T1/E1/CEPT/ISDN-PRI TRANSFORMERS
Quad Port T1/E1 with 8 Transformers, 1500 Vrms
A. OCL (primary inductance) is measured at the primary winding. Turns ratio is
B. To make a 1CT:1 ratio from a 1CT:2CT ratio, use only one-half of the secondary
C. It is possible to use the same transformer model for the three impedance levels
D. Dual Ratio Transformer (T1071NL and T1145NL) — These transformers have

primary winding and connect the secondary pins listed below to obtain desired
turns ratio:

Inductance) for the primary winding) is specified at both -40°C and +25°C. At
-40°C, OCL is 600 µH minimum. All other parameters are specified at +25°C
only. Standard temperature range is 0°C to +70°C
