1. A communication system, comprising:
- a first communication unit, which is arranged to communicate with a remote communication system over a first communication link having a first, variable data rate; and
a second communication unit, which is arranged to exchange data with the remote communication system by communicating with the first communication unit over a second communication link having a second data rate,wherein the first and second communication units are arranged to modify the second data rate responsively to variations in the first data rate, so as to match the second data rate to the first data rate.

Abstract
A communication system includes a first communication unit, which is arranged to communicate with a remote communication system over a first communication link having a first, variable data rate. A second communication unit is arranged to exchange data with the remote communication system by communicating with the first communication unit over a second communication link having a second data rate. The first and second communication units are arranged to modify the second data rate responsively to variations in the first data rate, so as to match the second data rate to the first data rate.

22. A method for communication, comprising:
-
communicating between first and second communication systems over a cascaded connection of a first communication link having a first, variable data rate, and a second communication link having a second data rate; and modifying the second data rate responsively to variations in the first data rate, so as to match the second data rate to the first data rate. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42)

43. A communication network, comprising:
-
a first communication system, comprising; a first communication unit, which is arranged to communicate over a first communication link having a first, variable data rate; and a second communication unit, which is arranged to communicate with the first communication unit over a second communication link having a second data rate; and a second communication system, comprising; a third communication unit, which is arranged to communicate with the first communication unit over the first communication link; and a fourth communication unit, which is arranged to send data to the second communication unit via the first and second communication links by communicating with the third communication unit over a third communication link having a third data rate, wherein the first, second, third and fourth communication units are arranged to modify at least one of the second and third data rates responsively to variations in the first data rate, so as to match the at least one of the second and third data rates to the first data rate. - View Dependent Claims (44, 45, 46, 47)
