QAUX interface:
It is provided as an additional TMN communication interface for message exchange between the NE and
a Remote OS station based on the use of a 2 Mbit/s proprietary protocol. It can be physically terminated
on a 2 Mbit/s auxiliary channel on the SERVICE card.
Q2 interface:
A mediation function interface is provided to connect the 1660SM to non–SDH network element
The RS–485 interface and the cable connector are provided on the CONGI card.
RE, RA, HK and leds interface:
RE consists of parallel I/O signals used for remote alarms that can be accessed on the CONGI card
RA is dedicated to send commands toward the rack to light up the relevant lamps.; the physical interface
is available on the CONGI card.
By pressing a push button is possible to store an alarm;
HK consist of parallel I/O signals used to handle housekeeping signals (for example alarms received from
