Poly 85Q60AA EHS module APP-51 for Savi & CS500 series content_copy

The Poly EHS module APP-51 is an adapter cable with integrated electronic hookswitch (EHS), specifically developed for connecting wired headsets from the Savi and CS500 series with Polycom IP phones. It enables electronic control of the handset hook, allowing incoming calls to be answered directly via the headset without requiring a mechanical handset lifter (e.g. HL10). The module is black and weighs 53 g.

Applications

The EHS module is used in professional environments where wired headsets need to be connected to IP phones. It is particularly suitable for call centers, office environments, and other workstations where fast and reliable call control via the headset is required. The connection is made via a modular interface on the IP phone, linking the headset base station to the telephone.

Functions and Features in Detail

The module integrates an electronic hookswitch that replaces the function of a mechanical handset lift. This enables electronic control of the connection between the headset and the phone. When an incoming call is received, the handset is automatically lifted" (i.e. the connection is established), and when the call ends, it is "placed down again. This allows for smooth and uninterrupted headset operation without requiring any physical movement on the phone.

Technology Explained Simply

The electronic hookswitch (EHS) replaces the mechanical handset lifter that would otherwise be required to control the phone via the headset. The module transmits control signals via the network cable (modular interface) between the IP phone and the headset base station. Control is achieved through electronic signals that simulate the states handset off-hook" and "handset on-hook. This allows the headset to directly handle calls without the user needing to move the handset on the phone.

Compatibility and Accessories

The module is designed for wired headsets from the Savi and CS500 series by Poly. It is used with Polycom IP phones that feature a modular interface. The connection is made via the module’s cable, which is attached to the headset base station and the IP phone. No additional accessories are required to use the function.

Installation and Mounting

Installation is performed by connecting the module cable to the headset base station and to the modular interface of the IP phone. The connection is simple and requires no additional settings on the phone or headset. Electronic control is automatically activated once the connection is established.

Operational Advantages

Electronic control of the handset hook improves office workflow efficiency. The user no longer needs to physically move the handset on the phone, which is particularly beneficial during frequent calls or when using headsets in call centers. The connection is reliable and reduces the number of required mechanical components, as the mechanical handset lifter (e.g. HL10) is no longer needed. The module is compact and lightweight, simplifying handling and installation.
