Abstract: Automatic telephone answering equipment is disclosed which is associated with a telephone set connected to a switching system along with other telephone sets, and the answering equipment functions with central message recording equipment which is also connected to the switching system. Unanswered incoming calls originating from within or without the switching system are answered by the automatic answering equipment which then transfers the call to either another of the telephone sets or to the message recording equipment, as selected by the user of the answering equipment. When the call is transferred to the central message recording equipment the identity of the telephone set to which the call was directed is forwarded to the recording equipment. Only upon the calling party recording a message in the central message recording equipment, the recording equipment uses the called telephone set identity to call the originally called telephone set.

Abstract: A communications line under test intercouples programmable local units, one of which transmits an analog waveform to the other in response to digital control signals received from a computer. The receiving programmable local unit transmits a digital signal to the computer representative of the received analog signal to thereby enable the computer to determine transmission characteristics of the communications line intercoupling the programmable local units.
