the ITU-T G.703 Pulse Template Requirements for E1
Applications.
An illustration of the ITU-T G.703 Pulse Template Re-
quirements is presented below in Figure 9.
With input signal as described above, the XRT82D20
will take each mark (which is provided to it via the
Transmit Input Interface block, and will generate a
pulse that complies with the pulse template, present-
ed in Figure 9 (when measured on the secondary
side of the Transmit Output Transformer).

ITU-T G.703 specifies that the E1 line signal can be
transmitted over coaxial cable and terminated with
75
or transmitted over twisted-pair and terminated
with 120
.
In both applications (e.g., 75
or 120
, the user is ad-
vised to interface the Transmitter to the Line, in the
manner as depicted in Figure 10and Figure 11, re-
spectively.
