until it registers with the VMS and receives assignment into dSCPC, or until all
necessary transactions are completed. The slot is then released for use by
another Remote unit that is attempting to enter the channel.
Remotes can be set to one of four operating modes—Disable, Offline, Wait, and
Online—from the ECMv2 Mode command in the STDMA menu. In addition,
commands for setting parameters to accomodate any mismatches between the
Hub LNB and the Remote BUCs are presented: LNB LO Frequency (Hub),
BUC LO Frequency (Remote), and Satellite Conversion Frequency.
ECMv2 Mode
This menu item appears for Remote modems operating in ECMv2 only.
Each Remote can be set to a designated mode of operation in ECM:
• Disable – the ECM function for this Remote is disabled.
• Offline – the Remote will not transmit (muted).
This mode may be chosen for radio silence applications.
• Wait – the Remote will register with the controller and remain in the ECM
wait queue without assignment for switching into dSCPC mode. This
mode may be chosen by operators who wish to manually control (via
diagnostic switch) when a Remote is to be switched and utilize bandwidth
from the pool.
• Online – the Remote will register with the controller and request dSCPC
bandwidth for switching.
In order for a Remote to automatically switch into SCPC mode and pass data
traffic, the ECMv2 Mode must be set to Online.

Tip: For purposes of commissioning the terminal with a continuous carrier, the
Entry Channel mode can be set temporarily to Disable. Once this process
is completed, set the Remote back to the desired mode for normal
operation.
