Information About Topology-Related Parameters

Information About Topology-Related Parameters

Refer to the following sections to determine the correct values for all topology-related parameters before
beginning run the initial setup of the SCE 1000.

Connection Mode Parameter

The connection mode parameter refers directly to the physical topology in which the SCE 1000 is
installed. Installation is possible in either of the two following modes:
•
•
Default value = Inline
Note
The connection mode parameter is determined by the physical deployment of the SCE 1000 as follows:
•
•

On-Failure Mode Parameter

As described in the section The Bypass Mechanism, the bypass card supports four different modes. The
following two modes are possible when the SCE 1000 is not operational due to platform failure or boot:
•
•
The Forwarding mode enables control of traffic flow and is not compatible with the non-operational
status.

Inline — The SCE 1000 resides on the data link between the subscriber side and the network side,
thus both receiving and transmitting packets.
Receive-only — The SCE 1000 does not reside physically on the data link. Data is forwarded to the
SCE 1000 via an external optical splitter. The SCE 1000 itself receives only and does not transmit.
Bump-in-the-wire installation = Inline connection mode.
External optical splitter installation = Receive-only connection mode.
Bypass — The optical splitter forwards traffic with no intervention of the control application
running in the SCE 1000 platform, but monitoring functions continue uninterrupted.
Cutoff — There is no forwarding of traffic. The link is forced down, resulting in traffic cutoff at
Layer1.
