Installing a Ring Network

3DB 23063 ADAA - Rev 004 July 2007
There are no special hardware installation requirements for a ring network. The
main points to note are:
• Each radio link in a ring must be functioning correctly to attain normal,
unwrapped ring operation.
• The RAC plug-ins must be located according to standard INU/INUe protection
rules:
• For an INU, the partner RACs can be installed in any slot. Slots 1 and 2 are
recommended slots for standardization purposes.
• For an INUe, the partner RACs must be installed in slots 1 and 4, or 2 and
5, or 3 and 6.
• Where a DAC 16x is required, it should be installed in a slot on the right side
of an INU/INUe to facilitate easy trib cable management (cable exits its
connector to the right side).
• The protection mechanism is selected in the CT Configuration > Protection
screen.
• Individual links within a ring will be installed and put into operation before the
link is closed. Until all links are operational, circuits configured on the network
will remain wrapped at nodes either side of ring sections still to be completed.
