Features
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
Industrial Applications
- Remote data monitoring & control (SCADA / telemetry)
- CCTV & security surveillance backhaul
- AMR automatic meter reading — water, gas, oil flow
- Power station & distribution network supervision
- POS terminals, ATM & vending machines
- Traffic signal & street lamp monitoring
- Fleet management & vehicle diagnostics
- Hydrologic / weather station data acquisition
- Telecom base-station equipment supervision
Always-Online Failover
Cellular, wired WAN and Wi-Fi client back each other up automatically. When one link drops, traffic switches in seconds — your SCADA polling never notices.
Serial DTU for Legacy Devices
Optional RS232/RS485 port bridges Modbus RTU meters and decades-old controllers onto IP networks. No forklift upgrade — the serial device just gains a 4G link.
Full VPN Suite On Board
IPsec, L2TP, PPTP and GRE tunnels terminate directly on the router. Site data reaches your platform encrypted, without extra security appliances.
Built for Outdoor Cabinets
Wide-temperature components, enhanced ventilation and a compact metal body fit cramped street cabinets and survive them. Rated for −35 °C cold starts to +75 °C summer heat.
Self-Healing Watchdog
A hardware watchdog plus multi-layer link detection restarts frozen links before anyone calls you. Unattended sites keep working for years, not weeks.
Fleet Management via NMS
Every H685T reports signal, traffic and status to E-Lins NMS cloud. Push configs and firmware to one unit or ten thousand — from a single dashboard.
