16-CHANNEL E1 SHORT-HAUL LINE INTERFACE UNIT
D5
ATAOS_n
Automatic Transmit All Ones
If ATAOS_n is selected, an all ones pattern will be transmitted from
TTIP/TRING if the channel experiences an RLOS condition. If
RLOS does not occur, ATAOS_n will remain inactive.
"0" = Disabled
"1" = Enabled
R/W
0
D4
TAOS_n
Transmit All Ones
If TAOS_n is selected, an all ones pattern will be transmitted from
TTIP/TRING if the transmitter is turned on. Remote Loop Back
has priority over TAOS.
"0" = Disabled
"1" = Enabled
R/W
0
D3
RLAM_n
RLOS/AIS Mode Select for channel n
This bit is used to select the industry standard for declaring / clear-
ing RLOS and AIS functionality. See the Receive section of the
Line Interface description.
"0" = ITU G.775
"1" =ETSI300233
R/W
0
D2
TXOE_n
Transmit Output Enable
Upon power up, the tranmitters are tri-stated. This bit is used to
enable the transmitter for this channel if the TxOE pin is pulled
"High". If the TxOE pin is pulled "Low", all 8 transmitters are tri-
stated.
"0" = Transmitter is disabled
"1" = Transmitter is enabled if TxOE pin is pulled "High"
R/W
0
D1
RCLKinv_n
Receiver Clock Invert
This bit is used to invert receive clock update edge with respect to
RPOS/RNEG output data.
"0" =RPOS/RNEG data is updated on the rising edge of RCLK
"1" =RPOS/RNEG data is updated on the falling edge of RCLK.
R/W
0
D0
TCLKinv_n
Transmit Clock Invert
This bit is used to invert transmit clock sampling edge with respect
to TPOS/TNEG input data.
"0" =TPOS/TNEG data is sampled on the falling edge of TCLK
"1" =TPOS/TNEG data is sampled on the rising edge of TCLK.
R/W
0
