Private network services

4

EPLAN and EVPLAN are multipoint-to-multipoint (MP2MP) services but they can provide P2MP services. They are used to establish communication channels between multiple organizations. An EPLAN service exclusively uses network resources, while different EVPLAN services share the same network resources.

Private line services are classified into EPL and EVPL services, both of which are P2P services over communication channels between two parties. An EPL service exclusively uses network resources, while different EVPL services share network resources.

How can the TE30 on a private network communicate with a terminal on another private network?
To enable two TE30s on two private networks to communicate, their IP addresses must be mapped to the same IP address on a public network through NAT. For details, see chapter 4 Endpoints on Different Private Networks in the HUAWEI TE30&TE40&TE50&TE60&TX50 Videoconferencing Endpoint Configuration Examples.

How the terminal is configured in a private network during private and public networking
To configure the terminal in a private network, start the NAT and configure the NAT address. The procedure for configuring the NAT is as follows: On the screen controlled by the remote control, choose Settings > Network > IP > Firewall, start the NAT, and set NAT address parameters. Configure the NAT address mapping on the router. For details, contact the router vendor. NOTE: The parameter NAT address is the IP address of the terminal in the public network. By using the network address translation (NAT) technology, a device within the LAN can use a dedicated internal IP address and an external IP address that can be used for the communications with external devices. If the NAT technology is used, set the IP address in the WAN for the terminal.

How do I configure private-public network traversal for the SMC2.0 and SC?
The SMC2.0's built-in SC and standalone SC of V100R003C10SPC900 or later supports traversal between private and public networks. For the detailed configuration procedure, see Configuration for Traversal Between Private and Public Networks.

What are the solutions for traversal between private and public networks on the SMC2.0?
Currently, the SMC2.0 supports mapping and video firewall networks of two network adapters for traversal between private and public networks. For details, see the Configuration for Traversal Between Private and Public Networks.
