Configuring SyncE in a Multiband Node
SyncE can be used in Multiband nodes. In Multiband nodes that consist of an IP-
20E and an IP-20C or IP-20S, SyncE can also be configured for the IP-20C or IP-20S
via the IP-20E. SyncE for the IP-20C or IP-20S requires an ESS hardware version for
the IP-20C or IP-20S (two SFP ports).
In CeraOS 10.5, SyncE for the IP-20C or IP-20S requires an optical cable between
port Eth3 on the IP-20E and Eth3 on the IP-20C or IP-20S. Since Eth2 and Eth3 on
the IP-20E are accessed via a single gland on a single physical port, a special cable
must be used. This cable fits into the single gland on the IP-20E in order to
connect to both Eth2 and Eth3. On the IP-20C or IP-20S side of the cable, the cable
is split so that a separate cable can be inserted into the gland for Eth2 and the
gland for Eth3. This is the same cable and the same setup used for inband
management via the IP-20E. For details, see
Inband Management via the IP-20E
To configure SyncE on a Multiband node:
1 On the IP-20E, configure three synchronization sources: Eth1, the radio, and
Eth3. Do
not
configure Eth2 as a synchronization source.
2 On the IP-20C or IP-20S, configure two synchronization sources: Eth3 and the
radio. When using Multi-Carrier ABC, configure both radios as synchronization
sources.
In ring configurations, configure priority order in the direction of traffic on the
ring.
