Mitel Fax Memo Manual

							# 152 In-ring minimum power 
The line card port uses these parameters for incoming ringing detection. 
l Incoming ringing bursts must be at least as long as the in-ring on-time low 
value, and less than the In ring on time high value. 
l There must be an interval between ringing bursts that is at least as long as the 
in-ring off-time value. 
l Incoming ringing power must be above the in-ring maximum power threshold 
to be detected. 
l When incoming ringing power falls below the in-ring minimum threshold, 
ringing detection is cleared. 
r. 
Output Signaline Adiustments; 
# 14 Pulse per second 
This line exception defines the pulse per second rate for dial pulses VoiceMemo 
outdials. 
#23 Flashhook time 
This is the number of hundredths of a second that VoiceMemo remains onhook 
during flash while transferring a call. 
#24 Wink start 
Wink start is a type of out-signaling capability that usually is required by the central 
office for DID applications. Certain PBXs also may require wink start signaling on 
E&M tie trunk connections. The default for this parameter is disabled. 
#154 Pulse out interdigit delay 
This is the amount of time a port waits between accepting a pulse output command 
and starting the pulse output of digits. 
I 
#164 DTMF output duration 
This is the length, in hundredths of a second, of each DTMF tone VoiceMemo 
outdials. 
#166 DTMF interdigit delay 
This is the amount of silence, in hundredths of a second, between each DTMF tone 
VoiceMemo outdials. 
# 176 DTMF output level 
This sets the amplitude of DTMF tone output. 
Page 79  
						

							DTMF Detection: 
#6 DTMF detect enabled/disabled 
This parameter is used to selectively disable or enable DTMF detection on line card 
ports. DTMF detection normally is enabled; it may be disabled to prevent callers 
OHP 
certain ports from logging into mailboxes, for example. 
#25 Enable DTMF Co1 3 
This line exception enables fourth column DTMF tones (A, B, C, D). Default is 
disabled. 
#32 DTMF receive debounce time 
The DTMF receive debounce time specifies the amount of time apTMF key must be 
depressed before it is recognized as a valid VoiceMemo command. This line 
exception is active except when playing or recording a message. 
#33 Record DTMF receive debounce 
The Record DTMF receive debounce time stipulates how long a DTMF key must be 
depressed during the recording of a message for the system to recognize the tone as 
DTMF. The value of this line exception is set higher than line exception 32, which 
means the DTMF key must be pressed slightly longer during the recording of 
messages than at other times. Since higher voices often have components that can be 
mistaken for DTMF tones, but these components are usually of short duration, this 
parameter can prevent false DTMF detection. 
#34 Play DTMF receive debounce 
This parameter determines how long a DTMF key must be depressed during the 
playing of a message for the system to recognize tone as DTMF input. Like the 
Record DTMF receive debounce time, the value of this line exception is set higher 
than line exception 32. This prevents VoiceMemo from mistaking high voice 
frequencies for DTMF when messages are played. 
Greet Command Parameters: 
#8 Dead line timeout 
Dead line timeout sets the number of seconds VoiceMemo waits for ringing, busy 
tone, or speech after issuing a greeting. Silence intervals greater than the dead line 
timeout value are interpreted as a dead line or disconnect. 
Page 
80  
						

							#128 Minimum busy half cycle (greet) 
When the greet command is active, the line card uses the minimum busy half cycle 
(greet), together with line exceptions 174 (minimum busy detection time) and #175 
(maximum busy detection time) to determine if a signal it is receiving is a busy tone. 
This parameter also is used with parameters 172 (minimum reorder detection time) 
and 173 (maximum reorder detection time) to detect reorder tone while the greet 
command is active. 
#lO Silence timeout 
#ll Speak timeout 
#146 Speech detect minimum time 
#170 Speech detect minimum power (greet) 9 
The line card uses these parameters, together with a characteristic called absolute 
steadiness, to detect speech. 
l The speech or energy burst received by the line card must have a duration that 
falls between the values set by parameters #146 and #l 1, and have at least as 
much energy as the value of parameter #170. 
l The speech or energy burst must be followed by a minimum amount of 
silence, as specified by parameter #lo. (This is how the line card 
differentiates multiple bursts from a single long burst of energy or speech.) 
l If the signal received meets these criteria, the greet software measures the 
absolute steadiness, or the ratio of minimum energy to maximum energy of 
the signal, to differentiate between a call progress tone and speech. Gall 
progress tones have steady energy throughout the speech detect interval; 
speech has extremely variable energy. 
#182 Ringback tone maximum silence 
- 
This line exception specifies the maximum silence allowed between ringback tone 
cycles before a greet command terminates automatically with a speech detect event. 
SDeech and Silence Detection Duriw Recordinz 
#160 Silence delay 
This is the maximum amount of silence, specified in frames, needed to detect a pause. 
# 16 1 Minimum miniframes not silent 
This is the minimum number of minil?arnes used to reactivate recording after a pause 
is detected. 
Page 81  
						

							# 162 Minimum speech frames 
This is the minimum number of consecutive frames of speech (as determined by 
#163) required to set the recording timeout. The Minimum Speech Frames parameter 
prevents recording from stopping after it has started. 
# 163 Minimum miniframes speech 
This is the minimum number of miniframes of speech needed to determine that an 
entire frame contains speech. This parameter also prevents recording from stopping 
after it has started, 
PromDt and MessarJe Outmt Controls: 
r. 
#I4 
Pause compression enable 
VoiceMemo line cards normally compress intervals of silence, to eliminate pauses in 
speech before sending messages to the hard disk for storage. In addition to saving 
disk storage space, pause compression usually improves the quality of message 
playback. This feature may be disabled, if necessary. 
#13 Enable AGC 
Automatic Gain Control (AGC) adjusts weak and strong signals to keep the output 
level of speech constant. 
This means callers and system users do not hear wide 
variations in the loudness and softness of greetings, prompts, and messages played to 
them. 
#178 Record prompt output level 
This controls the amplitude of the “beep” that is issued before allowing the recording 
of a message or greeting. The record prompt also is affected by # 156 Record prompt 
duration, which controls the length of the record prompt signal, and #158 Record 
prompt frequency, which specifies the frequency, in hertz, of the record prompt beep. 
New Line ExceDtions-Sumorted bv 5.02B and 5.03B: 
~9200 Background power lower limit 
The default is 10. Background power noise levels below this limit are not recorded. 
#2 14 DTMF detect minimum power ratio 
The default is 16. Ratio of noise power just before DTMF to power during DTMF 
must be above this value before DTMF events are sent to the module while in record 
mode. This ratio adapts upward during recording if a high signal to noise ratio is 
found. The line exception value corresponds to internal power detectors, and thus is 
not directly related to dB.

							APPENDIX III: Line Card Interfkes 
The following line card interfaces are supported by the platform: 
l Loop start-The loop start interface is with 4/8-port loop start line cards. 
l Ground start-The ground start interface is provided with 4/8-port ground start line 
cards. 
l DID-The DID/E&M interface is provided with 4/8-port loop DID line cards. 
l 2-wire E&M-This interface is provided with DID/E&M line cards. Both E&M 
Types I & V are supported. 
l Tl-The platform supports direct digital connections to Tl (North America) and, the 
Tl interfaces emulate loop-start, ground start, DID, and E&M.protocols. 
l El-Direct digital El connectivity is supported on the Series 6 platform using SS7 
integration protocal. Futures will support ESDI, Rl, and R.2 protocals. 
l A power/configuration card is required when analog DID/E&M or groundstart line 
interfaces are employed. This card provides -48V to the line interface circuits 
on these 
cards. One power/configuration card serves up to four 4/8-port analog line cards.
