Space Diversity Protected Co-channel Ring Links
Figure 3-66 illustrates space diversity protection of co-channel ring links.
• Where path protection of a ring link is required space diversity (SD) is
recommended.
• One or all ring links can be SD protected.
• Where co-channel ring links are to be SD protected, both must be SD protected.
• SD protection is subordinated to the ring protection mechanism (ring wrap and
unwrap). For guidance on SD protection of ring links refer to 1+1 Protected
Ring Links on page 3-86.
• The link maximums on single gateway rings are 64xE1 or 84xDS1.
• An NPC plug-in is included in each INUe to provide NCC redundancy.
