We have a client who is currently running a 20+ y/o PBX system that we're eventually replacing with an IP Tel solution. My main issue is with 2 remote sites that are 2-3km away from where the VG224 is located.
The said sites are connected to the main office using multi-pair copper lines. The current PBX is being used to supply one analog phone for each site. But as we intend to replace that PBX with the VG224, a hurdle came up... looking at the specs of the VG224, it says that the maximum distance for the analog phone should only be 300ft.
Is there a way to extend this analog line?
Using fiber or data extenders is out of the question. For them to adhere to company standards, no data connection should go to these remote sites, only a single analog phone is allowed. In other words, the data demarcation should reside within the premises of the main office (I CAN'T extend an ethernet line and put a VG204 for each site). Also, the solution should make use of the existing multi-pair copper that's burried. Laying down new sets of cables is probably overkill to supply one phone line per remote site.
So far, my search have brought me to this gadget: Loop Current Booster (http://www.sandman.com/longloop.html) I'm not much a telco guy so can anyone tell me if this will work?
