DESCRIPTION-OPERATION

TxSa8ENB

R/W

Transmit Sa8 Enable

This bit specifies if the Sa8 bits (bit 7 within timeslot 0 of non-FAS frames) will be

involved in the transmission of Data Link Information.

0 = Sa8 will NOT be used to transport Data Link Information. Sa8 bits will be set to

“1” within the outbound E1 data-stream if the Sa8 bits are inserted from the trans-

mit serial input.

1 = Sa8 WILL be used to transport Data Link Information.

NOTE: Sa8 bits can be inserted from either the transmit serial input or register

depending on the Transmit SA Select Register (Register Address:

0x0130) setting. The data link interface uses Sa8 bits for transmission

only if Data Link source is from HDLC controller (DLSRC = b01 from

(TxSa8SEL = 0 from Register 0x0130).

TxSa7ENB

R/W

Transmit Sa7 Enable

This bit specifies if the Sa7 bits (bit 6 within timeslot 0 of non-FAS frames) will be

involved in the transmission of Data Link Information.

0 = Sa7 will NOT be used to transport Data Link Information. Sa7 bits will be set to

“1” within the outbound E1 data-stream if the Sa7 bits are inserted from the trans-

mit serial input.

1 = Sa7 WILL be used to transport Data Link Information.

NOTE: Sa7 bits can be inserted from either the transmit serial input or register

depending on the Transmit SA Select Register (Register Address:

0x0130) setting. The data link interface uses Sa8 bits for transmission

only if Data Link source is from HDLC controller (DLSRC = b01 from

(TxSa7SEL = 0 from Register 0x0130).

TxSa6ENB

R/W

Transmit Sa6 Enable

This bit specifies if the Sa6 bits (bit 5 within timeslot 0 of non-FAS frames) will be

involved in the transmission of Data Link Information.

0 = Sa6 will NOT be used to transport Data Link Information. Sa6 bits will be set to

“1” within the outbound E1 data-stream if the Sa6 bits are inserted from the trans-

mit serial input.

1 = Sa6 WILL be used to transport Data Link Information.

NOTE: Sa6 bits can be inserted from either the transmit serial input or register

depending on the Transmit SA Select Register (Register Address:

0x0130) setting. The data link interface uses Sa6 bits for transmission

only if Data Link source is from HDLC controller (DLSRC = b01 from

(TxSa6SEL = 0 from Register 0x0130).

TxSa5ENB

R/W

Transmit Sa5 Enable

This bit specifies if the Sa5 bits (bit 4 within timeslot 0 of non-FAS frames) will be

involved in the transmission of Data Link Information.

0 = Sa5 will NOT be used to transport Data Link Information. Sa5 bits will be set to

“1” within the outbound E1 data-stream if the Sa5 bits are inserted from the trans-

mit serial input.

1 = Sa5 WILL be used to transport Data Link Information.

Sa5 bits can be inserted from either the transmit serial input or register depending

on the Transmit SA Select Register (Register Address: 0x0130) setting. The data

link interface uses Sa5 bits for transmission only if Data Link source is from HDLC

controller (DLSRC = b01 from Register 0x0109) and if Sa5 bits are inserted from

the transmit serial input (TxSa5SEL = 0 from Register 0x0130).
