Field (Bits)
Description
HS_TX_COND
(15)
Send cells with all 1s when in high-speed mode (line 0 only).
HS_RX_COND
(14)
Fetch receive conditioning data from the R_COND_DATA buffer for line 0, channels 0
and 1. High-speed mode (line 0 only).
T1_MODE
(13)
Determines mode of the line. This bit is valid only if the MIXED_MODE_EN bit in the
COMP_LIN_REG is set.
1
0
Line is in T1 mode.
Line is in E1 mode.
E1_WITH_T1_SIG
(12)
Enables T1 signaling while in E1 mode for this line. Signaling is updated every
24 frames instead of every 16 frames. This bit is valid only when the line is in E1
SDF-MF mode. AAL1 cell structures contain a signaling nibble every 25 bytes instead
of every 17 bytes per single DS0.
1
0
Use T1 signaling.
Use E1 signaling.
Not used
(11:6)
Write with a 0 to maintain future software compatibility.
CLK_SOURCE
(5:4)
Selects TL_CLK source. This value will override the setting defined by the TLCLK_
OUTPUT_EN input. If switching from an external to an internal clock or visa versa,
make sure there are not two clocks driving simultaneously.
00 Use external clock. (TL_CLK is an input).
01 LOOPED - Use RL_CLK as the clock source.
10 NOMINAL - Generate a clock of the nominal (T1 or E1) frequency from
SYS_CLK.
11 SRTS - Generate a clock frequency based on the received SRTS values.
Not used
(3)
Write with a 0 to maintain future software compatibility.
