Integrated Telephone Data logging (ITDL) System
Lanka N. Bogoda
Domestic and Business telephone users in Sri Lanka are not
provided with a detailed listing of outgoing telephone calls. The detailed
listing is very important owing to the fact of rising telephone call charges and
in turn an additional burden on subscriber.
By using ITDL subscribers can formulate their own telephone
management criteria in order to minimize call duration and unnecessary calls.
This is because the call charges are varying depending on time a call started
and the number of unit consumed. In addition, a subscriber can locate any
unauthorized calls originated by the telephone in the absence of
him or her.
ITDL has a storing capacity of around 600 telephone calls.
For domestic use this is normally the usage of two months and for office usage
it is advisable to take print outs each month and reset the system to leave room
for storing more call information.
Subscriber can easily plug in ITDL to his telephone and to
main power. The system has a very simple operating system. Further, it can run
as a stand along system, even in the absence of main power. It needs little
maintenance. ITDL can be kept alongside the telephone or else in a place, which
are cool, dry and dust free.
The report covers most of the design that I thought vital
to be documented. It starts with a project overview to its main components and
highlights the design approach. The subsequent sections explain the design and
operational aspects in detail.
