[WISPA] Loop start / Ground start PBX Question

2009-08-21 Thread Scott Carullo 

I have T1 from an asterisk box feeding into a channel bank which then 
provides individual analog lines to OLD Hitachi PBX.

Rhino says channel bank should work fine (this is second one and they have 
tested it)

However, this is not the case, less than half the time it works, more than 
half the time the PBX can't pick up the line from the channel bank.  I had 
a ground start line from telco put in to compare - it works with pbx every 
time.

So I am in need of 1 of 2 items.  I prefer a loop start to ground start 
converter (needs to take loop start line and provide out a ground start 
line not sure they make them this direction) or a channel bank that will 
just work providing ground start lines to PBX.

Any suggestions?  Thanks in advance...

You could use an Adtran Atlas800 box to convert or reconfigure your T1s. 
The stock ones come with 2 t1 ports I think. They are cheap on Ebay, and 
I have a couple kicking around too. We used to use them to convert PRIs 
to T1s and before that BRIs to PRIs. It could also replace the channel 
bank if you got the right cards for it.

Try this, reverse Tip and Ring..
Reverse the wires on the ground start line.

That used to fix a lot of problems in my previous life as a telephone guy.




less than half the time it works, more than 
 half the time the PBX can't pick up the line from the channel bank.
