Transaction Language 1 (TL1)

INTRODUCTION

Transaction Language 1 (TL1) is a BELLCORE standard used in the

input and output messages that pass between Operations Systems

(OS) and Network Elements (NE) in telecommunication networks.

It was developed to standardize equipment surveillance and

memory administration, and to test with a common format.

This release of TL1 primarily supports the interactive and

autonomous retrieval of system events as part of a valid TL1

session.

OVERVIEW

TL1 is an ASCII based language that supports both command-

response and autonomous (NE) message generation. Commonly,

TL1 is used over a X.25 packet network but is completely

independent of any physical layer protocols. For the MX2800, TL1

is implemented as a TELNET session or “Raw TCP” session

running over either Ethernet or PPP.

In order to initiate a TL1 session successfully, the unit must be

properly configured for an Ethernet (LAN) or PPP connection. A

valid IP address, gateway address, and a valid subnet mask are

required (see Chapter 3. Configuration - System Management on

page 3-13.) User authentication is also required. An account must

be setup before initiating a TL1 session.
