Figure 7-1. Basic Interface
NOTES:
1) All resistor values are ±1%.
2) In E1 applications, the Rt resistors are used to increase the transmitter return loss (Table 7-1). No
return loss is required for T1 applications.
3) The Rr resistors should be set to 60
each if the internal receive-side termination feature is enabled.
When this feature is disabled, Rr = 37.5
for 75 or 60 for 120 E1 systems, or 50 for 100
T1 lines.
4) See Table 7-1 and Table 7-2 for the appropriate transmit transformer turns ratio (N).
