Configuring CBX or GX Logical Ports
Action/Description
The equipment to which you connect this port must support
the protocol you select. Lucent logical ports support the
following protocols:
UNI 4.0
UNI 3.1
UNI 3.0
IISP 3.1
IISP 3.0
ITU UNI
BICI 1.1 (NNI only)
PNNI 1.0 (NNI only)
The default Signaling Tuning parameters are based on the
ATM Protocol you select. If you change the Signaling
Tuning parameters for this port and later change the UNI
version, the default Signaling Tuning parameters for the
ATM Protocol you selected will overwrite these changes.
For more information on Signaling Tuning parameters, see
"Signaling Attributes for SVCs" on page
Select Public if at least one end of this connection attaches
to a public network. Select Private if this connection
resides completely within a private network.
This field controls the number of VPI bits in the ATM cell
header for VPCs on the CBX 3500/CBX 500 and VCCs
and VPCs on the GX 550.
Select UNI to use a range of zero (0) through 8. Select NNI
to use valid bits in a VPI range of zero (0) through 12. See
page 2-13 for more information.
When enabled (default), the port rejects a circuit creation
request if there is not enough available bandwidth. When
disabled, the port attempts to create a circuit even if there is
not enough available bandwidth (for VBR-nrt queue only).
Notes: If you disable Call Admission Control (CAC) for a
logical port, you are effectively disabling Lucent's CAC
function on that logical port. For more information about
the CAC function, see Appendix
this attribute does not admin down the logical port.
