2Example 2: Re-configuration required
A similar application as in the last example, but there are 1600 non-
CLASS sets in group 1.
Solution:
The same number of CMOD units (17) is required, since the number of
equivalent CLASS sets (900) in the system is the same.
Equip the 17 CMOD units in group 1, since the XCMC pack should be
equipped in the group with most CLASS (equivalent) sets.
The number of total equivalent sets in group 1 is 2400 (=1600+200x4)
which is greater than the 1760 threshold in Table 38 for a two-group
system.
The customer will have a number of alternatives to resolve the junctor
blocking issue, depending on the situation:
Move the 100 CLASS sets from group 0 to group 1, or
Equip the 200 CLASS agent sets and the XCMC pack in group 0, or
Move 640 non-CLASS sets (=2400-1760) from group 1 to group 0
to avoid threshold violation, or
Move 100 CLASS sets from group 1 to group 0 and split the 17
CMOD units to 10 for group 0 and 7 for group 1; however, this will
require another XCMC pack to be equipped in group 0, or
Move 160 trunks with COI to agent sets from group 0 to group 1, so
that the total equivalent sets in group 1 will become 1760
(=1600+(200-160)x4), since this way the 160 trunks and an equal
number of agent sets will not generate traffic to junctors.
The final decision depends on the specific situation of a site.
