendix A, ‘‘Fiber Link Administration’’ to
administer the fiber links.
