Distributed Voice Logging based upon LAN / WAN
|
|
 |
|
Each 4
- channel Voice Logger module is equipped with network interface
Ethernet 10 / 100, which allows its connection in the network. Thus
any number of 4 - channel modules can work together in the network
making it possible search of voice records of all 4 - channel modules
in any single PC of the network. |

| SYSTEM FEATURES | |
| • Number of channels is
scalable up to 64. However, each module is of four channels. (Indicate
no. of channels required while ordering) • Modular construction • Easy installation and user-friendly software interfaces • Each Channel Bank is of four Channels • Compression Rate 64 KBPS to retain original voice. (Higher compression rates can be provided) • Separate indication for every channel recording in pogress • Can be interfaced with wireless, telephone lines. Thus various types of voice signal inputs can be fed to Voice Logger System simultaneously, allocating separate channel for each input • Records voice with date and time • Plays Voice by entering date and time • Plays any channel without interrupting recording of any other channel, including channel being played • Has Ethernet port to get connected in computer network • Play Control is by any computer in the network. • Record keeping can be done on CDs / Flash Memory • Computer programmable selection of VOX, Pseudo calls or off hook calls • GSM / CDMA Interface for recording (Fixed Cellular/CDMA Terminal to be provided by the buyer) • Recording remains uninterrupted even in case of defect in computer hardware and software (where recording is in flash memory / dedicated hard disk) • Play possible from every 4-channel module by using keyboard in stand-alone configuration only |
