DEFINITION The possibility for a customer to control certain supplementary services associated with an exchange termination other than the one from which the control commands are made. DESC
7、RIPTION This service allows a customer to activate, deactivate or interrogate register and erase supplementary services on his own line(s) by means of a control procedure sent remotely via the Public Switched Telephone Network. It may be possible to control, for example, the following supplementary
8、services by remote control: Call barring (both I/C and O/G single or multiline). Call diversion (immediate, on busy, or on no reply). Change to a remote call forwarding destination. Abbreviated dialling. General deactivation of Supplementary Services. General interrogation of Supplementary Services.
9、 Alarm Call. To protect lines from unauthorised changes a keyword must be used as part of the control procedure for remote control services. The keyword may be the same or different from the normal keyword, which may be needed to control supplementary services direct from the exchange termination be
10、ing controlled. The use of a keyword for remote control working negates the need for other keywords, i.e. only one keyword will be used for this service irrespective of what service is being controlled. It shall not be possible to control or interrogate a service, using remote control unless that se
11、rvice has been provided to the address being remotely controlled. A control or interrogation request made using the remote control service shall cause the same results as if requested direct from the controlled line. AU normal indications shall be provided to the remote customer. APPLICABILITY TO TE
12、LECOMMUNICATIONS SERVICES ISDN Telephony Note. Both ISDN and non-ISDN terminations shall be able to control both ISDN and non-ISDN lines. OPERATIONAL REQUIREMENTS Provision Provision of this facility may require an agreement between the Administration and the customer. The Administration shall be ab
13、le to make this service available on demand. Withdrawal Withdrawal of this facility will be at the customers request or for administrative reasons. Controlling customers requirements Registration It will be possible to register a change of keyword for use of remote control service direct from the li

Usage The subscriber will be able to use this service by means of a control procedure from any exchange termin
16、ation providing suitable signalling is available. The service shall be activated by a control procedure which includes a keyword. It shall not be possible to activate a service on a PSTN address unless that service has first been made available to that address by the Administration. As an option thi
17、s service may be deactivated when X attempts are unsuccessful due to the use of an incorrect password. X may be set to any value between 1 and 10. All confirmation messages relevant to individual services will be provided to the remote controlling customer using the same announcements that would be
18、received if changes had been made direct from the line being controlled. If activation of a service is rejected a reason for rejection should be given. Deactivation The controlling customer may, by use of a control procedure, deactivate this service. This may be done direct from his line or by use o
19、f the remote control service. Testing Where appropriate, it should be possible for a subscriber to ascertain that a service functions correctly, possibly by using it. In tessogation It should be possible by use of this service to remotely interrogate a termination to ascertain what services are oper
20、ative even if these services were not activated or registered remotely. It should be possible to individually interrogate numbers within a list but it is not necessary to request with one command that all registered numbers will be given. Should a customer request a service specific general interrog
21、ation for a service such as abbreviated dialling, selective diversion, selective barring or distinctive ringing then only the general interrogation announcement will be given followed by an additional announce- ment to advise the customer that it is not possible to list all numbers registered when i
22、nterrogating using Remote Control. Service Operation Requirements Exchange numbers with call barring, remote call forwarding or diversion facilities activated will be accessible for remote confrol service commands. Once a remote control command has been accepted the facilities provided by the contro
23、lled exchange termination shall be identical to the service as would have been provided by normal control procedures used from the line. A line being remotely controlled should be available for outgoing calls and changes made by this means shall not affect calls already set up or in the process of b
24、eing set up. If a line is being controlled from more than one source at a time and the service requests are incompatible then only the last request will be actioned. Changes made via remote control should have equal status as changes made direct from the line. Compatibility Requirements All Compatib
25、ility Requirements and limitations of the individual supplementary services shall apply. Remote control of supplementary service requests shall not be diverted or barred by any supplementary service activated on the home line. Remote control of terminations with Universal Access Number facilities ma
26、y not be allowed. Remote control attempts that fail due to busy shall not be able to activate completion of calls to busy subscriber service.

29、y accessed. These charges should include all relevant charges for access/change to the supplementary service being controlled and charges for use of remote control supplementary service.
