Method for monitoring the through-connect paths for information transmitted in the form of data bytes in digital time-division multiplex switching equipment

A method for monitoring through-connect paths for information transmitted in the form of data bytes in a digital switching equipment network, comprising steps of:

• assigning at least first and second parity bits to each data byte;
• dividing each data byte into at least first and second parts before their through-connection, the parts of the data bytes being through-connected across parts of through-connect means of the digital switching equipment network that are independent of one another;
• accompanying each of the parts of each of the data bytes by a parity bit that relates to a parity of the other part of the respective data byte;
• and
• providing a reunification of the first and second parts of each of the data bytes with their respective second and first parity bits and then conducting a parity check.
