USP
Each specific implementation requires detailed technical and economical analysis. Parameters such as availability of commercial power, cost of energy, average temperature and seasonal variations, available space, vandalism sensitivity and many others.
We have identified four main objectives:
1. Make the installation fast and easy because there is no time to waste and “Time to Market” is essential.
2. Lower the cost of ownership. Having hundredths or thousands outside plants spread all over the country can raise the costs exponentially if care is not taken to MTBF, efficiency, easy repair and maintenance free. This includes also special handling of faulty TP.
3. Monitor the installation and provide extended reporting of operations. Continuity of service is essential since the Telco is bounded with a Service Level Agreement. Better to anticipate any problem and in case of disruption being able to troubleshoot quickly and accurately.
4. Keep the system very safe because reluctances from unions will jeopardize the deployment and no Telco can afford to make the headlines in the newspapers.
To achieve these goals following features have been implemented.
- RLP is fully protected against reverse polarity
- On the twisted pairs
- On the –48Vdc
- A toolbox is integrated to recognize, identify and test pairs to be connected according to the deployment scheme. Mistakes are rapidly detected, located and fixed. No extra accessory is required that would increase costs and puzzled the roll out logistic.
- Each twisted pair is monitored individually and full status is accessible.
- Power transmission is self-adaptive. RLP changes automatically operational parameters to get the utmost from the copper pairs whatever the gage and the distance are. No further adjustment is required in deployments where various distances and types of TP are simultaneously in service.
- “Hand-to-Hand” fault detection with current cut off as low as 20mA within 50msec.
Systems based on voltage regulation and limiters cannot do that at all. BPS is the only supplier offering this functionality with so low and fast values.
- “Hand-to-Feet” ground leakage is controlled to stay under 2mA. A value 15 times lowers than protection in service for bathrooms.
Such as they are both “Hand-to-Feet” and “Hand-to-Hand” features guarantee TOTALLY SAFE operation in full compliance with IEC 479 level Dc2.
Most of other systems proposed on the market are “likely” safe according to this standard. Translated in simple figures that means that 1 person among 700 might be injured when shocked.
Only BPS guarantees peaceful relationship with unions.
- RLP keeps safety performances:
- During Start up phase
- While one or several TP are defective whatever the problem could be
- During fault recovery sequence
- Ground leakage doesn’t interrupt power transmission. This defect is the most likely to happen because aging of insulators. It cannot be discriminated with Hand-to-Feet unsafe condition.
In order to maximise the “Availability” RLP controls the leakage and keeps going in supplying the load while satisfying the safety requirements in full compliance with applicable international standards.
Again BPS is the only supplier doing the things in that way.
- Start up sequence is performed in full SELV conditions (voltage less than 60V, current less than 5mA)
- RLP proposes the highest density of power in the remote cabinet considering true RFT-C systems offered on the market
- Remote converter offers the highest efficiency (close to 90%) on the market. A third less losses than competitors in the shelter where temperature control is crucial
- RLP is the only system working with natural cooling in the central office
- RLP is fully modular, hot swappable and expandable. Repair operation does not require any special skills neither specific tooling.
