6 Maintaining Your System
Swapping Extensions
If a user changes location but wants to keep the same extension number, you
can make the change easily by changing the connection at the control unit.
For example, if the users at extensions 29 and 32 switch offices, you can
disconnect the modular plugs from those extension jacks in the control unit. Then
reconnect the plug from 32 into extension jack 29 and the plug from 29 into
extension jack 32. Now the users can take their respective telephones to their
new locations, keep the same extension numbers, and retain the telephones'
programmed settings.
In some cases, some system parameters may also need to be
changed, i.e., pool extension assignments, when swapping extensions.
