VOIP Ready Pulse to Tone Conversions - inDAT & inDAT300.
£50.00
We are proud to be extending our VOIP provision with our own 'inDAT' Pulse to Tone Converter. Designed to fit inside a telephone the inDAT is a variant of our market leading 'Dial-A-Tone' or DAT - hence the name 'inDAT'. This is becoming a very popular service, but we aim for a turnaround time under 7 days. Please contact us for current wait times.
Like the Dial-A-Tone, the inDAT is a line powered device which operates almost silently and is designed to function with all domestic VOIP systems. We also have our inDAT300, which is designed specifically for 300 series telephones.
We will fit an inDAT or inDAT300 to your vintage dial telephone to give you tone dialling and, if you require, 'Star', 'Hash', 'Last Number Redial' and up to seven stored numbers. These options are switchable so the product can quickly be customised to your needs.
Our fitting service relates to pulse to tone conversion, and not other restoration or conversion work. If you would like to discuss additional work, please drop us a message or call on 07305 312299.
The postage in this listing is Royal Mail Tracked 24 which is insured to £150. If you require a higher level of insurance, please contact us and we will invoice accordingly. By purchasing as listed you are accepting the insurance level of £150.
...and a little more background
The inDAT is another ‘Vintage Telephony’ product which we have designed because we were not happy with the quality and performance of other products on the market.
Developed exclusively for us by Geoff Peters, the inDAT family are internal pulse to tone converters designed to function on VOIP lines (BT Digital Voice, Sky etc) and, importantly, are near silent in operation.
Because we know a lot of our customers like vintage telephones to be kept as original as possible, our inDAT can operate in one of three modes.
1) Pulse to tone conversion only – dialling 0-9.
2) Pulse to tone conversion, 'Star' & 'Hash'.
3) Pulse to tone conversion, 'Star & Hash', 'Last Number Redial' & Stored Numbers.
Our inDAT & inDAT300 is fitted internally. It is a single unit and requires no addition components.
Technical Notes:
The inDAT has full bridge rectification to protect against reverse line polarity. It needs 24mA to operate which is matched or exceeded by all common VOIP services.
It has a balancing circuit to work with most types of microphone - carbon or electronic.
Once a dialled digit has been detected, the circuit will send out a corresponding tone burst to line using DTMF4 encoding. To solve the noise issue we have a muting device to attenuate the tone to an almost inaudible level.
Because of the current draw, the inDAT cannot be used in a circuit that has a Dial-A-Tone before it in the circuit. Rearranging the order of connection will resolve the issue.
Note: Because of variance across the new VOIP market, we supply all inDAT installations with a BT to BT ring capacitor adaptor. This will allow telephones to ring in VOIP connections that do not have a ring capacitor, but should not be used unless required. Please contact us and we will explain – it’s very straightforward!
