Figure 85. DPLL Implementation on Active Ports

Note

Since the jitter is removed from the signal before entering the backplane, the signal received from the backplane would only have a small amount of jitter accumulated on the backplane.

The signal received from the backplane goes through the narrowband PLL before being transmitted out of the port.

The passive module switching modules do not use DPLLs on each port. Instead, a Jitter Attenuation Daughter Card (JADC) is required which implements an enhanced DPLL function which can receive and eliminate a greater amount of accumulated jitter.

Note

Ports 17 and 18 on the 18-port active modules can be set up as either RI/RO or lobe ports using the jumpers provided on the module. When these ports are configured as RI/RO ports and your 8260 is connected via these ports to a non-8260 hub, a JADC must be installed on these modules to ensure that the jitter accumulated on the non-8260 hub, is reduced before it enters your 8260.
