1. A method for managing a network comprising one or more network elements (NEs) each of which is capable to provide one or more circuit cross connects, each cross connect switching an input signal received from a network onto at least one output signal transmitted to the network, the method comprising:
- a first computerized network management system (NMS) receiving, from the one or more NEs, cross connect information regarding the one or more cross connects on the one or more NEs and/or circuit information regarding the one or more circuits passing through the one or more NEs;
the first NMS using the cross connect information and/or the circuit information to manage circuits on the one or more NEs;
the first NMS receiving a command to delete a circuit “
C1”
;
the first NMS issuing a command to at least one NE “
NE1 ”
through which the circuit C1 passes, to remove the circuit'"'"'s cross connect “
XC1”
from the NE NE1;
the first NMS using the cross connect information received from the NE NE1 to determine that the cross connect XC1 has not been removed; and
then the first NMS issuing a command to the NE NE1 to delete the cross connect XC1.

Abstract
A network management systems (NMS) queries network elements (NEs) and receives information on cross connects set up at the NEs and other circuit information. Multiple NMS systems can manage the network at the same time. If one NMS changes a cross connect on an NE, the NE will inform the other NMS systems. The cross connect information is used to provide up-to-date information on circuits set up in the network and to facilitate elimination of “orphaned” cross connects which should have been deleted but have not been deleted due to some network failure.
