2.1 Interfacing the Receive Sections to the Line
The design of each channel (within the XRT5997
device) permits the user to transformer-couple or
capacitive-couple the Receive Section to the line.
Additionally, as mentioned earlier, the specification
documents for E1 specify 75
termination loads, when
transmitting over coaxial cable, and 120
loads, when
transmitting over twisted-pair. Figures 7 , through 9
present the various methods that the user can employ
in order to interface the Receivers (of the XRT5997
device) to the line.
