DESCRIPTION-OPERATION

A (x)

R/W

See Note

Transmit Signaling bit A

This bit allows user to provide signaling Bit A (Octets 0-23) if

Robbed-bit signaling is enabled (Rob_Enb bit of this register set to

1) and if signalling data is inserted from TSCR (TxSIGSRC[1:0] =

01 in this register).

NOTE: Register 0xn340 represents signaling data for Time Slot 0,

and 0xn357 represents signaling data for Time Slot 23.

B (y)

R/W

See Note

Transmit Signaling bit B

This bit allows user to provide signaling Bit B (Octets 0-23) if

Robbed-bit signaling is enabled (Rob_Enb bit of this register set to

1) and if signalling data is inserted from TSCR (TxSIGSRC[1:0] =

01 in this register).

NOTE: Register 0xn340 represents signaling data for Time Slot 0,

and 0xn357 represents signaling data for Time Slot 23.

C (x)

R/W

See Note

Transmit Signaling bit C

This bit allows user to provide signaling Bit C (Octets 0-23) if

Robbed-bit signaling is enabled (Rob_Enb bit of this register set to

1) and if signalling data is inserted from TSCR (TxSIGSRC[1:0] =

01 in this register).

NOTE: Register 0xn340 represents signaling data for Time Slot 0,

and 0xn357 represents signaling data for Time Slot 23.

D (x)

R/W

See Note

Transmit Signaling bit D

This bit allows user to provide signaling Bit D (Octets 0-23) if

Robbed-bit signaling is enabled (Rob_Enb bit of this register set to

1) and if signalling data is inserted from TSCR (TxSIGSRC[1:0] =

01 in this register).

NOTE: Register 0xn340 represents signaling data for Time Slot 0,

and 0xn357 represents signaling data for Time Slot 23.

See Note

Robbed-bit signaling enable

This bit enables or disables Robbed-bit signaling transmission. If

robbed-bit signaling is enabled, signaling data is conveyed in the

8th position of each signaling channel by replacing the original LSB

of the voice channel with signaling data.

0 = Disables Robbed-bit signaling.

1 = Enables Robbed-bit signaling.
