2.1 Interfacing the Receive Section to the Line
The design of the XRT59L91 device permits the user
to transformer-couple or capacitive-couple the Re-
ceive 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
Receiver (of the XRT59L91 device) to the line.
