Use of reply functions
The intelligent reply functions are easy-to-use, always operational test functions for the following purposes:
- Verification for the initial operation of connections by the customer
- Functional testing of connections by the customer
- Verification for the initial operation of end devices
- Functional testing of end devices and software installations for IP communication
- Setting and parametrising of end devices and applications
- Functional testing of additional services
All calls to the answering functions and call-backs are logged by the system and centrally stored.
Use of the reply functions
The reply functions were designed to ensure that their use requires little prior knowledge. The functions can be used by experts or directly by end users, e.g. to perform initial functional tests or to complete the initial operation.
Additional uses of the reply functions:
- Requires no special test devices on site, uses the current equipment
- Reply functions are available at all times
- The end user has access to a test method with clear validity
- The reply functions simplify the initial operation and repair processes; their integration leads to higher test quality and test standardisation
- The recording options of the system make it possible to generate initial operation certificates in an automated manner
- A history can be generated for tested connections
Basic structure of the reply functions
The intelligent reply functions are based on basic services that depend on the nature of the communication network, e.g. voice services (speech, audio, SIP, H.323), fax (G3 und G4) or data (ISDN X.75 or HDLC, IP data services PPP, TCP, UDP).
They are supplemented by additional services such as sub-addressing, user-user information, caller number recognition and forwarding.
The reply functions are based on various basic functions: call only, call acceptance, call-back, compatibility test, call-up of functions, loop functions, etc.
The combination of basic functions, mapped onto the above-mentioned basic and additional services, results in intelligent reply functions that can be directly called by the user. Voice or fax services, which have to be compatible in different networks, can obviously be tested beyond the network boundaries, e.g. ISDN to VoIP and vice versa.
Examples for intelligent reply functions
- Reply functions in audio-test with call-back
- Reply functions with recognition of numbers and services and voice feedback
