limitation)" (page 503)
The table entry indicates that in a two group system, the second group
is allowed to have 1760 CLASS sets or a combination of CLASS and
equivalent sets without a need to move sets or trunks around to reduce
inter-group junctor traffic. Due to higher traffic, an agent set or a trunk
is counted to be equal to four regular sets. The conversion needs to be
done before using
inter-group junctor capacity limitation)" (page
If the number of equipped sets (CLASS or otherwise) or equivalent sets
(sets converted from trunks and agent sets) is less than the threshold,
the junctor traffic is expected to be low. There is no special engineering
necessary for CLASS sets (other than providing required modems).
Note that the junctor traffic issue can be ignored if each group is fully
equipped with sufficient CMOD units to handle CLASS sets within the
group. It is the attempt to use one XCMC pack to serve multiple groups that
requires special attention to inter-group traffic. As long as CLASS service is
not impacted by a traffic in-balance already existed in the system, it is not
the objective of this engineering guideline to solve that problem.
Once the threshold is exceeded, re-configuration of the system is necessary
to reduce junctor congestion. The detailed engineering rules are given
later in this document.
