💖 ISDNSYNC 💖

okay bestie, so this is the manual page for isdnsync from section 1 of the manual, and it's genuinely such a clever little thing. like, a tiny tool doing a huge favor for your E1 line. let's get into it 🎀

✨ NAME ✨

isdnsync — use a cheap HFC-S card with the public telephone network as frequency standard for your E1 line 💅

🌸 SYNOPSIS 🌸

isdnsync <card>

🦋 DESCRIPTION 🦋

so isdnsync is a small tool — like, small small — and what it does is it initializes a cheap HFC-S ISDN-Card so that bit and frameclock are present on 2 IC-Pins. 🫶

and why do we care?? because those signals can be used to feed an HFC-E1 card with a very exact clock. it's giving "borrow the public telephone network's timing and make it your whole personality". iconic. the cheap card becomes the frequency standard, the E1 line gets the accuracy, everyone eats. 🔥✨
