Telephones dead

[highspark]

Hi lads,

too cut a long story short - working on occupied commercial building, had to isolate sub-board to work and test. After isolation and re-energise phones are off. no dialling tone.

At main board there was an mcb saying server do not switch off (thought phones may be fed from this along with broadband). never touched tha-main board - just sub-board which serves the office area.

Anyhow phones have power to them but the lines are dead. on inspection there is a few BT boxes in a cupboard which look as though they control the phones. when isolated do these boxes need to be reset?

When isolated the alarms also went into a reset mode which i managed to do. Absolute nightmare as sub-board has no marking of phone lines or alarms complete joke.

I need a solution to but to the manager as its beyond my knowledge as i am not a telecoms engineer any thoughts on this?

Yes box is similar to those above. Anyhow here's the status. When you ring landline it transfers you straight through to directors mobile phone as it should over the weekend. But you can't ring out from building. Director says you should be able to but the normal system will turn on at 8am tomorrow morning so only then will I know if attend are really down. Why though if there was no landline does it transfer to his mobile as it should?

unless its a fail safe so you cannot lose comunication in event or a power loss it transfers to the mobile?

If it's a Nortel Compact 6x16 then they're cheap as chips, and usually hard as nails also.
I have one in the cellar if you need it!
Programming is also relatively simple from a M7310 phone.

Cyber what exactly are you offering me here? Do you have a diagnosis of what happened and the solution other than getting bt out?

Highspark just looked up the nortel and on power failure they have an emergency fall back to a dedicated line(hence the mobile). They have to then be reprogrammed from an ext fitted with a

BT Meridian Norstar M7208 phone M7208 or ​

equivalent
.

from site: ​

​

The Compact (6X16) system is a self contained unit with 6-RJ11 jacks for the interface for the telephone lines and one male 50-pin amphenol connection is used as the interface for the stations, the amphenol is also used for the connection of external devices such as Music on Hold source, loud speaker paging and a relay contact for auxiliary ringers. The system can be configured with up to six lines with No caller ID capability and sixteen stations non expandable. It has one emergency transfer port used to connect 500/2500 (single line phone) sets in the event of a power failure .It has a built in internal power supply . The administration or the programming can be done from any extension on the system with M7208 phone or a larger phone. The software cartridge includes all administration and call processing features required to operate a Norstar Compact system.

No diagnosis I'm afraid, there's not enough info here to say it one way or another. Simply that if their CCU is toast, I have one here that you can have cheaply to get you out of the brown stuff! If you're local to me (Bristol), I can even install/configure for you.

 

[highspark]

Thanks sounds as though it needs reprogramming then. Well I don't know how to do it so looks like they need a com's engineer

 

[Cyberprog]

If the phones are dead (no dialtone) then the CCU is probably not operating. This would be the first step to figuring out what's wrong. The nortel systems aren't hard to work on, but you do need to be a bit technically minded and know a bit of the lingo in terms of what they're doing.
You'll also need to find out exactly what the CCU is, the Nortel units of that era all look much the same in terms of design, and get progressively more complicated from the 616 upwards...

And you have checked that the unit has powered up. Red led on front
