504 CLASS: Calling Number and Name Delivery
A single group system can have as many CLASS sets as each loop allows.
The engineering of the system is not different from that of non-CLASS sets,
since there is no intergroup junctor involved. The only engineering required
is to find the required number of CMOD units from
capacity" (page 504)
Note that the capacity per group for multi-group systems assumes no
trunking in that particular group (or trunks have been converted to equivalent
sets). Therefore, the total system capacity, by taking into account trunks,
agent sets and service circuits, will not be as large as a straight multiple of
number of groups by the number of sets per group.
The number of allowed CLASS sets per group in
sets per group (based on inter-group junctor capacity limitation)" (page
503)
When a system becomes five-group, the junctor capacity is no longer a
bottleneck under the assumption of even traffic distribution. The system
capacity iscome unrealistic if it is purely based on the intergroup junctor
capacity, therefore, other system resources, particularly the system CPU,
need to be checked. The number 4080 is based on loop traffic (28 loops/7
superloops), not junctor capacity.
If a group comprises of both regular sets and CLASS sets, the total number
of sets in the group should not exceed the quoted number in the table. If
trunks and agent sets are included in the group, convert them to "equivalent
sets" before using
inter-group junctor capacity limitation)" (page
described in the engineering guide.
Table 10 "CMOD unit capacity" (page 504)
provides the number of CMOD units required to serve a given number of
CLASS sets with the desired grade of service. The required number of
CMOD units should have a capacity range whose upper limit is greater than
the number of CLASS sets equipped in a given configuration.
