TABLE 55: RECEIVE SIGNALING CONTROL REGISTER 0-23 (RSCR 0-23)
HEX ADDRESS: 0Xn3A0 TO 0XN3B7
BIT
FUNCTION
TYPE
DEFAULT
DESCRIPTION-OPERATION
6
SIGC_ENB
R/W
0
Signaling substitution enable
This bit enables or disables signaling substitution on the receive
side on a per channel basis. Once signaling substitution is enabled,
received signaling bits ABCD will be substituted with the ABCD val-
ues in the Receive Substitution Signaling Register (RSSR).
Signaling substitution only occurs in the output PCM data
(RxSERn). Receive Signaling Array Register (RSAR - Address
0xn500-0xn51F) and the external Signaling bus (RxSIG_n) output
pin will not be affected.
0 = Disables signaling substitution on the receive side.
1 = Enables signaling substitution on the receive side.
5
OH_ENB
R/W
0
Signaling OH interface output enable
This bit enables or disables signaling information to output via the
Receive Overhead pin (RxOH_n) on a per channel basis. The sig-
naling information in the receive signaling array registers (RSAR -
Address 0xn500-0xn51F) is output to the receive overhead output
pin (RxOH_n) if this bit is enabled.
0 = Disables signaling information to output via RxOH_n.
1 = Enables signaling information to output via RxOH_n.
4
DEB_ENB
R/W
0
Per-channel debounce enable
This bit enables or disables the signaling debounce feature on a per
channel basis.
When this feature is enabled, the per-channel signaling state must
be in the same state for 2 superframes before the Receive Framer
updates signaling information on the Receive Signaling Array Regis-
ter (RSAR) and the Signaling Pin (RxSIGn). If the signaling bits for
two consecutive superframes are not the same, the current state of
RSAR and RxSIG will not change.
When this feature is disabled, RSAR and RxSIG will be updated as
soon as the receive signaling bits have changed.
0 = Disables the Signaling Debounce feature.
1 = Enables the Signaling Debounce feature.
