8.21 AE 905S Module
Description
Existing core network devices, which do not support 1588, cannot obtain clock signals from
BITS servers. Upgrading core network devices to support 1588 is both complex and costly. To
address this issue, the AE 905S module is developed. After having an AE 905S module
equipped, the NE20E will be able to support 1588v2. Figure 8-20 and Figure 8-21 illustrate
the appearance of an AE 905S module.
