configurable. So, for example, some channels of a TalkAnytime might use the FXO interface and others
the FXS, etc.
6. If you intend to configure the TalkAnytime unit remotely using the TalkAnytime Windows GUI, connect
an RJ-11 phone cable between the Command Modem connector (at the rear of the TalkAnytime unit) and
a receptacle served by a telco POTS line. See Figure 3-6.
The Command Modem is built into the TalkAnytime unit. To configure the TalkAnytime unit remotely
using its Windows GUI, you must call into the TalkAnytime's Command Modem. Once a connection is
made, the configuration process is identical to local configuration with the Windows GUI.
7. Ensure that the TalkAnytime unit is properly connected to earth ground.
This can be accomplished by connecting a grounding wire between the chassis grounding screw (see
Figure 3-7) and a connector securely connected to the ground (GND) of the building's electrical system.
Ground Connection Details. Ensure that the unit is securely and permanently connected to an earth
ground (GND) with a ground wire of 18 gauge (18 AWG) or thicker. The ground wire needs to be
installed between the grounding screw on the TalkAnytime chassis and a permanent earth ground.
Whether the TalkAnytime unit is used in a rack or on a desktop, you must verify that the earth ground
connection is permanent and reliable. In order for the ground connection to be considered permanent,
the grounding wire must connect to the earth ground of the building's electrical wiring system and the
ground connection must use a screw terminal or other reliable means of fastening. The ground
connection must not be as easily disconnected as, for example, a power cord.
