摘要 |
An OVPN user registers an L1 signal type information which is used in the user's (20-11) device in an OVPN terminating device (30-1) in advance together with an IP address and a VPNID which are allocated to the user's device (20-11). Registered contents are notified to other OVPN terminating devices (30-2,80-1) which control the same VPNID as that of the user's device. Otherwise, when a calling connection request arrives from the user's device (20-1), the registered contents are notified other OVPN terminating devices (80) which control the devices which receive the notification. By doing this, it is possible to handle a request by the user for changing the setting for the signal format which is employed in the user's device (20-1) quickly. Also, it is possible to realize an OVPN which can perform a process for a calling connection request from the user efficiently and improve an operability for the user. |
