Radio over IP ROIP Gateway PTT board 

Overview:

Integrated Access Device Communications series is to develop products for specific applications, using the industry's popular chip technology to support E1, GSMWCDMA, PTT interfaces, FXO FXS, SIP, IMS interface, support for X86 industrial control panels, supports up to 4 ports E1T1, 96 ports GSMCDMA, 192 ports FXOFXS, 128 SIP trunks. Mainly used in IPCC, IP Dispatching, unify communications and some specific industries.

Host box description:

32 ports FXS Integrated gateway NC-MG320-X chassis contains two slots: one is for MCU card, aother is for various business cards.

NC-MG320-X uses advanced hardware and software technology and carrier-class design to ensure the high reliability of equipment. The system of NC-MG320-X uses the mature high-performance CPU and DSP; and uses embedded real-time operating system and efficient algorithm, so it has excellent properties. 

Introduction for each kind of board:

1. Power supply board:DC-48V or AC 110-240V;

2. MCU board: 1-4 E1 interface support for SS7PRIR2Q.SIGV5.2 signaling, 128 G.711 channels, 64 G.729, G.723, G.726 channel, 32 T.38 fax channels.

3. PTT interface board (Push to Talk, or RoIP):1-4 PTT interfaces, complete intercom voice signals into IP signals, access to the Professional Edition or Standard Edition RoIP groups to achieve the client and the host or the PSTN intercom communication.

4. GSMCDMAWCDMA interface board: 8 channels GSMCDMAWCDMA interface module supports voice and sms.

5. Analog User board: 16 ports FXOFXS module supports hot-plugged.

6. LAN switch board: as one LAN switch with 6 ports 10/100M.

7. Computer X86 Industrial Module:

·CPU: Intel Atom Dual Core N2600 1.66 GHz;
·1 x 2/4GB CF on PCIe
·1 x 32GB mSATA SSD on mSATA port 

·1 x 500GB SATA on SATA port (Notebook hard drive)
·2 x USB 2.0 ports on front panel

·2 x 10/100/1000 Ethernet ports on front panel
·1 x RS-232 Serial port (as Console) on front panel
·1 x Audio In port on front panel
·1 x Audio Out port on front panel
·1 x VGA port as pin-header on x86 board (VGA port can be used with a cable)
·1 x Additional USB 2.0 port on x86 board as pin-header
·1 x Additional RS-232 port on x86 board as pin-header
·1 x software programmable button on the front panel

8. MIPs board:

·Basic: 4-core, 1.2GHz, 1G or 2G memory, and eMMc 8GB;

·Additional function 1: 16 ports FE as LAN switch;

·Additional function 2: Ethernet Mirror;

Both X86 and MIPs boards are hardware, they are used for installing/loading customers’ own software.

9. E&M board:2 wire or 4 wire E&M; Support three standard types: I, II, V; Hot-plugged;

Each board supports 4 or 8 ports E&M; the physical specification of E&M port is RJ45.

Audio gain of each port can be adjusted independently by software.

   Carrier-class reliability

   ·With a new generation of processor, a separate high-end DSP processing chip and powerful hardware processing, ensure that the equipment at full load conditions remained stable and reliable;

   ·99.99% availability, support continuous long talk at least 48 hours;

   ·Support over-current protection function on POTS interfaces ;

   ·Support the protection of lightning, surges, power lines and other protective lap;

   ·Full compatible;

   ·Voice Activity Detection (VAD), to effectively save bandwidth resources;

   ·Comfort Noise Generation (CNG), to provide the same experience as PSTN in calls;
   ·Adaptive dynamic buffer technology, to meet the application under bad network;

   ·G.168 128ms echo cancellation technology. This indicator is far higher than the same kind of PBX, eliminating the echo interference caused by long distance call;

   ·DTMF detection / generation technology, to effectively support the business of the fax, callback, second dial.

   ·As a terminal, support the register trunk function to other GK(Gatekeeper) or SIP Server.

   ·As a gateway, support the control from superior GK or SIP Server to complete the trunking calls;

   ·Support any switch among E1, GSM, PTT, FXO, FXS, SIP, IMS;

   ·Support automatic routing function;

   ·Support high capacity of black and white lists;

   ·Simultaneously support the register of 4 SIP Server;
