Specifying a cable length for a DS3 port

Chapter 5 Managing Physical Ports

You can specify the coaxial (BNC) cable length for a DS3 port. The coaxial cable length is up to these numbers in feet:

•225: 0-225 feet, 0-68 meters.

•450: 225-450 feet, 68-137 meters.

The default cable length is 225 (i.e. 0-225 feet).

Note: You must disable the physical port before you can change, clear or reset any physical port parameters. For more information about how to disable a physical port, see Disabling a Physical Port on page 49.

To configure the coaxial cable length for a DS3 port, use the pport set length command.

Command:	M4-DS3s8:/>pport set length <<slot>.<port>> [225450]
Example:	M4-DS3s8:/>pport set length 8.1 225
Parameters:	<pport id>	The physical port identifier in the form <slot>.<port number>.
	225	Sets the allowable coaxial cable length to:
		0-225 feet, 0-68 meters.
	450	Sets the allowable coaxial cable length to:
		225-450 feet, 68-137 meters.

Specifying a mapping mode for a DS3 port

You can specify for a DS3 port the mapping mode used for the transport of ATM cells over DS3. The mapping mode is either ADM or PLCP. The default mapping mode is ADM.

To set the mapping mode for a DS3 port, use the pport set mapping command.


Command:	M4-DS3s8:/>pport set		mapping	<<slot>.<port>> [adm plcp]
Example:	M4-DS3s8:/>pport set		mapping	8.2 plcp
Parameters:	<pport id>	The physical port identifier in the form <slot>.<port.number>.
	adm	Sets the mapping mode to ADM. The default setting is ADM.
	plcp	Sets the mapping mode to PLCP.
