Product Content Description:

NSS Sentinel card seamlessly integrates with NSS Central Monitoring Station (CMS) software. Ideal for CMS, communities, Campuses, Industrial Complexes, Medical help, etc.
Sentinel card consists of a Radio/Telephone receiver/decoder, this card with NSS proprietary driver, it can work as a alarm receiver (Sentinel CMS) as well as a “smart” repeater station. (Sentinel SRS)
The Sentinel card seamlessly integrates and interfaces with NSS’s Server.
Three important parts of CMS: Sentinel card, CMS software, CMS servers.
NSS Sentinel card adopts DSP technology to apply multiple voice processing function. The hardware is composed of motherboard and module. Provide 8 channels and 16 channels motherboard, trunk, 2 channels voice, 4 channels voice modules, etc. It can apply different scale and function by different motherboard and module. Single chassis can support several NSS voice board collectively to apply trunk, play, record, FSK, and speech synthesis functions, etc.
1. Single board can provide maximum 8/16 channels telephone parallel processing ability. Provide different functions by different modules
2. Single chassis can plug 16 boards at the same time to provide 256 analog channels;
3. Every module can provide 2 channels (2 channels telephone), every channel can apply the functions according to module type as below:
A. Trunk channel: hook off, hook on, call in, call out, play and record, DTMF, analog trunk signal tone detect and polarity reverse tone detect;
B. Others: 2 channels voice module, 4 channels voice module, provide corresponding function, can refer to the instruction of ‘component’.
4. A number of NSS boards are internally connected by CT-BUS (H.100 cable) to build various-scale applications and establish communication between each board.
5. Call-in and call-out function: parallel and auto call in and call out function, detect the incoming call and analyze the call accurately;
6. CID: Support two CID modes: DTMF and FSK;
7. Digital playing and recording: support digital playing and recording functions with various formats;
8. DTMF sending and receiving: Accurate DTMF sending and receiving, adjustable sensitivity, can suit to different lines and terminals;
9. Provide standard FSK format data receiving and sending functions;
10. Provide Dialogic compatible voice format, and provide API programming interface which can be compatible with SR.1.1;
11. Board with JCT function can support CSP, fully support speech interruption and echo cancellation.
