Systems and methods are provided for achieving the benefits of a frequency division duplex (FDD) system as well as that of a time division duplex (TDD) system. For example, switching between two diplexers associated with providing two fixed upstream (US) to downstream (DS) bandwidth ratios can achieve the effects of a variable diplexer by varying the amount of time spent transmitting and receiving data in accordance with the two fixed US to DS bandwidth ratios. As another example, a single fixed bandwidth diplexer can be used to achieve the effects of a variable diplexer by using the respective frequency segments assigned to US and DS traffic for both US and DS traffic. |
