TELEPRINTER No. 60A
SABLE RECEIVE-ONLY TELEX TERMINAL
1 INTRODUCTION
This instruction describes the Teleprinter No. 60A known as the Sable,
its operation and the facilities that are available.
2 GENERAL DESCRIPTION
The Sable is an electronic microprocessor controlled receive-only
teleprinter for connection to the Telex network. Outgoing traffic cannot be
originated from this machine. The Sable is housed in a compact two tone grey
case and is quiet in operation. The cover of the teleprinter has .a. hinged
lid, giving easy access for paper and ribbon replacement, this lid
incorporates a window which makes the copy visible during message reception
and provides a cutting edge for message removal.
3 FACILITIES
The Sable operates at the normal Telex speed of 66 wpm. It can print up
to 69 characters or spaces on each line using standard teleprinter paper,
which can be single--ply or multiply paper giving up to 3 under-copies.
3.1 Printing Characters
The printed characters are formed by a 7 x 5 dot matrix needle printing
head, using a standard nylon ribbon. This method of printing, together with
the absence of a keyboard, allows a considerable reduction in size of the
machine and noise level.
3.2 Line Feed
Three line feed options are provided. Single, one and a half end double
spacing. They can be selected by means of a switch under the front left hand
side of the machine.
3.3 Operation On receiving a "who are you" signal from
the calling teleprinter
The Sable will respond by sending the pre-programmed answerback. Answerbacks
can be exchanged at the end of the message as in normal practice. Should the
caller attempt to set up a conversation by sending bell signals, the Sable
will send the new internationally agreed service signal e.i. which means
"communication impossible". The only control on the Sable is a clear key
which may be used to clear the Telex line should this be desired.
3.4 Messages
Messages can be received at all times provided the power is switched on and
there is an adequate supply of paper in the machine. The Sable switches on
and off automatically at the start and finish of any communication.
3.5 Power
Power for the teleprinter is drawn from a 3-pin mains socket outlet
of at least 3-amp rating, provided by the user.
3.6 Placement
The Sable can be used free standing on customers tables or, for an
additional charge, a black plinth is available as an optional extra.
4 SELLING BENEFITS A summary of the main selling
benefits of the Sable are listed below:-
-
Because of its compact size and quiet operation the
teleprinter is ideal in a normal office environment.
-
Being a receive-only teleprinter
without a keyboard, trained operating staff are not required.
-
If message switchers are used, and automatic
switching facilities have been provided, the Sable could be used for
standby purposes to record incoming Telex messages should the message
switch develop a fault.
