Implementation and evaluation of a 4-Mb/s twisted-pair transmission system which is proposed as an IEEE local area network standard (802.9) are presented. This standard will provide a multimedia, departmental integrated voice and data LAN (IVDLAN). It is shown that a PR4 line code is optimum for transmission through ordinary laid telephone grade twisted pair. A low-cost transceiver adopting recently developed logically decided timing extraction (LDT) is proposed. 4-MB/s, 450-m transmission using telephone grade twisted pairs is achieved in the presence of crosstalk and impulse noise.<<ETX>>
