1U SHELF TYPE MAS-2
WITH ASYNCHRONOUS PROGRAMMABLE MODEM MAFP - Rev. 9 (January 2018)
5/39
In order to make commissioning easier, the front plate of the modem features elements
necessary for:
the adjustment and measurement of the transmission and reception levels,
the configuration of the modem such as the RTS-CTS delay selection, test selection, etc.,
the optical indication of the tests and logical signals of the interface.
the optical indication of the equipment status.
