*Note: System blocking will reduce the number of lines that can be handled at this traffic rate so the number of operators will be lower.

The following assumptions apply to the table above:

•Majority of calls handled by the operator are for incoming trunk traffic.

•Calls are answered on average within 10 seconds.

•Calls are handled (transferred/dropped) within an average of 20 seconds.

•85% of all calls are handled within these time limits.

•Table shows recommended number of operators. Local traffic conditions may increase or decrease these values, and hold times may be higher requiring more operators (or vice versa).

•Table shows the quantity of incoming trunk calls handled by operator as 25%, 55%, and 85% of all incoming calls. Remaining calls are handled through direct connection, diversion to voice mail, or IVR equipment (IVR can also be considered as an operator replacement).

•Up to 16 IP operator consoles can be used on the 3300 ICP system.

•As a rule of thumb, operators will typically handle calls at a rate of 50 to 100CPH. The majority of calls handled by the operator are for incoming trunk traffic.
