Maybe you could try this: 
use strict;
use warnings;

my $line;
while (<DATA>) {
    $line = $1 if /^\s*MSISDN=(\d+);/;
    if (/\s*CF=([\w-]+?-(?:NONE|\d+))/) {
        my $add = $1;
        $add =~ s{(\d+)$}{1/1/1/$1};
        $add =~ s{NONE}{1/1/1/0};       
        $line .=  ",$add";
    }
}
print "$line\n";

Please note that your specification and your example output are inconsistent. Your spec says "1/1/1/0" (three 1s) and "1/1/1/49690300" (three 1s, and the trailing 0 removed from 91496903000), and your example says "1/1/1/1/0" (four 1s, not three) and "1/1/1/1/91496903000" (four 1s and the complete number 91496903000). You'll have to adjust the code in accordance with your actual needs.
