							Configuration Programming
Various network interface and operation parameters are programmable by the installer, allowing
compatibility with a wide variety of central offices and PABXs. The system is pre-programmed at the
factory; many installations will require few changes to these values. Programming is retained in the CPUs
memory when power is disconnected.
Systems with two attendant positions require programming at both consoles for recall rings and line privacy.
The programming procedures for ring delays, the time of day clock, autodial numbers, and station names
are described in their respective sections.
The following features may be set from configuration programming mode by pressing the appropriate DSS
key. The letters are printed on the console front panel beneath the DSS keys. Key numbers in parentheses
represent the station ports assigned to the keys.

DSS key to select feature:A
Default value:5 sec
This parameter determines the timing for discontinuing ringing
of unanswered incoming calls that were abandoned by the
caller. It should be set to the next time value longer than the
silent interval between ringing bursts.
if too short– each ring burst may be seen as a new call. This
can cause erratic line lamp rates and loss of ringing delays.
if too long– abandoned calls will continue to ring for the
duration of this timing value.
DSS key to select feature:B
Default value:3 rings
This sets the number of rings before a call transferred to an idle
station recalls the console.
Set this parameter according to customer preference.
