Below is a description of the basis for the definition of the features of CONNECT CLASSIC. The technical specifications define the UNI-UNI and UNI-NNI type connections and are based on the relevant standards/norms of ITU-T and ETSI.
CONNECT CLASSIC SDH 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.
| Interface | Transmission made | |||
|---|---|---|---|---|
| Debit | Type | UNI | NNI | |
| N x 2.048 kbit/s | E1 |  |  | |
| 155.520 kbit/s | STM-1 | | | |
| 622 Mbit/s | STM-4 | | | |
| 2,488 Gbit/s | STM-16 | | |
