Digital Phones over Fiber

[tomskillman]

We currently have a CS1000 consisting of 3 cabinets serving 4 buildings. The connections to other buildings are via 2 overhead cables - 1 100pr and 1 50 pr. The third building is served with a 25 pair from the building served by the 100 pr. Is there a way to convert these exterior runs to fiber? What would like to do is use some type of MUX to give me the pairs I need at the far end. I could easily pull cable from the 100 pair building to the 50 pair. So, what I have is 26 digital and 20 analog stations at the end of these cables. Is there a way to put this over fiber without moving one of the CS1000 cabinets to the other building? Currently the stations are spread over the 3 cabinets.

Thanks.

You could install Remote Office 9150 units in the three buildings, along with RLC cards in the cabinets for the digital sets, then all of your communication would be IP between the RLC card in the switch and the 9150 in the far-end building. With the correct number of DLP cards each one will handle up to 32 Digital sets.

2 mile fiber kit will also extend an entire cabinet over fiber. This would be a new daughterboard and reciever card.

What do you use the analog lines for? Just phones, or modems/fax? I don't believe the Citel products extend analog dialtone, just digital. Been a while since I've worked on one of those. You could do ATAs on the back of the digital sets, but I remember those barely working for fax machines when using a 9150, and not working at all for modems off the 9150's. Never tried the ATA route using a MCK/Citel box.

You could go with a fiber IP expansion as well as what tnphoneman suggested. What you use the analog dialtone for will be your deciding factor. It might end up being less headaches to move the cabinets.

The analog are either phones or ringers. There are 2 places we have bells on the analog lines (Storerooms). The other places are where we use a phone that is harder for them to damage (no display). Sounds like either run new copper or move a cabinet....
