45 results about "Channel-associated signaling" patented technology

Channel-associated signaling (CAS), also known as per-trunk signaling (PTS), is a form of digital communication signaling. As with most telecommunication signaling methods, it uses routing information to direct the payload of voice or data to its destination. With CAS, this routing information is encoded and transmitted in the same channel as the payload itself. This information can be transmitted in the same band (in-band signaling) or a separate band (out-of-band signaling) to the payload.

System for and method of channel associated signaling backhaul in a routing system

An open network gateway system for use with networks that do not have dedicated Signaling System No. 7 signaling is provided by associating channel-associated signaling received over a first communication line with individual media channels on a second communication line and embedding channel-associated signaling in a media stream in the form of line supervision signaling and register signaling and using a public switched telephone network line supervision driver to monitor and manipulate line supervision signals and interface to the public switched telephone network dial manager. The associated signaling is then backhauled into a media gateway controller for processing and manipulating the data connection.
