Chapter 9 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 STS-1, TL1 is implemented as a Telnet session running over either Ethernet or PPP.

Currently, up to eight simultaneous TL1 Telnet connections can be active. To manually bring up a TL1 Telnet connection, a Telnet client is used to request a connection on (TCP) port 3116. A successful connection will require that the MX2800 STS-1 be properly configured to operate via the LAN or modem. For example, in the LAN case, the MX2800 STS-1 must have the LAN
