Advance Communication Trainers Lab Equipment Manufacturer, Supplier and Exporter in India

Four trainers are listed here: ACT-0001 EPABX, ACT-0002 Data Communication, ACT-0003 Telephone and ACT-0004 Antenna. One thing to know before enquiring: all four subjects also appear elsewhere on this site under different code series. An antenna trainer and an antenna trainer system are in the Communication and RF range, and an EPABX trainer and a telephone trainer are in the Vocational College range. Quote the code you want, ask which product is current, and ask the supplier to confirm you are not being quoted the same hardware twice under two codes.

What is in the range

ACT-0001, EPABX: analogue exchange or internet protocol system?

This is the first question, because installation work in the trade has moved largely to internet protocol telephony while most teaching exchanges are still analogue. Ask which you are being offered, then ask for:

• the number of extensions and the number and type of exchange lines, for example analogue trunk ports, digital lines or session initiation protocol accounts;
• how many handsets are supplied, since an exchange with one handset cannot demonstrate a call;
• the programming method and whether the programming guide is supplied, because an exchange that cannot be reconfigured by students teaches only wiring;
• which features the practicals cover, for instance transfer, hunt groups, restriction classes, direct inward access and call detail logging;
• whether faults can be inserted for fault-finding practicals, and whether there is a battery backup arrangement to demonstrate.

ACT-0003, telephone trainer: ask about the ringing supply

A telephone line is not a low-voltage circuit. The ringing supply on a subscriber line is an alternating voltage high enough to give an unpleasant shock, and it appears without warning when a call arrives. Ask the supplier what ringing voltage and cadence the trainer generates, whether the ringing generator is isolated, whether its test points are shrouded, and what the manual says about probing a line that may ring. Then brief students accordingly.

For the teaching content, ask which practicals are supported: tone generation and decoding, loop current and the hook switch, ringing detection, the speech circuit and sidetone, and the line interface. Ask whether both pulse and tone dialling can be demonstrated, whether the instrument can be opened and probed, and whether a line simulator is included so a call can be set up without a real exchange.

ACT-0002, data communication: hardware or software?

The name is plural and general, so establish what the item physically is before anything else: a hardware trainer, a pair of units with a link between them, or computer software. Then ask which of the following the practicals cover, because a data communication paper usually names most of them:

• Signalling standards and levels, for example the voltage levels and handshake lines of a point-to-point serial interface, and differential multi-drop signalling, with the ability to observe the levels on an oscilloscope.
• Framing, asynchronous against synchronous, start and stop bits, baud rate and the effect of mismatching it.
• Error detection, parity and cyclic redundancy checking, and ideally a way to inject an error and see it detected.
• Loopback and link testing, and whether bit error rate can be measured.
• Any network element, such as a local area network experiment, and whether that is this item or the separate trainer in the Communication and RF range.

Ask also what cables, connectors and level converters are supplied, and whether the trainer connects to a computer and if so with what software and licence.

ACT-0004, antenna trainer: plan the space and check the licence

An antenna measurement is not a bench experiment. Before ordering, settle:

• Space and reflections. Ask the recommended separation between transmitting and receiving antennas and give your room dimensions, because a pattern measured in a small room with hard reflecting surfaces will not resemble the textbook.
• Which antennas are supplied, typically a dipole, folded dipole, Yagi, loop and horn, and whether any are optional.
• How the pattern is taken. Ask whether rotation is motorised and whether the plot is produced automatically or read point by point, and if software is involved, on what platform and with what licence.
• Frequency and licensing. Ask the operating frequency and the radiated power, then confirm with your national spectrum authority that transmitting on it in a teaching laboratory needs no licence or that an exemption applies. This is the buyer's obligation.
• What else is needed to run the experiment, in particular a signal source, a detector or receiver and a standing wave ratio meter, which in the Communication and RF range are separate items.

What this range does not contain

If you are looking for the subjects usually meant by advanced communication, note what is absent here: satellite communication, cellular and mobile systems, optical transmission, microwave components and waveguide work, and software-defined radio. Optical transmission is on this site under Fiber Optics Communication Trainers, and microwave sources and standing wave measurement under Communication and RF Trainers, which also holds the digital modulation, coding and local area network trainers. Ask the supplier directly whether a mobile communication or satellite trainer can be supplied, since neither is listed.

Also worth confirming

The experiment manual with expected readings; the quantity per student group; which instruments each experiment assumes, since all four of these need at least an oscilloscope and the antenna work needs a source and detector; spares and consumables; the supply voltage, frequency and plug type for your country; and the warranty. Any performance figure quoted is confirmed in writing on the quotation; ask for its basis.

Request a quote

Send your practical list and ask for a quote stating, against each code, what is supplied with the trainer and which instruments it assumes. For example EPABX Trainer (ACT-0001), one set, with the extension and line count, the number of handsets and the programming guide confirmed in writing. Contact Ray Export for prices, manuals and lead times.

Frequently asked questions

Is the EPABX trainer an analogue exchange or an IP system?

The listing does not say, and it is the first question to ask, because installation work in the trade has moved largely to internet protocol telephony while most teaching exchanges are still analogue. Then ask for the number of extensions and the number and type of exchange lines, how many handsets are supplied (an exchange with one handset cannot demonstrate a call), the programming method and whether the programming guide is supplied, and which features the practicals cover, such as transfer, hunt groups, restriction classes, direct inward access and call detail logging. Ask too whether faults can be inserted.

Is the telephone trainer safe for students to probe?

Only with the right precautions. A telephone line is not a low-voltage circuit: the ringing supply is an alternating voltage high enough to give an unpleasant shock, and it appears without warning when a call arrives. Ask what ringing voltage and cadence ACT-0003 generates, whether the ringing generator is isolated, whether its test points are shrouded, and what the manual says about probing a line that may ring, then brief students accordingly. For teaching content, ask whether pulse and tone dialling can both be shown and whether a line simulator is included.

What does the data communication trainer actually include?

ACT-0002's name is plural and general, so first establish whether it is a hardware trainer, a pair of units with a link between them, or computer software. Then ask which practicals it covers: serial signalling levels and handshake lines, observable on an oscilloscope; asynchronous and synchronous framing, start and stop bits, and baud rate mismatch; parity and cyclic redundancy checking, ideally with error injection; and loopback, link testing and bit error rate. Ask what cables, connectors and level converters are supplied, and what software and licence any computer connection needs.

What do I need to plan before ordering the antenna trainer?

Space, licensing and the other instruments. Ask the recommended separation between transmitting and receiving antennas and give your room dimensions, because a pattern measured in a small room with hard reflecting surfaces will not resemble the textbook. Ask which antennas are supplied and which are optional, whether rotation is motorised and whether the plot is automatic or read point by point. Ask the operating frequency and radiated power, and confirm with your national spectrum authority that no licence is needed or an exemption applies; that is the buyer's obligation.

Does this range include satellite, mobile or optical communication trainers?

No. Satellite communication, cellular and mobile systems, optical transmission, microwave components and waveguide work, and software-defined radio are all absent from this listing. Optical transmission is on this site under Fiber Optics Communication Trainers, and microwave sources and standing wave measurement are under Communication and RF Trainers, which also holds the digital modulation, coding and local area network trainers. If you need a mobile communication or satellite trainer, ask the supplier directly whether one can be supplied, since neither is listed.

What else do these trainers need to run the practicals?

All four need at least an oscilloscope, and the antenna work also needs a signal source, a detector or receiver and a standing wave ratio meter, which in the Communication and RF range are separate items. Ask for the experiment manual with expected readings, the quantity per student group, spares and consumables, the supply voltage, frequency and plug type for your country, and the warranty. When you send your practical list, ask for a quotation that states, against each code, what is supplied with the trainer and which instruments it assumes.

Key takeaways

• EPABX: analogue or IP first: then the extensions, lines, handsets and whether students can reprogram it.
• Treat the telephone line as hazardous: ask the ringing voltage, isolation and test-point shrouding, and brief students.
• Find out what ACT-0002 physically is: hardware, a linked pair of units or software, before comparing practicals.
• Antenna work needs room and clearance: give your room dimensions, and check frequency and licensing with your spectrum authority.
• Budget for the instruments: all four need at least an oscilloscope, and the antenna trainer needs a source, detector and SWR meter.
• Check for duplicates: all four subjects also appear under other code series, so confirm which product is current.
