Page 21: Alarms
Section 3. Operation 3.2. Alarms The multiplexer is equipped with emergency alarm interface. The emergency alarm interface is designed for switching on external executive device (such as a bell, buzzer, indicator on control panel, etc.) during emergency. Alarm relay is used in the "dry contacts" mode (that is, its contacts are isolated from all electrical circuits in the multiplexer). The following situations are considered emergencies: • power failure; • loss of signal or frame synchronization in the link port; • loss of signal in at least one of the E1 ports used (in "In use" state"); • alarm signal received from external input sensor of remote device. Alarm from external input sensor for transmission to remote device is generated either when the sensor contacts close (this mode is enabled by default), or when they open (alarm generation mode is described in the "Sensor input" subsection of section 4.8 “ "Configure" menu”). If the multiplexer is installed in unserviceable room, then external input sensor contacts may be used, for example, for transmitting climate sensor signal, door opening signals, etc. The alarm connector pinout is presented in "Alarm connector" subsection of section 2.5 "Cable connections". © 2006 Cronyx... -

An example of the main menu is presented in the picture: Cronyx FMUX / 4E1-SAT-SNMP revision A, 28/04/2006 Mode: Normal; Sensor=Open Link: 8448 kbps, Ok, Cable cross V.35 DTR, RTS, ETC, DSR, CTS, CD, RXC 1. - Page 28 FMUX/SAT Multiplexer • "LOF" – loss of frame synchronization; • "AIS" – AIS signal is being received; • "Loop" – local loop enabled on the link: the received signal is turned back; • "Remote loop" – request for remote loop enabling. When BER tester is enabled, the "Link" line also shows information about test results: • "Test pattern not detected" – if the test pattern was not detected in received data; • "Test error rate=..." – error rate in received data, 10 to 10 (shown in place of "Test pattern not detected" message); • "Time total/loss=.../..." – total test time (days hours:minutes:seconds)/time in "Test pattern not detected" state (seconds); • "Bit errors=..." – data error counter; • "Code=..." – test pattern code. © 2006 Cronyx...

Press “R” to toggle screen refresh mode between overlapping and redraw. In overlapping mode the screen will not be cleared when information is updated. To reset statistics counters to zero, press "C". "E1 port statistics" line contains current session number and time passed from switch- ing on or restarting the multiplexer. Session number increments every time the device is restarted. Description of lines in the upper part of the screen, including "Mode" and "Link", is presented in "Upper level menu" section. Further, E1 port states and statistics counters are displayed: • "CV" column – the number of code violations; • "Receive" column (under "-Errored seconds-" caption ) – contains the number of seconds during which frame synchronization was lost in the link. ("Transmit" column is not used for this model, and contains dash for each E1 port.) The ports' "Status" is shown as a set of flags: • "OK" – normal state, frame synchronization present; • "LOS" – loss of signal in the link; • "AIS" – link failure signal is being received (the "all ones" code); • "Loop" – loop enabled; • "Tloop" – tributary loop enabled. States are not shown for unused ports. © 2006 Cronyx... -

"Error insertion rate: ...” command selects error insertion rate, from 10 to 10 er- rors/bit, or disables error insertion mode, in this case "No errors inserted" message is displayed in place of numeric value. "Insert single error" command inserts single error. "Test pattern: ...” command allows using either pseudo-random code as a test pattern, or selecting fixed 8 bit code. Test results information is displayed in the following lines: • "Time total: ...” – total test time; • "Sync loss: ...” – time during which test pattern synchronization was lost; • "Bit errors: ...” – bit error counter; • "Error rate: ...” – error rate in the received data, from 10 to 10 . If testing is not en- abled, "Testing disabled" message is displayed in this field, if no test pattern is detected in the received data, the "Test pattern not detected" message is shown.
