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? Nick
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.

Check the crossover cable.

Hi. Just for grins, reverse the BNC's. You could have the tx and rx crossed, happens all the time on ds-3's. Also, with the BNC's unplugged and hanging, You should have a Yellow light on the Hdsl Box (I've always called that a smartjack, but we call football soccer, so what do we know? :) ). If you don't get a yellow light with the BNC's hanging then the smartjack probably has an internal loopback set and you need to give your telco a call to clear it.
