Alarm Interface
The microprocessor delivers alarms to normally open dry-contact type connections. Alarms
are also indicated by the front-panel status lamps, and TL1 messages reported via the
communication ports.
Ethernet
TimeSource 3000 has one physical Ethernet port with six virtual ports to carry TL1
commands, responses, and autonomous messages between the TimeSource 3000 and an
external terminal, or an Element Manager, or both. The user can configure the IP address,
subnet mask, and gateway address for the Ethernet ports.
Four ports (5001, 5002, 5003, and 5004) are configured to act as though a serial-port
communication terminal were connected to them. These ports communicate TL1 commands,
responses and autonomous messages.
Two additional ports communicate with Element Managers, which may have NMS,
TimeScan, TimePictra, or similar software. An Element Manager establishes a connection
with one port (5551) for TL1 commands and responses. Another port (5550) establishes a
connection to an Element Manager, sends autonomous messages, and closes the connection
when finished.
Communications Ports
Three RS-232 serial communications ports carry TL1 commands, responses, and
autonomous messages between the TimeSource 3000 and an external terminal.
Passthrough
The Passthrough feature of the TimeSource 3000 allows the unit to front a DCD product to
provide one management interface for a user site. Passthrough allows a user to do the
following:
•
Provide a no download exclusion for the Passthrough port
•
COM 1 or COM2 is connected to the DCD product
•
The user port can be any unused port, including the Ethernet port
•
Messages can pass from a user to the DCD product and from the DCD product to a
user through the TimeSource 3000
•
The TID (SID for DCD) is used to identify commands that go to the DCD product.
The TimeSource 3000 passes any TID not its own through to the DCD product. In
the reverse direction, all commands received from the DCD product are passed
through to the user.
