SYNTAX

LONGINT

ACCESS read-only
STATUS mandatory
DESCRIPTION

"Select the data rate from the list of

available choices, or enter any data

rate that is valid for the traffic

modem."

::= { controlChannelTableEntry 21 }


ctrlChanReferenceEbNo OBJECT-TYPE
SYNTAX

REAL

ACCESS read-write
STATUS mandatory
DESCRIPTION

"This is the stored value at which the

received Outbound Control Channel Eb/No

will be maintained under clear sky conditions,

as measured at the LinkSync modem."

ctrlChanUplinkPowerControl OBJECT-TYPE
SYNTAX

BOOLEAN

ACCESS read-write
STATUS mandatory
DESCRIPTION

"This allows the operator to enable/disable

the Uplink Power Control option.

Uplink Power Control (UPC), a standard

feature of the MIDAS system, is the method

used to establish a network-wide reference

for power. Specifically, UPC is used to

ensure that the Outbound Control Channel

carrier is downlinked from the satellite at

a constant power level. This reference

allows each of the nodes in the network

to determine and report (via regular

polling from the NMS) if, and to what

degree, downlink degradation of a node

(and its associated traffic channels)

may be occurring due to fade, whether

from rain or other non-atmospheric

conditions."

::= { controlChannelTableEntry 23 }


ctrlChanAcquisitionRange OBJECT-TYPE
SYNTAX

LONGINT

ACCESS read-write
STATUS mandatory
DESCRIPTION

"Maximum frequency adjustment allowed

of the nodes during node acquisition.

This is the Inbound Acquisition Range in kHz

(Range: 0 to 35).

The Acquisition Range is a value (in kilohertz)

that is used to provide additional guard band

for the bursting Inbound Control Channel. This
