A network element of a cable television (CATV) network, comprising an input for upstream signal transmission; one or more diplex filters (210, 212, 214) connectable to said input, the diplex filters (210, 212, 214) comprising bandpass filters for different upstream and downstream frequency bands; a plurality of components arranged to form an upstream signal path, wherein at least one of said components is an upstream amplifier (206c); means (216) for detecting a type of the diplex filter connected between said input and the upstream signal path; means (216) for determining a control signal for adjusting bias current of the upstream amplifier (206c), wherein the control signal is based on at least a type of the diplex filter; and means for adjusting the bias current of the upstream amplifier (206c) based on the control signal.
A network element of a cable television (CATV) network, said network element comprising
The network element according to any preceding claim, wherein said network element comprises means for determining temperature compensation for gain and slope of the upstream amplifier based on the type of the diplex filter.
The network element according to any preceding claim, wherein said network element comprises means for determining the channel load on the upstream frequency band, wherein the control signal is further based on at least the channel load.
The network element according to any preceding claim, wherein the control signal is further based on a difference between an actual input level and a nominal input level of an upstream receiver of upstream amplifier.
The network element according to any preceding claim, wherein the network element is configured to store a plurality of predetermined performance configurations for determining the control signal.
The network element according to any preceding claim, wherein the at least one amplifier unit is the last amplifier unit of the network element in upstream signal path.
The network element according to any preceding claim, further comprising a user interface means for determining the control signal for adjusting the bias current of the upstream amplifier.
The network element according to any preceding claim, wherein said means for determining a control signal for adjusting bias current of the upstream amplifier comprises a control circuit configured to detect at least the type of the diplex filter and to adjust the bias current of the upstream amplifier based on the control signal.
