On an Avaya IP Office customer system, only three out of four analog trunks are connected to a provider. Which solution for the fourth trunk port would not impact the operational trunks?

Question

Options

• AThe Line Appearance ID should be set to 700
• BNo settings are needed
• CThe Line Group ID needs to be set to Default
• DThe Trunk has to be set to Out of Service using SSA

• A
  2% (1)
• B
  8% (4)
• C
  13% (6)
• D
  77% (37)

Explanation

Setting the fourth trunk port to Out of Service via SSA (System Status Application) isolates it cleanly from the system's call routing and signaling without altering any configuration that could affect the other three active trunks - it's a targeted administrative action that signals "this port is intentionally unused" to the system.

Why the distractors are wrong:

• A (Line Appearance ID = 700): Changing the Line Appearance ID modifies how the trunk is presented on extensions, which could create routing conflicts or confusion across the entire line group, not just the unused port.
• B (No settings needed): An unconnected but active trunk port will generate alarm conditions and error logs as the system repeatedly tries to poll or use it, which can disrupt system stability.
• C (Line Group ID = Default): Putting the unused trunk into the Default line group would make it eligible for outgoing call selection, causing failed call attempts when the system tries to seize the unconnected line.

Memory tip: Think of "Out of Service" like putting a "Do Not Use" sign on a door - SSA lets you administratively close that specific port without touching the doors (trunks) that are already open and working.
