PathFinder Version 4.22 User Guide19.10 Network Ports – DedicatedOn the overview page, there are three different network port types available on the pop-upmenu. These are:• Network Port 4 wire• Network Port Free Pool• Network Port DedicatedIn our initial simple configuration (section 2.3) we assigned the E1 Network card as a groupof six Free Pool ports. As the name implies, these ports are used on a “first available” basis.If communication between two systems is required, the first available free port will beallocated for the duration of that conversation. Therefore, with a single network card in eachsystem, up to six independent conversations between systems can take placesimultaneously. If a seventh route is requested, the request will be denied. The “speak” keyon this panel will display a flashing red tally, which indicates request cannot be achieved.Operationally this may be unacceptable. There may one or more key persons in theorganisation (e.g. Transmission Director) who must be permitted to speak at all times. Thiscan be accomplished by changing one or more of the Free Pool network ports to Dedicatednetwork port status.19.11 Selecting a key personTo set up a Dedicated Network port, first choose a Free Pool port and change it’s status to aDedicated port.It is beyond the scope of this document to fully explain this process but please note thefollowing;• Initially, the dedicated port need only be assigned at one end of a link• The dedicated port should be assigned to the listening system with a remote target set tothe “key person”.The example below illustrates this. Our configuration for Studio 1 has Remote SystemTargets assigned as shown in section 2.6 on page 13. This shows that Remote SystemTarget 6 corresponds to the MCR manager located on the Central Hub matrix. We will nowdefine the MCR manager as a key person.In the System Overview page, select the row corresponding to the last available Free Poolnetwork port. In our example this is port 12. Right click in the Port type column and chooseNetwork Port – Dedicated. The icon will change as shown below.Trilogy Communications LimitedIssue 1Page 117 of 117
