10 – MA Concepts and Functions
(
GSM1000/MA &GSM1010/MA
)
The MA™ (Micro Agent) is an on-chip management system providing the monitoring and
management of remote access devices without the need of an expensive SNMP agent module.
The MA™ does not require an IP address
The chip is embedded in both the remote units, mostly referred to as a CPE, and in the access
concentrator device deployed in the access node. A unique secured in-band management
protocol allows the two devices communicating between themselves over the fiber link bi-
directionally, therefore both monitoring and management commands can be remotely
performed on the CPE. Control frames are not forwarded to data ports

When
MA™
enabled devices are deployed at both ends of the fiber link, they automatically
learn about each other’s presence and begin providing full remote management functions
within 20 to 30m.seconds from the moment the link has been established. However, if an
MA™
enabled devices cannot complete such handshake within that time, it concludes that the
opposite end device is not
MA™
enabled, subsequently it bypasses its special functions and
operates like a standard, straight forward access device. Therefore there are no interoperability
issues between network devices which have
MA™
chips embedded in them and those that
have not.
The following management functions are available for the GSM1000/MA and through an
MA™ enabled and SNMP managed MetroStar:
•
Device status: display the device ports basic status and configuration settings.
(Port 1 and 2: Link status (SX, LX), Signal Detect (SX, LX), LST mode, Loop back
status (LX, port 2) and upstream bandwidth.
(also shown are the device Temperature and Firmware revision level)
•
Device Control: provides the user with options to set the channel’s description,
to invoke the LB/LST control, set upstream bandwidth, enable/disable channel,
and to restore the device’s defaults setting.
The GSM10x0/MA devices generate a " Remote Power Failure" signal upon power
failure. The attached GBE module will show in its Module status this condition
(Remote device Power "fail"). The term "Remote Power Failure" in this manual is
sometimes referred to "Dying gasp" or "Last gap" by the industry as well in the
product specifications.
