The 8301 SIP Paging Adapter and Scheduler is designed to bridge a VoIP telephone system to a traditional analog amplifier / public address (PA) system. The endpoint is powered via PoE (IEEE 802.3af). Wall mount brackets are included for easy installation. The product is CSA/UL, FCC and CE certified.Seamless IP Interface to Analog PA SystemsAlgo 8301 (back view)The 8301 IP paging adapter emulates a page port, similar to what is found on a legacy PBX or key system. The adapter connects directly to a traditional analog amplifier, thereby offering a simple and easy interface to a VoIP phone system as a SIP extension and multicast endpoint.Wideband G.722 HD voice codec is supported in the 8301. Consequently, there is high intelligibility and clarity of audio from the paging adapter for IP paging of voice announcements and emergency notification. The isolated and balanced line output of the 8301 ensures there is no hum or noise.The line output of the 8301 IP paging adapter provides a dry audio output for any amplifier with input impedance between 600 Ohm and 10 kOhm, where the line output of the paging adapter can be defined to match the input specification of the amplifier. This means most amplifiers are supported by the 8301. Either XLR connector or terminal block is available from the 8301 for easy connection to an amplifier. A dry contact closure to activate the amplifier is also available, if required.Algo 8301 - IP Enabling Legacy Amplifier The 8301 can receive a SIP call and provide a line level output to a standard legacy amplifier. This accommodates voice paging, loud ringing and/or emergency alerting through the analog speakers connected to the amplifier. No ATA RequiredFor amplifiers connected to an FXS port or ATA through a 'telephone answering device', the 8301 IP paging adapter will replace the answering device and eliminate the need for an FXS port or analog terminal adapter (ATA). Note: The 8301 does not provide an FXS port.The 8301 paging adapter is only recommended to connect to a single amplifier. Where multiple amplifiers are used, one paging adapter is bridged to each amplifier. Multicast can be configured to stream audio to individual amplifiers or to any combination as required (e.g., all call page zone).An audio input on the 8301 IP paging adapter is isolated and balanced to prevent equipment ground loops where the adapter is used for auxiliary input or insertion between existing equipment. This allows IP based paging or emergency notification to take control of the amplifier as necessary.Legacy Zone ControllerWhere a legacy amplifier has a zone controller connected for page zones selected using DTMF key press from a telephone keypad, the 8301 can be configured to pass such tones through its audio output. Alternatively, the legacy zone controller can be replaced and the 8373 IP Zone Paging Adapter can be used to bridge the IP telephone system to the legacy amplifier.
