Telecommunications equipment may require network connectivity. On newer systems, an additional local management interface is provided for proprietary maintenance functions, typically via a shell-based Command Line Interface. This is not available on remote sites with only TDM connections. The invention provides a method of communicating between a management console and remote access equipment via a class 4 telecommunications switch, which comprises establishing an IP connection, establishing a synchronous telecommunications transport connection between the class 5 switch and the remote access equipment, setting up a voice call between the management console and the remote access equipment, passing the voice call over the IP connection as a VOIP call, passing the voice call over the synchronous telecommunications transport connection as a PCM encoded call, and encapsulating an IP data stream in the VOIP and PCM encoded call to establish an end-to-end IP.

A finite state machine is provided. The finite state machine causes a function to be carried out in dependence on at least an event input to the finite state machine and the current state of the finite state machine. Associations between the functions that are to be carried out and combinations of the states and the events are identified using an associative array. The associations identified using the associative array are amended while the finite state machine is operating to dynamically reconfigure the operation of the finite state machine.
