Flammability — Materials used in these products are recognized as
UL94-VO approved. Products meet the requirements of IEC 695-2-2
(Needle Flame Test).
Balance Characteristics — The transformers meet the requirements
for longitudinal balance of FCC part 68.
Common Mode Rejection Ratio — the CMRR for all transformers is
better than 50 dB at 1 MHz.
Crosstalk Attenuation — In the packages which contain transmit
and receive transformers side by side, sufficient crosstalk attenuation
is achieved by the inherent characteristics of the toroid cores as well
as by their proper positioning. The crosstalk attenuation is typically
65 dB or better.
Return Loss — ITU-T G.703 and the European national regulatory
documents specify minimum return loss levels. The transformers will
allow these limits to be complied within the situations where they
are applicable.

General Information — The transformers are specifically designed for use in
1.544 Mbps (T1), 2.048 Mbps (CEPT) and ISDN Primary Rate Interface (PRI)
applications. They are matched to the majority of the line interface transceiver
ICs currently available. Use of the proper transformer allows the interface circuit
to comply with ITU-T G.703 and other standards regarding pulse waveform,
return loss, and balance.
