Abstract: A method of exchanging data between a primary system, such as a call processing system, and an external system to ensure transactional reconciliation between the systems, the method comprising the steps of creating a data message containing updated data within one of the systems, storing the data message within the system that created the data message, sending the data message to the other system, reading the data message within the other system, sending a receipt acknowledgment message to the system that sent the data message, and modifying data within either one or both of the systems according to the updated data contained within the data message.

Abstract: The display apparatus 2 comprises a cascading display device 4 which defines three elongate channels 6, 8, 10 in which articles, for example magazines or newspapers, may be arranged and displayed. The display device 4 is supported by a support device 12 which extends between a rear wall 14, situated behind the device 4, and the display device and is arranged to support the display device against downwards movement. The support device includes a support flange 78 which extends into a gap defined between limbs 34, 36 of respective channels 6, 8. Support rods 16 extend between the wall 14 and the display device 4 and are arranged to space the display device 4 from the wall 14; to prevent the display device 4 from pivoting about the support device 12; and to add rigidity to the display apparatus. In another embodiment, a support device is provided which includes support flanges which extend into respective gaps defined between the first and second channels 6, 8 and the second and third channels 8, 10.
