DS21455/DS21458 Quad T1/E1/J1 Transceivers

10 of 270

The parallel port provides access for control and configuration of all the DS21455/DS21458’s features.

The Extended System Information Bus (ESIB) function allows up to eight transceivers, two DS21455s or

two DS21458s to be accessed via a single read for interrupt status or other user-selectable alarm status

information. Diagnostic capabilities include loopbacks, PRBS pattern generation/detection, and 16-bit

loop-up and loop-down code generation and detection.

* The JTAG function on the DS21455/DS21458 is a single controller for all four transceivers, unlike

the DS21Q55, which has a JTAG controller-per-transceiver architecture.
