CX-OP1700

The operation station shall be designed for use within an IP audio communication system. Audio from and to the operation station shall be transmitted to and received by other devices via an IP network. The operation station shall allow full-duplex video conversations with other intercom stations in the network while providing echo cancellation and selectable intensity levels of noise cancellation. Conversations shall be able to be performed via a supplied handset, via connectors for a separately available headset or hands-free. For hands-free conversations, the operation station shall provide a separate loudspeaker and a microphone array. There shall be a setting to automatically reduce the volume of the conversation party that is currently quieter than the other one. A push-to-talk key shall enable the suppression of incoming audio.

For outgoing calls, it shall be possible to set a call time-out and the number of ringtone plays at the operation station. If the called station is busy, a busy tone shall be played back, and it shall switch to a call tone after the called station is available again. It shall be possible to make group calls which call multiple destinations at once until one destination accepts the call.

For incoming calls, it shall be possible to set a no response time-out, the response method (manual or automatic) and different forwarding destinations for automatic forwarding, time-based forwarding, forwarding in case the operation station is busy, no response forwarding, and forwarding in case the operation station has a malfunction. If multiple calls are incoming at the same time, it shall be possible to manually choose the call to be accepted.

For active conversations, it shall be possible to set a conversation time-out, to manually forward the other conversation party, and to manually put the other party into a queue.

The operation station shall provide the option to display the video feed of an ONVIF profile S-compliant IP camera during a conversation in addition to the video feed directly from the other conversation party. Additionally, the video feed of the operation stations own camera shall be able to be displayed. The display of the operation station shall provide options to switch between different setups of simultaneously displayed video feeds.

At least audio-only conversations with third-party SIP telephones shall be possible via a first-party server or a third-party SIP server.

It shall be possible for outgoing simplex transmissions to address at least 2999 destinations at once. Addressing third-party audio devices shall be possible at least via multicast audio using open protocols. Recordings of all transmitted audio and log files shall be storable on an external network drive.

The operation station shall allow the playback of chimes and pre-recorded audio files registered in the internal storage or stored in other devices in the network.

The operation station shall be able to activate an emergency mode for itself and other devices in the network. This mode shall deactivate low priority audio transmissions for those devices. The operation station shall be able to perform high priority emergency broadcasting and activate high priority pre-recorded audio files that can be transmitted despite an active emergency mode.

The operation station shall provide the possibility to manually record an audio file via an integrated microphone, pre-listen the recording through an integrated speaker, and play the file back at selectable destinations via the network. If all selected destinations are occupied by other transmissions, the playback shall be automatically delayed until the destinations are available again. Destinations addressed via multicast audio do not need to be considered regarding the delay.

Microphone and speaker volume adjustments and further software-controlled DSP settings shall be possible via setting software. The microphone shall provide at least a 2-band EQ filter, a compressor, automatic gain control, and automatic speech enhancement. The speaker shall provide at least a 7-band EQ filter.

A program timer shall allow the scheduled playback of audio files and change of volume and DSP settings. The program timer shall be adjustable via settings software, provide a calendar overview and allow separate settings for each day of the year.

The operation station shall be able to send a door open signal to an external door mechanism, receive a signal from the door mechanism, and display the current door state. It also shall be possible to send a door opening command to another station in the network.

System sounds for ringing, queue waiting, call transferring, pre-chime, post-chime, emergency pre-chime and emergency post-chime shall be separately customizable. It shall be possible to separately activate and deactivate system sounds for conversation start, conversation stop, and door unlocking.

The operation station shall be able to detect, display and forward at least the disconnection from the network, upload of a mismatching settings file, abnormal DC power supply, abnormal CPU temperature, unintended continuous holding down of a key, and hands-free microphone and speaker audio line malfunction. 

A touch screen LCD shall provide the possibility to start and stop audio transmissions, activate and deactivate control outputs, display device faults, change DSP settings, change timer patterns, display the time, and monitor the video feed of ONVIF profile S-compliant IP cameras. All mentioned LCD control options shall not be limited to control of the operation station itself but shall also include the control of other devices in the network. A manual device self-check shall be available.

The LCD shall provide a phone book with a capacity of at least 1000 call numbers of other stations in the network. It shall be possible to structure these numbers in at least 50 contact groups.

The LCD shall provide setting options, at least to set the brightness of the display, set the automatic display turn off time, and to turn the fault buzzer on and off.

The operation station shall provide at least two network ports for redundant network connections.

The operation station shall provide an angle-adjustable stand for desktop placement. Wall-mounting shall be possible via a separately available bracket.

The setting software shall be supplied with the product.
