A cordless telephone base unit having a dynamically changeable cellular telephone adapter and partially reconfigurable software is provided. The software includes a static portion containing core application software, and a dynamic portion containing reconfigurable driver software for interfacing with an external device such as a cellular telephone. The driver software can be downloaded from a removable cellular telephone adapter. The core software and the driver software each contain interface portions at fixed locations. The interface portions provide for transparent interaction between core application and driver software.

Telephone base unit having dynamically configurable software

The present invention permits access to information stored on a remote device from a local device without requiring that a complete physical copy of the remote information be made. An enhanced and refined hash table permits access to the remote information in order or according to a search key with significant reduction in the memory requirements on the local device even though the remote information is not sorted. Scrolling through the remote data structure without accessing any unnecessary record on the remote device and hence reducing scroll response time is also achieved.
