Multidwelling Network Using Catalyst 2950 Switches
A growing segment of residential and commercial customers are requiring high-speed access to Ethernet
metropolitan-area networks (MANs).
Figure 1-7 shows a configuration for a Gigabit Ethernet MAN ring
using Catalyst 3550 multilayer switches as aggregation switches in the mini-point-of-presence (POP)
location. These switches are connected through 1000BASE-X GBIC ports.
The resident switches can be Catalyst 2950 switches, providing customers with high-speed connections
to the MAN. Catalyst 2900 LRE XL or 2950 LRE Layer
2-only switches also can be used as residential
switches for customers requiring connectivity through existing telephone lines. The Catalyst LRE
switches can then connect to another residential switch or to an aggregation switch. For more
information about these switches, see the Catalyst 2950 Desktop Switch Hardware Installation Guide.
