Example Network 3
Three PBXs connected by three TIE lines.
Each PBX is connected to two TIE lines, and must be programmed to send calls to each PBX via the
preferred TIE line, however, if the TIE line directly connecting two PBXs (PBX-1 and 2, for example) is
busy, calls between these PBXs can be routed circularly through other PBXs (PBX-1 → PBX-3 → PBX-
2).
Example Network 4
Four PBXs connected by four TIE lines.
Each PBX is connected to two TIE lines, and must be programmed to send calls to each PBX via the
preferred TIE line.
Calls between PBXs that are not directly connected must be routed through another PBX. Also, if the
TIE line directly connecting two PBXs is busy, calls between these PBXs can be routed circularly
through other PBXs. For example, a call from PBX-1 to PBX-4 can be routed as follows: PBX-1 → PBX-
2 → PBX-3 → PBX-4.
