Abstract
Line termination units having dual ports for accepting communication traffic of two different types facilitate the concurrent transmission of voice traffic, serial data traffic and packetized data traffic across a telecommunication transport system, such as a DSL (digital subscriber line) system. The bandwidth of the telecommunication transport system is allocated between the differing traffic types to permit the full utilization of the available bandwidth.
Claims18
A termination unit for use in a digital subscriber line system, comprising:
- a first communication interface adapted for receiving first traffic having a bandwidth;
- a second communication interface adapted for receiving second traffic different from the first traffic;
- and
- a third communication interface for coupling to a digital subscriber line;
- wherein the termination unit is adapted to combine the first traffic received at the first communication interface with the second traffic received at the second communication interface, thereby generating a combined traffic, and to provide the combined traffic to the third communication interface;
- and
- wherein the combined traffic has a bandwidth greater than or equal to the bandwidth of the first traffic.
A termination unit for use in a digital subscriber line system, comprising:
- a first communication interface adapted for receiving first traffic having a first number of timeslots, each timeslot corresponding to an incremental bit rate, wherein a number (N1) of timeslots used for payload is less than or equal to the first number of timeslots;
- a second communication interface adapted for receiving second traffic, wherein the second traffic has a bit rate equal to some multiple (N2) of the incremental bit rate;
- and
- a third communication interface for coupling to a digital subscriber line and for providing a combined traffic having a second number of timeslots, each timeslot corresponding to the incremental bit rate, wherein the second number of timeslots is greater than or equal to N1+N2;
- wherein the termination unit is adapted to map the timeslots of the first traffic to a first portion of the timeslots of the combined traffic;
- wherein the termination unit is adapted to map the second traffic to a second portion of the timeslots of the combined traffic.
A method of communicating across a digital subscriber line system, comprising:
- receiving a first traffic having a bandwidth;
- receiving a second traffic different from the first traffic and concurrently with the first traffic;
- combining data of the first traffic with the data of the second traffic, thereby generating a combined traffic;
- and
- providing the combined traffic to a digital subscriber line of the digital subscriber line system.

- combining the first traffic and the second traffic to generate a combined traffic having a second number of timeslots, each timeslot corresponding to the incremental bit rate, wherein the second number of timeslots is greater than or equal to N1+N2;
- mapping the timeslots of the first traffic to a first portion of the timeslots of the combined traffic;
- and
- mapping the second traffic to a second portion of the timeslots of the combined traffic.
