The reduction in the jitter would allow you to have longer lobe distances and higher number of station per ring segment. More details about the number of supported stations and the lobe cable length are provided in 8.6, ªActive Port Technologyº on page 142.

The DPLL is used in all the 8260 token-ring modules to ensure that the amount of jitter which enters the backplane has been minimized. This is the case with the passive modules as well as the active modules. However, active modules such as the 18-port active per-port switching module, 18-port active module switching module, and the dual-fiber repeater module implement one DPLL at every port, while the passive modules such as the 20-port passive module, implements just one DPLL at the interface to the backplane. The positioning of the two PLLs on each port of the active module is shown in Figure 85 on page 140.
