Ethernet
TimeSource 3100 has six Ethernet ports to carry TL1 commands, responses, and
autonomous messages between the TimeSource 3100 and an external terminal, or an
Element Manager. 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, OSMF,
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.
Passthrough
The Passthrough feature of the TimeSource 3100 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 3100
• The TID (SID for DCD) is used to identify commands that go to the DCD product. The
TimeSource 3100 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.
Note:
The TID of the TL1 command must be the SID of MIS.
• DCD is fully managed except for firmware download.
