ISDN terminal having diagnostic function
First Claim
1. An ISDN terminal adapter having a diagnostic function, comprising:
- a terminal adapter section having a data rate converting function for communication with an office terminal of a distant station connected to an ISDN;
an S/T point interface section for converting an output signal from said terminal adapter section into protocol of said ISDN;
a D channel control section for receiving D channel information from the distant station through said S/T point interface section and extracting a sub-address from the D channel information;
a sub-address identifying section for determining whether the sub-address of the D channel information input from said D channel control section coincides with a predetermined code; and
a remote monitor section for setting a remote monitor state in response to a control signal generated in accordance with the determination result from said sub-address identifying section.

Abstract
An ISDN terminal adapter having a diagnostic function includes a terminal adapter section, an S/T pointer interface section, a D channel control section, a sub-address identifying section, and a remote monitor section. The terminal adapter section has a data rate converting function for communication with a terminal of a distant station connected to an ISDN. The S/T point interface section converts an output signal from the terminal adapter section into a protocol of the ISDN. The D channel control section receives D channel information from the distant station through the S/T point interface section and extracts a sub-address from the D channel information. The sub-address identifying section determines whether the sub-address of the D channel information input from the D channel control section coincides with a predetermined code. The remote monitor section sets a remote monitor state in response to a control signal generated in accordance with the determination result from the sub-address identifying section.
