Table 24: Local Clock Parameters When Profile Is Set To: Itu-Telecom-Freq - Alcatel-Lucent 7210 SAS M Configuration Manual

The 7210 SAS sets its local parameters as follows:

Table 24: Local Clock Parameters When Profile is set to: itu-telecom-freq

clockClass
The ITU-T profile is for use in an environment with only ordinary clock masters and slaves for
frequency distribution. The default profile should be used for all other cases.
The 7210 SAS can support a limited amount of configured peers (possible Master or neighbor
boundary clocks) and a limited amount of discovered peers (slaves).These peers use the Unicast
Negotiation procedures to request service from the 7210 SAS clock. A neighbor boundary clock
counts for two peers (both a configured and a discovered peer) toward the maximum limit.

that is selected to be the master clock. The slave clock will request Announce messages from all
peer clocks but only request Sync and Delay_Resp messages from the clock selected to be the
master clock.
