Signaling Configuration Table

up_arrow128b.gif (883 bytes)
This group is mandatory.

Each entry describes one UNI/NNI. Note that the table is indexed by 'atm' interfaces, rather than by 'aal5' entities.

Field Descriptions

decAtmSignallingIndex An arbitrary integer index that can be used to distinguish among multiple signaling entities for the same (physical) interface.
decAtmSignallingMode Indicates the mode in which the port is configured to run.

Q2931 Timer Table

up_arrow128b.gif (883 bytes)
This table is optional. It lets network managers examine and configure the Q.2931 timeouts documented in the ATM Forum's UNI 3.0 Specification.

Field Descriptions
