This really comes down to attenuation (and a couple of other factors). I would consider an unbroken distance of 420ft-450ft very safe but you may be able to get closer to 630'ish feet before needing a repeater / extender (depends on environmental variables).
My previous employer used a Patton CopperLink-T 2115 and they never seemed to have an issues with it (http://patton.com) Sent from my iPhone On Jul 5, 2016, at 10:59 AM, Terry Oakley <[email protected]<mailto:[email protected]>> wrote: We are finally replacing our aging router and replacing it with a new (at least new for us) 2911. The current location of our old router was where our old Nortel PBX was located. We are looking at relocating the 2911 into our data centre which will require us to push the PRI signal (we have two) from our demarc room through the building to our data centre, using in house copper cabling. How far have any of you been successful in pushing a PRI/T1 signal and if you needed to put in a 'booster' what booster do you recommend. The distance we are going is between 800 and 1000 feet. I have read that this distance is workable but. I have, in testing, connected the new 2911 to one of the PRI (HDSL) devices and I can see that it connects by running cablelength commands on the VG. If I use cablelength -22db I can get the HDSL light to indicate it is connected but a show controller T1 still shows that controller 0/0/1 is down. So I believe the cable length is too long or I am missing something else. Any assistance and sharing of knowledge would be appreciated.
