Tell whoever's got the T1 that 1967 is way behind us and get a new
interface.
Problem eliminated LOL

I have to generate an alternate mark inversion signal on 1.544 MHz with
every 193rd bit following a t1 framing sequence.
Sure wish a 555 could do that.

Find a 555 timer ... I used many in the olden day when radioshacks were
king LOL!

I am thinking of using some shift registers instead of using the PI
output directly as the timing signal.
Use the PI to load them.
I love me some hardware design anyhow....

Other than setting the process priority, you may need a custom kernel.

Anyone know how to get my program to run on bare metal?
Or at the very least tell Linux that my program is the most important
thing in the world and service it above all other things.
I am trying to create a timing signal with the Pi. It is doing it
but the jitter is pretty bad.
I have researched trying to use an interrupt but there is a pretty
low limit on how many times per second you can fire a hardware
interrupt.
Too low for my application.
