In a switching-card architecture, a common switching
card contains all the protection switches for the T1/E1/J1
lines entering the system (see Figures 7 and 8).
With an adjacent card architecture, the switches pro-
tecting any given line card reside physically in the adja-
cent line card (see Figures 9 and 10).
Receive and transmit interfaces reside in the same
board for each T1/E1/J1 port. The diagrams represent
the typical interface transformers and resistors recom-
mended for Dallas/Maxim LIUs, such as the DS21Q55.
The protection switches are placed in the low-voltage
side of the transformer to meet the isolation require-
ments. Note that there is also a TVS in the line side of
the transformers. The receive and transmit resistors pro-
vide impedance matching to the T1/E1/J1 transmission
cable characteristic impedance. Refer to Application
Note 2857 for more information on T1/E1/J1 applications.
