Traduction de «Bit error rate curve » (Anglais → Français) :

After having first been maintained under reference voltage for at least one hour with no current supplied to the circuits, the rated maximum current shall be applied to the current windings. The error of the meter shall be measured immediately after it is put into operation and then at sufficiently short intervals to permit correct plotting of the curve of error ...[+++]variation as a function of time.

Table 1 Current provisions concerning use of cable TV networks for the provision of telecommunications services can be summarised as follows: Use of cable TV networks for liberalised services Belgium No Denmark No France Non-voice services only Germany No Greece ---------* Ireland No legal provision Italy ---------* Luxembourg No legal provision Netherlands Limited use Portugal No Spain No UK Yes Source: "L'impact de l'authorisation de la fourniture de services de télécommunications liberalisés par les câblo-opérateurs", IDATE, 1994, and additional analysis * No cable TV networks available Table 2 Minimum Capacity requirements (approximate) for services Speech: 64 kilo-bits/second ISDN: 140 kilo-bits/second Standard quality moving images: 2 ...[+++] mega-bits/second Enhanced quality moving images: 10 mega-bits/second Table 3 Technical limits on network infrastructure to the home i. Twisted Copper pairs: used by TOs to connect end users to the local switch: up to 257 kilo-bits/second: reliable service to all customers on local network the greater the capacity requirement above 257 mega-bits the greater the trade-offs of increased error rates, lack of reliability and limits on the distance which the end user can be from a central switch.
