Appl. No.:

9/461615

Inventors:

Neal W. Lewis - Raleigh NC
Lawrence F. Bizga - Durham NC

Assignee:

Nortel Networks Limited - Montreal

International Classification:

H01R 1216

US Classification:

361788

Abstract:

A pin connection arrangement spanning a series of slots on a backplane 1 printed circuit board. The arrangement allows replaceable printed circuit board assemblies to be paired or mated while further allowing the printed circuit board assemblies to vary incrementally in width. The printed circuit board assemblies can be one slot wide 10a, 10b, two slots wide, 12a, 12b, three slots wide, 14a, 14b, on up to `n` slots wide while being paired to a mate for sparing purposes. Backplane 1 provides a direct connection between paired printed circuit boards. The arrangement(s) allow expansion of printed circuit board area and volume while supporting paired applications that require only a single slot for a backplane connection per printed circuit board. Backplane 1 can be used for different width printed circuit board assemblies. This is accomplished by a series of pin connectors 18 and traces 16 on backplane 1 that link slot pairs (single wide), every other pair (double wide), every third pair (triple wide), and so forth to the desired level of printed circuit board width.

Abstract:

An interactive electronic module (IEM) is adapted as a retrofit module for use in modular network equipment to provide real time analysis of trunk line signal performance and to detect trunk line signal faults, the IEM including a faceplate display panel accessible to the network operator for displaying the detected signal faults and for providing operator access to the IEM to command the display of selected trunk line faults.
