3Example 3: Mixed sets, trunks in both groups and re-configuration
required
A two-group Meridian 1 system serving a call center is expected to equip
200 administrative CLASS sets in group 0 and 400 CLASS agent sets in
group 1. 500 trunks carrying incoming traffic to agents are located in
group 0, 60 trunks serving local CO non-ACD traffic are equipped in
group 1. Assume that group 1 is also equipped with 300 non-CLASS sets.
Can this configuration meet engineering rules? How many CMOD units
are needed?
Solution:
The equivalent CLASS sets in system = 200 + 400x4 = 1800. From
Table 39, 27 CMOD units are needed. It requires the XCMC pack to be
equipped in group 1.
When we equip the XCMC pack in group 1, there are three violation of
rules: (1) the number of CLASS sets in the group without CMOD units
(group 0) is greater than 100, (2) the number of agent sets in a group
without incoming trunks (group 1) is 400 which exceeds the 200 per
group limit, and (3) the violation of threshold in Table 38 for group 1
(=400x4+60x4+300=2140>1760). Several alternatives are available to
make this configuration meeting engineering rules:
Move 100 CLASS sets and 400 incoming trunks from group 0 to
group 1; all above 3 violations are removed by this re-configuration:
(1) CLASS sets in group 0 is 100, (2) 400 CLASS agent sets and 400
incoming trunks with COI are in the same group (group 1), (3) the
number of equivalent sets in group 1 for threshold check-off is
reduced to 640 (=100+60x4+300=640) which is certainly within the
limit (1760).
However, it is impractical to put almost all trunks and agent sets in
one group (group 1). With so many rule violations, the most realistic
approach is to move 200 CLASS agent sets to group 0 and equip
approximately 15 CMOD units in group 0 and 12 units in group 1.
