Hi,
I am having a new IP Telephony installation. I am getting a new voice PRI from my provider. My provider is asking me what is the maximum length of cable he can have from his mux to my voice gateway. Can anyone have any idea on this?
Thanks,
Pete

That depends by cable attenuation and other factors, but consider safe 450 ft for T1.
Hope this helps, please rate post if it does!
