Multiple PIMs on a PG can
impact performance, thus
lowering the total number
of agents and IVR ports and
call volume supported when
compared to a single PIM
per PG. There is a
maximum of one PIM per
TDM PG with CTI OS co-
resident.

The maximum indicated is independent from the number of ECC variables used, with each representing approximately 50 bytes
additional storage per record. Note also that with the introduction of selective ECC variable persistence in Unified ICM/Unified
CC 7.1, the maximum includes both persistent and non-persistent variables.
