186 Matrix ETERNITY NE System Manual
• Ring Cadence OFF Timer: Configure this timer to set OFF time for Ring cadence. During an incoming call
on the CO port, if the CO gives ring with a long Ring OFF period, the system will consider that the ring has
been stopped, and it will stop ringing the SLT port, even though the incoming call is still present.
To get correct indication, the ETERNITY NE supports the Ring Cadence OFF timer on the CO port so that
ring can continue, even for incoming calls with long Ring OFF period.
The range of the Ring Cadence OFF timer is from 1 to 6 seconds. Default: 6 seconds.
• Flash Time (msec): This parameter is relevant for dialing out Flash on the CO Trunk to access some of
the features of the CO Network. Configure the desired time of Flash to be generated on the CO Trunk.
Default: 600 milliseconds.
• ON Hook Speed: This parameter allows you to set the duration of time for the line-side device to go on-
hook.
The ON-Hook speed you set here is measured from the time the ON-Hook bit is cleared until the loop
current equals zero. Select the desired ON-Hook Speed from the following options:
•
<0.5msec
• 3 msec
• 26 msec
Default: <0.5msec.
• OFF Hook Speed: This parameter defines the time to settle the line transients after which transmission or
reception can occur. Select the desired OFF-Hook Speed from the following options:
•
512 ms
• 128 ms
• 64 ms
• 8 ms
Default: 8 ms.
16.
To limit Loop Current, enable Current Limiting . Default: Disabled. When this flag is enabled, the Loop
Current is limited to a maximum of 60mA.
17.
Set the Minimum Loop Current at which DAA module of the CO Trunk port can operate. Select the
minimum operational loop current from the following options as per your requirement:
•
10
• 12
• 14
• 16
Default: 10 mA.
18.
If required, you may adjust the Tip Ring Voltage on the line side.
In countries where Low voltage is required, you should set lower TIP/RING voltage in ETERNITY. Adjust
the values of the Tip Ring Voltage to match your country requirements from the following options:
•
3.1
• 3.2
• 3.35
• 3.5
Default: 3.5.
