OTE
:
The default value for register address 0xn340 = 0x01, 0xn341-0xn34F = 0xD0, 0xn350 = 0xB3, 0xn351-0xn35F =
0xD0

Channel signaling control
These bits determine the source for signaling information. The table
below presents the different sources for signaling information corre-
sponding to different settings of these two bits.

00
Signaling data is inserted from input PCM
data (TxSERn pin)
01
Signaling data is inserted from this register
(TSCRs).
10
Signaling data is inserted from the transmit
Overhead input pin (TxOH_n) if XRT86VL32
is configured in the base rate configuration
and if the Transmit Signaling Interface bit is
disabled. (i.e. TxMUXEN bit = 0, TxI-
MODE[1:0] = 00, and TxFr2048 bit = 0 in the
Transmit Interface Control Register (TICR)
Register 0xn120).
If the Transmit Signaling Interface bit is
enabled (i.e. TxFr2048 bit = 1 in the Trans-
mit Interface Control Register (TICR) Regis-
ter 0xn120), signaling data will be inserted
from the Transmit Signaling input pin
(TxSIG_n)
11
No signaling data is inserted into the input
PCM data. Setting these two bits to ‘11’ will
configure the xyxx bits only, where x bits are
inserted from this register (TSCR) and y bit
reflects the alarm condition.
