Introduction - Teldat Atlas 250 Installation Manual

1. Introduction

The Atlas250 is a device developed by TELDAT designed to adapt to most habitual teleprocess
networks scenarios: corporate, SME and personal environments (SOHO).
Through its WAN-LAN connections, this device provides router IP functions, supporting OSPF and
other dynamic routing protocols. The Atlas250 also presents a wide variety of connection possibilities
in SNA environments, from LLC2 and SDLC to QLLC conversion, that allow direct interconnection
of an Atlas250 to a local network without requiring a communication card in the server, and includes
SNA transport over IP networks through Data Link Switching (DLSw). This option permits the
transport network architecture to be standardized for TCP/IP.
As regards interfaces with public or private Wide Area Network (WAN), the Atlas250 permits access
to the Integrated Services Digital Network (ISDN) through a basic access through D and/or B channel.
In addition to the direct X.25 option, the possibility of FRAME-RELAY or PPP connections up to
speeds of 2 Mbps has been added.
The basic configuration consists of two LAN interfaces and three serial WAN interfaces and an ISDN
access. This can be amplified through the insertion of cards, both in Teldat format as well as in PMC
format (PCI Mezzanine Card), which can support encryption, voice over IP (VoIP), xDSL, etc.
