You can use the Home and Config keys to cycle through the
applications. The menus cycle in order, top to bottom as
shown on the main application screen.
For example, if you are in the Modem Emulate application,
pressing Home will move to the Data application, and then the
VoIP application, and then IP Video.
The same methodology applies to the configuration menus. If
you are viewing the General modem settings, pressing Config
will move to the Data settings, and then VoIP General
settings, and then the Video Settings.
The sealing current terminator, HST3000-SC, is an optional
accessory available for DSL service. It is used when sealing
current or wetting current must be terminated. Typically this
occurs in an all-digital environment, but is not typical in DSL
since the equipment (NT1 or telephone) provides termination.
The LED on the module indicates presence of sealing current.
Place the module in-line, using the provided test cable.
The module is designed to terminate voltages under 80 volts,
anything over 80V may make the module act erratic (LED
flicker, go dim, etc.)
NOTE:
It is not recommended leaving the sealing current termina-
tor on the line in the presence of a repeater because the
module oscillates and could cause signal integrity issues
effecting HST test results.
CAUTION: DAMAGE TO MODULE
Placing the sealing current terminator on a line with voltage
over 150 volts may damage the unit.
