Dividing the function of wireless handset control from the function of telecommunication call control in a software architecture of a wireless telecommunication system. The wireless handset control function follows the wireless handset as it registers and is handed off from switch node to switch node; the telecommunication call control function remains on the switch node on which the wireless handset first became active and remains on that switch node until the wireless handset becomes inactive. Upon the wireless handset becoming inactive, the wireless telecommunication call control function is transferred to the switch node on which the wireless handset is currently registered.

An integral radio pager within each remote switch of a switching system with all pagers in the remote switches sharing the same paging service number with respect to a public paging service. When a central processor that is controlling the operation of all remote switches performs a maintenance restart operation with respect to one of the remote switches, the central processor requests that the public paging service page the common service number. The central processor also provides the paging service a paging message that defines which remote switch is to respond to the page. Each integral pager is responsive to the page to interrupt an associated remote processor. In turn, each remote processor is responsive to the pager to examine the paging message and only responds if the remote processor finds its own identification number in the paging message. In addition, the remote switches can each have an integral cellular telephone circuit that share a common telephone number thereby reducing the cost of providing the cellular telephone service. When the central processor wants to establish a data communication link with the remote switch via a cellular telephone call, the central processor requests that the public paging service page the common service number and provides a paging message to the public paging service. The paging message defines the identification number of the remote switch that is to respond to the page. A remote processor is responsive to the paging message to set up a data call via the integral cellular circuit to the central processor.

Emulating human faculties of sight, image, and hand control by a testing system to interact with a multimedia switching system. The testing system can control a multimedia video unit by the transmission of infrared command signals emulating a user actuating buttons on a hand-held infrared transmitter unit to verify that the system responds correctly to such actuations. Also, the testing system can analyze quality of images to be transmitted, transmit those images through the switching system via user multimedia video units, receive those signals at other user multimedia video units, and analyze the quality of the resulting video images. Further, the testing system can place varying levels of multimedia traffic through the multimedia switching system. Further, the testing system can test call control performed by the multimedia switching system by utilizing an infrared transmitter unit to place and receive calls. The multimedia switching system utilizes text that is displayed on the multimedia video units to indicate call state. The testing system identifies the text that is being displayed at different states of the call and determines if the multimedia switching system is functioning properly.

Verifying that a correct program is being received and displayed on a television set of a consumer. In addition, video quality is checked to assure that transmission has not degraded the video quality. When the consumer requests a program by transmission of a message via a controller in a set top box to a system computer controlling a cable television system, the system computer sends the necessary commands to cause the requested program to be communicated to the consumer site and also transmits to the controller in the set top box a start time of the requested program and information defining the initial video content of that program. At the start time, the controller verifies that the initial video content is being received and that the consumer has the set top box correctly tuned. The controller uses a frame grabber circuit at the consumer site to grab the initial portion of the program and then to analyze the stored portion with respect to the initial video content. If the stored portion is not the same as the initial video content, the controller transmits an error message to the system computer. In response to the error message, the system computer corrects the switching or transmission problem so that the correct program is being sent to the consumer site. The system computer then verifies that the correct program is being received.
