Page 3 EN 50136-2-3:1998 BSI 1998 1 Scope This standard specifies in addition to the requirements specified in EN 50136-2-1, the requirements for equipment used in digital communicat
24、or systems utilizing the public switched telephone network. The remote centre will normally be an alarm receiving centre but may be a satellite station with onward transmission using an alarm transmission system meeting the requirements of EN 50136-1-2. NOTEA satellite station is a normally unmanned
25、 connection point to which one or several alarm transceivers are connected for onward connection to an alarm receiving centre. 2 Object The object of this standard is to specify the performance characteristics of equipment used in digital communicator systems using the public switched telephone netw
26、ork to ensure their suitability for use with and compatibility with different applications. 3 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the
27、 publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies (includ
28、ing amendments). EN 50136-1-2, Alarm systems Alarm transmission systems and equipment Part 1-2: Requirements for systems using dedicated alarm paths. EN 50136-2-1, Alarm systems Alarm transmission systems and equipment Part 2-1: General requirements for alarm transmission equipment. ETS 300 001, Att
29、achments to the Public Switched Telephone Network (PSTN); General technical requirements for equipment connected to an analogue subscriber interface in the PSTN. 4 Alternative destinations Where the digital communicator includes a facility for dialling more than one alarm receiving centre dependent
30、on the message to be transmitted, the dialling sequence initiated by one event may be interrupted in order to allow the transmission of a higher priority event. 5 Equipment requirements Alarm transmission equipment within the scope of this standard shall comply with the requirements in EN 50136-2-1.
31、 In addition, the alarm system transceiver shall meet the following requirements. 5.1 Connection to first exchange of PSTN 5.1.1 From supervised premises Where the digital communicator is intended for use on a shared telephone line, the following requirements shall be met. a) If a telephone call is
32、in progress when a condition requiring transmission occurs, the call shall be terminated subject to PSTN requirements and the transmission procedure initiated. b) The digital communicator equipment shall not be damaged by connection to the same telephone line as equipment that meets ETS 300 001 requ
33、irements. 5.1.2 Monitoring A facility shall be provided for monitoring the integrity of the connection, e.g. by monitoring the voltage from the exchange, from the supervised premises to the first exchange of PSTN and providing this information to the associated alarm system. 5.2 Performance of power
34、 supply of the digital communicator No spurious transmissions shall occur as the result of failure or restoration of any power supply. 5.3 Operation The digital communicator shall be capable of the following sequence of operation, when connected to a telephone line, the purpose being that the digita
35、l communicator should send its message without unnecessary delay. NOTEWhere national or local requirements for equipment connected to national or private networks exist these should be met even when these requirements are contradictory to the requirements in 5.3. 5.3.1 Initiation of connection Follo
36、wing a change of the status of the interface to the alarm system the transceiver shall go off-hook within 4 seconds. After going off-hook, the transceiver shall wait until a signal has been detected indicating that the network is available and then begin the dialling process. The wait for the signal
37、 shall not exceed 7 seconds. An option may be provided to allow the delay for the signal to be set to an alternative, longer time limit for use in areas where it is known that the delay to the receipt of the signal normally exceeds 7 seconds. If the signal has not been detected within the time limit
38、 set, the transceiver shall go on-hook and start the sequence again. On the second and subsequent attempts to detect the signal the wait may exceed the initial time limit. 5.3.2 Establishment of connection The receiving centre transceiver shall detect the receipt of an incoming call and go off-hook
39、within 5 seconds of the commencement of ringing on its line. It shall begin transmission of a handshake signal within 2 seconds of going off-hook. Establishment of the connection to the correct party shall be detected by means of a handshake signal. If a connection is not successfully established wi
40、thin 40 s measured from the end of the dialling sequence, then the transceiver shall close down and repeat the procedure from the start.

41、s to connect A facility shall be provided to limit to 16 the total number of attempts made to connect to any one number. Where more than one number may be called then a facility shall be provided to limit the successive attempts to call one number before proceeding to the next number. Such attempts
42、may be limited by the requirements of the associated alarm system but shall not exceed 4. 5.3.4 Transmission of information After the handshake procedure has been completed the alarm system information shall be transmitted and correct reception of the information shall be confirmed by the transmissi
43、on of an acknowledge signal. Information concerning the event which initiated the digital communicator shall be transmitted although the event itself may have restored to normal. Information concerning other events which may have occurred during the dialling sequence may also be transmitted once the
44、 connection is established. The information message shall be repeated at least once if an acknowledge signal is not received within 5 seconds from the end of the message transmission. If an acknowledge signal is not received within 60 seconds measured from the start of transmission of the informatio
45、n message, the call shall be terminated and a new attempt made to establish a connection and transmit the information within the limitations specified in clause 5.3.1, 5.3.2 and 5.3.3. 5.3.5 Termination of call The digital communicator shall detect the receipt of the acknowledgement signal and, if i
46、t has no further information to transmit, shall either: a) close down and release the line during the remainder of the acknowledgement signal or within 2 seconds of the end of the acknowledgement signal; or b) switch to provide an audio channel between the supervised premises and the alarm receiving
47、 centre. In the latter case provision shall be made for the connection to be terminated by the alarm receiving centre operator. The receiving centre transceiver shall, if it is not required to switch to an audio channel, go on-hook within 5 seconds of the end of transmission of the acknowledgement s
48、ignal. It shall go on-hook, if the transmission is unsuccessful, within 15 seconds of the end of an incoming transmission or within 15 seconds from the time at which it detects the failure. A fault output shall be provided at the receiving centre transceiver interface to the annunciation equipment t
49、o indicate the unsuccessful activation. Following the termination of a call an attempt may be made to transmit the information message to a different alarm receiving centre or responsible person but further calls of the same message shall not be made to the original destination. 5.3.6 Failure to connect Information shall be provided by the supervised premises transceiver to the associated alarm system: a) if a fault is detected by the supervised premises transceive
