Characters:
1. Lower cost
It can save 80% hardware cost of common computers, so the enterprise users can extend their computers easily.
2. No need maintenance
To maintain or update the host computers is enough. Easystation do not need hardware maintenance, timing updating the software of host computers is hardly.
3. Easy installation
The only thing needed is to install EasyStation services software on the host computer, then connect the host computer and Easystations by LAN, not need to install any softwares or other devices on EasyStation.
4. Small and exquisite, Low Power Consumption
It has smaller body, so you can get more working space. At the same time, it can save 60% electric energy or more.
5. Security
It has not any redundant devices connected, so can prevent data copying and virus.
5. Telnet access and control
By TCP/IP, EasyStation can access host computer, through internet, and host can browseor control workstation.

Neos3000a fixed cellular terminal serves as a gateway between a gsm network and your company private branch exchange (pbx). It connects to the analogue trunk of a pbx telephone system or a standard phone and routes your call through a sim card in the fct and out via the gsm network, converting the expensive pstn-to-gsm call into mobile-to-mobile call.

Product features:
1. Dramatic cost reduction
2. Signal strength indication
3. One voice channel pstn interface
4. Dual band gsm module (900/1800mhz)
5. Time controller: control outgoing time from 000~999 minutes
6. Counter unit: second, minute or call
7. Remote programming: setting via dtmf tones from the phone
8. Fake ring back tone: simulation of ring back tone
9. Lcr: least cost routing with automatic choice between gsm and pstn
10. Polarity reversal: recognition of call start / end
11. Built in caller id: calling party phone number display.
13. Mvpn: mobile vpns allow users to roam easily among various wired and wireless networks
14. Security lock-network / sim / pin lock, etc.
15. Fxs and fxo interfaces
