Setting the PSN Clock Recovery Parameters
When equipped with a hardware clock recovery component and the required
software license (see
Viewing the License Information
), ACE-3105, ACE-3205 is
able to recover clock streams that are received from the packet-switched
network. A remote PSN clock distribution device, usually located at the BSC/RNC
side, distributes the uniquely-formatted clock streams which ACE-3105, ACE-3205
can recover. The clock recovery parameters are set on the Recovered Clock menu.

To access the clock recovery options:
• From the Clock menu (see
Figure 4-39
), select Recovered Clock.
