Telemonitoring system for telephone lines

0001The present invention deals with a system of remote monitoring of telephone lines which gives a solution to the need of monitor, in real time or recorded telephone lines dedicated to surveys, telesales or telemarketing, Assisted advertising, services to clients or similar applications. The following will discuss more generically to "steps taken across the line phone "or just" steps "for such of the type of tasks described above where the system proves as applicable the invention.

0002Conventionally, a series of operators / trainers support the above type of tasks using the lines telephone, or when they receive communications or when make them. From the information obtained, we arrive at conclusions give shape, in each case, the report resulting from the study.

0003The system according to the invention offers the possibility, in the tasks of the above mentioned type, listen to conversations at a time when they are realized, remotely through the telephone line:    It is characterized in that it consists of:<sl><li>a) a hub bringing together phone lines all approaches and lines dedicated to one line or more dedicated to remote monitoring;</li><li>b) a logic board, microprocessor-based connected to a personal computer via a modem;</li><li>c) an electronic equipment based on a microcontroller with a telephone and audio interface and a frame human voice messages recorded in EPROM; </li><li>d) means to control / regulate both time Monitoring of each incoming call that the general operation of system.</li></sl>

0004The system board can operate independently or in slave mode.

0005Electronic equipment is mounted in a box metal which contains internally a single electronic card with all system components and submit to externally both a basic network connection and fuse as the / base (s) connection for telephone lines and indicators of state line active, monitored by the central unit or in conjunction with the test line.

0006For legal reasons outside the scope of the invention:<ul><li>The lines are always to monitor lines Proprietary.</li><li>Calls are emitted from the monitored lines.</li><li>Monitoring is carried out on the part of the plant telephone belonging to the company offering the service.</li></ul>

0007The system according to the invention, is completely transparent to the monitored lines, it does not alter the impedance and the bond audio is done unidirectionally through a filter impedance high.

0008The monitoring lines allow only listening, they never allow to modulate the tested line.

0009The system has the ability to pick the line monitoring when he calls and disconnect by time or end a call.

0010It scans each line subjected to monitoring and detects if it is operational or not at all times.

0011The communication being established, it samples the line corresponding in turn or randomly, if this line it hangs to the next, in turn, or to another randomly.

0012The communication time can be determined from system, disconnection occurring after that time has elapsed determined, at least to maintain indefinitely thank you of the incoming call to consultation.

0013To better understand the object of the present invention, it represents in terms preferential practical embodiment, subject to accessory changes that do not turn away in the foundation.

0014Figure 1 shows the block diagram of the system of remote monitoring of telephone lines according to the invention, with its components base and the interconnection between them.

0017Will be found described hereinafter an embodiment practical, non-limiting of the present invention.

0018The system of the invention solves the need to monitor live telephone lines dedicated to approaches type that described above.

0019To address this need the invention three solutions are envisaged:

- LOGIC SYSTEM

0020Consisting of an electronic equipment which supports the following functions:<ul><li>Picks up incoming line consultation (LE).</li><li>Ensures monitoring of lines (LM) investigation.</li><li>Cut the communication time (adjustable by example, between 15 and 150 seconds).</li><li>Each call shows the following line.</li></ul>

0021Increments cyclically.<ul><li>input lines (LE)</li><li>Lines subject to monitoring: (LM)</li></ul>

- INTELLIGENT SYSTEM

0022Electronic Equipment based on a 8031 ​​controller family, telephone interface and audio human voice message store recorded in EPROM.

0023The equipment performs the following functions:<ul><li>He picks up the incoming line consultation (LE).</li><li>It reproduces lines messages menu operational.</li><li>It allows to select the line (LM) to be submitted to monitoring using the dial pad.</li><li>Recording consultations carried out with reference day and time.</li></ul>

0024unlimited time monitoring.

0025Cutting communication when the terminal by train call hangs up.<ul><li>input lines (LE): a</li><li>Lines subject to monitoring (LM): up to 16.</li><li>Control by DTMF tones.</li></ul>

- SYSTEM BASED ON PERSONAL COMPUTER

0026Equipment configured from a PC structure, board modem, voice carrier and specific application for managing incoming calls, which supports the following services:<ul><li>Picks up incoming line consultation (LE).</li><li>Monitore and selects lines (LM) investigation, the via the telephone dial.</li><li>Saves file with lines and date / time of consultations carried out.</li><li>input lines (LE): a</li><li>Lines subject to monitoring (LM): up to 256</li><li>customizable outgoing messages from PC.</li><li>Monitoring time: Up Hang-up line.</li></ul>

- GENERAL CONFIGURATION

0027Electronic equipment mounted in housing Metal (C) 430 x 85 x 260 for 19 "rack.

0028Internally, it contains a single electronic card 120 x 240 mm, with all the system components.

0029Externally, it has, in its rear part, a network connection base (9) - Power source - and fuse holders (10) .On the front it has two rows of connection bases for ten telephone lines (3), (4), and another more, identified as "test" (5) (6). There on each connection base two led displays (1), (2), a on the other, the bottom green lights when the line is active, the top one red, to indicate when this line is monitored by the central unit, or that the connection is established with the test line (5), (6).

0030The led displays on the test line (5), (6) indicate: green every call tone of the test line, the red when the connection happened.

0031The control unit (7), situated near this line, for example regulate time monitoring for each incoming call.

0032At the right end is the main switch (8), which is actuated by a key.

- OPERATION

0033The equipment being connected to the grid (9) and the switch (8) being actuated, the upper LEDs (1) (red) light sequentially simultaneously probed what each line (LM) connected to the system.

0034When there is a call on the test line (LE), this call is detected and there is the effect of dropping the line, at the same time that is established the association with the signal present on the monitored line which will be the first to introduce a carrier signal (active). When calling Next, the monitored line (LM) will be presenting the next activity, the Previous switching to a lower priority. All lines (LM) having activity in the face of continuous test calls (LE) are all that way monitored sequentially.

0035If during a test call, once established link with a line, the latter being monitored if this line ceases to have Activity monitoring to the next line.

0036If there is a test call, and if there is activity on no line, it occurs the establishment of a sequential link with each line, until one of them this activity, to stop there.

0037Once the connection between the test line (LE) and one of the lines subject to monitoring (LM) an adjustable timer from the command of the front portion (7) turns on. Time is being elapsed, the call "hangs" and so ends the monitoring cycle.

0038If one wishes to continue the monitoring, it will be necessary to recall.

- MONITORING

0039The test line (LE), at rest, is connected directly a call detection circuit (DT), high impedance, so that if the equipment is not electrically powered (9), nothing happens, and the call is given as unanswered.

0040In working conditions, the test call (LE) active connecting this line to the output of an amplifier (AF) by means of a in isolation transformer.

0041The amplifier (AF) determines the signal for optimal listening conditions.

0042The binding occurs in only one direction. In this way, test call (LE) does not disturb the existing connection on the line monitée (LM). In other words, the test line (LE) can simply listen, but not speak.
