Provision cross connections

43.11 Radio to Ring:

Caution: When parallel radio paths exist between two MSS shelves, port segregation
should be provisioned between the parallel radio paths at both ends to prevent a loss of
traffic.

43.11.1 Prerequisites

Radio interfaces and Ring ports must be enabled on the respective card and
Ethernet Ring Protection Configuration provisioning screens.
When making a cross connection between radio card and Ethernet Ring port:
Verify appropriate port segregation is provisioned to prevent message flooding. Port
segregation should be provisioned between parallel radio paths at both ends when
they exist on the NE. When making a cross connection to one of parallel radio ports,
port segregation should also be provisioned between the radio port and all other
parallel radio ports. Port segregation should also be provisioned between the radio
ports and other Ethernet and/or radio ports where connectivity is not desirable.
