Abstract
A fixed cellular system including a telephone unit, interface and a fixed cellular terminal is disclosed. A telephone unit enables the generation of a sequence of digits in response to a user input. The sequence of digits are forwarded to a system interface wherein a send command is attached to each digit generated by the telephone unit. The digits with attached send commands are forwarded to a fixed cellular terminal responsive to the send commands such that receipt of a send command delays initiation of calls to destinations associated with the sequence of digits for a predetermined period of time.
