An apparatus for connecting adjacent panels includes a first panel and a second panel. Each panel has a connectable edge adapted for connection to a connectable edge of an adjacent panel. At least one first panel interface is disposed on the first panel and at least one second panel interface is disposed on the second panel. Each panel interface is positioned on a surface of the respective panel near the respective connectable edge. First and second interlocking elements are disposed on the respective connectable edges of the panels. The apparatus also includes at least one connector with a base and first and second engaging parts projecting from the base. To connect the panels, the interlocking elements of the connectable edges are interlocked with one another. The connector is mounted to the first and second panels such that the base traverses the connectable edges. The connector is moved such that the first engaging part engages the at least one first panel interface and the second engaging part engages the at least one second panel interface when installed.

The system for monitoring the status of an active secure tunnel of claim 6 wherein the test message is an IPSec tunnel ping. 8. The system for monitoring the status of an active secure tunnel of claim 1 wherein the active tunnel monitor command includes an identification of the secure tunnel to test, and an interval of time that the monitor function is active. 9. The system for monitoring the status of an active secure tunnel of claim 8 wherein the active tunnel monitor command further comprises a time to wait between each tunnel status verification attempt, a number of consecutive failures of tunnel status verification attempts required to determine that the active secure tunnel is disabled, and a payload size of a test packet. 10. The system for monitoring the status of an active secure tunnel of claim 4 wherein a first unidirectional tunnel is used to send an Internet Protocol Security (IPSec) tunnel ping from the first network element to the second network element, and a second unidirectional tunnel is used to send a response IPSec ping from the second network element to the first network element. 11. The system for monitoring the status of an active secure tunnel of claim 1 wherein the active tunnel monitoring logic prevents the transmitting of a test message if the number of bytes received or transmitted in the active secure tunnel has increased since a previous tunnel status verification attempt. 12. A method for monitoring the status of an active secure tunnel between a pair of network elements in a communications network, comprising the acts of: originating and transmitting a test message from a first network element to a second network element using the secure tunnel in response to an active tunnel monitor command; receiving the test message at a second network element and transmitting a response back to the first network element using the secure tunnel; accumulating a number of times that the second network element failed to return a response to each test message during a predetermined time interval; and comparing the accumulated failures with a threshold value to determine if the active secure tunnel has become disabled. 13. The method for monitoring the status of an active secure tunnel of claim 12 further comprising transmitting the active tunnel monitor command from a network management application to the first network element. 14. The method for monitoring the status of an active secure tunnel of claim 12 further comprising generating the active tunnel monitor command at a console interface on the first network element. 15. The method for monitoring the status of an active secure tunnel of claim 12 wherein the secure tunnel is formed from two unidirectional tunnels. 16. The method for monitoring the status of an active secure tunnel of claim 12 wherein the communications network is a virtual private network (VPN). 17. The method for monitoring the status of an active secure tunnel of claim 12 wherein the secure tunnel is an Internet Protocol Security (IPSec) tunnel. 18. The method for monitoring the status of an active secure tunnel of claim 17 wherein the test message is an IPSec tunnel ping. 19. The method for monitoring the status of an active secure tunnel of claim 12 wherein the active tunnel monitor command includes an identification of the secure tunnel to test, and an interval of time that the monitor function is active. 20. The method for monitoring the status of an active secure tunnel of claim 19 wherein the active tunnel monitor command further comprises a time to wait between each tunnel status verification attempt, a number of consecutive failures of tunnel status verification attempts required to determine that the active secure tunnel is disabled, and a payload size of a test packet. 21.
