(since the MA management is not operative in this case) it is necessary to power
off/on the device and then to set the DIP switches to LST On to perform a link
segmentation test. In GSM1010/MA the LED LST (FO) is steady red light to imply
that the TP>>FO is constantly preset to LST ON (Test Mode).

12 - MA Concepts
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.

enabled devices are deployed at both ends of the fiber link, they automatically
