Abstract
A buffer having a predetermined number, M, of input ports adapted for connection to one of a plurality of devices. The devices have different numbers, P, of ports, where P is less than, or equal to, M. The buffer includes a processor for determining the number of ports, P, of the one of the plurality of devices connected to the M ports of the buffer. The buffer couples the P ports of the device to M output ports of the buffer in a ratio of [M/P] sequences. A method for determining the number, P, of transmit/receive ports of one of a plurality of devices. After connecting one of the plurality of devices to the buffer, a predetermined pattern of data is placed on each of the output ports when the connected device is in a loopback mode. The pattern of data is detected at the input ports in response to the predetermined data placed on the output ports. The predetermined pattern on the output ports is compared with the detected pattern to determine the number of ports, P, of the connected one of the devices.
