ABLING
:
For connecting a standard telephone set to the system the wires of the cable
coming from the corresponding extension connector on MB48 motherboard or
EXP48 card and passing 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)
must be attached to the A / B terminals of the telephone.
For connecting an external line to the system the wires of the cable coming from
the corresponding line connector on MB48 motherboard or EXP48 card and
passing 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) must be
attached to the external line.
Figure B-30
Normally a standard telephone set can be connected as much as 2 kms away
from the system by using ordinary copper wires. Depending on the quality of the
wires the distance changes proportionally.
