In configurations that use a third-party radio as the slave unit, the following must
be configured on the slave unit:
•
The unit’s switching mechanism must be set to Pipe mode
•
Automatic State Propagation must be enabled
•
Flow Control must be enabled
•
A Pipe service must be configured between the Ethernet port connected to
the IP-20
E and the slave unit’s radio or radio group
Note:
The latency differential between the IP-20E and the slave unit cannot
be more than 1.6 ms. That means that under all foreseeable
conditions, such as a high ACM profile on one unit and a low ACM
profile on the other unit, there should be no more than a 1.6 ms
difference between the latency of the two radio carriers in the
Multiband link.

illustrates a configuration that includes SyncE and management for the IP-20C via
the IP-20E. Both of these items are optional, and requires an optical cable
between Eth3 on the IP-20E and Eth3 on the IP-20C, as described in the following
sections.
