发明名称 AN ARRANGEMENT IN A TELECOMMUNICATION SYSTEM
摘要 A telecommunication system includes an Internet (1) and a PSTN (2) to which subscribers (S1, S2) are connected via a main distribution frame MDF (41). The subscribers have each a user terminal (10, 20) and a telephone (11, 21) which are connected to the MDF (41) via copper lines (13, 23) and a respective network terminal (12, 22) with a PSTN user modem (16, 26), an xDSL user modem (18, 28) and a splitter/filter (17, 27). The MDF includes a line side device (32) and a station side device (34b), which in turn includes a frequency splitter (51b), a filter (36b) and a modem pool (50b) of high speed modems. Conventionally the modem pool is installed at a separate location, which requires wireing and rewireing. With the modem pool (50b) in the MDF this wireing and rewireing is avoided, which highly simplifies the installation of the modem pool and faulty connection is avoided.
