Reliability Aspects

Connection Reliability in a Private Leased-line Network
If a network consists of several systems, connection reliability can be increased if
there are two or more paths in each case between two systems.

Fig. 3.52: Each system can be reached in two ways
Routes are used for outgoing routing, as described in "Example of Networking",
Page 3.109.
Route 2 in system 1 for example is used for connections from system 1 to
system 2. In this route trunk group 1 is now added in the first position and trunk
group 2 in the second.
Under normal circumstances calls will be routed directly from system 1 to
system 2 via trunk group 1. If, however, the lines of trunk group 1 are faulty or if
they are all busy, calls will be routed over trunk group 2 via system 3.
