Help!! Until my new Partner system arrives, I have no working phones...so I dug out an old Bell 620 panel and power supply to use in the mean time....I'm jsut having some trouble with the wiring. If you'll recall, there are 2 small 66 blocks, each divided into four quadrants (1 for each KTU)....in each quadrant, the rows are T R T R A A1 L LG RG RC. It makes sense...except for the fact that there are 2 sets of T/R rows...why is this? Is hte first row for the incoming line and the second for the connection to my keyset?

nevermind, i got it

tip & ring in from CO and t & R out to the phones from the line card.

Don't forget you common audible rc and rg need to be common to each card. you need to wire them together.

I thought that those were strapped internally. The thing works fine..sometimes. I did some very very quick and sloppy terminating w/o the proper tools (I used tweezers..they were convinient), though, so sometimes I can't get dial tone. As long as I keep the KSU turned the right way the wiring works fine. I just have to be careful not to bump it . Good thing this is in my home!

I have an old diode matrix block I can send to you if you need to set up the ringing.
