Echo cancellation can be used so the downstream channel overlaps the ittu channel, or vice versa, meaning simultaneous upstream and downstream signals are sent. Thanks for any help. Loss-frequency response of channel-translating equipment used in some countries for international circuits. Group-delay distortion performance of terminal equipment.

Please remedy the lack of verification in the article before choosing to renominate. Deletion requests December What should I do? The data frame rate of 4kHz comes from the fact that one includes the overhead of the v extension and the synchronization frame. General aspects of optical fibres and cables. Ethernet linear protection switching with dual node interconnection. As line conditions change, bit swapping allows the modem to swap bits around different channels, without retraining, as each channel becomes more or less capable.
