5.4.2.2 Analog Options
This tab covers analog line specific settings. The system wide setting CLI Type (System | Telephony | Tones &
Music ) is used for to set the incoming CLI detection method for all analogue trunks.
Usability
· Mergeable: These settings are not mergeable. Changes to these settings will require a reboot of the system.
Configuration Settings
· Channel:
Set by the system. Shown for information only.
· Trunk Type: Default = Loop Start
Sets the analog line type (Ground Start, Loop Start, Loop Start ICLID).
· Ground Start
Ground Start is only supported on trunks provided by the Analog Trunk 16 expansion module. It requires that the
module and the control unit are grounded. Refer to the Avaya Branch Gateway installation manual.
· Delay Waiting for Caller ID Information.
As the system can use ICLID to route incoming calls, on analog Loop Start ICLID trunks there is a few seconds delay
while ICLID is received before the call routing can be determined.
· Signaling Type: Default = DTMF Dialing
Sets the signaling method used on the line (DTMF Dialing or Pulse Dialing).
· Direction: Default = Both Directions
Sets the allowed direction of operation of the line (Incoming, Outgoing or Both Directions).
· Flash Pulse Width: Default = 500ms. Range = 0 to 2550ms.
Set the time interval for the flash pulse width.
· Await Dial Tone: Default = 3000ms. Range = 0 to 25500ms.
Sets how long the system should wait before dialing out.
· Echo Cancellation: Default = 16ms.
Allows settings of Off, 8, 16, 32, 64 and 128 milliseconds. The echo cancellation should only be adjusted as high as
required to remove echo problems. Setting it to a higher value than necessary can cause other distortions. Not used
with external expansion module trunks.
· Echo Reduction: Default = On. (ATM4Uv2 card only)
Used when impedance matching is not required but echo reduction is. Options are On or Off.
· Mains Hum Filter: Default = Off.
If mains hum interference on the lines is detected or suspected, this settings can be used to attempt to remove that
interference. Useable with ATM16 trunks and IP500 ATM4U trunks. Options are Off, 50Hz or 60Hz.
· Impedance
Set the impedance used for the line. This field is only available for certain system locales. The value used for Default
is set by the system Locale.
· Brazil: Default = 900R
Adjustable between 600R and 900R as required by the line provider.
· Korea: Default = Default (600ohms).
In addition to the default impedance settings, an alternate set of impedance values can be selected.
· United States: Default = Default (600 ohms).
In addition to the default impedance setting, the following alternate sets of impedance values Alternate1,
Alternate2 and Alternate3 can be selected.
· The following values used for Automatic Impedance Matching: 600+2150nF, 600, 900+2150nF, 900, 220+820||
115nF, 370+620||310nF, 270+750||150nF, 320+1050||230nF, 350+1000||210nF, 800+100||210nF.
· Quiet Line:
This field is only available for certain system locales (see above). The setting may be required to compensate for signal
loss on long lines.
· Digits to break dial tone: Default = 2. Range = Up to 3 digits.
During automatic impedance testing (see below), once the system has seized a line, it dials this digit or digits to the
line. In some cases it may be necessary to use a different digit or digits. For example, if analog trunk go via another
PBX system or Centrex, it will be necessary to use the external trunk dialing prefix of the remote system plus another
digit, for example 92.
