What is the average speed for a v.90 modem?
If you have a v.90 modem, the average connection speed is about 40-49kbps. If you have a 56K modem and your connection speed is less than 38kbps, the low speed is likely due to a bad line condition, multiple A/D (analog to digital) conversion or Telco issue.

Multiple A/D Conversions prevent v.90 connections The phone line going from the modem is analog until it terminates into the phone company’s central office (CO) or digital loop carrier (DLC). If there is more than one analog to digital (A/D) conversion present on the line (see below), you will not get v.90 connection speeds; instead, you will get v.34 connection speeds. See A/D conversion check for more information. More than one A/D conversion on the line can be attributable to: • Old equipment Some older switches may cause an additional analog to digital conversion. • Pads Pads may be used on the line to make voice communication the same
