Chapter 3 Cisco SCE8000 Topology and Topology-Related Parameters
Physical Topologies
These issues determine two important aspects of system deployment and configuration:
• Physical topology of the system — The actual physical placement and connection of the Cisco
SCE8000 platform or platforms in the system.
• Topology-related configuration parameters — The correct values for each parameter must be
ascertained before configuring the system to make sure that the system will function in the desired
manner.
Physical Topologies
Following are descriptions of a number of physical topologies that the Cisco SCE8000 supports.
• SCE8000 Interface Numbering, page 3-3
• Single Cisco SCE8000 Topologies, page 3-3
• Dual Cisco SCE8000 Topology (Cascade), page 3-6
• Multi-Gigabit Service Control Platform (MGSCP) Topology, page 3-7
SCE8000 Interface Numbering
The following diagram shows the numbering of the SCE8000 interfaces as indicated in the topology
diagrams in this chapter. The interface numbering is explained as follows:
• The first digit is the slot number (always 3).
• The second digit is the number of the sub-slot or SPA module (0-3).
• The third digit is the number of the interface on the designated SPA module (always 0).
• Interfaces 3/0/0 and 3/2/0 are on the two left-hand SPA modules and are the Subscriber side
interfaces.
• Interfaces 3/1/0 and 3/3/0 are on the two right-hand SPA modules and are the Network side
interfaces.

Single Cisco SCE8000 Topologies
A single Cisco SCE8000 supports both single 10GBE link and dual 10GBE link topologies.
