Hello,
A small business I support recently had their comdial DX-120 system stop working. When I pick up the hand set and select an outside line, I hear a click every second but no dialtone then after 10 seconds I receive the CALL CANNOT BE COMPLETED AS DIALED message. The clicks sounds like someone is hanging up. Any ideas?

Thanks in advance!

have you verified dial tone at the demark and verified that it is present at the cabinet ?

The Demarc was verified. Dial tone is good all the way to the cabinet.

Thanks

1. Have you reset system? If not--do so.

2. Does every line click?

3. Are all other functions---intercom, voicemail, displays, OK? Are your lines ringing in OK or is the problem just accessing a line?

4. Is the DT at the Demarc with the bridge clips pulled off?? Reset the bidge clips---make sure they are tight and have good DT with and without bidge clips (check both sides of block)

5. Was there something enviornmental that may have brought this about?? Surge, lightning, power outage??

6. Is the system on a UPS that is 5 years old or less??

Get back with us and tell us what you have found out. Good luck.

1. Have you reset system? If not--do so.

System was reset multiple times.

2. Does every line click?

Every outside line clicks.

3. Are all other functions---intercom, voicemail, displays, OK? Are your lines ringing in OK or is the problem just accessing a line?

All other functions appear to work fine. I can page another station, good dialtone until I attempt to access outside line. When calling from cell phone to the system, I get a busy signal.

4. Is the DT at the Demarc with the bridge clips pulled off?? Reset the bidge clips---make sure they are tight and have good DT with and without bidge clips (check both sides of block)

Lines were ran directly to Cabinet - bypassed the 66 block. System does the same thing in different building.

5. Was there something enviornmental that may have brought this about?? Surge, lightning, power outage??

This is do not know

6. Is the system on a UPS that is 5 years old or less??

Brand new APC UPS installed 2 months ago.

Thanks

sounds like a bad CO board, or if it's the primary 4x8 then you need to replace the system next, or add a co board to it as a test. I'm not sure what that should do as I've never had this problem. Standard troubleshooting procedures never change.

Just a SWAG check your co lines see if they are marked as tone; if so change them to pulse and see what happens, possible bad tt senders. Also if you hav'nt already check on the co line side by dialing tone maybe bad tt receivers in the co. Otherwise see what Mark says.

Thanks guys, Just some additional info, the relays on the main board are where the clicking is coming from. If this happens to be the system, I'm thinking it will end up at the shooting range - the warranty is up and the installers want $125 per hour to test. I would love to contact vertical about this but I don't have an installer ID.

Had one do that last weekend.. bad voltage surge from high winds caused the business to have massive electrical problems. Servers, phone system, etc. It's probably a bad KSU. Sounds like it is pulse dialing? The CO sees it as garbage digits thus the "your call cannot be completed as dialed".

PM me the serial number on that thing. Why do you say it's out of warranty? If it was dealer installed it could have as much as a 5 yr warranty.
