Ratio: This is the turns ratio, expressed as “Primary : Secondary”. The term “CT” designates a center tapped
winding.
OCL: Open Circuit Inductance, measured 20 KHz, 100 mV.
LLSec : Leakage Inductance measured across the secondary with the respective primary winding short circuited.
CW/W:Winding capacitance, formed by the primary and secondary wire.These wires form the “Plates” of this
capacitor. Measured at 100 KHz, 20 mV.
CD Pri: This is the distributed capacitance.
DCR: This is the resistance of the windings when measured in DC conditions.
IDC:The maximum specified unbalanced DC current capability of the device.
The minimum primary inductance and the maximum distributed capacitance satisfy the transmitter output and receiver
input impedance requirements of CCITT 1.430 for both TE & NT.
The maximum distributed capacitance allows sufficient margin for the capacitance of the IC and a protection diode
network. It is consistent with the overall maximum value specified and permitted length of the basic access TE cord.
Flammability Materials used in the products are recognized UL94-VO. Products meet the requirements of
IEC 695-2-2 (needle flame test).
Safety Standards All transformers listed in this data sheet are designed to meet UL1459 and UL1950 as a basic
insulation barrier (UL file number E133523).

Application Notes
The S-Interface is the standardized four wire digital telephone
access point defined by the CCITT I-Series recommendations
for the Integrated Service Digital Network. This “basic rate
access” accommodates two 64 Kbps “B-channels” for informa-
tion, one 16 Kbps “D-channel” intended for signaling and con-
trol, and 48 Kbps for framing and other purposes, giving a total
rate of 192 Kbps. The CCITT physical layer recommends that
the user network interface be transformer coupled as shown in
our typical application notes.
