4 avOIDINg SINgLe POINT OF FaILURe (SPF) ISSUeS 4.1 SPF Overview Critical network configurations (such as those trans- porting audio signals) should avoid “Single Point of Failure” (SPF) scenarios to the greatest extent possible. SPF failures can occur when a network has been designed in such a way that failure of a single part of the network can cause the entire network to fail or cease operation. -
Page 7: Signal Type Redundancy
4.1.1 Signal type redundancy Use of this topology allows a PLM to receive audio and control signals from a source device using differ- ent output types, i.e. a device which can output both analog and AES signals simultaneously. These signals are then designated as priorities in the auto input section. -

Page 9: Star Or Hub-And-Spoke Networks
5.2.2 Star or Hub-and-Spoke networks An alternative approach is to implement a network with Star topology, also referred to as ‘hub-and- spoke’ or ‘radial’ topology, using a number of Ethernet switches. (See figure 5.2.2.) In such a network, a group of PLMs (typically those inside the same rack) are connected directly to a switch also housed in the rack. -

The following definitions will help the user better understand some specific terms used in this guide, and in other PLM Series technical documentation. Lab.gruppen has made every effort to make sure that the information here is correct and accurate.
