Program 0401 - System Timers (page 375)
The system-wide timers allow the adminstrator system performance to meet the specific appli-
cation requirements. 
DIL No AnswerThis timer sets how long a DIL rings an idle exten-
sion before Key Ring occurs. Key Ring rings all 
extensions programmed to ring for that line.15 sec.
Trunk RevertThis timer sets how long Hold Recall rings the exten-
sion that placed the call on hold before Key Ring 
occurs. Key Ring rings all extensions programmed to 
ring for that line.
This timer also sets how long a Transfer Recall rings 
the extension that initially transferred the call before 
Key Ring occurs.15 sec.
Trunk Delay RingUse this timer to set how long the system waits before 
ringing an extension that has the Delayed Ringing 
option enabled.10 sec.
Trunk OverflowInformation to be provided. 20 sec.
Centrex Type  Feature 
Key DelayThis timer sets how long the system waits when it 
finds a Centrex delay (i.e., D) programmed in a Cen-
trex Feature Key.50 sec.
ACD/UCD OverflowThis timer sets when UCD overflow occurs. When all 
UCD agents are busy, a queued call rings for this 
interval and then overflows to the UCD Overflow des-
tination.60 sec
Number of Password 
AttemptsUse this option to set how many times the system 
allows a user to enter the incorrect programming 
password before locking them out.3
Program Lockout TimeOnce the system locks out a user, it will wait this 
interval before allowing the user to reenter the pro-
gramming mode.10 sec.
Force Program ExitIf a telephone in the programming mode is inactive 
longer than this interval, the system automatically 
cancels the programming mode and makes the tele-
phone idle.10 sec. Table 11: Program 0401 - System Timers (Page 2 of 2)

OptionDescriptionDefault
Hold Recall
Use this timer to set how long a call stays on Hold 
before it recalls the extension that initially placed it 
on Hold.60 sec.
Exclusive HoldUse this timer to set how long a call stays on Exclu-
sive Hold before it recalls the extension that initially 
placed it on Exclusive Hold.90 sec.
Camp-OnUse this timer to set how long a transferred call 
camps-on to a busy single line phone before recalling 
the extension that initially transferred the call.60 sec.
Call Forward Ring No 
AnswerWhen Call Forwarding Ring No Answer is enabled, 
this timer sets how long a forwarded call rings an 
unanswered extension before routing to the forward-
ing destination.
Also use this timer to set how long a transferred call 
rings a busy operator extension before recalling the 
extension from which it was initially transferred. Note 
that this timer does not control how long a trans-
ferred call rings any other busy extension.10 sec.
Call Waiting Tone  IntervalUse this timer to set the interval between Call Waiting 
tones.
Also use this timer to set the interval between Off 
Hook Signaling alert tones.10 sec.
Call Coverage DelayFor extensions with Delayed Ringing Call Coverage 
keys, this timer sets how long a call flashes the key at 
an extension before it starts to ring.10 sec.
Hook flash TransferThis timer is currently not implemented. 2 sec.
Hook Flash DisconnectThis timer is currently not implemented. 12 sec.

Number of Extended 
RingsIf an extension’s Class of Service enables Extended 
Ringing, use the timer to set the duration of the 
Extended Ringing.20 sec.
Drop Pulse SendUse this timer to set the duration of the ASTU PCB 
drop pulse. This pulse is sent from the ASTU PCB to 
the connected analog device to initiate a disconnect.300 mS
DTMF DetectUse this timer to set the DTMF detection threshold 
for single line (analog device) ports. If the analog 
device sends a DTMF signal longer than this interval, 
the system recognizes it as a valid DTMF tone and 
decodes it. If the DTMF signal is equal to or less than 
this interval, the system ignores it.70 mS
Ring No Answer HuntUse this timer to set the Extension Hunting Ring No 
Answer Time. A call will ring a hunt group member 
extension for this interval before automatically 
cycling to the next extension in the group.10 sec. Table 12: Program 0403 - Station Timers (Page 2 of 2)

Country Data
Use this option to define the country of use and the 
codec digitizing method for ASTU PCBs. This timer 
consists of two bits (xy), with bit x defining the coun-
try and bit y defining the digitization method. For 
example, the default entry 00 is for North America 
(x=0) and u-law digitization method (y=0). Do not 
change this entry from its default value (00).00
(xy)
Rotary Dial TypeUse this option to define the rotary dial pulsing 
method for the system’s ASTU PCBs. Do not change 
this entry from its default value (01).Standard
(0)
Loop CurrentUse this option to set the maximum allowed loop cur-
rent for the system’s ASTU PCBs. Normally choose 
25mA for short loops and 35mA for long loops. In 
general, a long loop is 3000 feet or longer and a short 
loop is less than 3000 feet.25mA (0)
Ringing FrequencyUse this option to define the AC ringing frequency for 
the system’s ASTU PCBs. Do not change this entry 
from its default value (20 Hz).20 Hz (1)
Minimum Break TimeThis timer defines the minimum amount of time the 
loop must be opened to properly decode the dial pulse 
digits sent from analog devices connected to ASTU 
PCBs. Change this value only if the connected ana-
log devices are set to dial at a rate other than 10 
PPS.2 (10 mS)
Maximum Break TimeThis timer defines the maximum amount of time the 
loop must be opened to properly decode the dial pulse 
digits sent from analog devices connected to ASTU 
PCBs. Change this value only if the connected ana-
log devices are set to dial at a rate other than 10 
PPS.20 (100 mS)
Minimum Make TimeThis timer defines the minimum amount of time the 
loop must be closed to properly decode the dial pulse 
digits sent from analog devices connected to ASTU 
PCBs. Change this value only if the connected ana-
log devices are set to dial at a rate other than 10 
PPS.2 (10 mS)
Maximum Make TimeThis timer defines the maximum amount of time the

Default Setting
Refer to the charts above.
Minimum Hookflash TimeFor ASTU PCBs, this timer defines the minimum 
amount of time the loop must be opened before the 
system starts to detect a transfer or hang up sequence. 
Open loop intervals shorter than the setting are 
ignored by the ASTU PCB.21 (105 MS)
Maximum Hookflash 
TimeFor ASTU PCBs, this timer defines the maximum 
amount of time the loop can be opened in order for 
the system to detect a Transfer sequence. Open loop 
intervals longer than the setting are interpreted as 
hang up.200 (1000 mS 
/ 1 second)
Minimum Ground Flash 
TimeFor ground start applications with ASTU PCBs, this 
timer sets the amount of time a ground must be 
applied before the system detects a transfer sequence. 
The ASTU uses this timer when analog telephones 
use ground Transfer instead of open loop Transfer. 
This timer is not used in North America. Do not 
change this timer from its default value.21 (105 mS)
Minimum Off-Hook TimeFor ASTU PCBs, this timer defines how long a con-
nected analog device must remain off-hook before the 
system recognizes the off-hook status.21 (105 mS)
Off-Hook Guard TimeThe ASTU PCB waits this interval after an analog 
device hangs up before accepting any additional input 
from the device. This timer helps prevent erroneous 
detection due to hardware stabilization. 60 (300 mS)
Dial Pulse Guard TimerThe ASTU PCB waits this interval between dial pulse 
digits before attempting to detect any additional DP 
digits. This timer helps prevent erroneous DP dialing 
due to hardware stabilization.70 (350 mS)
Loop Disconnect TimeWhen the far end disconnects, the ASTU PCB opens 
the loop to the connected analog device for this inter-
val.40 (200 mS)
Ring/MW Wait  Period 
TimeThis timer determines the ringing sequence for the 
devices connected ASTU PCBs. Because of power 
consumption, it is not possible to ring all analog 
devices on an ASTU simultaneously. Instead, the card 
is divided into 4 groups with two ports in each group. 
Ringing cycles between the 4 groups, ringing each 
group for this interval.15 (750 mS) Table 13: Program 0404 - Analog Station Timers (Page 2 of 2)

Description
The system provides many trunk timers that the administrator can customize. Review the table 
below for a description of each trunk timer.
Following is a summary of the Program 0402 - Trunk Timers (page 378). Refer also to:
Rules for Detecting Normal CO (Single) Ring on page 304.
Rules for Detecting Special (Double) Ring on page 304.
Rules for Detecting Loop Current on page 305.
 LCCPU 01.00.00 Available.
Customize critical trunk timers for compatibility with the connected telco or PBX/Centrex.

OptionDescriptionDefault
Camp-On
Information to be provided. 60 sec.
Line ResponseWhen the system fails to detect loop current on a 
trunk, it will wait this interval before marking the 
trunk as defective.
Be sure the value you enter is compatible with the 
local telco. If you set this value too short, the system 
may mark properly functioning trunks as defective. If 
too long, defective trunks may be left in service.100
(10 seconds)
Dial Tone  DetectWhen the system seizes a line to place a Speed Dial 
call, it waits this interval for dial tone before outdial-
ing the call. The system requires that the first dial tone 
be at least.5 seconds long and the second dial tone to 
be at least 2.5 seconds long.
Be sure the value you enter is compatible with the 
local telco. If you set this value too short, the system 
may not seize properly functioning trunks. If too 
long, there will be too long a delay before the system 
skips over a defective trunk. 10 (1 second)
PBX/Centrex FlashUse this timer to set the Flash interval. When a user 
flashes a trunk, the system opens the trunk circuit for 
this interval. For accurate flash function, be sure to set 
this interval for compatibility with the connected 
telco or PBX/Centrex.
If you set this interval too short, the telco may not 
always register the flash. If too long, inadvertent dis-
connects may occur.800 mS
Flash DisconnectTBD 2496mS 
						

							System Timers, Trunks
DS2000 Software ManualChapter 1: Features301
Force Idle (Trunk Guard 
Time)Use this timer to set the guard time for trunks. When 
the system disconnects a trunk (e.g., after a user hang 
up), the system keeps the line idle until this timer 
expires. The Trunk Guard Time helps prevent call col-
lisions.
If you set this interval too short, call collisions may 
occur. If too long, there will be unnecessary delays 
before you can use the trunk for a new call.25 (2.5 sec)
PBX PauseUse this timer to set the delay that occurs after the 
system dials a PBX access code. After the system 
dials the code, it waits this interval before outdialing 
the rest of the number.
If you set this interval too short, the PBX may not 
have enough time to set up the call and return dial 
tone. If too long, the PBX may disconnect the call.0
Minimum Ring Detection 
TimerUse this timer to set the threshold for ring detection. 
If the ring signal is longer than this interval, the sys-
tem interprets the signal as valid ringing. If the signal 
is equal to or shorter than this interval, the system 
ignores the ringing.
Be sure the value you enter is compatible with the 
local telco. If you set this value too short, the system 
may detect line spikes and anomalies as ringing. If 
too long, the system may not properly interpret a 
valid ringing signal.104 mS
DP Make TimerUse this timer to set the duration of the Dial Pulse 
Make signal (i.e., relay closed). This is the “on” time 
in a Dial Pulse digit. Set this timer for compatibility 
with the connected telco or PBX/Centrex. Keep in 
mind that there are three components of a Dial Pulse 
digit: Make interval, Break interval and Interdigit 
interval. An improper setting may cause misdialing.40 mS
DP Break TimerUse this timer to set the duration of the Dial Pulse 
Break signal (i.e., relay open). This is the “off” time 
in a Dial Pulse digit. Set this timer for compatability 
with the connected telco or PBX/Centrex. Keep in 
mind that there are three components of a Dial Pulse 
digit: Make interval, Break interval and Interdigit 
interval. An improper setting may cause misdialing.60 mS
DP Interdigit TimerUse this timer to set the duration of the Dial Pulse 
Interdigit signal (i.e., relay open time between each 
digit). Set this timer for compatability with the con-
nected telco or PBX/Centrex. Keep in mind that there 
are three components of a Dial Pulse digit: Make 
interval, Break interval and Interdigit interval. An 
improper setting may cause misdialing.800 mS Table 14: Program 0402 - Trunk Timers (Page 2 of 5)

Manual DTMF Tone OnThis timer sets the duration of DTMF digits for trunk 
calls manually dialed by an extension user. This is 
required because the system buffers the digits the user 
dials.
Set this timer for compatibility with the connected 
telco or PBX/Centrex. If you set this interval too 
short, the telco or PBX/Centrex may not be able to 
properly detect the DTMF digit. If too long, outbound 
dialing is unnecessarily slowed down.250 mS
Manual DTMF Tone OffThis timer sets the duration of the interval between 
DTMF digits for trunk calls manually dialed by an 
extension user. This is required because the system 
buffers the digits the user dials.
Set this timer for compatibility with the connected 
telco or PBX/Centrex. If you set this interval too 
short, the telco or PBX/Centrex may not be able to set 
up to receive the next DTMF digit. If too long, out-
bound dialing is unnecessarily slowed down.100 mS
Speed Dial DTMF Tone 
OnThis timer sets the duration of DTMF digits for Speed 
Dial trunk calls automatically dialed by the system.
Set this timer for compatibility with the connected 
telco or PBX/Centrex. If you set this interval too 
short, the telco or PBX/Centrex may not be able to 
properly detect the DTMF digit. If too long, outbound 
dialing is unnecessarily slowed down.100 mS
Speed Dial DTMF Tone 
OffThis timer sets the duration the quiet time between 
DTMF digits for Speed Dial trunk calls automatically 
dialed by the system. 
Set this timer for compatibility with the connected 
telco or PBX/Centrex. If you set this interval too 
short, the telco or PBX/Centrex may not be able to set 
up to receive the next DTMF digit. If too long, out-
bound dialing is unnecessarily slowed down.100 mS
Loop Current Detection 
TimeFor loop start trunks, loop current must be present for 
this interval before the system seizes the trunk.
Set this interval for compatibility with the connected 
telco or PBX/Centrex. If you set this interval too 
short, the system may inadvertently seize unstable 
trunks. If too long, the system may not properly seize 
a valid trunk.800 mS
Codec Digitizing MethodUse this option to set the system’s codec companding 
method type for the trunk. Be sure this option is 
always set to 0 (
µ-law companding enabled). Do not 
set this option to 1 (A-law companding enabled).0 (µ-law) Table 14: Program 0402 - Trunk Timers (Page 3 of 5)
