Topology

Functionality

Forwarding — This is the normal operational mode, in which the SCE 1000 processes the traffic for monitoring and control purposes.

Sniffing — The bypass mechanism preserves the network link, while in parallel allowing the SCE 1000 to process the traffic for monitoring only.

Cutoff — There is no forwarding of traffic, and the physical link is forced down (cutoff functionality at layer 1).

Functionality

The SCE 1000 can serve one of two general functions:

Monitoring and Control — The SCE 1000 monitors and controls traffic flow. Decisions are enforced by the SCE 1000 depending on the results of the monitoring functions of the SCE 1000 and the configuration of the Service Control Application for Broadband or Mobile solution.

In order to perform control functions, the SCE 1000 must be physically installed as an inline installation and the connection mode must be “inline”.

Monitoring only — The SCE 1000 monitors traffic flow, but cannot control it.

Either an inline installation or an optical splitter installation may be used for monitoring only. In the latter case connection mode must be “receive-only”.

Physical Installation

There are two options for the physical installation configuration of the SCE 1000 Platform:

Inline installation (provides control functionality).

Out-of-line installation utilizing an external optical splitte

The physical installation determines the connection mode that should be configured.
