"Works fine" can mean a few things, especially in GTE language:

1. works to spec (never)
2. works as good as the GTE guy feels like making it (probable)
3. they don't want to do anything to fix it (usually)

On frame Relay it is NOT your responsibility to limit your bandwidth.
If you only have a 128k LINE speed then you and GTE both should have
T1's set up with only 2 channels open (64k+64k). If the line speed is
T1 and the CIR is 128k, you are SUPPOSED to be able to burst over that.

I'd place money on either the router(s) needing upgrading, or GTE's
stupidity.

2 channel t1, channelized T1 CSU's at each end... If its a "T1 frame
link with 128k cir" tell them to fix their crap since its NOT your
problem.

Good luck,
