Attorney, Agent or Firm:
An automated method and apparatus in a telecommunications network for granting, on demand, changes in the custom feature services available for use at the port. The caller is connected to a feature processor which interactively determines, through prompts and responses, the custom feature services desired by the caller differing from those available in the base services then provided to the port. The feature processor modifies the feature keys seen by the telecommunications network from those normal to the port to include those for the features selected by the caller. Activation of termination triggers cause feature services to revert to those base services normal to the port. |

DETAILED DESCRIPTION FIG.
1 is a block diagram illustrating the basic operation of applicant's invention.
Station 1 is one of many stations connected to local switching system 5.
In FIG.
1, station 1 is connected at terminal port 3 over line 4 to switching system 5 which is part of a larger public switched telephone network 6.
Line 4 may be a physical wire line or a wireless transmission path or a combination of signal carriers.
Local switching system 5 is controlled by one or more processors (not shown), each operating under the control of one or more stored programs.
When a call is originated from a terminal port, for example terminal port 3, that terminal port will be assigned a call process 32, i.
e.
, a block of memory for controlling the call.
The call process 32 accesses the static data block 9 for terminal port 3 in switch static data block 7 of the local switching system 5.
The key configuration in static data block 9 defines the available service for terminal port 3, of which a subgroup determines custom feature service availability.
If the static data items 9 do not include a key configuration for a certain custom feature, access to the feature will be denied to the caller from port 3.
While most of the items in static data block 9 are administered by an operating telephone company and cannot be modified by callers, there are some static data items, which I refer to as dialable static data items 11, which can be modified in response to signals provided from the associated terminal port.
Modification is by selection of feature keys which reconfigure the dialable static data items and by creation of a shadow static data block having a desired key configuration cast over the actual static data block key configuration.
By selecting new feature keys, the configurations in dialable static data items 11 are changed, and the menu of custom features is altered allowing the call process to access and provide as part of the service to the terminal port desired custom features, including the addition of new features, modification of existing features, and deletion of features
