Specifying the Physical Line Length
Line Buildout conditions the signals to mitigate attenuation, and depends on the
physical length of the T1 line. You can configure a line length to a value from 1
through 655 ft. By default, the T1 Line Buildout is based on a physical line length
of 1 foot.
You can configure the approximate length of the cable connecting the BayStream
platform and the associated T1 equipment for this interface.
Setting the Internal Clock Mode
The T1 equipment associated with a T1 interface must use a compatible transmit
clock. The T1 interface supports three sources for the transmit clock:
• Internal -- Indicates that the BayStream software sets the clock.
• Slave -- Indicates that the incoming data stream sets the clock
• Manual -- Indicates that jumpers on the T1 link or net module set the clock.
You can set the Clock Mode on this interface.
By default, the T1 interface uses manual clock mode, determined by hardware
configuration jumpers. Refer to Installing T1 Link Modules in BN Platforms for
information on configuring the T1 module’s hardware jumpers.
