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 Manger, sends autonomous messages, and closes the
connection when finished.
Passthrough
The Passthrough feature of the TimeSource 3500 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:
• COM1 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 3500
• The TID (SID for DCD) is used to identify commands that go to
the DCD product. The TimeSource 3500 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.
• GUI interfaces to the DCD product are not supported through
the Passthrough, only TL1 responses are available.
