LUCENT 5ESS DEPLOYMENT
Lucent 5ESS CO switches provide the option to provision all TR-08 units as the standard A, B,
C, and D shelves, or as all shelves being assigned as an A shelf. This is an advantage of this
switch under TR-08 operation. By setting all shelves to the A setting, alarm reporting to and
from the LDS is available on each link to each connected RT. For Lucent 5ESS switches, use
the Shelf A setting on the first RT, and either the Shelf A setting or the Shelf B/C/D setting
on the three remaining RTs. This is depicted on Figure 7-2 below.
