Physical Topologies
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 i ndicated 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.
