Cyclades config

We have spent much $$$ on a setup for a T1 using a Cyclades-PC300/TE card.. they’re not cheap! However it shows no signs of working at this point. I have contacted our provider and they said to use B8ZS/ESF. The line-protocol is Cisco-HDLC. Have it set for external clock. Line build out is 7.5db. Rx threshold is short-haul. Active channels is set to ‘any’ This is a clear-channel circuit so we can get 1.544mbps. Everything syncs up perfect and shows no framing errors or alarms. So it appears to be working.

So… for this setup:

1.) Cyclades interface IP address is x.x.x.17/30
2.) Default route is x.x.x.18

No data making it through, though.

Question:

Do I have to set the Cyclades interface to x.x.x.17/32 with the network address x.x.x.18 and broadcast 255.255.255.255 with this setup as MT’s docs only show an example for sync-ppp line proto?

What else could I be missing?

/ip addres add address x.x.x.17/32 network=x.x.x.18 interface=cyclades1

Why does it work this way? It’s not a PPP connection, only a 30 bit subnet. Or is that just how it works in the Linux kernel?
