One XCMC pack serving a 2-group system
1Example 1: No re-configuration
A 2-group Meridian 1 system serving an office is expected to convert 400
analog sets to CLASS sets. Currently, 100 of them are located in group
0, where all incoming trunks are located, and the remaining 300 sets are
in group 1. Assume that group 1 is also equipped with 800 non-CLASS
sets. How many CMOD units are needed to serve this application and
does the customer need to re-configure the switch (move sets and trunks
between group 0 and group 1) to do the upgrade?
Solution:
The table lookup indicates that 400 CLASS sets need 10 CMOD units.
Since one pack provides 32 units, one XCMC pack is sufficient for this
customer.
Group 1 is equipped with 300 CLASS sets which is greater than the 100
sets in group 0, the pack should be installed in group 1.
The total equipped ports in group 1 is 1100 (=800+300). For a 2-group
system, the second group is allowed to have 1760 sets (from Table 38)
without junctor traffic concerns, therefore, there is no need for the
customer to re-configure the switch.
