Figure 1 shows the trunk networking between office A and office D, where the real lines indicate the voice channels.
If two offices have direct voice path, one office is called the office direction of the other. For example, there are direct voice channels between office A and office B, office A and office C, and office A and office D, as shown in Figure 1. It means that office B is an office direction of office A, office C is an office direction of office A, and office D is an office direction of office A. In addition,
because there is no direct voice channel between office B and office C, office C is not an office direction of office B. Also, office B is not an office direction of office C.
In the MSOFTX3000, an office direction is defined by a unique name, so that it can be easily identified. For example, for office A in Figure 1, office direction from A to D can be defined as 1, office direction from A to B can be defined as 2, and office direction from A to C can be defined as 3.

Sub-Route
If a direct voice channel or an alternative channel exists between two offices, it means a sub-route exists between the two offices. The direct voice channel is the direct sub-route and the alternative channel is the alternative sub-route. For example, there are three sub-routes between office A and office D as shown in Figure 1:- Sub-route 1 is a direct sub-route from office A to office D.
- Sub-route 2 is an alternative sub-route from office A to office D through office B.
- Sub-route 3 is an alternative sub-route from office A to office D through office C.
Route
A route is a set of all sub-routes from local office to a destination office. A route contains multiple sub-routes and different routes may contain the same sub-routes. For example, in Figure 1:- The route from office A to office D contains sub-route 1, sub-route 2 and sub-route 3. The direct sub-route is sub-route 1.
- The route from office A to office B contains sub-route 1, sub-route 2 and sub-route 3. The direct sub-route is sub-route 2.
- The route from office A to office C contains sub-route 1, sub-route 2 and sub-route 3. The direct sub-route is sub-route 3.
