Step 9: Configuring the Topology-Dependent Parameters

The topology configuration menu is a series of guided questions relating to the deployment of the
SCE 2000 in the network and its mode of operation. Values for the parameters are configured
based on the user answers.
The correct value for each parameter must be ascertained before configuring the system to make
sure that the system will function in the desired manner. (See Topology (on page 3-1) for a
comprehensive discussion of topology and the related parameters.)
Values may not be requested for all topology-dependent parameters, as certain parameters do not apply
Note
to all topologies.
There are six topology-related parameters:

Connection mode: Can be either of the following, depending on the physical installation of
the SCE 2000.
Inline
•
Receive-only
•
Type of deployment: Can be one of the following, depending on the actual deployment:
• Single-SCE Platform: a single SCE 2000 is deployed on one or two SCAS BB Console
links
Cascade: two cascaded SCE 2000s are deployed on two SCAS BB Console links, working
•
as a fully redundant solution.
Physically connected link (cascade topology only): In a cascade topology, the user must
assign an index to each of the links. This index is used to identify the services per link.
In a single-SCE Platform deployment, the indices of the links cannot be changed by the user
and are:
link-0: the link connected to ports 1 and 2
•
link-1: the link connected to ports 3 and 4
•
In a cascade deployment, the user must define which link is connected to which SCE 2000.
The index must be different for each SCE 2000. In this case the user can choose one of the
following:
• Link-0: the link connected to this SCE 2000 is identified as 0.
Link-1: the link connected to this SCE 2000 is identified as 1.
•
Priority (cascade topology only): In a cascade topology, this parameter determines which
SCE 2000 is chosen as the active SCE 2000 in the "active election" procedure. This decision
is taken only when both SCE 2000s are starting up together. If there is one working SCE 2000
and the other is just starting up, then the working one will automatically be chosen as active
and the other one as standby. This parameter can be set to one of the following:
• Primary
