8.4.1.1. General Information 
The "network-wide team" is not a separate feature like the CHESE,
but is instead a useful combination of existing independent features
with several very special changes, for example, to fit the user interface
to the CHESE. The basic features used here are:
- Keyset 300 E
- Network-wide call pickup
- Different versions of call forwarding
All network-wide signaling relationships are produced with the feature
"network-wide pickup groups".
