The demonstration system used in the examples in this chapter has a small set of tielines that
allow multi-hop routes.
Sample NV9000 Data
The (simple) demonstration setup for tielines has 3 routers, A, B, and C.
The routers are identical in size, each having 16 general inputs and outputs, except that router B
routes SD, not HD. Tielines that perform up- and down-conversion are required between A and
B and between B and C.
Thus, between A and B, there are 4 tielines, AB1 through AB4. Between B and C, there are 4
tielines, BC1 through BC4.
A route from router A to router C (through router B) is a 2-hop route.
The tielines form pool of resources from which the router control system can draw when it
wants to perform routers from A to B, from B to C, or from A to C.
(Routes from C to A, B to A, and C to B are not defined in this demonstration system.)
Sample Tieline Routes
Using the sample system, three tieline routes were made, one from A to C, one from A to B, and
one from B to C:

The route from AIN1 to COUT1 is considered “multi-hop.”
These routes are depicted in the following sections.
