Figure 8 is a typical 2.048 Mbps E1 application of the

LXT301Z. The LXT301Z is shown with a typical E1/

CRC4 framer. Resistors are installed in line with the trans-

shielded twisted-pair lines. As in the T1 application Figure

7, this configuration is illustrated with a single power sup-

and RLOOP are individually controllable, and the LLOOP

and RLOOP lines are also tied to a single control for the

Reset function.
