Initial System Configuration

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.)

Note Values may not be requested for all topology-dependent parameters, as certain parameters do not apply 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 FE links

•Cascade — two cascaded SCE 2000s are deployed on two FE 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

•Secondary
