new EQUIPMENT
OF Old Kentucky Telephone and
Telegraph Company.
OF INTEREST TO SUBSCRIBERS.

on which the Old Kentucky Tele-
phone & Telegraph Co. has begun
work, an entire new exchange
equipment will be installed in the
new Burroughs building designed
for the purpose, located on High
street. The switchboard will be
the best that can be bought. 1t is
being made by the Stromberg-
Carlson Telephone Manufacturing
Company, of Rochester, n. Y. The
multiple board on which subscriber
lines terminate will have one toll
position and five local operator po-
sitions. There will be installed 20
toll lines and $50 subscriber lines.
Every subscribers line will have
separate terminal within the reach
of every operator so that when
any one calls central the operator
answering can make the connection
to any one Of the $50 lines. While
the switchboard has only $50 lines
installed, it has an ultimate capac-
ity of 1900 lines and new section
of 800 lines each can be added as
the business grows.
Besides the main board there
will be a chief operators desk and
wire chiefs desk. a State switch
board for the storage battery, and
a power switchboard associated
with the storage battery, dynamo
and gas engine.
When a subscriber rings central
a white signal shows on the face of
the board and at the same time
a white lamp is lighted directly in
front of the operator and a white
light numbered to correspond to
the position of that operator is
lighted on the chief operators
desk. Both of these lights con-
tinue to burn until the call is ans
wered. When a connection is
made between two subscribers
there is a separate ring-off signal
associated with each of pair of
cards so that the operator can tell
which of the two people connected
is ringing for another connection
and the card circuit is so designed
that one subscriber cannot ring
through and ring the other sub
scriber's bell. When either of
these ring-off signals is thrown a
red light is lighted in front of the
operator and q corresponding red
light burns on the chief operators
desk. These lights continue to
burn until the connection is taken
down.
The chief operator has on her
desk one of these white lamps and
one red one and one secret listen
ing button and one talking button
associated with each operator on
the main board. She can tell by
the length of time the lamps stay
lighted how long it takes an opera
tor to answer a call or disconnect
line. She can listen in on any of
the operators without their know
inc it and correct or help them in
their work. She will have COM
plete card indexes in her desk with
the exact address of all subscribers.
The wire chief desk will be To-
Gated in the cable terminal room.
1t will be equipped with the latest
apparatus for testing lines and To-
eating faults.
All lines, except the toll lines,
will be brought into the exchange
in four cables, each containing 404
wires.
There will be altogether $500
feet of lead-covered cable used and
it will vary in size from 20 pairs of
wires to 200 pairs. The cables will
be suspended from steel ropes that
are stretched taut on the poles and
anchored at each end to galvanized
steel rods fastened to locust logs
buried in the ground.
The cables will have terminals
on the poles that will vary in size
