Abstract
An infrastructure exchange (,) has a cross-point switch that is arranged to couple data transmission between subscriber terminals (,), each having a dedicated modem (,), and at least one assignable modem (,) located in the infrastructure exchange (,). The infrastructure exchange (,) comprises fewer assignable modems than a combined number of dedicated modems within the subscriber terminals (,) and, since the cross-point switch (,) is responsive to the data transmission sent via the modems of the subscriber terminals, the cross-point switch (,) thereby acts to concentrate a ratio of dedicated modems to assignable modems.
