The Teleaction service provides the capabilities of a telecommunications network that sustains the exchange of low bit rate digital information. D
9、ata transmission shall be two-way simultaneous, two-way alternate or one-way dependent on the appli- cation requirement. The required directions of transmission are continuously available during the informa- tion transfer phase. A Teleaction service will normally interconnect a number of end users (
10、see 2.2.) to one or more receiving/ controlling centres (see 2.2.) such that messages from one end user will be conveyed to one or more receiving/controlling centres and/or messages received by a receiving/controlling centre will have come from a number of end users. The transmission of control/moni
11、toring messages in the reverse direction is also a requirement, Transmission delay shall conform to the delay categories of Table 1 (TISF 64) (under 3.2.l.h), as appropriate to the service application. 2.1.3. 2.1.4 r- o Edition of September 15, 1989,- CEPT T/SF*b4*E 89 W 2326414 0009532 O W 1 2.1.5.
