Appl. No.:

11/337186

Inventors:

Mike Le - Huntington Beach CA, US
Keith R. Jones - Laguna Niguel CA, US

Assignee:

Mindspeed Technologies, Inc. - Newport Beach CA

International Classification:

H04B 10/00

US Classification:

710 8, 398135

Abstract:

An optic module is disclosed having a shared bus interface, a transmit disable line, a memory and control logic or a processor configured to facilitate address modification via a bus shared by multiple optic modules. A single housing may contain multiple modules, all of which are preferably accessible via a shared host via a shared bus. Standard compliant modules share a common address, which inhibits communication with only a particular optic module, via the shared bus, in a housing containing multiple optic modules. Using a common message to all modules to treat a transmit disable line as a module select line, a single module may be active during an address re-write operation. This process may repeat until all the modules within the housing have unique addresses.

Abstract:

An optic module is disclosed having a memory configured to store data. To selectively control access to the memory and data stored in memory, a method and apparatus for memory access control is provided which creates access levels. The access levels include associated passwords, and read/write capability control, and address access range. During use a technician or other party would enter a password via an interface and the entered password is compared to the password associated with each access level. If a match is not found, then access to the memory, a hence data within the memory is denied. If a match is found the technician gains access to the data stored in the memory address range associated with the access level. Read and write access may also be granted or denied.
