Service Request (LOS) Signaling
(UDP port 17560)
The TLX640 can broadcast a message over the network when a remote receiver requests attention.
When enabled, the receiver will toggle its TX pin, causing a LOS (loss of signal) event to occur at the
matrix switch. When detected, the TLX640 broadcasts an 'Attention Request' message over the network.
This message contains the IP address of the switch and the port number that detected the request. It is
left up to an external system to detect, decode and act upon this request.
•
32-bits, matrix switch's primary IP address
•
16-bits, 0 for the Upper (or only) matrix switch chassis, 1 for the Lower matrix switch chassis
•
16-bits, port number (list starts from 1, not 0)
•
16-bits, key code in bits 0
– 7, 0x00 and 0xff are ignored

definition files.
There are a few entries in the SNMP configuration file (
/etc/snmp/snmpd.conf
) that users may want
to modify:
•
syslocation
Text to aid in locating the unit
•
syscontact
Name/Phone/email address of a contact
•
trap2sink
IP address/name of a system to receive SNMP traps
The default name used by trap2sink is '
snmp.trap
' and is defined in the file
/etc/hosts
as pointing to
127.0.0.1. The easiest method to change the trap address is to modify the
/etc/hosts
entry and not
change the trap2sink setting in the configuration file. You may have multiple trap2sink entries in the
configuration file to specify multiple trap destinations.
NTP SUPPORT
NTP, or
Network Time Protocol
, is used to keep the internal clock on the switch set to the correct
time.
By enabling this service, users keep the switch
’s clock synchronized to an external time reference.
To use the service, users must have a time-server running on their network or allow the switch to access
a public time-server. NTP configuration is contained in the file
/etc/ntp.conf
Details about NTP configuration may be found at:
