Answer Supervision Configures answer supervision for the appropriate voice port. Answer
supervision (when the far end answers the call) is indicated by using reverse
battery polarity. This is valid for an outbound call only. On an FXS interface
type we respond to LSAS (Line Side Answer Supervision) signaling on the T1.
Our response is to reverse battery polarity on (T-R). Telco must configure their
T1 for LSAS if this is not a point-to-point T1.
E&M Conversion Configures the selected voice port for E&M signaling conversion. By enabling
this option, other selections become available that are E&M trunk specific. This
option is sometimes referred to as TANDEM conversion. The following
submenu items become visible when
E&M CONVERSION is ENABLED:
Submenu Description
E&M Supervision
Configures the E&M trunk as either Immediate start or Wink start. This
configuration is for the Rx and Tx direction. When DNIS delay is set, this
option only configures the Rx direction.
Dial Tone
Configures the ATLAS 830 to generate Dial Tone out the selected FXS port in
response to the 2W going off hook (outgoing call). Generally, dial tone is
provided by the Class 5 switch delivering the T1, but in some instances, the
switch cannot provide dial tone.
Ringback
Configures the ATLAS 830 to generate ringback tone to the far end while the
selected FXS port is ringing. Generally, ringback is provided by the Class 5
switch delivering the T1, but in some instances, the switch cannot provide
ringback tones.
DNIS
DelayDefines the time we delay after transmitting a wink in response to the 2W
going off hook (after ringing) before we send off hook in the RBS signaling.
This field is only valid for E&M conversion. The timing is as follows:
DNIS Wink Timeout
When DNIS DELAY is ENABLED, a wink will be returned to the originating switch
after 5 seconds if the FXS does not detect an off hook. This option, when
DISABLED, allows the FXS port to ring without winking until the call is
answered.
Trunks can be taken out of service by telco if there is No wink. Use caution when
disabling this option.
