I have two E1 links , one from PSTN and one from Ericson PBX.
I used CTR4 protocol for both links and D/600 board worked fine.
Now I changed my board to DMV1200 (DM3 board) and changed protocol to NET5.
E1 from PSTN link works fine, but E1 link from Ericson PBX doesnt sync.
I checked CRC (disabled) but did not help.
anyone can help what other settings may change from CTR4 to NET5 ?
how can I check if what is wrong , any tools?
