Mediant 600 & Mediant 1000
Parameter Description

FXS Port 1 of each FXS module
FXS Port 1 connects to the POTS (Lifeline) phone as well as to the
PSTN / PBX, using a splitter cable.
 [0] = Lifeline is activated upon power outage (default).
 [1] = Lifeline is activated upon power outage or when the link is
down (physically disconnected).
 [2] = Lifeline is activated upon a power outage, when the link is
down (physically disconected), or upon network failure (logical
link disconnected).
Notes:
 For this parameter to take effect, a device reset is required.
 This parameter is applicable only to FXS interfaces.
 To enable Lifeline upon a network failure, the LAN watch dog
must be activated (i.e., set the parameter EnableLANWatchDog
to 1).
 A Lifeline phone connection can be setup for each FXS module
(using Port I) housed in the chassis.
 For information on Lifeline cabling, refer to the Installation
Manual.
Web: Delay After Reset [sec]
[GWAppDelayTime]
Defines the time interval (in seconds) that the device's operation is
delayed after a reset.
The valid range is 0 to 45. The default value is 7 seconds.
Note:
This feature helps overcome connection problems caused by
some LAN routers or IP configuration parameters' modifications by
a DHCP server.
[Mediant1000DualPowerSuppl
ySupported]
Determines whether the device sends raised alarms (to the SNMP
client and/or Web interface) concerned with the Power Supply
modules.
 [1] (default) = No alarms are sent.
 [2] = The device sends alarms if one of the Power Supply
modules is removed from the chassis. These alarms are
reflected in the SNMP and Web interface.
Notes:
 For this parameter to take effect, a device reset is required.
 If this parameter is set to 2 and for this feature to be functional,
both Main and Redundant Power Supply modules must be
present in the chassis.
[GroundKeyDetection]
Enables analog ground-key detection for the device. The device's
FXS and FXO modules implement ground-start signaling. When
disabled, the device uses loop-start signaling.
 [0] = Disable (default)
 [1] = Enable (enables ground start)
Notes:
 For this parameter to take effect, a device reset is required.
 For ground-start signaling, ensure that the FXO G module is
installed (and not the regular FXO module) in the device's
chassis.
 For FXO ground-start signaling, ensure that the parameter
EnableCurrentDisconnect is set to 1 and the parameter
FXOBetweenRingTime is set to 300.

FXS ground-start interface does not generate a ringing voltage.
