ROADM Features
Automac In-Service State
When equipment or facilies or both are preprovisioned, before equipment installaon, the equipment or
facilies or both are placed in Automac In-Service (AINS) state. When the equipment is installed, the
equipment or facilies or both are placed In-Service (IS).
Note: If the installed equipment does not match the preprovisioned equipment type, an MEA condion is
raised.
Automac Line Control
The Automac Line Control (ALC) feature automacally adjusts the total opcal output power and keeps the
power of each channel constant and at the appropriate level. This feature ensures that manual adjustments are
not required when channels are added to or dropped from the WDM facility. ALC ensures that other channels do
not suer performance losses (trac hits) when a channel is added to or deleted from the system.
Automac Gain Control
The Automac Gain Control (AGC) feature automacally adjusts the gain of each channel to a constant and
appropriate level. The opcal amplier in the L100 Blade connuously monitors the composite input and output
signal power. A control circuit maintains a constant target gain using preamplier and postamplier variable
opcal aenuators.
Automac Laser Shutdown
The Automac Laser Shutdown (ALS) feature automacally shuts down the laser when the postamplier detects
a signal loss and an Opcal Supervisory Channel (OSC) loss.
Automac Power Reducon
The Automac Power Reducon (APR) feature automacally reduces the laser power when the postamplier
detects high reecon on its output port. APR is triggered when the reported Output Return Loss (ORL) is less
than 17.6 dB. Normal operaon restarts when ORL exceeds 20.6 dB. APR mode limits output power to 3 dBm
regardless of current provisioned sengs and input power. It does not prevent operang at lower output
powers.
Simple Network Management Protocol Trap
A Simple Network Management Protocol (SNMP) trap is an event nocaon that is sent from an SNMP agent to
one or more SNMP managers when an extraordinary event, for example, an alarm, occurs. The SNMP agent
generates SNMP traps for all standing condions unless the standing condion disables the agent.
