An object-based data processing system, such as a node for a telecommunications system, has data processing hardware which is capable of performing a plurality of possible functions. Each function is controlled by a respective software object. The object receives instructions to perform the function through interface means (to which the instructions are passed from, for example, an operation zone maintenance centre), and has a respective distinguishing name which is determined in accordance with an interface standard (such as is laid down by ETSI), and which is required in the instructions to that object, wherein the system includes a further software object for causing an additional function to be performed, the further object having a non-standard name which is not revealed in any scoping or searching of the system, or any wildcard addressing thereof. The further software object allows the option for additional functions to be provided by the system, whilst ensuring that the system still appears to comply with said standards, and avoiding the need to update the interface means.
