Sales Brochure -
No. 108, sales name Tyne, has the capacity to store 50 telephone numbers with up to 18
digits, plus access digit and pause for PABX use, i.e. 20 digits, and dial them at the
press of one button. It is powered direct from a 9.5 volt ac Plug Top Transformer with a
72 hour memory back up battery charged from the transformer. The Tyne is supplied set for
Loop Disconnect dialling, but may be changed by an engineer on site to MF4 signalling by
opening the unit and altering the slide switch on the PCB and moving a wire link from
terminal NC (Normally Connected - terminal not marked) to NO (Normally Open). The switch is
located between the two PCB's at the cord entry end of the unit, is visible and easily
The wire link (LK2) provides a loop disconnect pulse shaping and bell shunt when set to NC
(Normally Connected), and removes this network when moved to NO (Normally Open) to stop
tone distortion and attenuation when MF4 signalling is used.
The second link, marked 70/140 indicates the duration of each MF tone in ms. The normal
setting is 70, but occasionally, on old type equipment, it may require setting to 140.
To make an outgoing call from Tyne, the telephone handset must be lifted, dial tone
received before pressing the required address memory button.
The Autodial 5000 is an Autodial No. 108C (Tyne) with the internal link set to NO (Normally
Open) although the slide switch is set for Loop Disconnect pulsing. The Autodial 5000 is
approved as issued for use on Ambassador and Senator systems.
If necessary, an Autodial 5000 may be restored to an Autodial No. 108C by removing the base
and returning the plug ended wire link to NC (Normally Connected). Any other signalling
changes are made as for the No. 108 detailed above.
All four autodials were supplied in Ambassador style cases coloured Stone, Grey and Brown.
All the above products have now been withdrawn from the BT portfolio, but the existing
base is expected to remain in situ for several years to come.

When originally introduced in 1983, it was considered the main use of the autodiallers
would be as an attachment to PABX extensions. For this reason, the user guide in all cases
refers to the autodiallers as having 18 store memories and not 20. The reason for
marketing in this manner, was that after the customer has entered the PABX access digit
and Pause, they then have 18 usable digits to programme into any memory store.
A unit that displays the symptoms of sending wrong numbers and unable to program is
usually caused by a faulty battery.

The callmaker will then dial the complete number, including for PABX's the access digit
