Call progress information in cable telephony
View Patent ↗A method, carried out in an arrangement having a cable that provides programming information to a television monitor as well as telephony service, where call progress information of a telephone call is displayed on the monitor of the television monitor, and the method sends control information upstream, over the cable, in connection with desired information relative to the call progress.
1. An arrangement comprising a cable, a plurality of broadband interface modules connected said cable, and a head-end module tat couples said cable to PSTN network, where each of said broadband interface modules includes a first port for connecting to a television monitor and a second port for connecting to a telephone instrument, the improvement comprising:
said broadband interface module
(a) determines whether information arriving relative to a call that is incoming for said telephone instrument meets a preselected sufficiency level,
(b) when said determination concludes that the preselected sufficiency level is not met, sends a query upstream, via said head end, to obtain additional information,
(c) accepts said additional information to complement said information arriving relative to a call, and
(d) displays said information arriving relative to a call, as complemented, said first port.
2. The arrangement of claim 1 where said first port of each of said broadband interface modules is incorporated in an Ethernet interface for coupling to said television monitor.
3. The arrangement of claim 1 where in step (b) the query is sent to an SS 7 network that is employed to control the PSTN.
