Different services like video-on-demand and Internet Protocol telephony
require different paths with different transmission profiles. Known modem
systems (1) and aggregators (7) select paths by detecting additional
information in packet signals, like in Ethernet the so-called Virtual
Local Area Network (VLAN) tags, and in Asynchronous Transfer Mode (ATM)
so-called (virtual) path identifiers. This disadvantageous additional
information can be avoided by detecting (71) a source/destination address
and, in response to said detecting, selecting (72) a transmission profile
and, in dependence of said selecting, supplying (70) said packet signal
to a path defined by said selected transmission profile. Solely the
source/destination address, like a source address and/or a destination
address, being Ethernet addresses, Internet Protocol addresses or even
port addresses, allow said selecting, which is more efficient. Preferably
a first path is an interleaved path for video-on-demand with a lower bit
error rate, with a second path being a non-interleaved path with a lower
delay for Internet Protocol telephony.
