“…Since nonblocking multiconnection networks require expansion in the first stage and concentration in the last one we can form various expansion and concentration modules made of square switches (available DSMs are usually square) by using the method proposed in [8]. In some practical applications other approaches to multiconnections may be justified [11], [15].…”

In the paper we study the conditions under which multiconnection networks are nonblocking. A multiconnection network deals with the connections of pairs {{T\,Ti)} where T\ is a subset of the input terminals and Ti is a subset of the output terminals. We investigate networks composed of digital switching matrices. Such networks can be treated as a very general case encompassing many kinds of networks used in practice as well as studied theoretically.We present four routing strategies and then develop conditions under which multiconnection networks are nonblocking when each of these strategies is used. We also show that the obtained conditions reduce to known results for some values of network parameters.

“…A special case of multiconnection networks are broadcast networks, in which |7\| = 1. Recently the special interest in multiconnection networks is caused by their application in broadband systems used for the transmission and switching of high bit-rate signals, including TV and high speed data [14], [15].…”

“…Interestingly, with only a few exceptions [YKS86], [F93], [ABC89] this class of switch is not well represented in the literature. Part of the rationale for the development of array switches was that not all of the crosspoints were needed [C53].…”

Switch designs and the uniform distribution traffic pattern that has been the basis of much switch design analysis are discussed. In particular it is shown that head of line blocking is not the major cause of switch and link underutilization. Switch fabric and buffer system input bandwidth tradeoffs are described. For client server applications it is shown that having the majority of switch buffers on the input side of a switch reduces overall switch buffeting.

“…From the economic viewpoint, a TD switch is suitable for a low bearer rate and a SD switch, for a high bearer rate. A TD network at 64 kbit/s with 1024 multiplexed channels [ 121 and a 32 X 32 SD switch for 7OMbitls [13] are currently available. With the progress of T switch LSI, the TD switch will be applicable in higher bearer rate systems.…”

The demand for broadband services is increasing. However, it is very difficult to specify future demand. Under these circumstances, individual systems must be developed to meet varying demands, while each system should have the capability of being merged into a future broadband network.This paper presents broadband network evolution. First, broadband commercial services as well as prospects for future services are reviewed. Next, the present state and trends in technologies for broadband services are described. Finally, an evolutionary approach to broadband ISDN based on the module concept and unified architecture is proposed.
