TELECOMMUNICATION

Manufactures EPABX and MAX systems based on C-Dot technology

It is necessary to run a number of internal cables between the following stages and frames:

Handset to exchange’s cable chamber Cable chamber to M.D.F. M.D.F. to L.D.F. L.D.F. to number block Number block to Exchange Equipment Between two exchanges Between two cities Between two countries

Manual &Automatic Telephony

Higher level of secrecy is maintained No possibility of the calls being missed or wrong

metering being done Running cost of the exchange is reduced

ELECTRONICEXCHANGES

Tone type: In this type of exchange sine wave is used. Their speed of dialling for a given number is more than that of pulse type.

Pulse type: In this type of exchange square wave is used due to which dialling speed is lesser.

ELECTRONICS EXCHANGE

M.D.F.

Place where both external and internal cables are terminated.

External individual cables carry conductors from subscribers

Internal cable conductors come from apparatus side Cross section between the two cables is done on the

M.D.F. through jumper wires M.D.F. carries all the protectors used in the exchange:

Fuses Heat Coils & Lightening Protectors.

Old MDFNew MDF

L.D.F.

These frames consists of a large number of verticals with horizontal cross arms fitted with tag blocks

The cable from M.D.F. is terminated on the multiple sides & from the exchange side cables run to the line cards

The two tag blocks are joined by jumper wires, so that any subscriber can be given connection to any uniselector on the line card

The subscriber’s uniselector are divided into different groups & these originate the same amount of traffic for smooth distribution.

TELEPHONE LINES

MAX Lines: MAX Ex. Lines are used for both internal (Intercom) and external communication links in BHEL.

EPABX Lines: also used for both internal and external communication links in BHEL. There are about 500 lines available in BHEL Haridwar

C Dot Lines: These are the direct telephone. The facility they provide is called DID. It has 24 lines.

CONNECTION TYPES

With wires i.e. Cables Underground cables Overhead cables

Wireless Microwave Links through Satellite

TYPES OF CABLES

In an exchange following types of cables are used:

Single Pair cable 2 Pairs cable 5 Pairs cable 10 Pairs cable 20 Pairs cable 50 Pairs cable 100 Pairs cable

COLOR CODINGTYPE COLOR OF WIRES

OPTICAL FIBER SYSTEM

Fiber optical transmission medium is fast emerging as a competitor to coaxial cables

Long distance data transmission in electrical cables suffers from ground loop problems. The basic material used in their construction is nonmetallic and electrically nonconductive.
