Abstract

A system and method determines the environmental configuration of telecommunications equipment having interchangeable components to provide an alarm if an improper environmental configuration exists. A configuration engine associated with the network management system of the telecommunications equipment determines the environmental rating of components added to or removed from the telecommunications equipment by querying flash memory associated with the component. If components designed for controlled environmental conditions and components designed for uncontrolled environmental conditions are both present in the telecommunications equipment, then component engine 30 sets the alarm to alert the user of an improper environmental configuration.

Claims

1. A method for determining the environmental configuration of telecommunications equipment having interchangeable components, the method comprising:

configuring the telecommunications equipment with plural components, each component having one of a controlled rating if the component is for use in a controlled environment, an uncontrolled rating if the component is for use in an uncontrolled environment or a both rating if the component is for use in both a controlled environment or an uncontrolled environment;

storing a component rating for one or more components in memory associated with the component;

detecting the rating for each component added or deleted to the telecommunications equipment;

determining that an improper environmental configuration exists if one or more components has a controlled environment rating and one or more components has an uncontrolled environment rating;

setting an alarm if the improper environmental configuration condition exists; and

clearing the alarm if an improper environmental configuration does not exist.

2. The method of claim 1 wherein storing a component rating further comprises storing a rating for each component in flash memory associated with the component.

3. The method of claim 2 wherein the flash memory comprises EEPROM.

4. The method of claim 1 wherein detecting the rating further comprises:

determining whether an added component has a controlled environment or uncontrolled environment rating stored in memory associated with the component; and

assigning a both rating to components that do not have a rating stored in memory associated with the component.

5. The method of claim 4 wherein detecting the rating further comprises:

storing the rating for each component added to the telecommunications equipment in memory associated with the telecommunications equipment; and

deleting the rating for each component removed from the telecommunications equipment from the memory associated with the telecommunications equipment.

6. The method of claim 1 wherein the telecommunications equipment comprises a digital subscriber line access multiplexer.

7. The method of claim 6 wherein the digital subscriber line access multiplexer comprises a chassis backplane having a both rating.

8. The method of claim 1 wherein the controlled environment comprises a central office.

9. The method of claim 1 wherein the uncontrolled environment comprises an outdoors environment.

10. The method of claim 1 wherein the ratings are associated with capability for operations in predetermined temperature environments.

11. A telecommunications system comprising:

plural interchangeable components, each component having a controlled rating if the component is for use in a controlled environment, an uncontrolled rating if the component is for use in an uncontrolled environment or a both rating if the component is for use in both a controlled environment or an uncontrolled environment;

a component engine operable to determine the rating of each component;

a network management system interfaced with the component engine, the network management system tracking the rating of each component; and

an alarm interfaced with the network management system, the alarm operable to provide notice of an improper environmental configuration if the network management system detects a component having a controlled environment rating and a component having an uncontrolled environment rating.

12. The system of claim 11 wherein the plural interchangable components comprise a backplane bus having a rating of both controlled and uncontrolled.

13. The system of claim 11 wherein the plural interchangable components comprise digital subscriber line cards having one of a controlled rating or an uncontrolled rating.

14. The system of claim 11 wherein the interchangable components comprise optical interface cards having one of a controlled rating or an uncontrolled rating.

15. The system of claim 11 further comprising list memory associated with the component engine and the network management system, the list memory tracking the environmental rating of interchangeable components interfaced with the telecommunications system.

16. The system of claim 11 further comprising flash memory associated with at least some of the interchangeable components, the flash memory storing the environmental rating of its associated component.

17. The system of claim 16 wherein at least some of the components having a both environmental rating lack flash memory, the component engine assigning a both rating when no rating is stored on the component.
