SINGLE T1/E1/J1 FRAMER/LIU COMBO - E1 REGISTER DESCRIPTION

REV. 1.0.0

NOTE: The default value for register address 0x0340 = 0x01, 0x0341-0x034F = 0xD0, 0x0350 = 0xB3, 0x0351-0x035F =

0xD0

TxSIGSRC[1]

R/W

See Note 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.

TXSIGSRC[1:0]

SIGNALING SOURCE SELECTED

Signaling data is inserted from input PCM

data (TxSERn pin)

Signaling data is inserted from this register

(TSCRs).

Signaling data is inserted from the transmit

Overhead input pin (TxOH_n) if XRT86VL30

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)

If the Transmit Signaling Interface bit is

enabled (i.e. TxFr2048 bit = 1 in the Trans-

mit Interface Control Register (TICR) Regis-

ter 0x0120), signaling data will be inserted

from the Transmit Signaling input pin

(TxSIG_n)

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.
