Siemens QLCDM024DCBAN | Digital Line Circuit Module | 24 Digital Ports | HiPath 4000 / OpenScape 4000

Product Description:

The Siemens QLCDM024DCBAN (part number S30810-Q2111-X100) is an advanced Digital Line Circuit (DLC) module designed for seamless integration with the Siemens HiPath 4000 and OpenScape 4000 communication systems. This module offers 24 digital ports via the UP0/E 2-wire digital interface, serving as a critical interface between Siemens' digital telephones and the enterprise-level PABX system.

With its high-density design, the QLCDM024DCBAN provides a reliable solution for large-scale deployments, supporting both voice and data transmission over existing copper wiring, while delivering robust performance for modern enterprise telephony needs.

The "DC" designation in the model name refers to the Direct Current (DC) power management and enhanced signaling capabilities, making the module ideal for deployment in contemporary digital peripheral shelves.

Key Features and Functions:

1. UP0/E Digital Interface with Master-Slave Support:
   The QLCDM024DCBAN leverages the UP0/E digital protocol, which allows for Master-Slave configurations. This means that using a T-Adapter, two digital telephones can share a single port, optimizing wiring infrastructure and enabling more efficient use of existing resources.

2. Integrated Power Feed:
   The module provides DC power directly to connected digital phones. This feature powers internal processors, LCD displays, and attached peripherals like Key Modules (sidecars), ensuring phone operation even during power disruptions (as long as the PABX system is connected to a UPS).

3. Advanced Diagnostics & Monitoring:
   The QLCDM024DCBAN supports sophisticated self-test routines and diagnostic features. Key monitoring capabilities include:

• Line Interruptions: Detects wire breaks in the field.

• Short Circuits: Protects the system from electrical faults originating from the field.

• Terminal Recognition: Automatically identifies the type of Siemens handset connected (e.g., Optipoint 500 or OpenStage 40 T).

4. Hot-Swap Capability:
   The module is engineered for high availability. It can be hot-swapped into a live system without interrupting the telephony service. Once installed, the system’s central processor automatically detects the new hardware, downloads the required firmware, and restores the system to full functionality.

Installation & Connection Details:

• Mounting Location: The QLCDM024DCBAN module is designed to be installed in a Peripheral Shelf (LTS/LTU), such as the AP 3300 or AP 3700.

• Backplane Connectivity: The module connects to the backplane using a high-performance SIVAPAC connector, providing reliable communication between the system's control bus and the digital telephones.

• MDF Termination: The 24 ports are typically connected to a Main Distribution Frame (MDF) using high-density 25-pair cables (Champ or SIVAPAC to RJ21 cables).

• Handset Compatibility: Compatible with a variety of Siemens digital handsets, including the Optiset E, Optipoint 500/600, and OpenStage T (Digital) series.

Applications:

The Siemens QLCDM024DCBAN is ideal for enterprises that require high-density, reliable solutions for integrating digital telephones into their communications infrastructure. Typical applications include:

• Corporate Offices: Providing robust and scalable telephony solutions for large-scale deployments.

• Hospitality: Connecting numerous digital phones across hotel rooms and administrative areas.

• Healthcare Facilities: Supporting high-performance, easy-to-manage communication systems in large hospitals.

• Educational Institutions: Implementing a comprehensive, unified communication platform across campuses.

Frequently Asked Questions (FAQ):

Q: What is the function of the QLCDM024DCBAN module?
A: The QLCDM024DCBAN is a Digital Line Circuit (DLC) module that enables Siemens digital telephones (Optiset, Optipoint, OpenStage T) to interface with the HiPath 4000 or OpenScape 4000 communication systems. It provides 24 digital ports and supports high-speed voice and data transmission over existing twisted-pair wiring.

Q: Can the QLCDM024DCBAN module be installed without shutting down the system?
A: Yes, the QLCDM024DCBAN is designed for hot-swap functionality, meaning it can be installed into a live system without requiring downtime. The system will automatically detect and configure the module upon installation.

Q: How does the QLCDM024DCBAN module power connected telephones?
A: The module provides DC power directly to the connected phones over the same 2-wire digital line, ensuring that the phones remain functional even during power failures (as long as the central PABX system is supported by a UPS).
