506 CLASS: Calling Number and Name Delivery
When the above rules are not fully met, continue the system engineering by
following the procedure in the next subsection.
Re-configuration may be required (when engineering rules are not
fully followed) When above rule (2) can not be satisfied in a new site or
an existing one, the following guidelines are designed to minimize network
blocking, and to determine whether a re-configuration (to move trunks and
sets around) or to provide an XCMC pack per group is necessary.

The following examples will show some of the engineering details of dealing
with various alternatives.
To simplify discussion, the network group 0 has minor number of CLASS
sets. The majority of CLASS sets are in group 1 (refer to
system with a two-group network" (page
Engineering examples for non-Call Center applications
One XCMC pack serving a single group system No special engineering
rule is needed for a single or half group system (CS 1000M SG, Meridian
1 PBX 61C, and CS 1000M HG). Look up

CLASS sets. For example, to serve a CS 1000M SG with 400 CLASS sets,
use
units serving a range including 400 sets. The result is 10 units which can
serve 333 to 401 CLASS sets.

requirements, consider only CLASS sets (no trunks or non-CLASS sets).
If CLASS sets are equipped in more than one group, locate the XCMC
IPE pack in the group with most CLASS sets.
Use Table 9 "Maximum CLASS sets per group (based on inter-group
junctor capacity limitation)" (page 503)
is required. For a network group with trunks, regular sets and CLASS
sets, convert trunks to sets by using the formula: 1 trunk = 4 sets (called
equivalent sets), and then add up the total.
Check threshold in Table 9 "Maximum CLASS sets per group (based
on inter-group junctor capacity limitation)" (page
equivalent sets is less than 1760 (for example, for a two-group system),
there is no need to re-configure the system.
If the number is greater than 1760, we need to move some of the CMOD
units to a second XCMC IPE pack on another group (when CLASS sets
are scattered in two groups), or move some sets or trunks from one
group to another group to satisfy the threshold.
