The multimedia central office, in use, transceives audio, video and digital data signals for providing at least switching functions originating at or destined for at least one user workstation, to and from the first premises network to provide video communications services. The central office further is coupled to at least one other workstation, not associated with the first premises network, and is configured to combine captured video images, of at least three users including an image from a workstation in the first premises network and an image from a workstation not in the first premises network, into a mosaic image for reproduction at a workstation of at least one user.
