Introduction

This modem is intended to be used over any general leased circuits not necessarily conforming to Recommendation M.1020 [1]. A provision for a fast start-up sequence is made to allow the use of this modem for multipoint polling applications if the circuits used conform to Recommendation M.1020.

On leased circuits, considering that there exist and will come into being many modems with features designed to meet the requirements of the Administrations and users, this Recommendation in no way restricts the use of any other modems. This Recommendation does not eliminate the need for manually equalized modems according to Recommendation V.27 or application of other automatically equalized 4800 bits per second modems.

The provisions of this Recommendation are to be regarded as provisional in order to provide service where it is urgently required and between locations where it is expected that a reasonably satisfactory service can be given.
