61.8.4 Disconnect detection

Several telephone disconnect methods are used in different countries. It is vital to configure the correct method in order to use the device with the Telephone Interface. Please consult your telephone provider for the disconnect method. The Linksys SPA3102 supports the following methods:

•CPC, a brief removal of the tip-and-ring voltage;

•Polarity Reversal;

•Long silence;

•Disconnect tone recognition.

Most telephone providers in Europe do not use the line voltage or reversal methods. The SPA3102 must recognize the disconnect tone in this region. E.g. in The Netherlands, the disconnect tone consists of a 500ms 440Hz tone followed by 500ms of silence in a loop. The configuration syntax for this tone is: 440@-30,440@-30;2(.5/.5/1+2).

61.8.5 ISDN telephones

Digital ISDN telephones can also be used via a local PBX that provides an analog line to the voice gateway. In this case the local PBX must be configured to generate DTMF tones upon reception of the corresponding ISDN commands to indicated button presses. These DTMF tones are required to identify the user input on the telephone, such as call selection and zone selection, to the Linksys SPA3102 voice gateway.

Note

The Linksys SPA3102 treats the sequence **# as a special command to disconnect the PSTN line. So this sequence should not be entered by the user in the voice response flow (see

table 61.2). This could happen by mistake when numeric keys are missed while entering zone numbers because these are separated by a * and a # is entered to complete the zone entry.
