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 14: Program 0404 - Analog Station Timers (Page 2 of 2)

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
