3、rnational Telecom- munication Union. The ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Conference (WTSC), which meets ev

4、ery four years, established the topics for study by the ITU-T Study Groups which, in their turn, produce Recommendations on these topics. Annex A to ITU-T Recommendations Q.601-Q.695 was revised by the ITU-T Study Group XI (1988-1993) and was approved by the WTSC (Helsinki, March 1-12, 1993). NOTES

5、1 As a consequence of a reform process within the International Telecommunication Union (ITU), the CCITT ceased to exist as of 28 February 1993. In its place, the ITU Telecommunication Standardization Sector (ITU-T) was created as of 1 March 1993. Similarly, in this reform process, the CCIR and the

6、IFRE3 have been replaced by the Radiocommunication Sector. In order not to delay publication of this Recommendation, no change has been made in the text to references containing the acronyms ?CCITT, CCIR or IFRB? or their associated entities such as Plenary Assembly, Secretariat, etc. Future edition

7、s of this Recommendation will contain the proper terminology related to the new IT structure. 2 telecommunication administration and a recognized operating agency.

A.l These are Forward Interworking Telephone Events sent from an incoming procedure

25、to an interworking procedure, or from an interworking procedure to an outgoing procedure. A.l.l FITE 1 means one of the digits 1-9, O, code 11, code 12 and code 15 (ST), when used as an address signal (i.e. not including their use for other information, e.g. language digits). Each FITE 1 represents

26、one digit only and that digits value is implicit in the signal. A.1.2 FITES 2, 3, 6, 7 and 8 are events representing country code indicators. These signals are not sent from the incoming procedure to the interworking procedure, since the country code indicator is a link dependent signal and is used

27、by the incoming procedure as part of the input information to the digit analysis. These FITEs are generated in the interworking procedure by the use of SPITE 22 (see Table A.3). A.1.3 FITES 4-8 are events representing echo-suppressor indicators. These signals are not sent from the incoming procedure

28、 to the interworking procedure, since the echo-suppressor indicator is a link dependent signal and is used by the incoming procedure as part of the input information to the digit analysis. These FITEs are generated in the interworking procedure by the use of SPITE 21 (see Table A.3). A.1.4 FITEs 9-

29、19 are events representing calling-purfy s category indicators and include telephone events derived from language digits, discriminating digits and calling-partys-category signals. Explanatory notes on the meanings and uses of FITEs (see Table A.l) 1 Explanatory notes to this table will be found in

These signals are not sent from the incoming procedure to the interworking procedure, but the nature-of-circuit

31、indicator is used by the incoming procedure as part of the input information to the digit analysis. These FITEs are generated in the interworking procedure by the use of SPITE 20 (see Table A.3). These signais are not completely link dependent, since if the nature-of-circuit indicator on the incomin

32、g circuit implies one satellite in the connection, the same signal (FITE 21) will be sent to the outgoing procedure. A.1.6 FITE 22 is an event representing the clear-forward signal and overrides all other procedures. It should therefore be shown as an input in all call states except idle, even thoug

33、h the waiting state might not appear to be capable of receiving FITE 22. A.1.7 FITE 23 is an event representing theforward-transfer signal and is assumed to be capable of reception after the state Address-complete when the register function is deactivated and the speech condition is set up. A.1.8 FI

34、TE 24 is an event representing the continuity signal in common channel signalling systems. When interworking from a channel associated signalling system to a common channel signalling system, FITE 24 must be generated by the interworking procedure. A.1.9 FITEs 25, 26, 27 are events which define the

35、continuity check requirements on outgoing circuits for common channel systems. A.l.10 FITE 30 is an event which defines the Services which have been requested and can be provided e.g., Speech, Closed User Group, Digital Connectivity, etc. A.l.ll FITE 3 1 is an event which defines the information to

36、be carried by the General Set-up Message (GSM). A.1.12 FITE A contains all the information elements which can be carried by the Initial Address Message (IAM) of Signalling System No. 7 ISUP.

This latter event is designated BITE 26, when signalling from the outgoing procedure to the interworking proced

45、ure. Since in most cases the forward signalling continues beyond the time that the address-complete is simulated, BITE 2 does not cause register deactivation in the incoming logic in the way that BITEs 3-7 do. The incoming procedure must wait for the subsequent reception of BITE 27 or BITE 28 (see A

46、.2.7 and A.2.8). A.2.2 to be deactivated. BITEs 3-7 are address-complete events which cause the speech condition to be set up and the register function , A.2.3 incoming procedure where the register function will be deactivated. They are separated according to the reasons of an unsuccessful call. BIT

47、Es 8-17, 19, 20 are call unsuccessful events which cause the return of a corresponding event to the A.2.4 BITEs 21-24 are answer events, differentiated where possible. A.2.5 BITE 25 is the event representing the clear-back signal. A.2.6 BITE 26 is an event signalling the simulation of address-comple

48、te condition by an outgoing signalling system which does not employ address-complete signals (e.g. No. 5 or Rl). If the incoming signalling system uses address- complete signals, BITE 26 is translated to BITE 2 in the interworking procedures, in other cases it is discarded. A.2.7 BITE 27 means that

49、an outgoing signalling system which does not employ address-complete signals has completed forward signalling (e.g. ST has been sent) and the speech condition should be set up. When used, it will follow after BITE 26. For incoming signalling systems employing address-complete signals, BITE 27 will always be expected after BITE 2. Therefore when both interworking systems employ address-complete signals, the interworking procedure must translate BITE 2 to BITE 2 + BITE 27. A.2.8 BITE 28 is used only from an interworking procedure to an incoming procedure in the case w
