PathFinder Version 4.22 User Guide19.14 4-wire Network PortsThe third variant of network port is the 4-wire Network port. The 4-wire Network port behavesin a similar way to a copper wire connection from a 4-wire port on System A to a 4-wire porton System B. A typical application would be to connect a Conference in System A to aConference in System B.It is important to note, when assigning a port on the E1 network card as a 4-wire Networkport, the remote system E1 network card must also assign the corresponding port as a 4-wire port. So as an example, the E1 card in system A is fitted in slot 91 – 96 and the fourthport on the card is assigned as a 4-wire port (port 94). Then at remote system end (SystemB) if the E1 card is fitted in ports 31-36, the 4-wire port must be assigned to port 34.19.15 QRS keyThe Quick Response Key (QRS) functionality is provided on panels that have speak keysacross a network link. As always, it is good practice to include a QRS key on control panelsshould space permit.
