35 The trunk interface between a network access device and a packet network at data rates greater than 19,200 bits per second. 35 may use the bandwidth of several telephone circuits as a group. 32bis, but with enhanced error-correction it is more reliable. 42, but with the addition of data compression. 90 Provides up to 56,000 bits per second downstream (although usually somewhat less, based on line conditions and other factors). There are proprietary standards as well as the ITU-T standards. These standards mostly came about due to the long delays it took the ITU-T to ratify new standards.
