# Hybrid XNET Programming Example

The following was decided during the network planning:

- Number 101 was assigned to one PBX, 102 was assigned to the other. The PBXs are located in different area codes (416 and 613).

- Both PBXs use a 4-digit numbering plan, extensions on PBX 101 begin with "1", followed by 3 digits. Extensions on PBX 102 begin with "2" followed by 3 digits.

- The expected rate of traffic was estimated and the following DID numbers were purchased:

- 6135552002 - B-channel call from system 101 to system 102.

- 4165551002 - B-channel call from system 102 to system 101.

XNET Networking is enabled by default on Enterprise systems.
