metropolitan-area networks (MANs).
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 2912-LRE or 2924-LRE XL Layer 2-only switches also can be used as residential
