Call Recorder Manual ©-2001 Vidicode Datacommunicatie BV 7 1 Introduction The Call Recorder is an audio recorder with certain special features: • It has been specially designed to record telephone conversations • It has connections for a microphone, a telephone headset and a telephone line • It records digitally • It starts and stops recording automatically (or manually, if preferred) • It archives the recordings to facilitate searching • It highly compresses recordings, resulting in a large storage capacity • It can encrypt recordings using the optional Crypto Card for a high level of security • It can interface with computers and networks using the Ethernet interface and TCP/IP protocol with the built-in FTP server The Call Recorder can be configured to automatically record from any one of five possible signal sources • A telephone line that goes through the recorder • A telephone conversation conducted while the Call Recorder itself is in use as a telephone • A telephone line that is being monitored • The telephone handset • A microphone There are three different types of Call Recorder: • The Hard Disk Call Recorder, with an internal hard disk and a high capacity of 1950 or 3900 hours
Call Recorder Manual ©-2001 Vidicode Datacommunicatie BV 8 • The Flash Call Recorder, with enough memory to record the occasional conversation and a capacity of 3.5 or 7 hours • The LS120 Call Recorder, with exchangeable LS120 disks each having a capacity of about 32 hours. The Call Recorder can function as a recorder only, but also as a telephone or telephone answering machine, whichever you prefer. 1.1 Connecting to the Telephone Network to Record Calls There are four ways of connecting the Call Recorder to the telephone network: 1. As a stand-alone unit. The Call Recorder functions as a telephone which records the conversations conducted over it. 2. In series with a normal telephone. The Call Recorder automatically records the conversations on the normal telephone, but can itself still be used as a telephone at any time. A call on the normal phone can be monitored on the Call Recorder, both via the headset and the built-in loudspeaker. The recorder is activated by the line current as soon as the handset of the telephone is taken off the hook. 3. Via the handset connection of the telephone. The recorder is activitated when words are spoken into the handset and switches itself off when no sound has been detected for a certain period of time. 4. Parallel to a telephone line which is being monitored.W hen connected in this way, the line is not led through the recorder, so the recorder cannot monitor the hookswitch. In principle a telephone line could be tapped this way. It is used most often, however, to connect to a Call Recorder being used as a telephone

If there is no external contact the recorder is activated when people speak on the line, and de-activated when nothing has been said for some time. 1.2 Capacity of the Recorder The Call Recorder can be set to operate seven different audio compression techniques. The standard quality is meant for storage of telephone calls, and is comparable in quality to GSM; it is the one most often used by our customers. In those cases where the quality of the recordings is of special importance, it is possible to set a lower compression factor; the advantage is a significant gain in quality, the disadvantage a lower storage capacity. W hen only telephone conversations are being recorded, little is gained because the quality of the telephoneline itself is a limiting factor. High quality will make a difference, however, when one is recording a meeting, for instance. It is also possible to set a higher compression factor to raise the storage capacity. The highly compressed G.723 Low Rate still offers an acceptable recording quality though to most listeners it will be obvious that this is highly compressed audio. The various compression techniques are interchangeable. All you need to do is change the settings prior to recording. W hen the recordings are played, the recorder will recognize the compression method used. The table below gives an overview of the capacity of every model dependant on the compression method used.

The table above shows that there are three different types of Call Recorder: one with a hard disk, one with an internal flash memory and one with an exchangeable LS120 disk. Each type of recorder treats the medium it records from in a different way. The capacity of the storage medium has no consequences for the way a Call Recorder operates. A recorder with a hard disk of limited capacity operates in exactly the same way as one with a high capacity, for instance. 1.3.1 The Hard Disk Call Recorder A Call Recorder with a hard disk will automatically create space for new recordings by erasing the oldest ones when the disk is close to full capacity. This should be taken into account, and recordings that need to be kept longer should be archived. It should present no practical problems, because the capacity of this type of recorder is sufficient to store conversations of several years. The maximum number of recordings that can be stored in the recorder with a hard disk is 500,000 for all models, which means there are no practical restrictions. W hen after several years of use the hard disk is approaching its full capacity, the recorder will give a warning signal well in time for the user to check if there are any objections to the oldest recordings being overwritten. 1.3.2 The LS120 Call Recorder An LS120 Call Recorder not only has the capacity of the floppy disk at its disposal, but also an internal flash disk, which is equal to that of article no. 1280 (flash disk 16Mb). This implies that when the floppy disk is full, some four hours of recording time will be left, leaving ample time to place a new disk in the recorder.
