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 or 802.11b/g/n in H700 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 H720 router has both xDSL 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

The product supports TDD-LTE Band 38 (2600 MHz), Band 39 (1900 MHz), Band 40 (2300 MHz) and Band 41 (2500/2600 MHz), with fallback to TD-SCDMA (2010-2025 / 1880-1920 MHz) and EDGE/GPRS/GSM quad-band (850/900/1800/1900 MHz). Other TDD-LTE band combinations are available on request - see the datasheet for the full band list.
Yes - the product is carrier-unlocked and accepts any standard SIM/UIM card. APN is auto-detected for most carriers. Before ordering, confirm your carrier operates TDD-LTE Bands 38/39/40/41; for FDD-LTE regions (most of Europe / the Americas), choose the H820 series instead.
Yes. With the RS232 or RS485 option, the router works as a serial-to-cellular DTU gateway, transparently tunneling Modbus RTU traffic from meters, PLCs and RTUs to your SCADA center over TCP/UDP. Configuration takes minutes in the Web UI.
Insert an activated SIM, connect power (5-40 V DC - 12 V / 24 V cabinet and vehicle supplies work directly), attach the antenna, and the router registers on the network within about a minute. Default Web UI is at 192.168.8.1; APN, failover and VPN are configured in a guided flow. Most sites go from unboxing to online in under 10 minutes.
Yes - the compact metal enclosure is designed for street cabinets, pole boxes and control panels, with a -35 °C to +75 °C wide-temperature design and enhanced ventilation. Wall-mount and DIN-rail kits are available as accessories; the Hardware Installation Guide covers grounding and wiring.
Yes. The product supports three-way failover between 4G/3G/2G cellular, wired WAN (xDSL via RJ45) and Wi-Fi client mode. You can choose cellular-preferred or WAN-preferred backup strategies, and a built-in watchdog automatically restarts the link if the connection drops - an always-online design.
Yes - a full VPN suite: PPTP, L2TP, IPsec and GRE, with IPsec PKI digital certificates and extended authentication for compatibility with third-party VPN concentrators. IP/MAC filtering and an SPI firewall protect against DoS attacks.
All E-Lins routers integrate with the E-Lins NMS cloud network management system - remote monitoring, bulk configuration, firmware upgrades and alerts. SNMP (MIB-II + private MIB), Telnet, SSH2, Web UI and SMS status control are also built in. Learn about NMS →
Yes - firmware updates run over the Web UI, via the Configuration Tool over LAN, or in bulk through E-Lins NMS for entire fleets. Dual-image fallback means a failed update never bricks a remote unit; the step-by-step procedure is documented on the Wiki.
Every product carries a 5-year limited hardware warranty, a 30-day return policy on standard units, and lifetime firmware updates. Extended warranty and advance-replacement SLAs are available for volume and OEM projects.
Yes. E-Lins has provided OEM/ODM services since 1999: custom firmware, branding, enclosure and feature options (RS232/RS485, GPS, SMS/voice control, RIP/OSPF/BGP, PoE). Evaluation customization starts from a single unit; production branding typically starts at 50 units.
Standard models have no MOQ — order one sample to validate your application. Standard lead time is 2-4 weeks depending on options and quantity; volume pricing starts at 10 units, OEM pricing at 50+. Request a quote and receive a formal offer within 4 business hours.
