2.7.2.1 Advantages of Designing a Network using Two IBM 9783s
Figure 16. 254 (127 * 2) Circuit Group using Two IBM 9783s
Figure 16 shows the advantages of having two IBM 9783s. The advantages are:
• It is possible to use maximum 254 circuit group
• Availability of a 9783 is twice that of a single 9783 configuration
See 4.2.5, “Sample Scenario with IBM 9783 and 2212 at Two HQs and 2212 at
Branch Offices” on page 118 for a detailed configuration.
