GXE502X User Manual 11/2/2009
11
 Trunk Name: This is the name used to identify this set of trunk(s). For example: carrier A,
carrier B, Telco C, etc.
 Line: Please specify the FXO ports that you want to include in this profile either one by one or
as a range. For example: 1, 2-5, 8.
 Prefix: This is the prefix that the GXE will use to create the outbound call routing profile so that
it will know which trunk to grab for an outgoing call. When the user wants to make a call he will
have to use this prefix to grab this particular set of lines.
 Call Routing Profile: This section will indicate the GXE where to route the calls coming into this
PSTN trunk. You will see two boxes, one with the available list and another one with the
selected call routing profiles. It is recommended to use either the play voice menu profile which
will reproduce the auto-attendant menus according to the playing rules set, or to select the
general inbound which will route the call accordingly to what the user has selected in the
general inbound conditions and values.
Advanced settings:
Click on the Advanced link to show the advanced settings options, here you will find the PSTN
Line Parameter Settings and the PSTN Port Parameter Assignments.
PSTN Line Parameter Sets: This section lets you specify the line disconnect signaling,
impedance, as well as the caller ID standard and line dialing settings.
Set Name: This is the name that corresponds to this line or set of lines to be configured. For
example a user could have 2 sets of PSTN lines from different providers with different settings.
 Enable Current Disconnect: Default is Yes.
This value should be used when the PSTN provider or local Telco Carries uses a line power
drop to indicate call completion to the subscribing end point. In this case the FXO port of
GXE502X will search for a power drop with the preconfigured time frame to disconnect call
from a VoIP extension.
 Current Disconnect Threshold:
This is a preconfigured value of duration for a line power drop used by specific service
providers or Telco Carriers. For example, with a configured value of 500ms, the device will
ignore any random voltage drops on the line if the duration of such a drop is less than 500ms.
The call will NOT be considered as terminated, but will clear a call if a drop is equal or more
than 500ms. This is useful to prevent unnecessary call drops in some low quality PSTN lines.
However inappropriate parameters may cause calls to drop unexpectedly or cause the line not
to release as expected. Please consult with the local Telco carrier before changing this
parameter.
 Enable Tone Disconnect: Default is YES
This feature causes a Busy Tone to be used as the FXO line disconnection signal when set to
YES. It is used by some Telcos or enterprise POTS PBX.
 BT Event or Busy Tone Event: This is the number of cadence cycles to be detected in order
to disconnect the call. In other words; in the cases where the PSTN provider signals a call
termination by playing a busy tone the GXE will listen to how many times these tones are
