The FX II supports a maximum of 32 hunt groups. Each hunt group can include the maximum
number of stations that the system can support; however, due to system memory limitations, all hunt
groups can not contain all stations simultaneously. Since the system makes a total of 32 Kbytes of
memory available for station hunt groups, you can use the following formula to determine possible
station hunt group capacities.
[32768 Kbytes] – [(Stations per group) x (2) + (220 bytes of memory)] = memory remaining for next
hunt group
Station Message Detail Accounting (SMDA)
For details, see the discussion titled SMDA Reports.
Station Message Detail Recording (SMDR)
Station message detail recording provides a record of the incoming and outgoing calls handled by
the system on selected lines. This record provides information for accounting and traffic analysis
studies. When enabled, SMDR is invoked automatically. The SMDR feature generates a call record
for printing as soon as it is collected by the system. The call record is presented as ASCII data in an
eighty-column format to a serial data port located on the CPU board. SMDR requires
customer-provided equipment such as a printer or other compatible data recording device.
SMDR on Transferred Calls
When a system user places a line call on hold, parks it, or transfers it to another station, and another
system user then picks up that call, the system detects the new user, and creates a new record for the
remainder of the call. The system also up-dates the new SMDR field with the initial SMDR field.
Plus, the system up-dates the call duration field and the station number. Further, the system tags the
original call with a T in the call ID field of the SMDR record to indicate that a transfer occurred
during the call.
SMDR on System-Terminated Calls
The system terminates both outgoing and incoming line calls for such problems as toll restriction
rejection or exceeding a call time limit. When the system terminates a call, it up-dates the caller ID
field with the cause of the termination indicated by a tag letter. The various tag letters that can
appear on the SMDR report and their indications are listed in the following table.
