Hi,

If anyone out there has connected a Morninstar Express (I know it's old,
but...) to a fast non-frame-relay link, I would VERY much appreciate some
guidance from you on how to do it. (For that matter, former Morningstar
folks... Aidan, you still out there?... are welcome to reply as well :-).

The company I am doing some work for just moved several hundred miles away
from its local ISP and had to get a new one. Along the way it also decided
to upgrade its Internet connectivity from 56K frame relay to 256K
encapsulated PPP over a frac T1.

Now, there is a Morningstar Express router that appears capable of talking to
4 channels of a T1 line (confirmed by someone at Ascend), via a V.35 cable to
a CSU/DSU. There is an ADC Kentrox DataSmart 658 CSU/DSU supplying the data
from those four T1 channels to the router. However, I cannot yet ping the
"customer" side of the ISP/customer connection from the Morningstar router.

I called Ascend support (they bought Morningstar) and tried both the free and
the pay-per-techie-minute support options. The free option has not yet gotten
back in touch with me. The pay-per-techie-minute option came back with the
party line of, "They're not supported. Sorry, we can't help you," although it
sounded like the person I was speaking with was talking with SOMEONE in-house
who knew something about the product.

I think I have the pppd line for the Morningstar correct, and the telco thinks
the CSU/DSU is configured correctly. One or both of us may be wrong, of
course. PPP starts up on the Morningstar and doesn't give any error messages.
A "ps" on the Morningstar shows pppd status as "(connecting, tty0, tty0)"
constantly. It never gets past that. I have set pppd to the highest level of
debug logging and do not see any obvious problems being reported.

Please, if you can help me, I'd really appreciate it. Due to a delay by the
provider in getting the link turned up, the site's connection has been down
(unplanned :-( ) since mid-week last week and everyone (on-site users and
worldwide customers who hit the web page for support issues) miss the net
connection. Even dial-up lines are scarce around the new office. As you can
see, I'm without normal news access (my home LAN is back in Virginia; I'm
currently in Florida) and am posting via dejanews.

PLEASE REPLY TO ME AT he...@appx.dyn.ml.org if you have any hints on how to do
this. AdvThanks,

Helen C. O'Boyle

I would sugest you have the phone company run a stress test to check out
both ends of the circuit. A Remote loopback on the port in question
followed with an All 1's or 511 BERT would also work. Check performance
registers for the past 24 hours. You need to first assure that the
channels assigned to DSU's data port are running error free. The next
step would be to run a DTLB from the DSU to the router. The router must
have HDLC encap working fo the router to see the loopback. The router
should be able to see the loopback and the same number of RX frames as
TX frames. I am assuming the Morningstar is not an edge router.

If the DTLB passes, your router is misconfigured. If it fails, the DSU
port or the router port is bad or misconfigured. You can figure this out
by swapping ports.You may also have a bad cable. Good luck!
