Line Equipment Remanufacturing. 

Selection 

The line gear equipment is received at the remanufacturing department where their lids are removed, inspected, and discarded if there is any damage caused by water, short circuiting, or physical imperfections. After being selected, all the needed accessories* are installed.
* Accessories: (Fuses, attenuators, equalizers, bodes, MDR, LDR, Jumpers, hybrids, filters, optical transmitter and receivers, etc……) .
Performance Tests 

After being selected and adding all its accessories, the line gear must then pass a few tests to ensure that the performance of the equipment complies with the manufacturer’s specifications, both in the forward and reverse signals.

Note: equalizers and attenuators used to test the equipment are at 0dB, in order to assess the performance of the equipment at its maximum gain.

Checking the level of voltage Teams Line

Line gear with internal power supplies included are tested in order to establish the voltage of the alternating and direct current (AC/DC); at the same time making sure they meet the requirements set forth by the manufacturer.

If the line gear does not have its own power supply, it is hooked up to an external power supply and its AC and DC are tested according to manufacturer specifications.

After satisfactorily passing these tests, the line gear is then tested with an audio and video program modulated to simulate its work in the field.

Customizing line gear

Following the tests, the line gear equipment proceeds to an area of personalization where they are prepared according to customer specifications.

Example: (attenuators, equalizers, jumpers, TDU, ADU, ACB Monitor, optical transmitters and receivers, etc. …) .

Housings are added, at the customer’s request, using the inserts required by the manufacturer.

Housing Remanufacturing

When our remanufacturing department receives housings, any missing pieces are added before the process begins.

Examples: Clamps, screws, bolts, etc…

The housing covers are closed, and all bolts are sealed to prevent the entry of water or any other solution.

After being sealed, the housings are placed in a cleaning and polishing machine, where they receive an intense cleaning treatment with chemicals and vibrations, which rub off the dirt and corrosion that they may have accumulated. At the same time, the machine polishes all the housings with the aid of small ceramic particles mixed with a special liquid solution giving the equipment a final touch.

The cleaning and polishing of the housings does not weaken its metal in any way thanks to the type of technology used. Instead, it gives the housing a shiny presentation and more protection to withstand storms and bad weather throughout the life of the equipment.

There are 0.05% of the housings that maintain some corrosion after the process of cleaning and polishing. These are returned to be cleaned with an Econo Finish Blast machine which removes the first layer of the surface of the equipment, resulting in the removal of any stubborn dirt or corrosion.

After the cleaning and polishing process, the housings are then rinsed and dried to remove any residues accumulated throughout the procedure.

In the final stage, the housings are open and verified to have no sign of water inside, ensuring that the sealing process is completely airtight.

Finally, the housings are ready to be ordered and are arranged in pallets where they can be shipped to the appropriate destinations.

Remanufacturing Power Supply Line

External line gear Power Supply Line without Stand By.

The External Power Supply is connected with an indicated voltage to verify the exit of AC voltage and the form that the wavelength displays, to make sure that they fulfill the specifications of the manufacturer.

External line gear Power Supply Line with Stand By.

Batteries are connected to the power supply (voltage varies based on model).

Next, the unit is connected to a specified voltage in order to measure the output voltage when connected and when there is an interruption in the power. This is done in order to introduce the change in wavelength and to ensure the output voltage is stable and can withstand an interruption in power (the output in the external power supply vary depending on the model).

The Finishing Touch

After all the tests are satisfactorily passed during the remanufacturing and repair phase, the equipment is given a warranty and security seal. These seals specify the order number, technician who inspected them, and date in which they were tested.

The power supply is connected to the corresponding amplifier where its AC/DC voltage is verified according to manufacturer specifications.

After passing the tests a security seal is applied.

Remanufacturing of the Power Supply Network

Power Supply without standby

The power supply is connected to an input of 110 Volts and the output AC voltage is verified according to manufacturer specifications.

After passing the tests a security seal is applied.

Power Supply with stand-by

The corresponding batteries are connected (the battery voltage varies with model).

Next, the power supply is connected to 110 Volts in order to measure its output voltage when it is connected and when there is an interruption in the 110 Volts of energy. The measure of the output voltage in both cases should be the same, since it should maintain a stable signal when the change is made and there is an interruption in the voltage. (the output on these power supplies vary depending on the model).

Finalizing

Having passed all the tests during the process of remanufacturing and/or repair, the equipment are sealed with a safety and security seal. These specify the order number and technician who supervised the process along with the date the equipment was tested.

The process of remanufacturing Cable Modems begins by checking their electrical circuits. At this stage the equipment is subjected to various tests where those with short circuit and other electrical faults are eliminated.

After their electrical performance is tested, the cable modems are scanned by a bar-code reader which records their serial number. The data is then introduced into a computer by order of make, model, serial number, date and time they were tested, and technician who supervised the process.

The Cable Modems are connected to the computer with a CMTS, enabling the registration of the Mac ID and the pairing with its serial number. This interconnection simulates the same atmosphere a real customer would, making it possible to verify its DOCSIS and the Upstream and Downstream capacity of each piece of equipment.

Once the verification of all their functions is finalized, the Cable Modems are cleaned and vacuum sealed. Their bar code is scanned one final time, this time in order to register the equipment as having passed all the tests, and then they are ready to be shipped.

The units are stored by groups in boxes, where they are numbered and ordered by pallets. Each pallet is marked according to the number of boxes it contains and the codes the cable modems contained in each box.

The Mac ID of each Cable Modem serves as a proof of guarantee. They are registered in our database as equipment that has passed all the tests, giving you the security and tranquility that only Neo Broadband can provide.

Our remanufacturing process for our converter boxes (Set Top Boxes) is considered one of the most modern, advanced, and accurate available on the market. We have top-of-the-line technology and a team of technicians with vast experience and preparation .

The process of remanufacturing converter boxes (Set Top Boxes) begins by checking their electrical circuits. At this stage the equipment is subjected to various tests where those with short circuit and other electrical faults are eliminated.

After their electrical performance is tested, the converter boxes (Set Top Boxes) are scanned by a bar-code reader and their serial number is introduced into different computers depending on the factory that made them. The computers verify, analyze, and register this number, where they are stored by make, model, order number, date and time they were tested, and technician who supervised the process.

The General Instrument (GI) converter boxes (Set-Top Box) are registered with an ACC computer. This allows access and connectivity to the programming that is sent from our headend, which enables us to test the performance of each converter box (Set Top Box) in a real environment setting, ensuring that the audio, video, encoding, channel package, and so on, are in perfect order.

The Scientific Atlanta (SA) converter boxes (Set-Top Box) are registered on a computer with System Manager that allows the downloading of the program and recognition of the set-top box security. This enables us to send the connection and programming via our headend, allowing us to test the function of the audio, video, encoding, channel package, and so on in a real environment setting.

After successfully passing these tests, we verify the performance of different types of Radio Frequency “RF”.

Once the verification of all their functions is finalized, the converter boxes (Set-Top boxes) are cleaned and vacuum packaged. Their bar code is scanned one final time, this time in order to register the equipment as having passed all the tests, and then they are ready to be shipped.

The units are stored by groups in boxes, where they are numbered and ordered by pallets. Each pallet is marked according to the number of boxes it contains and the codes the cable modems contained in each box.

The serial number of each converter boxes (Set-Top boxes) serves as a proof of guarantee. They are registered in our database as equipment that has passed all the tests, giving you the security and tranquility that only Neo Broadband can provide.

The boxes are connected to an electrical timer for 1 hour. This is done in order to verify that the electrical circuits of the boxes are in optimal condition.

Then with a bar-code reader, we introduce the serial number to the ACC or the System Manager in order to be checked and registered.

The boxes are checked to make sure they are in perfect condition (audio, video encoding, channel package, etc.).

Different types of RF (channels) are tested.

The boxes are cleaned, vacuum packaged, and a copy of the serial numbers is printed out for the client detailing the location of the units in each box.

* We test and reset (wipe out) every hard drive.

With the help of our headends for Motorola and Scientific Atlanta systems, a distribution network, and some specialized equipment, we simulate the real field experience starting from the input of the signal up until its output and final distribution. This gives us the opportunity to try out any headend equipment to the extent of its performance.

Modulators

The modulators are connected to the headend, where they transmit a radio signal often containing audio and video. This is so we can verify that it can tune in to the desired channel if it is an agile modulator, or if it is preset to a channel established by the manufacturer if it is a fixed modulator. At the end of the distribution, a decibel meter is used to determine how many decibels it is transmitting.

Encoders

The equipment is connected to the corresponding headend where an audio and video signal is sent in order to verify that it is encrypted properly according to the standards established by the manufacturer.

Combiners

In order to test the combiners we send different channel frequencies from the headend, where their performance is verified.

Data Comander/Data Pad Modulation

The Data Comander/Data Pad Modulation are connected to the header (GI) from where it sends an audio and video signal. In the same manner, the corresponding converter (Set-top Box) is connected depending on the frequency emitted by the Data Commander/Data Pad Modulation. These signals are used to view their performance, with the help of a Spectrum Analyzer which checks the gain and frequency.

Data Splitter

The header (GI) transmits different signals via the DPM to the data splitters. Their function is verified with different boxes according their corresponding frequencies.

Optical transmitters and receivers

We test the optical transmitters with a radio frequency signal that contains audio and video transmitted from the headend. The transmitters retransmit this signal and it is relayed to a node in an optic form. The node, in turn, transmits the signal to an optical receiver. The transmission and reception of the signal is measured and checked ensure that they meet the parameters specified by the manufacturer.

Monitoring

The performance of all equipment is monitored with the help of a TV and a converter box (if needed) connected to the grid of our headend in order to simulate the fate and performance in a real environment and ensuring that they are working as they should be.

Finalizing

After passing all tests in the remanufacturing and/or repair process, the equipment is stamped with a safety and security seal. These specify the order number and technician who supervised the process along with the date the equipment was tested.
