Frame Relay Components - Page 3
A comprehensive look of all the components you need to know about when using Frame Relay. Illustrations and tables provide a crib sheet you'll want to bookmark. From Cisco Press' Network Consultants Handbook.
Suppose that an organization has deployed the speed-dialing scheme illustrated for reference in Figure 15-6 and detailed in the following list:
- The CEO speed-dials 1 to talk with the COO.
- The CEO speed-dials 2 to talk with the VP of Marketing.
- The COO speed-dials 1 to talk with the VP of Marketing.
- The COO speed-dials 5 to talk with the CEO.
- The VP of Marketing speed-dials 7 to talk with the CEO.
- The VP of Marketing speed-dials 9 to talk with the COO.

Table 15-2 provides another view of the Telephone Speed-Dial Network.
Table 15-2
Table 15-2: Telephone Speed-Dial Configuration Table
Site A | Site B | A -> B Speed Dial | B -> A Speed Dial |
COO | Marketing VP | 1 | 9 |
COO | CEO | 5 | 1 |
CEO | Marketing VP | 2 | 7 |
CEO | COO | 1 | 5 |
Marketing VP | CEO | 7 | 5 |
Marketing VP | COO | 9 | 1 |
For the CEO to speak with the COO, the CEO will press speed-dial 1 on the telephone set. However, the COO will see speed-dial 5 on the telephone because that is the local speed-dial assignment given to the CEO, as the speed-dial 1 local assignment on the COOs telephone set is assigned to the VP of Marketing.
If the COO presses speed-dial 1, the VP of Marketing will answer the phone and speed-dial 9 will show on the Marketing VPs phone because that is the local assignment given to the COO.
