Chain dialling
The chain dialling function is used in more complex telephone services, e.g. for
telephone banking, call−by−call or calling card procedures. Several numbers sto-
red in the phone book can be transmitted when a connection has already been
established. It is also possible to combine numbers for transfer from the phone
book with numbers entered manually. Numbers stored in the phone book can be
chained and transmitted as required.
