RMS Glossary

Technical definitions for Teltonika RMS, eSIM, and related terms used across this site.

ACS (Auto Configuration Server)

A TR-069 protocol server used for mass management of CPE devices. Alternative to RMS for Teltonika device management at ISP scale.

Bootstrap SIM / Bootstrap profile

A minimal SIM profile pre-loaded on an eUICC that provides enough connectivity for a device to contact a management server and download its operational SIM profile. Enables zero-touch deployment.

eIM (eSIM IoT Manager)

The central management entity defined in SGP.32 for IoT eSIM. The eIM orchestrates SIM profile downloads, activations, and updates across a fleet of SGP.32-compliant devices. The natural integration point for IoT device management platforms like RMS.

eSIM / eUICC

Embedded SIM / Embedded Universal Integrated Circuit Card. A SIM chip soldered into a device (rather than removable) that can have its SIM profile changed remotely. See euicc.co.uk for the full technical reference.

Firmware

The operating software of a Teltonika device. Teltonika provides regular firmware updates (RutOS) that can be deployed remotely via RMS. Keeping firmware current is important for security patches and new feature availability.

LPA (Local Profile Assistant)

Software on an eSIM-capable device that manages communication between the eUICC and the SM-DP+ server for SIM profile downloads and management. Required for SGP.22. SGP.32 uses a lighter IoT LPA variant.

RMS (Remote Management System)

Teltonika’s cloud-based platform for remotely managing, monitoring, configuring, and troubleshooting Teltonika devices. Accessed at rms.teltonika-networks.com. Requires one credit per managed device.

RMS Agent

Firmware component built into Teltonika devices that maintains a persistent HTTPS connection to the RMS platform, enabling remote management without port forwarding or public IP addresses.

RMS Connect

RMS feature providing remote access to a device’s web UI and CLI via a browser-based proxy through the RMS tunnel. No port forwarding required.

RMS Credit

The licence unit required to connect one Teltonika device to the RMS platform. One credit per device. No expiry once activated. One free credit is included with every Teltonika device purchase.

RMS VPN

RMS feature that creates encrypted VPN tunnels between Teltonika devices and management hosts, using the RMS platform as the control plane. No dedicated VPN server required.

RutOS

The Linux-based operating system firmware developed by Teltonika Networks for RUT and RUTX series devices. Provides the web interface, CLI, and all router/gateway functionality including the RMS agent.

SGP.22

GSMA specification for consumer eSIM remote SIM provisioning. Defines SM-DP+, LPA, and the profile download workflow for consumer devices. Used in smartphones and some IoT devices. See also SGP.32 for the IoT-native alternative.

SGP.32

GSMA specification for IoT eSIM. Designed for constrained IoT devices with asynchronous operation and integration with IoT device management platforms via the eIM. The natural evolution for RMS-managed eSIM deployments. See sgp32.co.uk for full technical detail.

SM-DP+ (Subscription Manager Data Preparation Plus)

The operator-side server that prepares, encrypts, and delivers SIM profiles for download to eUICC devices. Central to both SGP.22 and SGP.32 eSIM architectures.

SNMP (Simple Network Management Protocol)

Industry-standard protocol for monitoring and managing network devices. Teltonika devices support SNMP for integration with third-party NMS platforms as an alternative or complement to RMS.

VoLTE (Voice over LTE)

The standard for delivering voice calls over 4G LTE networks using the IMS. Relevant to Teltonika TRB245 and similar voice-capable gateways used as PSTN replacements. See voltesim.co.uk for full VoLTE reference.

Zero-touch provisioning

A deployment model where devices configure themselves from factory-default state without manual intervention on site. Achieved with RMS via pre-provisioned credit assignment, configuration templates, and bootstrap SIM for eSIM-capable devices.
