J&R Technology presents the JR-TNS Series SIP Dispatching Server, a robust, scalable, and feature-rich communication platform designed to meet the demanding needs of mission-critical environments. Built on the universal Session Initiation Protocol (SIP, RFC3261), this system serves as the intelligent core for integrated voice, video, and data dispatch, enabling seamless command, control, and collaboration across a wide array of industries including public safety, corrections, transportation, energy, smart cities, and industrial complexes.
Core Architectural Advantages
The foundation of the JR-TNS system is its open standards-based architecture. By adhering strictly to the SIP protocol, it guarantees exceptional interoperability. The system seamlessly integrates with a vast ecosystem of third-party devices such as SIP phones, IP cameras (supporting Hikvision, Dahua, and others), network fire gateways, broadcast terminals, and SIP voice gateways. This openness allows for easy connection to existing IP communication infrastructures, protecting previous investments and simplifying system expansion. The platform supports mainstream audio codecs (G.711, G.729, G.723) and video codecs (H.263, H.264), ensuring high-quality media transmission across diverse networks.
Comprehensive Dispatching and Communication Suite
At its heart, the JR-TNS is a powerful dispatcher's console, unifying multiple communication streams into a single interface for unparalleled operational efficiency.
l Advanced Call Management: It supports a full suite of call functions including point-to-point dialing, hands-free operation, two-way intercom, group calling, multi-party conferences, forced call insertion/removal, call queuing, and silent monitoring.
l Intelligent Broadcast System: The system excels in audio dissemination with support for triggered, scheduled, instant, and shouting broadcasts. It features dynamic multicast technology with priority management, enabling efficient zone-based or facility-wide announcements, background music, and text-to-speech alerts in either multicast or unicast mode.
l Video Integration & Security Linkage: True situational awareness is achieved through integrated video functions. Operators can preview live feeds, switch video streams, and enjoy intercom-triggered video pop-ups (video linkage). The system is a cornerstone for security linkage, connecting alarms from fire, access control, or other sensors to automated responses like broadcast alerts, SMS notifications, or activating specific camera recordings.
l Geospatial Operational View: An integrated electronic map interface (supporting Baidu and Google Maps) provides visual management of assets. Operators can directly initiate intercom, broadcast, video, or alarm actions by interacting with layered map hotspots, dramatically improving response coordination.
Enterprise-Grade Management and Optional Billing Module
The platform offers granular administrative control through comprehensive modules for system, user, group, permission, and hotline management. A standout optional feature is the sophisticated Billing and Call Management System, specifically tailored for controlled environments like correctional facilities.
This module supports user authentication via 8-digit PINs or RF/IC Cards, tying usage to individual accounts. It provides complete financial lifecycle management: accepting payments from external parties (e.g., family), setting complex rate tables (per-minute/second, connection fees, minimum charges), defining free call allowances, and processing refunds. Robust reporting tools generate detailed Call Detail Records (CDR), summaries, and financial statements filtered by date, user, number, and other parameters. Extensive administrative permissions allow precise control over features like whitelist/blacklist management (with configurable recording and charging rules per entry), call flagging, and adding notes to call records.
Supervision, Monitoring, and Compliance
For environments requiring oversight, the JR-TNS delivers powerful monitoring capabilities. Supervisors can randomly monitor live calls via a round-robin mode or select specific calls for focused listening. During monitoring, they can flag calls, add notes, or terminate a live call with a recorded reason. The system ensures accountability and compliance by supporting full call recording (audio and optional video), with recordings easily accessible for playback directly from the call detail interface. A complete audit trail logs all administrative actions and financial transactions.
Technical Specifications and Scalability
The JR-TNS Series is available in four scalable models to match organizational size and call volume requirements:
JR-TNS-T60: Supports 60 registered terminals, 20 concurrent calls.
JR-TNS-T120: Supports 120 registered terminals, 50 concurrent calls.
JR-TNS-T240: Supports 240 registered terminals, 100 concurrent calls.
JR-TNS-T500: Supports 500 registered terminals, 200 concurrent calls.
All models share a common robust hardware profile: a compact 1U rackmount form factor (430 x 44.5 x 600 mm), low power consumption (≤35W), 500GB storage, gigabit network interface, and a wide operating temperature range (-10°C to +60°C). Each supports up to 8 concurrent recording channels and one console access point.
