DSX-1 Config A-1: T-1 Timing Mode
Indicates the mode of the transmit clock for the NB30 equipped with a
DSX-1 module. The T1 Timing Mode is set by switching the Config A-1
switch on the back panel of the NB30. (See the NB30 Ethernet Bridge
User's Manual for more information.)
OFF places the unit in a mode where the transmit clock is generated from
an internal clock.
ON places the unit in a mode where the transmit clock is generated from
the T1 link.
Config A-2: STA enabled
Indicates whether the Spanning Tree Algorithm (STA) is disabled or
enabled. The Spanning Tree Algorithm is set by switching the Spanning
Tree Algorithm Switch on the back panel of the NB30. (See the NB30
Ethernet Bridge User's Manual for more information.)
OFF means that the Spanning Tree Algorithm is disabled.
ON means the Spanning Tree Algorithm is enabled.
