CAP keys will not let you direct select the key and make an outgoing call via ars like the loop key will.
You can set the loop key as:
1-Outgoing Only
2- Inbound Only
3- Bothways
CAP keys were a direct result of the old Electr-pro series of having more CO lines available then ther was buttons available on the sets.
Also starting with the old 8/24 and on up they did not have a dedicated intercom/call key.
