Preliminary Information
MT8910-1
9-15
Table 3. Control Register 2
1
The ST-BUS incoming data is still output on the line if the MT8910-1 is activated. Supported in both SINGLE and DUAL port modes.
2
The incoming data from the line is still output on to the ST-BUS. The other incoming channels on the ST-BUS are still output on to
the line if the device is activated. Supported in both SINGLE and DUAL port modes.
3
Signal is internally looped back and is still output to the line and overrides the internal activation state machine.
4
One pulse is transmitted every 1.5 ms.
5
The Insertion Loss Measurement Test Signal is a scrambled (all one’s data), framed 2B1Q signal.

ADCGAIN
Selects between two gain values in the delta-sigma A/D converter. When high, selects a 3 dB
higher gain.
2
MSWAP
Mode Swap. In the LT mode, MSWAP=1 will result in the DSLIC using the NT’s scrambling/
descrambling polynomials and activation sequence. This allows two DSLICs on the same LT line
card to exchange static data in the B- and D- channels.
MSWAP can also be used in the NT mode.
