Voice/Data Multiplexer (VMUX) Support
Repair and support for voice and data multiplexers, including the train control communication systems Indian Railways runs on.
Specialised VMUX cards, add/drop multiplexers and channel units - repaired at component level and tested against the traffic they will carry.
Specialised VMUX card repair
Voice cards, data cards, control and common cards diagnosed and repaired individually, then verified in a populated chassis rather than in isolation.
Add/drop multiplexer support
ADM equipment where a single failed tributary takes out a section. We repair the card and confirm the drop and insert paths behave under load.
Train control communication
Equipment carrying railway control traffic, where the reliability requirement is different in kind from ordinary office telephony and the testing has to reflect that.
Channel and interface units
E1, V.24, V.35 and analogue interface units returned to specification and checked against the equipment on the far end.
Rack-level fault tracing
When the failure moves as cards are swapped, the fault is in the backplane, the power or the timing. We trace it rather than replacing cards until it stops.
Spares assessment
An honest read on which of your held spares are actually serviceable, so your stores reflect reality before an outage tests it.

Something not covered? Ask us on the contact form — a person replies, usually the one who would run the work.
Do you work on railway signalling and control equipment?
Can you repair a card if we have no documentation?
Do you test cards in a live chassis?
PLCC Repair & Maintenance
Component-level repair of power line carrier equipment, down to the individual part rather than the whole card.

The power plant is what everything else in the rack depends on, and it is the part most often left until it fails.
