The Beyertone music playback device, type 1700, is a professional device for playing MP3 music in telephone systems. It is used for continuous music playback in waiting areas or during calls, making the waiting time for callers more pleasant. The device is specifically designed for use in telecommunications systems and enables flexible, network-controlled configuration and music management.

Applications
This device is suitable for use in companies, practices, hotels, and other facilities requiring a telephone system with music-on-hold functionality. It integrates into existing telecommunications systems and supports a wide range of systems, including HiPath 4000, without requiring additional adapters. Music playback is provided via the telephone system, allowing callers to hear music during the waiting phase. The universal interface ensures compatible connection with various system manufacturers.

Functions and Equipment in Detail
The device features an integrated LAN interface, enabling configuration via a web browser. Settings can thus be adjusted over a local network or via the internet. Music files can be downloaded from a user-configurable URL via HTTP, enabling central music management. Automatic updates occur at a user-defined download interval, allowing music files to be regularly refreshed. The autostart and autoreplay function ensures playback resumes automatically after a power failure, without requiring manual intervention.

Technology Explained Simply
The integrated storage capacity of 10 hours allows sufficient music collection to be stored and played independently of an external source. Support for MP3 sampling rates up to 192 kBit/s ensures good audio quality, adequate for use in waiting areas. The galvanic isolation of the telecommunications interface protects the device and the connected telephone system from voltage spikes and enables safe, direct connection without additional adapters. The LAN interface allows remote configuration and monitoring over a network, simplifying maintenance and adjustment of music playback.

Compatibility and Accessories
The device is designed for direct connection to various telephone systems, particularly HiPath 4000 systems, without requiring additional adapters. The universal interface ensures broad compatibility with different telecommunications systems.

Mounting and Installation
Installation is performed via the integrated LAN interface and the telecommunications interface. Configuration is done through a web browser, requiring identification of the device's IP address within the network. Music files are downloaded via an HTTP URL, for which the corresponding URL must be configured in the device. Playback starts automatically once the device is powered on and resumes after a power failure.

Operational Advantages
Central music management via HTTP URLs enables flexible and centralized control of music playback. Automatic updates ensure music remains current without manual intervention. The autoreplay function guarantees continuous playback, even after a power failure. Galvanic isolation increases safety and prevents damage to the telephone system or the device itself. The integrated storage capacity of 10 hours is sufficient to store a sufficiently large music collection, playable independently of an external source.
