these strings do not carry timing information.

Controls the link transmit signal characteristics.
Options depend on whether the link should be configured with
CSU.
When the link is configured without CSU, the transit signal mask
is selected according to the transit line length (0-655 ft.), to meet
DSX-1 requirements.
When the link is configured with CSU, the transit signal is
attenuated by 7.5, 15, or 22.5 dB.
