Critical Reliability
NOTE:
Keep track of which fiber attaches to which connector on each lightwave
transceiver. This section provides figures showing typical ways of making
these connections.
The connectors on the lightwave transceivers are labeled TX (transmit) or RX
(receive), while the fibers attaching to each connector are numbered 1 or 2. See
Figure 4-16.
Collocated Port Networks
For a critical reliability system with 1 collocated expansion port network, use 2
fiber optic cables and 4 lightwave transceivers to directly connect the networks.
For a critical reliability system with 2 collocated expansion port networks, use 6
fiber optic cables and 12 lightwave transceivers to directly connect the networks.
NOTE:
Based on floor plan considerations, the length of these cables may vary.
20-foot (6.1 m) cables are normally adequate for 2 port networks.
For collocated cabinets, route the fiber optic cables directly from the PPN to each
EPN cabinet. Since a PPN cabinet is collocated with a Single-Carrier Cabinet
(SCC1) stack, the preferred routing is to run the cables down the cable tray and
out the bottom of the PPN cabinet. The cables are then run to the EPN cabinet
and up the outside of the rear panels to the desired carrier level.
Fiber-Remoted Port Networks
For a critical reliability system with 1 fiber-remoted EPN, use 4 fiber optic cables, 4
lightwave transceivers, and 4 lightguide interface units (provided by the PSC).
For a critical reliability system with 2 fiber-remoted EPN, use 12 fiber optic cables,
12 lightwave transceivers, and 12 lightguide interface units (provided by the PSC).
DS1 CONV-Remoted Port Networks
For a critical reliability system with 1 DS1 CONV-remoted EPN, this arrangement
requires:
Four DS1 CONV circuit packs (TN1654)
Four DS1 CONV-to-EI cables (847245750 and/or 847245768)
Four H-600-348 cables
Two, 4, 6, or 8 pairs of channel service units (CSUs)
