6.1
Overview of Digital Diagnostic Monitoring I nterface
The TXN31115D2 Optical Transceiver supports the 2-wire serial communication
protocol. The TXN31115D2 Optical Transceiver has a digital diagnostic monitoring
interface that is an extension of the serial ID interface defined in the Gigabit Interface
Converter (GBIC) specification and the SFP Transceiver MultiSource Agreement (MSA)
referenced in
Section 1.0, “Introduction” on page 7
.
Standard SFP serial I D interface.
The standard SFP serial ID interface (the
memory map for which is in
Table 12, “Memory Map – 2-Wire Address Range
Descriptions” on page 18
) provides access to identification information using the 8-
bit address 1010000X (A0h). The serial identification information describes
information such as the following for the TXN31115D2 Optical Transceiver:
capabilities, standard interfaces, and manufacturer information.
Digital diagnostic monitoring interface.
The digital diagnostic monitor interface
(the memory map for which is in
Table 12, “Memory Map – 2-Wire Address Range
Descriptions” on page 18
) is an extension of the standard serial ID interface. This
interface, which uses the 8-bit address 1010001X (A2h) reserved for optical
transceivers, allows real-time access to device-operating parameters while leaving
unchanged the original serial ID memory map A0h. The digital diagnostic
monitoring interface is backward compatible with both the GBIC specification and
the SFP MSA.
Note:
For details on the 2-wire addresses A0h and A2h, refer to the SFF-8472 document
referenced in
Section 1.0, “Introduction” on page 7
