Looking into getting DSL from Verizon. Nowadays they ship a self-installation kit with the combination router/modem, filters, and phone splitters.
They say not to connect the modem until the day service starts. However, I know that once the service starts the DSL signal creates noise on the phone line, which the DLS filters eliminate for the phones.
My question: Is it ok to install the DSL filters onto the phones before the DSL service starts? I figure it'd be ok, since they filter out a signal that's not being used by the analog phone service anyway, but I'm not certain.
Anyone ever use a DSL filter on a phone line that didn't have DSL service? Did it affect the phone service at all?
