Summary: | In a data communication system, a device for performing a wrap test on at least one line without affecting the other lines that transmit and receive data over at least one multiplex link within time slots allocated to a given line within a given frame. During each time slot, a wrap control bit is set by the communication system to a state that indicates either the wrap test mode or the normal mode of operations. Said bit controls a logic circuit to cause data to be sent either over link or to the receive circuit to perform the test, within each time slot. |
