The Exchange Complexity
A typical Indian Telecom Exchange has the following plant entities:

1. MDF
2. Vertical
3. Cables
4. Cabinet/Pillars
5. DP

A simple network may probably not require any computerization effort. But the actual ground reality is very dynamic and is always changing. Fault repairs; new connections; subsequent increase in plant items - the network that was so simple now appears complex and interwoven.

Records are being maintained manually as well as digitally. But there is no integration of most of the data so that a meaningful analysis can be done. More often than not data is not readily available. It is spread out here and there. And it is mobile too - its always there in the small diary that the linesman personally carries.

The network complexities together with non-availability of data does make life miserable for managers and engineers of our telephone exchanges.

TeleLogic - Logical Solutions for Complex Networks
TeleLogic is basically designed to plug in complexities associated with a typical Indian Telephone Exchange.

The concept of connectivity is fundamental to TeleLogic. And herein lies the core strength of the system. The inherent connectivity logic makes possible network tracing and identification of plant items that are linked together.

Functionality

	Creation and editing of exchanges; vertical; cables; cabinet; pillars; distribution pillars; junctions; manholes and like with user friendly data input screen and checks and validations.
	Facility to terminate a cable at ET or DT of a connected entity. The termination box also displays faulty/damaged/spare pairs or the terminals of the entity. Pair in and pair out is also reflected instantly.
	Facility to trace a pair or a group of pairs based on either qualitative or quantitative criteria's. You can trace a faulty pair or a set of pair or a specified set of pair or by typing in a telephone number.
	Interactive trace lets you trace one junction at a time and allows to make changes to the network simultaneously. It makes the task of reaching an unknown entity easier by logically tracing the network.
	In-built and on-line ripple affect. Changes in the network are immediately reflected throughout the network.
	The system facilitates printing of standard reports that you always require.

The Data Availability Aspect:
Generally the following data-set is required:

1. Map of the exchange
2. Location of plant items of the exchange
3. Jumpering, termination and subscriber data

One of the most frequently asked question is - Where is the data? Needless to say, the data has to be keyed in. It is seen that data is always available in an exchange till the primary level, in some form or the other. Like a schematic diagram of the network could be a good starting point. Other network details can be integrated later. The subscriber database in many exchanges carries a lot of details providing information on jumpering and termination also.

Street level maps of many Indian cities are now available.

Newer techniques like physical trace of a pair from the MDF to the DP are now being implemented in many exchanges round the country.

Data can be generated. And TeleLogic provides you a tool to build this network of tomorrow.
