Teltonika RUT956 4G LTE Industrial Cellular Router
The Teltonika RUT956 is an industrial 4G LTE cellular router designed for reliable connectivity, remote monitoring, industrial automation, IoT, transportation, energy, smart-city, and enterprise applications. It combines 4G LTE Cat 4, dual SIM, Wi-Fi, four Ethernet ports, RS232, RS485, GNSS, multiple I/O interfaces, USB, and advanced RutOS networking in a compact industrial enclosure.
Teltonika describes the RUT956 as an industrial cellular router that combines cellular, Wi-Fi, and wired connectivity with automatic WAN failover and GNSS capabilities. Its serial communication interfaces allow industrial and legacy equipment to be integrated into modern IP networks.
4G LTE Cat 4 Connectivity
The RUT956 supports 4G LTE Cat 4 with theoretical download speeds of up to 150 Mbps and upload speeds of up to 50 Mbps. It also supports 3G and 2G connectivity, subject to the exact hardware version, supported frequency bands, and mobile operator.
Cellular monitoring provides detailed information such as RSSI, SINR, RSRP, RSRQ, connected band, operator, IMSI, ICCID, cell information, and transmitted or received data. Band-lock functionality is available for supported configurations.
Dual SIM and Automatic Failover
The router features two Mini SIM slots and supports automatic SIM switching. Configurable switching conditions include weak signal, data limits, SMS limits, roaming, no network, network denial, data connection failure, and SIM idle protection.
This makes the RUT956 suitable for remote sites and industrial installations where connectivity redundancy is important. Two SIM cards can be used to provide an additional cellular backup path, depending on the operator and deployment requirements.
Four Ethernet Ports
The RUT956 provides four 10/100 Mbps RJ45 Ethernet ports. One port is configured as WAN and can also be configured as LAN, while three ports operate as LAN interfaces. The Ethernet interfaces support auto MDI/MDIX.
These ports can connect PLCs, industrial controllers, IP cameras, computers, switches, access points, monitoring systems, and other Ethernet-enabled equipment.
Wi-Fi Connectivity
The RUT956 supports IEEE 802.11b/g/n Wi-Fi and can operate in Access Point and Station modes. This allows the router to provide local wireless connectivity while using cellular or wired WAN connections for internet and remote network access.
The Wi-Fi subsystem can be used for local users, service personnel, mobile equipment, and suitable industrial devices that require wireless network access.
GNSS Positioning and Time Synchronization
A key feature of the RUT956 is its integrated GNSS capability. It supports GPS, GLONASS, BeiDou, Galileo, and QZSS, making the router suitable for location-aware applications and accurate time synchronization.
GNSS functionality can also be used with features such as NMEA forwarding, geofencing, and AVL-related applications, making it useful in transportation and fleet deployments.
RS232 and RS485 Serial Connectivity
The RUT956 includes both RS232 and RS485 serial interfaces. The RS232 interface uses a DB9 connector, while RS485 is available through a 6-pin industrial connector and supports both full-duplex and half-duplex operation.
Serial communication features include Serial-over-IP, Modbus gateway functionality, modem operation, console access, and NTRIP client functionality. This makes the RUT956 suitable for connecting legacy industrial equipment to IP-based networks.
Industrial I/O
The RUT956 provides multiple input and output options for industrial monitoring and automation. Depending on the hardware configuration, interfaces include digital inputs, an analog input, a relay output, digital open-collector outputs, and an additional digital input/output pair on the power connector.
Teltonika's I/O Juggler functionality can use defined I/O conditions to trigger events and actions, supporting applications such as equipment status monitoring, alarms, automation, and remote control.

WAN Failover and Network Backup
The RUT956 supports multiple WAN sources, including mobile, wired Ethernet, Wi-Fi WAN, and VRRP, which can be used in automatic failover scenarios. Load balancing is also supported for suitable network configurations.
This allows organizations to configure cellular connectivity as a primary internet connection or as a backup connection for wired networks.
Routing and Network Management
The RUT956 runs RutOS, Teltonika's OpenWrt-based Linux operating system. It provides routing, DHCP, firewall, VLAN, QoS/SQM, DDNS, load balancing, connection monitoring, traffic management, and other advanced network functions.
Management options include Web UI, CLI, SSH, SNMP, JSON-RPC, MQTT, Modbus, SMS, and Teltonika Remote Management System (RMS). This provides flexibility for both local administration and centralized remote management.
Modbus and Industrial IoT
The RUT956 is particularly suitable for industrial IoT because it supports several Modbus operating modes, including Modbus TCP client, TCP server, RTU master, RTU gateway, and Modbus over MQTT.
These capabilities allow serial industrial equipment and Modbus devices to exchange data over IP networks and cellular connections, making the router useful for remote monitoring, automation, telemetry, and machine-to-machine communication.
USB and MicroSD Expansion
The router includes a USB 2.0 Type-A host port for supported external devices such as storage, printers, USB-to-serial adapters, or additional peripherals. The internal MicroSD slot can provide storage expansion and supports applications such as Samba share and DLNA. Teltonika documents support for storage capacities up to 2 TB.
Security and VPN
RutOS provides firewall, NAT, VLAN, traffic-control, access-management, and VPN functionality for securing industrial and business networks. The platform supports multiple secure remote-access and site-to-site networking technologies, depending on firmware and configuration.
Security and management capabilities make the RUT956 suitable for installations where remote equipment must be accessed securely across cellular or wired WAN connections.
Remote Management and Cloud Connectivity
The RUT956 supports Teltonika RMS for remote device management. It also provides integrations with cloud and IoT platforms including Azure IoT Hub, Cumulocity, and ThingWorx.
These integrations can help organizations monitor deployed routers and connected equipment without requiring physical access to each remote location.
