The maximum bandwidth possible between the IPR and ACS-FRS cards is 62 time slots
provided on the internal buses “A” and “B.”
The “C1” and “C2” ports of the FRS card cannot together be assigned more than 32 time slots
due to hardware limitations. The same is true for the FRS ports “C3” and “C4”. A total of 64
time slots can be assigned all the “C” ports. A similar limitation exists for the ports 1-64
terminating the voice circuits. Each group of 32 ports, 1-32, and 32-64 share a common
internal pipe limited to 32 time slots each. The maximum number of time slots allows per port
is one when all ports per group is active. If half the number of ports of a group is active, twice
the number of time slots can be assigned per port.
The maximum internal bandwidth between FRS cards and HSU cards of an Integrated Access
System is limited by the pools size of 126, but also limited by usage from this pool by the
IPR/FRS connections and possible voice card usage.
