Product Features
- Automatic Ringdown (ARD) Function
One-touch activation allows the master station to directly route calls to conference bridges or external alarm devices, eliminating the need for manual dialing.
- Plug-and-Play
The modular design enables quick deployment by simply inserting the module into a Tellabs 2-Wire ARD rack, reducing on-site commissioning time significantly.
- High Reliability
Built with industrial-grade components and compliant with the Telcordia GR-1089 reliability standard, it is ideal for long-term operation in carrier-grade networks.
- Multi-Terminal Compatibility
Works seamlessly with traditional analog phones, digital PBX systems, and modern VoIP gateways.
- External Alarm Interface
Integrated push ports support connections to community alerts, fire alarms, or other external warning devices, enabling emergency broadcast capabilities.
Structure and Components
- Front-End Terminal Block
Used for connecting 2-Wire lines (Tip/Ring) and 48 V DC power supply.
- Internal Logic Board
Implements ARD detection, signal shaping, and trigger control functions.
- External Alarm Driver Circuit
Provides programmable relay outputs for external alarm devices.
- Rack Mounting Brackets
Compliant with 19-inch standard racks, allowing installation in the same cabinet as other Tellabs modules.
Typical Application Scenarios
- Corporate or Government Internal Conference Systems
Enables rapid establishment of multi-party conference calls, suitable for command centers, emergency dispatch, and similar use cases.
- Public Safety and Emergency Broadcasting
Leverages the external alarm interface to automatically trigger community alerts and fire alarms.
- Telecom Carrier Local Loops
Delivers modern conference capabilities over legacy 2-Wire communication lines.
- High-Reliability Industries
Ideal for education, healthcare, finance, and other sectors with stringent requirements for reliable conference communications.
Installation and Maintenance Guidelines
- Rack Space Preparation
Ensure the cabinet has 1 U of available space and is equipped with 48 V DC power supply and grounding connections.
- Wiring Requirements
Use shielded twisted-pair cables or traditional 2-Wire telephone lines. Connect the Tip/Ring terminals to the master station’s ARD line respectively, with strict adherence to positive and negative power polarity.
- Configuration Steps
Enable the corresponding 9193 module in Tellabs management software (e.g., Tellabs Network Manager) and set alarm trigger thresholds if required.
- Functional Testing
After powering on, use a test phone to make an outgoing call and verify that the call is automatically routed to the conference bridge or triggers the external alarm.
- Regular Inspections
Check terminal tightness, line impedance, and power supply voltage every 6 months to prevent failures caused by corrosion or loose connections.
- Troubleshooting
- If no calls are made or alarms fail to trigger, first inspect power supply and line connections.
- If issues persist, use Tellabs diagnostic tools to read the module’s self-test logs and identify hardware or configuration problems.
