2.3.10 External Paging Encoder Port <br /> The External Paging Encoder Port feature allows an external tone paging encoder to be used with a <br /> dispatch console to provide tone paging services.Paging tones generated by the encoder are <br /> transmitted by the dispatch console on the selected conventional radio resource(s).If a user wants to <br /> send paging tones on an ASTRO®25 Conventional channel,an external paging encoder is required. <br /> This feature has an RJ45 connector with an analog 600 Ohm audio input to which the paging tones <br /> are applied.A Paging Push-to-Talk(PTT)input enables a dry contact closure to be applied that <br /> indicates when the dispatch console should transmit the tones on the radio channel(s). <br /> When the dispatch console sees the Paging PTT input go active,it transmits the audio appearing at <br /> the audio input on the selected conventional channel(s). If PL Stripping is enabled on a conventional <br /> channel,the PL is stripped when the paging tones are transmitted.No de-emphasis filtering is <br /> performed and no talk extend is provided with externally generated tones.Generally,the external <br /> paging encoder provides these functions. <br /> 2.3.11 Local Logging Recorder Port <br /> The Local Logging Recorder Port allows an external logging recorder to be connected to a dispatch <br /> console.The port provides an RJ45 connector with a 600 Ohm analog output.The audio that appears <br /> on this output is configured and is typically the audio that is transmitted and/or received at that <br /> dispatch console. <br /> The configuration of audio presented at this port is tied to the physical dispatch console,so that no <br /> matter what user is logged on the dispatch console,the same type of audio is logged.This <br /> configuration is done as part of configuring the dispatch console at the radio system's network <br /> manager.The local logging recorder port is configured to log any combination of the audio sources <br /> listed below: <br /> • Audio received from the currently selected radio resources.The level of this audio is not affected <br /> by either the individual volume setting of the radio resource or the master volume control on the <br /> speaker or headset jack. <br /> • Microphone audio being transmitted to the currently selected radio resources by the operator. <br /> • Microphone audio being transmitted to unselected radio resources by the operator. <br /> • Any tones generated by the dispatch console that appear in its speakers,such as trunking tones <br /> and emergency tones. <br /> • Tones generated by an external paging encoder. <br /> Long-term,console-specific audio recording is used to record a portion of the inbound and outbound <br /> audio present on a specific dispatch console.This recording is usually done by providing a logging <br /> port at the dispatch console and wiring that port to a track of an audio recording device.These <br /> recordings are typically archived for long-term storage and provide a historical record of the Radio <br /> Communications made at a given dispatch console. <br /> Orange County,North Carolina <br /> Use or disclosure of this proposal is subject MCC 7500 Console System <br /> to the restrictions on the cover page. <br /> 2-10 System Description Motorola Solutions Confidential Restricted <br />
