The term "CT" designates a center-tapped winding. Open Circuit Inductance, measured 20 kHz, 100 mV. Leakage Inductance measured across the primary with the respective secondary winding short-circuited. Winding capacitance, formed by the primary and secondary wire. These wires form the "Plates" of this capacitor. Measured at 100 kHz, 20 mV. This is the distributed capacitance. This is the resistance of the windings when measured in DC conditions. The maximum specified unbalanced DC current capability of the device. IDC: The minimum primary inductance and the maximum distributed capacitance satisfy the transmitter output and receiver input impedance requirements of CCITT I.430 for both TE and 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).

This "basic rate access" accommodates two 64 Kbps "B-channels" for information, one 16 Kbps "D-channel" intended for signaling and control, 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.
