1-18 Functional Description FCD-E1LC Ver. 1.0
• Send a report only upon the detection of a major alarm.
• Reporting disabled (no dial-out function).
When it is necessary to report an alarm condition, FCD-E1LC initiates the call
setup, and then, after the destination answers, sends the complete contents of
the alarm buffer. Following the transmission of the alarm buffer contents,
FCD-E1LC disconnects automatically.
To increase reporting reliability, you can define the number of dialing retries, and
an alternate directory number to be called in case the primary directory number
cannot be reached. If nevertheless the call cannot be established, the full
contents of the buffer will be sent the next time a call is set up.
To expedite the handling of alarms and reduce the information load during
system malfunctions, the system operator can mask alarm conditions, to prevent
continuous reporting of known alarm conditions, e.g., during maintenance
activities.
Statistics Collection
FCD-E1LC collects and stores E1 port statistics in compliance with ITU-T Rec.
G.706, G.826, with local support as per RFC 1406.
These statistics can be retrieved either from the management station (RADview),
or via the supervision terminal.
The management subsystem exchanges information and sends commands
through several ports:
• The communication with the various internal subsystems of the FCD-E1LC is
performed through the management address and data buses. The subsystem
also controls the front-panel indicators.
• The communication with the supervision terminal is performed through the
front panel RS-232 serial port interface. This port is used to perform the
initial configuration of the FCD-E1LC, using any standard ASCII (“dumb”)
terminal (or PC running a basic communication or terminal emulation
program). After the initial configuration, the port can be used to control and
monitor FCD-E1LC operation.
• When inband management is enabled, the management subsystem transmits
and receives management traffic through the E1 main and/or sub port. The
communication with the E1 port is made through the TDM bus.
Power Supply Subsystem
FCD-E1LC has a universal wide-range power supply, which enables operating on
100 to 240 VAC, 50/60 Hz, or -48/-60 VDC.
