Figure B-9
To make the cabling of each LT48(-H) Feature Phone, OP48(-H) Console and
DSS40 / DSS80 Direct Station Select Module :
1) The free end of the system data cable must be passed through the hole on
the panel at the down left corner of the system cabinet (the panel on which
the system ON/OFF switch resides) and then attached to the CONSOLE
connector on SPS48 card.
2) The Data / + 12 VDC / GND signals on the connection box of the system
data cable must be wired in parallel to the corresponding pins of the
connection box of the telephone data cable.
3) The RJ plug at the free end of the telephone data cable must be inserted
into the female correspondant on the telephone or DSS module.
4) At this point, the cabling of DSS40 and DSS80 modules is completed, as
there are no A / B terminals for these modules. However, for each
OP48(-H) and LT48(-H) telephone, the wiring of the A / B terminals must be
made separately, by connecting the wires of the cable coming from the
corresponding extension connector on MB48 motherboard or EXP48 card
to the A / B terminals (the terminals with red and green wires) in the
connection box of the telephone data cable.
The following figure illustrate the cabling of OP48(-H) Consoles, LT48(-H)
Feature Phones and DSS40 / DSS80 Direct Station Select Modules.
