Dialogic D-120JCT Cable question 2

[RyanEOD]

Ok, so here is my current configuration and I am looking for a certain type of cable but I don't know if anyone makes them or if they would have to be custom made.

So this Dialogic card supports 12 analog phones. The card comes with a "pigtail" that has a 25 pair amphenol one one end and the other end breaks out to the 6 dual line jacks. So on a 25 pair cable you are only using 12 pairs.

Ok, so actually we are using 2 of these cards per server. So I get 24 analog lines. But I don't want to run 2 25 pair cables just to run 24 phones. I still want to use the "pigtails" that comes with the cards but I was wondering is there any sort of "Y" adapter for 25 pair amphenol's that I could achieve running 1 cable then breaking it out to two different ones?

I will be doing this at a customer site so while yes I can rig something custom that works I wanted to see if there was anything out on the market right now so it would look neater that my "custom" work.

Thanks for any help in advance.

I just set this up here. Being I have to troubleshoot this every time the vendor has a problem, i used a patch panel as a point of demark for their equipment. In our case we have around 80 lines going into this. So I ran a 100 pair and laid the first 24 pairs down on the patch. I also installed a 1 U wire manager between each bundle. This gives me a place to disconnect from their equipment (thats close) and not have to go back to a closet to trouble shoot.

This being said, i would run two 25 pairs. It would give them room to grow (the next step up on those cables uses 8 on each side of the cards and then 12 per side) and not have to rig it.

You could use a modular jack panel (see SER5L the bottom item at

http://www.sandman.com/pdf/Page50.pdf

for example). Plug in the RJ-25 heads of pigtail #1 into the first 12 ports, and those of pigtail #2 into the second 12 ports. Run a single 25 pair cable with appropriately "gendered" AMP heads on each end. At the destination side, use an octopus cable to break the 25 pairs back out into 6 two-conductor modular plugs (see SER5N near the bottom of

http://www.sandman.com/25pair.html).

Note that you could use connectorized 66M blocks in place of the modular jack panel. These blocks have 12 RJ-14 modular jacks built into the stand-off bracket.

The other way to do it would be to cut the heads off each pigtail and punch the 12 usable pairs onto a 66M block with female AMP connector (used for RJ-21X). Plug one end of a 25 pair AMP terminated feeder cable into the side of the block, and an AMP terminated octopus cable at the opposite end.

Stars for both of you. Great suggestions. I think I am going to just go with the OCTOPUS Cable - 12 4 Conductor Modular Plugs to a FEMALE AMP Connector from Sandman's site. This is exactly what I was looking for. Thanks for the suggestions!
