Technical specifications Connect Ethernet

Delivery of junction

Connect Ethernet is offered as both UNI-UNI and UNI-NNI type connections.

The transmission between two transfer points on the basis of the defined connection features is defined as a connection. We distinguish between UNI-UNI and UNI-NNI type connections.

• UNI-UNI

A UNI-UNI type connection is a dedicated connection between two transfer points/ physical interfaces. The transfer interface at the transfer points depends on the chosen cegecom product. Transmission takes place transparently and at the defined quality.

• UNI-NNI

With a UNI-NNI type connection individual connections are transferred to a NNI (multiplex connections on NNI type). Transmission takes place transparently and at the defined quality. The transfer point at the remote end / site of the connection is formed by a UNI interface.

Additional services

In accordance with the agreement and within the scope of existing technical and operational possibilities cegecom will provide the following additional services for an additional charge:

Redundancy

Service availability in the event of failures of individual components can be secured by duplication of these components at the connection point. Other redundancy scenarios are possible, depending on availability requirements: double end-device, double power-unit, double access-line, double house lead-in permanent 2-way-routing; etc.

These are not part of the product and must be commissioned by the customer and planned by cegecom separately following individual advice and inspection of the premises.

Encryption

To protect your network against a “man-in-the-middle attack” it is possible on request to encrypt the connection. Connect Ethernet 256 bit AES (Advanced Encryption standard) encryption is based on the Diffie-Hellman key-agreement protocol. It stands out in particular for the protection of complete user data, including headers and checksums. Every Bit transferred is encrypted, so there is no attack surface for data theft.
