back in my "real" telephone days, a red alarm meant the near end was not receiving signal. A yellow means the far end is not receiving signal.

Howdy -

I'm trying to get a Malaysian PRI E1 up on a TE410P, with no luck. Right now, the setup is

Telco -> HDSL -> WorldDSL UTU801-> 2 BNC E1 -> balun -> crossover -> TE410P

Right now, the CSU/DSU-ish WorldDSL box has a green light indicating E1 sync, but the TE410P shows a red alarm. I checked the card by plugging the crossover from port 1 to port 2 on the 410 (it worked fine). It I change any of the cabling (i.e. swap things around), the green light goes off.

I have my suspicions about the balun (http://www.ctcu.com/catalog/datacom/balun.pdf). Would a DB15F-RJ45 converter be better the the BNC-balun-RJ45 arrangement we have now?

Here's my zaptel.conf:
span=1,1,0,ccs,hdb3
bchan=1-15
dchan=16
bchan=17-31

The telco line IS working; it was tested and put in a couple of days ago. Any ideas why this isn't working?
