i2004 sets are engineered similar to existing digital sets (based upon 3500
CCS per Virtual Loop). TDS/Conference circuits are provisioned like
existing digital sets (one TDS/CONF card per half group of i2004 sets).
The recommendation is to use 5 ITG cards per shelf. I.e. 5 ITG cards per
superloop, to eliminate ITG-superloop blocking. Use the following table to
determine the number of ITG cards required to maintain the recommended
capacity:
