1 Introduction
Thank you for choosing the PAMSPAN501x as your broadband access solution. This
manual will help you with the setup and configuration of your product.
1.1 PAMSPAN501x Overview
The PAMSPAN501x takes advantage of the latest technology - Extended Rate Bonded
SHDSL – opening up unprecedented possibilities for symmetric transmission.
The PAMSPAN501x comes with EFM bonding or ATM m-pair bonding; higher packet
transport allows symmetric data rates of up to 5.69 Mbps, 11.38Mbps, 17.07 Mbps, or
22.76Mbps over standard 2-wire, 4-wire, 6-wire, or 8-wire telephone lines, respectively.
EFM different rates between pair 4:1 means that speed ratio of 4 between the fastest and
slowest link of a group (according to IEEE 802.-2004)
The PAMSPAN501x is a solution that enables enterprise users to enjoy long distance, high
bandwidth and symmetric data transmission.

Features
Rate and Reach Improvements
The symmetric transmission rate can be up to
5.69 Mbps, 11.38Mbps, 17.07 Mbps,
or 22.76Mbps over standard 2-wire, 4-wire, 6-wire, or 8-wire telephone lines,
respectively.
Note: When one pair fails while operating in multiple pairs mode, the connection will
still be maintained. The other pairs can still operate at the maximum rates.
