Table 3-5 lists the cable numbers and lengths for the possible connections.
DS1 CONV Cabling to the Public Network.
Use the running list that
accompanies the upgrade equipment to determine which cable connects where.
The following paragraphs only provide conceptual information about wiring a
DS1 CONV interface to a wall-field block, not step-by-step procedures for wiring
a specific Release 8r system.
If already connected to either an expansion or switch node interface, a DS1
CONV circuit pack already resides either in an EPN expansion control carrier or
in a PPN port carrier or switch node carrier.
Depending on the traffic requirements between the 2 port networks, a 25-foot
(7.625 m) H600-348 cable extends from the piggy-back connector (on each DS1
CONV-to-EI/SNI cable) to from 1 to 4 CSUs. This cable branches to four 15-pin
subminiature D-type connectors (labeled “01” to “04”) to make the CSU
connections. Then, in turn, the CSUs connect to the wall-field block
(corresponding to the equipment location of the DS1 CONV) at port connections
“8,” “7,” “6,” and “5” (in descending order).
Neglecting overhead, this wiring arrangement can provide PN-to-PN
communication at the bandwidth of up to 4 DS1 CONV spans (1.544 Mbps
each). Between each port network’s wall field, the port networks communicate
across leased lines in the public network.
Connect Power and Ground
1. Reconnect the 6 AWG (#40) (4.1 mm
2
) cabinet ground wire to the
single-point ground bar on the cabinet.
2. Reconnect the 10 AWG (#25) (2.6 mm
2
) coupled bonding conductor wire.
3. Reconnect the cabinet power cords at the rear of each cabinet.
