How does a desktop broadcast intercom terminal complete calling and broadcasting through the touchscreen?
The operating logic of a desktop broadcast intercom terminal is to select the target first and then speak. This IP paging and intercom terminal puts the target-selection step on the 4-inch display screen with touch control, and all zone status and call information can be presented on the screen as a product showcase. The display screen has built-in numeric keys and function keys and supports touch-based calling and broadcasting; it supports calling a zone or multiple zones and can also broadcast to all zones, so on-duty personnel can complete addressing by tapping a zone with a finger. Zone paging means delivering the same voice to several broadcast zones in one operation; together with customizable one-touch call broadcasting on up to 10 keys, frequently used combinations such as a plant-wide announcement, a given station line or a given workshop are fixed to physical keys, so that a single key press sends the voice out in an emergency.
The device also retains the microphone broadcast calling path: it supports direct operation to call or intercom any terminal and supports broadcast calling through the microphone, with broadcast latency below 100 milliseconds. For dispatchers who prefer to press a key before speaking, the touch and microphone paths can coexist.
What protocols and private network platforms can the SIP broadcast intercom terminal connect to?
The core value of the SIP broadcast intercom terminal lies in replacing proprietary protocols with universal protocols. This terminal supports the SIP softswitch protocol, the MQTT Internet of Things (IoT) protocol and more, and can be registered directly with SIP-based softswitch platforms or with the dispatch systems of command and dispatch system manufacturers; it can also connect to Internet of Things (IoT) management platforms through MQTT, feeding call status and device online status into a unified backend. In a smart mining communication solution, the terminal can be networked together with intrinsically safe mining communication equipment, bringing underground and above-ground dispatch orders into the same converged communication network; in a government private network optical fiber communication solution, the terminal can complete access over the existing optical fiber backbone network without laying any dedicated line.
For system integrators, support for the SIP softswitch protocol, the MQTT IoT protocol and more means that no separate proprietary driver development is needed when interfacing with private network platforms - configuration follows the platform's existing SIP or MQTT access method. For end users, universal protocols mean the terminal can be brought into the same network for unified management together with existing SIP telephones, public address systems and dispatch consoles, instead of building another standalone system. The terminal also supports remote firmware upgrade through backend software, so later feature adjustments do not require visiting each site to plug in for an upgrade.
How do dual RJ45 connectors and PoE daisy-chain shared power supply save cabling?
This terminal has a built-in 1-channel network hardware audio decoding module and 2 network interfaces with RJ45 connectors at a 100 Mbps transmission rate, and supports power over Ethernet (PoE), daisy-chain connection and shared power supply - the dual RJ45 ports at 100 Mbps support PoE and daisy-chain shared power supply, saving cabling.
The practical significance of two network ports is twofold. First, cascading and redundancy: two RJ45 connectors allow a series connection of terminals in a daisy-chain manner, so that multiple terminals share the network and power supply of one link and the desktop needs only one access point. Second, combined power supply: with power over Ethernet (PoE), the terminal draws power and transmits data over the same network cable, so no additional power adapter or socket is needed on the desktop. In places with tight desktop space and limited sockets, such as substation control rooms, subway station duty rooms and plant dispatch rooms, every power cable saved is deployment cost.

Typical Application Scenarios
Energy and Electric Power: Dispatch Announcements for Substations and Power Plants
Dispatch announcements in substations and power plants require that an order arrive as soon as it is spoken. For substation dispatch announcements, is a 100 ms latency fast enough? The broadcast call latency of this IP access terminal is below 100 milliseconds - the interval from pressing the microphone to sound coming out of the remote terminal is under 100 milliseconds, meeting the real-time delivery of private network dispatch orders. The built-in 15 W full-range loudspeaker lets the duty operator monitor any terminal without wearing headphones. The terminal supports calling a zone or multiple zones, so one device can cover different areas such as the main control room, the switch room and the maintenance team; with its 1 on/off signal input and output, it can also be linked with on-site alarm signals.
Rail Transit: Train Dispatch Broadcasting for Subways and Railways
Broadcast points in subway stations and railway dispatching areas are scattered, making cabling and power supply costly. For broadcast in subway sections, can every possible cable and power feed be saved? This IP access terminal has 2 network interfaces with RJ45 connectors at a 100 Mbps transmission rate and supports power over Ethernet (PoE), daisy-chain connection and shared power supply; the station duty room can connect multiple terminals in a daisy-chain manner, occupying only one network access point, and the PoE power supply removes the desktop power adapter. The terminal supports touch-based calling and broadcasting, supports calling a zone or multiple zones, so platforms, station halls and entrances and exits can be paged individually by zone or broadcast to all zones, covering both routine announcements and emergency evacuation needs.
Industrial Manufacturing: Paging and Intercom in Plants and Chemical Industrial Parks
Paging and intercom points in plants and chemical industrial parks are numerous and maintenance windows are short. For plant paging and intercom, do remote upgrades still require on-site visits? This IP access terminal supports remote firmware upgrade of the terminal through backend software, so O&M personnel can issue an upgrade task from the backend to update the terminal firmware without visiting each workshop to plug in; it supports the SIP softswitch protocol, the MQTT IoT protocol and more, and can be brought into the plant's existing private network dispatching platform and Internet of Things (IoT) platform for unified management. The terminal supports customizable one-touch call broadcasting on up to 10 keys, fixing zone combinations such as process areas, tank farms and the gatehouse to shortcut keys, so that the duty operator can call with a single key press in an emergency.
Conclusion
In private network scenarios such as energy and electric power, rail transit and industrial manufacturing, whether dispatch orders can be delivered in real time directly determines the on-site response speed. The IP access terminal uses a 4-inch touchscreen to carry zone paging, guarantees real-time announcements with broadcast latency below 100 milliseconds, compresses cabling and power supply costs with dual RJ45 connectors and PoE daisy-chain shared power supply, and eliminates the external speaker with a built-in 15 W full-range loudspeaker: one desktop device completes the four services of paging, broadcasting, intercom and monitoring.
