Brief

The E-Lins industrial routers have been specially designed to be installed in extreme environmental conditions such as exterior racks, urban elements (street lights, information screens, bus stops, etc.), industrial warehouses, production lines, vehicles, exterior telesurveillance systems, etc.

Highly resistant elements have been used to design and manufacture these industrial routers, both electrically as well as mechanically and resistance to extreme temperatures has been priorized by using low consumption components and increasing ventilation.

E-Lins has developed an industrial wireless router H750, which also supports ADSL. This industrial 2G/3G/4G router possesses specific characteristics which has enabled it to comply with the demanding requirements impossed by the utilities market (suppliers of Electricity, Gas, Finance, etc.), hence making it compliant with most industrial router scenarios.

What This Product Does

Get and share the freedom of 2G/3G/4G! The H750 2G/3G/4G Wireless N Router allows users to share mobile 2G/3G/4G broadband connection with machines nearly anywherein 2G/3G/4G coverage. Insert a SIM/UIM card (some networks flash the SIM/UIM card into the router), with simple configuration, a cellular broadband connection is created, and Wi-Fi hotspot is instantly established.

2G/3G/4G Wireless Sharing H750 series router features blazing high speed, allowing users to share a 2G/3G/4G mobile broadband with different devices via wired or wireless connection.

Tests in the Field-High Compatibility

Compatibility is the most important aspect to consider when you're selecting a 2G/3G/4G router. To ensure the best compatibility, E-Lins has made certain that our 3G/4G Routers are compatible with the ISPs in the regions in which they are sold. We have teams around the globe continually testing our Routers with the networks and carriers to ensure that end users can feel confident that their routers will operate flawlessly where they live and work. 3G/4G and Wired WAN Connection Redundancy (Backup Strategy)

The H750 Router stands out with its 2G/3G/ 4G and WAN connection back-up, which keeps users online when one connection fails. E-Lins' 2G/3G/4G Router provides users with both 2G/3G/4G Preferred and Wired WAN Preferred back-up modes, while other brands provide one or the other. This brings users a high degree of flexibility when users are setting up the networks with considering connection costs and length of downtime.

Wireless N Speed & Range

Complying with the IEEE 802.11n standard, H750 Router can establish a WiFi wireless network with transmission speeds of up to 300Mbps, while mitigating data loss over long distances and through obstacles in a small area locally. Above all, users can easily pick up their wireless network's signal at longer distances from the router, where with legacy 11g products they would have to be much closer.

Highlights

Details

Advanced WWAN technology for the utmost reliability - Embedded WWAN interface, fully integrated into the router engine. All the E-Lins intelligent network features are available through the WWAN interface. - Built-in module modem, with two SIM card tray, insert SIM card to work directly, no need dongles. - Detailed WWAN diagnostics for SLA audition and accounting. Information such as serving and neighbour cell received signal power, the operating frequency band, the WWAN technology used and the instant bitrate is available both in the router CLI and in its cellular interface MIB, so it can be retrieved by the SNMP management station at any time. Furthermore, a history report of the received signal power evolution in the past hour is also available. - AT command Line interface for low-level RF module management (sim-lock, WWAN carrier customization, etc).

Ready for WAN Ethernet services The full VLAN support, the state of the art in routing and bridging features, QoS and VRF-Lite addresses this router for Metro-Ethernet services. Furthermore, the Standard and Private Ethernet MIB support in these routers allows for SNMP remote management.

100% Wireless solution(version with WLAN WiFi Feature) An embedded WLAN Access Point (802.11b/g/n in H750 router) with dual external WiFi antennas (default is one WiFi antenna, option is two) can be equipped inside the router, providing cellular connectivity to local WiFi equipment. Support for IEEE 802.11 security guarantees communication privacy and confidentiality in the Wireless LAN segment.

ADSL/WWAN integrated and compact solution The E-Lins H750 router has both ADSL and WWAN interfaces in addition to a 2 port switch and the possibility of WLAN in a compact and competitive device thus meeting all branch offices’ communication needs.

Serial port for PoS/transaction services or to provide a WAN access through a point-to-point line (Version with serial port feature) - Compatible with any company point-to-point line terminal, asynchronous serial (RS.232, raw ASCIL, RS-485), synchronous serial (X.25, SDLC) or even Ethernet (SNA). - Compatible with point-to-point WAN services up to 2Mbps (Frame Relay, HDLC, X.25). - Efficient migration to IP in costs for payment applications over point-to-point lines. - The router converts serial transactions to IP (XoT, DLSw, transparent transport). This means that the point-to-point PoSs currently in the company can be used.

Best in class performance in mobile VPNs - Crypto-processor incorporated for “wire-speed” data encryption in VPN scenarios. - Fully parameterized IPSec Client/Server. Advanced IPSec features such as PKI encryption (Digital Certificates), extended authentication, and Reverse-Route Injection guarantee compatibility with third party VPN solutions. - PPTP/L2TP/IPSec/GRE Tunnels. - IP filtering, MAC filtering and SPI firewall protect the router against DoS attacks.

Carrier-class management - Powerful CLI, adapted for a professional router management. - Human readable configuration files. - Syslog client allows for the report of any event detected by the E-Lins Event Logging System. - SNMP agent with MIB2 and Private MIB support. E-Lins routers can be easily integrated into the Centralized Management System. - Remote router management through the E-Lins Router Management System. - Remote Web
