ABSTRACT:
In a method for monitoring the through-connect paths in digital switching equipment, the data bytes to be through-connected are divided into at least two halves and are through-connected via parts of the through-connect means of the switching equipment that are independent of one another. At least one of the parts of the data byte is accompanied by a parity bit that relates either to the parity of the entire data byte or to the parity of respectively one of the other parts of the data byte. A reunification of the parts of the data byte and a corresponding parity check occur after the through-connection. Selection or drive errors can also be recognized, and the error location can be localized in this way with a parity check.
