Prologix Expansion

[PBXmann]

I am getting conflicting information from two vendors. We have a Prologix and would like to install an additional cabinet on another floor and connect them via fiber. One vendor says the Prologix cannot be connected via fiber, must be connected directly using a special cable. The other vendor says it can be connected by fiber.

Any clarification is appreciated! Thanks.

I had the same problem last year. I was informed that I had to use a cable no longer than 6 feet to connect them. I was able to add the cabinet, luckily I had an extra cable from another system. I hope this helps.

It does help, I have a vendor telling me I can connect the two cabinets via fiber 22 floors away in the same building. Time for a new vendor perhaps?

Yes, you need a new vendor. It's a bus cable, 6' max. Essentially, you're adding a carrier, not a "cabinet" in the g3i/si/r sense of the word.

I would probably find another vendor. Seems he's just trying to make a sale. Glad I could be of help.

I also think they can only expand to 3 cabinets (A,B,C)...

Not very scalable - I thought it could only have something like 450 ports... I could be wrong here though.

Thanks,

i dont think it is nescessary for the expansion cabinet to be separeted longer on main cabinet.. because the bus cable of a prologix have a standard length. all you have to do buy the expansion cabinet and cross connect extension cable to the riser then to the distribution..

The reason that u can't have a longer cable is that the Prologix only supports the extention of the TDM bus with an actual parallel cable. With the SI options u have the ability to convert the TDM bus into a optical serial signal. The Prologix doesn't support the boards to do the conversion.

Thank you all. I have received confirmation from two vendors that you are all correct, that fiber can not be used.

Yes, and I've also heard that you can only expand the cabinet to 3 (A,B,C) as well. Good luck with the expansion.
