FXS+ Quad Voice Option Module User Manual

Dialtone
DIALTONE

is used to enable or disable the on-board

dial-tone generation when the FXS+ is operating in the
tandem mode. When the on-board dial-tone generation
is enabled, the dial-tone will turn off after a five second
time-out.
Choices: Enabled, Disabled

Loop Rev Bat (Loop Reverse Battery)

In

TANDEM_LS

mode, this option reverses Tip and Ring

polarity when

OFFHOOK

is received from the far-end.

The Loop Reverse Battery responds to Winks and Off-
hook signals. Use

ANSWER S’VSN

to respond only to

the far-end going

OFFHOOK

. Loop Reverse Battery is

used to emulate DPO functionality.
Choices: Enabled, Disabled

Ringback

This option generates ringback tone towards the T-Span
when enabled and the FXS+ card is in one of the tandem
modes. This may be needed in cases where the network
does not provide ringback tone.
Choices: Enabled, Disabled

Dnis Delay

The option allows the FXS+ to be used in applications
such as automatic voice mail or paging systems with
telephone interfaces for POTS lines. The DNIS Delay
option allows routing information to be supplied to these
systems from the Central Office (CO).

The FXS+ is placed in

TANDEM_LS

or

TANDEM_GS

mode as required by the Customer Premises Equipment
(CPE). Supervision must be set to

WINK

mode. Signal-

ling conversion between the DID protocol expected by
the CO and POTS signalling on the 2-wire interface is
made by the FXS+.

After the CO seizes the trunk, the FXS+ waits for the CPE
to go off-hook and then sends a wink. After the wink, the
FXS+ waits for the amount of time set by DNIS delay,
then sends answer supervision toward the CO.
