Appeal No. 96-0974
Application 08/024,299
DECISION ON APPEAL
This is an appeal under 35 U.S.C. § 134 from the
examiner's rejection of claims 1, 2 and 5-8 under 35 U.S.C. §
102 and rejection of claims 3 and 4 under § 103. No claims
stand allowed. We reverse both rejections.
The invention concerns detection of a broken line in a
multi-line cable and switching the transmission of data from
the broken line to an unused extra line. Claim 1, which is
representative, reads as follows:
1. An automatic broken cable detecting and
switching apparatus, comprising:
means for discovering the presence of a defective
line of a cable having a plurality of lines during a
power-on period by sequentially checking each of said
lines;
warning display means for displaying an identifi-
cation of the defective line upon said discovery;
line selecting means for automatically switching
transmission of data from said defective line to
another line;
means for again checking the presence of a defect
in other lines of the cable after switching said
defective line to said another line; and
means for automatically resuming transmission of
data upon completion of the checking.
