9. 4. INDIAN RIVER COUNTY, FLORIDA MEMORANDUM TO: Jason E. Brown, County Administrator I THROUGH: Richard B. Szpyrka, P.E., Public Works Director FROM: Manny Cabo, Telecommunications Manager SUBJECT: AT&T ABN Long -Distance Calling Agreement - Extension DATE: May 16, 2018 BACKGROUND The AT&T ABN (AT&T Business Network) - long-distance calling agreement with Indian River County BOCC was approved, and executed by the County Administrator on June 30th, 2008. The original term of this IRC agreement with AT&T was 3 years from date of acceptance. The AT&T agreement expired on June 30th 2011. For reasons unknown to current IRC Telecommunications Manager and the Purchasing Manager (who now oversees the mailroom/switchboard, from whose account long distance costs are paid), the AT&T ABN long-distance agreement was never renewed. AT&T has been honoring the ABN agreement pricing structure, month to month, since expiration of the agreement. Recently, AT&T has been escalating efforts to convert all legacy AT&T Central Office equipment and services to new IP -based network Telecommunications systems. VoIP (Voice over IP) a network communications protocol, is one of the new Telecommunications services that are IP -network based. Recently AT&T has been increasing costs on long-distance calling services to everyone who does not have a currently active long-distance calling agreement. We have observed a 46% increase in long distance costs over the six-month average on the April invoices, and this extension will reduce our costs to the original contact agreement costs. AT&T refused the Telecommunications Manager's request to.refund that overage, due to the extensive duration the agreement has been lapsed. ANALYSIS AT&T legacy Voice Communications systems such as PRI (Primary Rate Interface), Centrex analog telephone lines, and 1 FB analog telephone services, are historically served out of AT&T Central Office locations, which are part of the legacy PSTN (Public Switched Telephone Network). AT&T is looking to retire all, or most of these old telecommunications services sites. The current projected date, which continues to be adjusted, based on information provided to County Telecommunications Department by AT&T, is sometime in 2020. The new IP -based network services will be served out of service resilient NOC (Network Operations Center) locations, from which AT ISP Internet services also originate. One of these new network Telecommunications services that will replace the old AT&T copper -based PRI services, that the County primary functions on for PBX telephone communications services is known as SIP Trunking (Session Initiated Protocol). County is currently in the process of converting our legacy PRI Telecommunications Trunks to the new SIP Trunking services.
