INTRODUCTION
Today, means of communication employing state-of-the-art hardware and software solutions evolve
rapidly. New communication devices, which utilise alternative data transmission principles, pose a problem of
their integration into existing communication networks. The solution is to use special equipment, which
interconnects diverse segments of networks. Currently, such equipment is represented by digital gateways. They
allow gradual transition from existing communication networks to more efficient ones with alternative operation
principles.
At present, IP networks are considered to be the most efficient when they are weakly dependent from
data type and transmission medium and at the same time are flexible and manageable. Designed and
manufactured by Eltex, SMG digital gateway is intended for interfacing of traditional communication networks
based on the link switching principle with communication networks used for IP network data transmission.
This operation manual details main features of SMG-2 and SMG-4 digital gateways. The document
contains technical specifications of the gateway and its components. Also, it provides an overview of operation
and maintenance software-based procedures.
