1. An emulator apparatus for emulating a digital cross-connect switch network to allow testing of a communication network monitor and control system (MCS) in the presence and absence of a selected network failure, the emulator apparatus comprising:

  • a communication module which communicates with the MCS over at least one emulator control link using a communications protocol substantially identical to a communications protocol used in the digital cross-connect switch network to communicate to the MCS;

    a memory unit for storing emulated network data representative of the behavior and topology of the emulated digital cross-connect switch network in the presence and absence of the selected network failure; and

    a processor coupled to said communication module and said memory unit, said processor sending emulator messages for the MCS to said communication module based on said emulated network data, said emulator messages emulating solicited and unsolicited messages that would be sent from the digital cross-connect switch network being emulated to the MCS in the presence and absence of the selected network failure.
