Posted on 2011-03-18
Last Modified: 2012-05-11
Well I just took over a new network and have never dealt with any other phone systems other than VOIP. I dont know what kind of system I have or how to work on it. I am needing a good crash course on this. I have attached pictures. Can anyone tell me what kind of phone system im dealing with and whats the best course for learning it and being able to troubleshoot. I have NO experience with this type of phone system and couldnt tell you a single thing about it. I hope someone can help and if not thanks anyway. I hope everyone is doing well.

well I can't tell you anything about your phone switch as I cannot read any markings.  The switch on the left is most likely the carrier's T1 switch
The wires are all connected to 66 blocks nothing special there.

The big metal servers are what you want to look at.

Most likely it is all Command line and you telnet to or ssh to or it may even have a web interface or may be as bad as console only.  

For the most part these old phone servers you just leave em be and just add extensions and change mailboxes as necessary until you replace them with a new system.

IMHO you might want to get a phone vendor who knows this to sort it through to get you started.  I did a quick google on the dk242 and I have never heard of this one but of the hardwire ones I ve used have always been the big companies like avaya or Nortel.

The phone system is a Toshiba DK series.  The 424 manual can be found in several places:
It supports a T1 telco interface (the black box on the left), digital telephones (on the bottom of the phone will be a model number with DK or DT) and older electronic telephones (EK in the model number) and analog ports.  The Digital phones use one pair of wires per port.  One of the 66 blocks will have the ports wired from the circuit card in the KSU (the big boxes on the wall) -- then cross connected with the blue/white jumper wire to a 66 block that has the station cables terminated on them.  The cross connect is wired to the "first pair" of the station cable - it will come out on the middle two pins of the jacks at the workstations.  Analog devices wire to the same pair.
