Features and Services
3 Equip CLASS agent sets in the group where trunks carrying incoming
traffic to agent sets are located.
4 Equip non-agent CLASS sets in the same group as the agent CLASS sets.
5 Equip the XCMC IPE pack on the network group with CLASS sets.
If the system is a single group system, or if above rules are fully met, no
further engineering is necessary.
In case of an existing multi-group site upgrading to provide CLASS feature,
re-configuring the system may be necessary to satisfy rules (3) and (4).
When above rules are not fully met, continue the system engineering by
following the procedure in the next subsection.
Configurations do not fully meet engineering rules (re-
configuration may be required)
When above rules can not be satisfied in a new site or an existing one, the
following guidelines are designed to (1) minimize network blocking, (2)
determine whether a re-configuration (to move trunks and sets around) is
necessary, or (3) whether separate XCMC packs are necessary to serve the
multi-group system.
1 Convert an agent set to regular set by using 1 agent CLASS set = 4 sets.
2 Sum up the total number of equivalent CLASS sets and find the number
of CMOD units required based on the capacity table (Table 39).
3 Equip the XCMC IPE pack on the network group with most CLASS sets
(or equivalent sets).
4 Limit the number of agent CLASS sets to be 200 or less per group.
5 Limit the number of regular CLASS sets in a group without XCMC pack
to be 100 or less.
6 Convert trunks (1 trunk = 4 sets), and agent set (1 agent set = 4 sets) to
equivalent sets before using Table 38 to find junctor traffic threshold.
7 If the threshold in Table 38 is greater than the total number of equivalent
sets, traffic in the system is balanced, there is no need for further network
engineering.
