BS PD CEN/TS 17148:2018 provides a pro-forma template "Operational Support Agreement?(OSA) for guidance of?Public Authorities responsible for Emergency Services" (PARES) and Third Party Service Providers (TPSP) of third party assisted eCalls who are considering a formal agreement to accept eCall messages from a TPSP.While the decision as to whether or not to accept eCall from a particular TPSP, and the terms under which such calls are accepted from any particular TPSP remain firmly in the hands of the PARES and the jurisdiction under which it operates, it is considered to be advantageous to start such negotiations from a standard template. This document provides a pro-forma template which a PARES can require from any applicant TPSP, or an applicant TPSP can offer to any PARES that it approaches to request an agreement to accept their eCalls.Cross References:EN 16102:2011EN 16062:2015EN 16072:2015EN 16454:2015EN 15722:2015ETSI/TS 122 003All current amendments available at time of purchase are included with the purchase of this document.
