Abstract
A transmission system with a number of tap devices (1), which are connected to a distribution network (9). Subscriber terminals (11) can be connected to each tap device (1) present in a building (10), by means of a private, in-house network (13); these terminals can send upstream signals (AUF) to a center (8). A tap device (1) has first means (4, 5, 6) which attenuate an upstream signal (AUF) supplied to a second port (3) with a specified attenuation factor (a) and send it to the first port (2). The upstream signal (AUF) is sent out by a subscriber terminal (11) with a signal level which is selected so that after the attenuation, the upstream signal (AUF) has a level specified in the distribution network (9).
