Interconnect Port Networks with Fiber Optic Cabling
Collocated Port Networks
For a standard reliability system with 1 collocated EPN, use 1 fiber optic cable and
2 lightwave transceivers to directly connect the networks.
For a standard reliability system with 2 collocated EPNs, use 3 fiber optic cables
and 6 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 PNs.
For collocated cabinets, route the fiber optic cables directly from the PPN to each
EPN cabinet. Because 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 standard reliability system with 1 fiber-remoted EPN, use 2 fiber optic
cables, 2 lightwave transceivers, and 2 lightguide interface units (provided by the
PSC).
For a standard reliability system with 2 fiber-remoted EPNs, use 6 fiber optic
cables, 6 lightwave transceivers, and 6 lightguide interface units (provided by the
PSC).
DS1 CONV-Remoted Port Networks
For a standard reliability system with 1 DS1 CONV-remoted EPN, use 2 DS1
CONV circuit packs (TN1654), 2 DS1 Conv-to-EI cables (846448637 and/or
846448645), two H-600-348 cables, from 1 to 4 pairs of Channel Service Units
(CSUs), and from 1 to 4 pairs of MDF cables (provided with the CSUs).
NOTE:
The TN1654 requires the use of a TN573B Switched Node Interface circuit
pack
For a standard reliability system with 2 DS1 CONV-remoted EPNs, this
arrangement requires:
6 DS1 CONV circuit packs (TN1654)
6 DS1 CONV-to-EI cables (846448637 and/or 846448645)
6 H600-348 cables
3, 6, 9, or 12 pairs of CSUs
