Overview + +The Digital Voice Modem (DVM) network stack is a sophisticated real-time communication system designed to transport digital voice protocols (DMR, P25, NXDN) and analog audio over IP networks.

The FNE master acts as the root of the tree, with additional FNE nodes forming branches. **Peers (dvmhost, dvmbridge, dvmpatch) are always leaf nodes** and cannot have children of their own. + +``` + ┌─────────────────────┐ + │ FNE Master (Root) │ + │ Primary FNE │ + └──────────┬──────────┘ + │ + ┌──────────────────────┼──────────────────────────────────┐ + │ │ │ + ┌───────▼────────┐ ┌──────▼──────────┐ ┌─────────▼─────────┐ + │ dvmhost #1 │ │ FNE Regional │ │ dvmbridge │ + │ (Leaf Peer) │ │ (Child FNE) │ │ (Leaf Peer) │ + └────────────────┘ └──────┬──────────┘ └───────────────────┘ + │ + ┌──────────┼──────────────────┐ + │ │ │ + ┌───────▼──────┐ │ ┌───────▼─────────┐ + │ dvmhost #2 │ │ │ FNE District │ + │ (Leaf Peer) │ │ │ (Child FNE) │ + └──────────────┘ │ └───────┬─────────┘ + │ │ + ┌───────▼──────┐ ┌───────▼─────────┐ + │ dvmpatch │ │ dvmhost #3 │ + │ (Leaf Peer) │ │ (Leaf Peer) │ + └──────────────┘ └─────────────────┘ + +Key Topology Rules: +┌─────────────────┐ +│ FNE │ ◄─── Can have child FNEs and/or leaf peers +└─────────────────┘ + +┌─────────────────┐ +│ dvmhost (Peer) │ ◄─── Always a leaf node, no children allowed +└─────────────────┘ + +┌─────────────────┐ +│ dvmbridge (Peer)│ ◄─── Always a leaf node, no children allowed +└─────────────────┘ + +┌─────────────────┐ +│ dvmpatch (Peer) │ ◄─── Always a leaf node, no children allowed +└─────────────────┘ + + +Alternative HA Configuration with Replica: + + ┌─────────────────────┐ ┌─────────────────────┐ + │ FNE Master (Root) │◄─────────►│ FNE Replica (HA) │ + │ Primary FNE │ Repl. │ Standby FNE │ + └──────────┬──────────┘ Sync └──────────┬──────────┘ + │ │ + ┌──────────┼──────────┬──────────┐ (Takes over on failure) + │ │ │ │ +┌───▼──────┐ ┌▼────────┐ ┌▼───────┐ ┌▼─────────┐ +│ dvmhost1 │ │dvmhost2 │ │Regional│ │dvmbridge │ +│ (Leaf) │ │ (Leaf) │ │ FNE │ │ (Leaf) │ +└──────────┘ └─────────┘ └┬───────┘ └──────────┘ + │ + ┌──────┴────────┐ + │ │ + ┌───▼──────┐ ┌────▼──────┐ + │ dvmhost3 │ │ dvmpatch │ + │ (Leaf) │ │ (Leaf) │ + └──────────┘ └───────────┘ +``` + +**Spanning Tree Features:** + +- **Loop Prevention**: Network tree structure prevents routing loops +- **Hierarchical FNE Structure**: Only FNE nodes can have children (other FNEs or peers) +- **Leaf-Only Peers**: dvmhost, dvmbridge, dvmpatch are always terminal leaf nodes +- **Multi-Level FNE Hierarchy**: FNE nodes can be nested multiple levels deep +- **Root Master**: Primary FNE master serves as spanning tree root +- **Branch Pruning**: Automatic detection and removal of redundant paths +- **Fast Reconvergence**: Quick recovery when topology changes occur +- **Mixed Children**: FNE nodes can have both child FNE nodes and leaf peers +- **Replication Sync**: Network tree topology synchronized across all FNE nodes +- **Peer Types**: + - **dvmhost**: Repeater/hotspot hosts (always leaf) + - **dvmbridge**: Network bridges connecting to other systems (always leaf) + - **dvmpatch**: Audio patch/gateway nodes (always leaf) +- **Configuration**: Enabled via `enableSpanningTree` option in FNE configuration + +--- + +## 2.

routing) +- **software**: Software version string (e.g., `DVMHOST_R04A00`) for compatibility checking + +**System Information Object (`info`):** +- **latitude/longitude**: Geographic coordinates in decimal degrees for mapping and adjacent site calculations +- **height**: Antenna height above ground level in meters (used for coverage calculations) +- **location**: Human-readable location

Overview + +The DVM (Digital Voice Modem) Host REST API provides a comprehensive interface for managing and controlling dvmhost instances. The dvmhost software interfaces directly with radio modems to provide DMR, P25, and NXDN digital voice repeater/hotspot functionality. The REST API allows remote configuration, mode control, protocol-specific operations, and real-time monitoring. + +### 1.1 Base Configuration + +**Default Ports:** +- HTTP: User-configurable (typically 9990) +- HTTPS: User-configurable (typically 9443) + +**Transport:** +- Protocol: HTTP/1.1 or HTTPS +- Content-Type: `application/json` +- Character Encoding: UTF-8 + +**SSL/TLS Support:** +- Optional HTTPS with certificate-based security +- Configurable via `keyFile` and `certFile` parameters +- Uses OpenSSL when `ENABLE_SSL` is defined + +### 1.2 API Architecture + +The REST API is built on: +- **Request Dispatcher:** Routes HTTP requests to appropriate handlers +- **HTTP/HTTPS Server:** Handles network connections +- **Authentication Layer:** Token-based authentication using SHA-256 +- **Protocol Handlers:** Interfaces with DMR, P25, and NXDN control classes +- **Lookup Tables:** Radio ID and Talkgroup Rules + +### 1.3 Use Cases + +- **Remote Mode Control:** Switch between DMR, P25, NXDN, or idle modes +- **Diagnostics:** Enable/disable debug logging for protocols +- **Trunking Operations:** Grant channels, permit talkgroups, manage affiliations +- **Radio Management:** Send radio checks, inhibits, pages, and other RID commands +- **Control Channel Management:** Enable/disable control channels and broadcast modes +- **System Monitoring:** Query status, voice channels, and affiliations + +--- + +## 2.
