Trunked Simulcast System Overview Sample Clauses

Trunked Simulcast System Overview. Continuous Coverage‌ Simulcast provides continuous coverage over a large geographic area (wide area) using a single set of frequencies. In a simulcast system, all sites have the same set of frequencies. The same channel is the control channel at every transmit site. Overlap Zone‌ The challenge of a simulcast system is to provide high quality signaling to radios in the overlap zone. An overlap zone is the geographic region where two or more signals of comparable power are received by a single radio. To understand the overlap zone and its significance, an understanding of the concept of capture and non-capture zones is necessary. The simulcast coverage area contains two types of areas: those captured by a single site and those hearing two or more sites of approximately equal RF signal level.  Capture Zones – A radio (receiver) is captured by an RF signal when the mean signal level is higher than other RF signal sources by a margin strong enough to suppress the weaker signal’s modulation product so that data errors (missing data/voice frames) created by the mixing of the two signals do not disrupt the intended data stream from the mean signal.  Non-Capture Zones – In the "non-capture" or "overlap" zone, the mobile receiver accepts two or more signals. These signals mix randomly producing stronger or weaker signals. If one site’s received mean signal power level is within several decibels of other sites’ on-frequency modulated signals, audio intermodulation and distortion may occur. Audio distortion increases to a maximum when the received carrier signals are equal. In digital communications the distortion can cause data errors and result in distortion or missing voice (data) frames. Good communication in these areas is maintained by precision system synchronization and equalization. Control Point Basics‌ The Control Point is the central point for system control. The Control Point provides the necessary interfacing between two or more transmit sites and dispatcher locations. Timing references for outbound (transmit) data are generated here and sent to each transmit site and selection of the best quality inbound (receive) data from each site is managed by the Control Point equipment. Outbound (Transmitter) Signaling‌ Timing (or delay) for the outbound transmissions is adjusted by each transmit site to make the timing reference signals from the Control Point and transmit site match. Control of the exact time the common outbound signal is transmitted from each ...

  • Access Toll Connecting Trunk Group Architecture 9.2.1 If CSTC chooses to subtend a Verizon access Tandem, CSTC’s NPA/NXX must be assigned by CSTC to subtend the same Verizon access Tandem that a Verizon NPA/NXX serving the same Rate Center Area subtends as identified in the LERG. 9.2.2 CSTC shall establish Access Toll Connecting Trunks pursuant to applicable access Tariffs by which it will provide Switched Exchange Access Services to Interexchange Carriers to enable such Interexchange Carriers to originate and terminate traffic to and from CSTC’s Customers. 9.2.3 The Access Toll Connecting Trunks shall be two-way trunks. Such trunks shall connect the End Office CSTC utilizes to provide Telephone Exchange Service and Switched Exchange Access to its Customers in a given LATA to the access Tandem(s) Verizon utilizes to provide Exchange Access in such LATA. 9.2.4 Access Toll Connecting Trunks shall be used solely for the transmission and routing of Exchange Access to allow CSTC’s Customers to connect to or be connected to the interexchange trunks of any Interexchange Carrier which is connected to a Verizon access Tandem.

  • System Logging The system must maintain an automated audit trail which can 20 identify the user or system process which initiates a request for PHI COUNTY discloses to 21 CONTRACTOR or CONTRACTOR creates, receives, maintains, or transmits on behalf of COUNTY, 22 or which alters such PHI. The audit trail must be date and time stamped, must log both successful and 23 failed accesses, must be read only, and must be restricted to authorized users. If such PHI is stored in a 24 database, database logging functionality must be enabled. Audit trail data must be archived for at least 3 25 years after occurrence.

  • Network Interconnection Architecture Each Party will plan, design, construct and maintain the facilities within their respective systems as are necessary and proper for the provision of traffic covered by this Agreement. These facilities include but are not limited to, a sufficient number of trunks to the point of interconnection with the tandem company, and sufficient interoffice and interexchange facilities and trunks between its own central offices to adequately handle traffic between all central offices within the service areas at a P.01 grade of service or better. The provisioning and engineering of such services and facilities will comply with generally accepted industry methods and practices, and will observe the rules and regulations of the lawfully established tariffs applicable to the services provided.

  • One-Way Interconnection Trunks 2.3.1 Where the Parties use One-Way Interconnection Trunks for the delivery of traffic from Onvoy to Frontier, Onvoy, at Xxxxx’s own expense, shall: 2.3.1.1 provide its own facilities for delivery of the traffic to the technically feasible Point(s) of Interconnection on Frontier’s network in a LATA; and/or 2.3.1.2 obtain transport for delivery of the traffic to the technically feasible Point(s) of Interconnection on Frontier’s network in a LATA (a) from a third party, or, (b) if Frontier offers such transport pursuant to a Frontier access Tariff, from Frontier. 2.3.2 For each Tandem or End Office One-Way Interconnection Trunk group for delivery of traffic from Onvoy to Frontier with a utilization level of less than sixty percent (60%) for final trunk groups and eighty-five percent (85%) for high usage trunk groups, unless the Parties agree otherwise, Onvoy will promptly submit ASRs to disconnect a sufficient number of Interconnection Trunks to attain a utilization level of approximately sixty percent (60%) for all final trunk groups and eighty-five percent (85%) for all high usage trunk groups. In the event Onvoy fails to submit an ASR to disconnect One-Way Interconnection Trunks as required by this Section, Frontier may disconnect the excess Interconnection Trunks or bill (and Onvoy shall pay) for the excess Interconnection Trunks at the rates set forth in the Pricing Attachment. 2.3.3 Where the Parties use One-Way Interconnection Trunks for the delivery of traffic from Frontier to Onvoy, Frontier, at Frontier’s own expense, shall provide its own facilities for delivery of the traffic to the technically feasible Point(s) of Interconnection on Frontier’s network in a LATA.
