Available Facilities

This apparatus has been approved for the use of the following facilities:

·Data transmission speeds up to 33.6kbps and reception speeds up to 56kbps

·Operation to CCITT V21, 22, 22bis, 23, 27, 29, 32, 32bis, 34 signalling rates

·Automatic call initiation

·Detection of initial proceed indication (dialtone) and secondary dialtone

·Operation in the absence of initial proceed indication (blind dialing)

·Automatic dialing using dtmf (tone) or loop disconnect signalling (pulse dialling).

·Tone detection of Dialtone, Ring tone, Busy, Equipment busy, Number unobtainable

·Automatic answering

·Stored and Last Number dialing

·Timed break register recall

Any other usage will invalidate the approval status if as a result, the apparatus then ceases to conform to the standards against which they were tested and approved.
