DS1 CONV Cabling to the Public Network. Use the running list that
accompanies the up grade equip ment to determine which c able connects where.
The following paragraphs only provide concep tual information about wiring a
DS1 CONV interface to a wall-field block, not step -by-step proc edures for wiring
a specific Release 8r system.
If already connected to either an expansion or switch nod e interface, a DS1
CONV circuit pack alread y resides either in an EPN expansion control carrier o r
in a PPN port carrier or switch nod e carrier.
Depending on the traffic requirements between the 2 port networks, a 25-foot
(7.625 m) H600-348 cable extend s from the piggy-bac k connector (on each DS1
CONV-to-EI/SNI cable) to from 1 to 4 CSUs. This cable branches to four 15-p in
subminiature D-type connec tors (labeled “01” to “04”) to make the CSU
connections. Then, in turn, the CSUs connec t to the wall-field block
(corresponding to th e equipment location of the DS1 CONV) at port c onnections
“8,” “7,” “6,” and “5” (in descending order).
Neglecting overhead , this wiring arrangement c an provide PN-to-PN
communication at the band width of up to 4 DS1 CONV spans (1.544 Mb ps
each). Between each por t network’s wall field, the port networks c ommunicate
across leased lines in the pub lic network.
Connect Power and Ground
1. Reconnect the 6 AWG (#40) (4.1 mm2) cabinet ground wire to the
single-point ground bar on the cabinet.
2. Reconnect the 10 AWG (#25) (2.6 mm2) coupled bonding c onductor wire.
3. Reconnect the cabinet p ower cords at the rear of each c abinet.
