Synchronization For Mpr-E In Single Ne Mode With 7705 Sar - Alcatel-Lucent 9500 User Manual

The source and destination MAC addresses can also be summarized by the following
formula linked to the slot and port number in HEX:
PMC card source MAC address: 00-80-9F-09-F<slot#>-<port#><slot#>
PMC card destination MAC address: 00-80-9F-09-F<slot#>-0<slot#>
For example, for slot number 4 and port number 2:
Source MAC address = 00-80-9F-09-F4-24
Destination MAC address = 00-80-9F-09-F4-04
3.10.15.3 — Synchronization for MPR-e in Single NE mode with
7705 SAR
The MPR-e can be synchronized via either Optical or Electrical interface supporting one of
the following methods:
• SynchE (Synchronous Ethernet) with network clock direction configuration (towards
or from the radio) as follows:
•
•
•
• PCR (Proprietary Clock Recovery
• The MPR-e can also use its internal reference and discard any external
synchronization.
Note: SSM is transparently forwarded in most of the configurations (see the Release
Notice for exceptions).
In a Single NE solution no special configuration is required. Both 7705 SAR and MPR-e
self-detect the port selected and consequently configure the correct synchronization
method.
When copper interface is used either using native RJ-45 or Copper SFP on the PMC
(7705 SAR) side, PCR is selected both by MPR-e and 7705 SAR self-assigning right MAC
addresses.
When optical interface is used, SynchE is selected by both MPR-e and 7705 SAR.
