41、 protocol for point-to-point transmission of alarms and faults, as well as communications monitoring, between a Supervised Premises Transceiver and a Receiving Centre Transceiver using the Internet protocol (IP). The protocol is intended for use over any network that supports the transmission of IP

42、data. These include Ethernet, xDSL, GPRS, WiFi, UMTS and WIMAX. The system performance characteristics for alarm transmission are specified in EN 50136-1. The performance characteristics of the supervised premises equipment should comply with the requirements of its associated alarm system standard

43、and shall apply for transmission of all types of alarms including, but not limited to, fire, intrusion, access control and social alarms. Compliance with this Technical Specification is voluntary. 2 Normative references The following documents, in whole or in part, are normatively referenced in this
