Abstract: A toy vehicle track system of the present application includes electrical connections between the track pieces that allow a central hub, referred to herein as a “portal piece,” to communicate with any track pieces included in the track system. In order to ensure that the portal piece can quickly and accurately identify track configurations that are built, the toy vehicle track system implements a communications protocol that supports communications between any two pieces of track. Based on these communications, the portal piece can determine an orientation, a track type, and a position of any track pieces attached, whether directly or indirectly, to the portal piece. The portal piece can then transmit this information to an electronic device executing an application associated with the track system to allow for digital play on a digital version of the track configuration (among other digital play modes).

Abstract: An apparatus for using multiple call controllers of voice-band calls is provided. The apparatus includes a first protocol endpoint, a second protocol endpoint, and a protocol adapter. The first protocol endpoint is configured to receive at least one first external message from a first call controller and to map the first external message to at least one corresponding first internal call control message. The second protocol endpoint is configured to receive at least one second external message from an integrated access device and to map the at least one second external message to at least one corresponding second internal call control message. The protocol adapter is configured to receive the first and the second internal messages and to route the first and the second internal messages to the appropriate one of the first and second endpoints.
