Passthrough - Symmetricom TimeSource 3600 User Manual

Chapter 1 Overview of the TimeSource 3600
Functional Description
Two additional ports communicate with Element Managers, which may have NMS,
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 Manger, sends autonomous messages, and closes the
connection when finished.

Passthrough

The Passthrough feature of the TimeSource 3600 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 of the TimeSource 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 3600
The TID (SID for DCD) is used to identify commands that go to the DCD product.
The TimeSource 3600 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.
