Connect industrial equipment, local Ethernet devices, Wi-Fi clients, and two independent mobile-network paths through one managed gateway. The RUTM56 combines a 5G radio with LTE Category 19 fallback and a separate LTE Category 4 radio, allowing legacy and newer cellular services to operate in the same router. The RUTM56000000 configuration includes a Quectel EC200A-EU modem and a Quectel RG520N-EB modem for EMEA and APAC-oriented deployments. Five RJ45 Gigabit Ethernet ports provide wired connectivity for controllers, cameras, kiosks, payment equipment, and local networks. Dual physical SIM slots and eSIM support give administrators options for mobile service provisioning and path selection. Dual-band 2.4 GHz and 5 GHz Wi-Fi 5 supports local wireless access, while RutOS provides WAN, LAN, WLAN, and cellular interface management, IPv4/IPv6 services, DHCP, DNS, NAT, firewall policy, VLAN controls, static routing, diagnostics, configuration backup, and firmware management. Install the router where cellular resiliency and industrial I/O matter: the four-pin power connector accepts 9–50 VDC and includes one digital input and one digital output. LAN1 also accepts 9–50 VDC passive PoE input; it is not compatible with IEEE 802.3af, 802.3at, or 802.3bt power. HTTPS WebUI, SSH, SMS utilities with an active SIM, and Teltonika RMS support local and remote administration. Load balancing and failover allow the available WAN, cellular, and wireless interfaces to be configured for continuity requirements.
