Questions & Answers

What is Recording System basic structure? How does it connect to the phone system?	Recording System is based on computer main unit with the addition of multi-line voice communication cards. The system can be easily expanded by adding more cards until the maximum capacity is reached, it can be more than one system interconnected by network (Cascaded System), and the system has its redundant that work as a secondary system to the base one. The system is usually connected in parallel to the station side of the phone system. Installation can be done with no interruption to the phone operation.
Will the system affect the voice level on the phone?	No. The system does not affect the voice level at all. People on the phone will not notice any difference whether the system is recording or not.
What is the capacity of the system hard disk? What if the capacity is not enough?	Standard equipment is a 160GB hard disk with two partitions. Partition C: (about 10 GB) is used to store the operating system and The Recording and Monitoring System software. Partition D: (the rest of the hard disk) is used to store voice records. If more hard disk space is needed, either a bigger hard disk can be used or two hard disks can be used serially for combined capacity.
How much voice data can be stored in a 1 GB disk space?	Voice data is always compressed and stored as voice record. 1 GB can store about 130 hours worth of voice records. About 2500 hours can be stored on a 20GB hard disk. When the hard disk is full, the old records will be replaced by new ones. If a system has 30 recording channels and each generates 4 hours voice records per day, it can retain voice records of the last 20 days on a 20 GB hard disk for instant access. Data backup is necessary when the hard disk can not retain voice records for the desired period. Backup media such as MO disk and DAT tape can be recorded over and over again.
How to distinguish between digital and analog telephones and how to connect them to the Recording System?	Digital telephones usually look more complicated and offer more functions than analog telephones. Business telephones are more likely to be digital, and household telephones are usually analog. Analog telephones can be easily connected to the system via parallel connection. Digital telephones can not be connected to the system directly. They must be connected either through a special D/A converter (significant cost increase), or by extracting the analog audio signal from the handset (more complicated wiring).
How is recording started and stopped?	Recording is started automatically by the detection of loop voltage or voice energy, and stopped automatically by the lack of loop voltage or voice energy. Loop voltage activation is usually used by analog telephones and voice energy activation is usually used by digital telephones and radio communication.
How many customers are currently using Recording   Systems?	Please refer to our Customer List. Our customers include companies in stock brokerage, transportation, telecommunication, broadcast and utilities. More than 200 systems have been sold worldwide, and more than 25,000 channels are in use.
What happens when the backup device is full?	The system speaker will play a warning message when the backup device is full, asking the system manager to replace the backup media. If the system is equipped with the optional alarm channel, the system will automatically call and inform the system manager about the situation.
What is the voice record format? Can voice records be played on other PCs?	Our voice record format is proprietary and not compatible with standard PC sound systems. However, voice records can be played and re-recorded to a regular cassette tape via the output jack on the system.
How to access and replay voice records over the LAN?	The optional Net play sound card can be purchased and installed into network terminals, allowing it to access voice records stored in Recording Systems on the same LAN. Both Windows XP and Windows server 2003 platforms are supported.
What if there is a power outage or the system is turned off by mistake?	We recommend that UPS (Uninterruptable Power Supply) be used to protect the system from power outages. The UPS should provide enough time to properly shut down the system until the power is restored. If the system has not been properly shut down when the power is lost, the “Rebuild.exe” program must be executed to rebuild index when the power is restored.
How reliable is the system?	Reliability has always been the most important design issue of Recording System. From CPU board, power supply to cooling fan, only high reliability, and industrial grade components are used to build the systems. Track record shows that Recording Systems are indeed very reliable in the field. The adoption of Windows XP and Windows Server 2003 as the operating system provides even further assurance of reliable system operation.
