FXS Card
PATTRN
The Pattern field selects an outgoing test pattern for the current card port. The test pattern is
generated by the system and sent to the selected port. You can select a different pattern for
each port. The none option disables the test pattern. The D-mW (Digital milliwatt) option
sends a 1 kHz tone at 0.0 dBm. The setting of the Rx TLP setting affects the D-mW signal
level. The quiet option places a 600-ohm termination on the line so that no analog signal is
sent (idle mode).
HYBRID
The Hybrid option assigns a three byte pattern to define the adjustment for return loss (similar
to Build Out Capacitors). The default, set1, balances to the ideal termination of 600 ohms +
2.15 uF. The other settings are reserved for future use.
RINGBK
The ringback setting specifies whether a ringback tone is generated by the system and sent
towards the network. Turn this option off when the network service does not provide an
audible ringing tone to the calling party.
SIG CONV
The Signaling Conversion parameter allows you to change the transmit ABCD signaling bits
from CCITT (E1) to ANSI (T1) standards. This conversion is completed regardless of the type
of WAN card (CSU/DSX or CEPT) to which the FXS card is attached.
The options are off if ANSI signaling is used and on to convert transmit signaling from ANSI
to CCITT format according to the Interface Card Conversion Table for FXS signaling. This
setting also converts receive signaling from CCITT to ANSI.
