Telco Services
To use the PathBuilder WAN functionality, you must buy lines and services
from a telecommunications company (Telco). Services include but are not
limited to dial-up lines, leased lines, and packet-switched services.
Dial-up
lines allow you to dial your destination when necessary and hang
up when you no longer need the connection. A
leased
line is always
available between two locations. Dial-up lines use the Point-to-Point
Protocol (PPP). Leased lines typically use either PPP, Frame Relay, or X.25.
Packet-switched
services, like Frame Relay, use a combination of leased or
dial-up lines with Telco-owned switching. Typical protocols used over
packet-switched services are Frame Relay, X.25, and SMDS.
Table 3 and Table 4 describe the dial-up, leased, and packet-switched
services supported by the PathBuilder S5xx series switches.
