Low-cost telecom protection?

    Has anyone any ideas for a low-cost telecom protection which can pass
    regulatory tests such as FCC Part 68 and ITU K.20/K.21? I'm currently using
    a combination overcurrent fuse and an overvoltage protector (thyristor type
    Bourns TIPS). These are pretty expensive, though, and I'm looking for some
    ideas to lower costs.

    Now, I've seen some designs which only have a varistor (MOV) inside, but I
    doubt that such a design would pass regulatory tests. And replacing the
    overvoltage protector with a gas-discharge device probably won't be much
    cheaper either.

    Anyone have any experience with this? Thanks in advance!!

    What particular section? Or what type of circuit (service)? Part 68 cuts a
    broad swath. Are you working on CPE or Network equipment?

    In the 'been there-done that' scheme of things, several years ago I went to
    the DOC( Canadian eq. of FCC) about the regs of 'type approval' for a 'modem
    like device' connecting to the phone lines. I was sent a package that
    weighed about 15 pounds. More 'gobbltygook' than I cared for.
    It was far,far cheaper to reengineer the project to use standard( at that
    time) 8 bit ISA 2400 baud modem cards,which were already approved.That was
    20 years ago and they are still working....

    Just another way to look at the project...
