1 Introduction

This document acts as an entry point to the operation and maintenance procedures within virtualized MTAS. It specifies the tasks required to operate the system and references the documents needed to complete those tasks.

The tasks are primarily configuration-oriented, but can be ones that must be executed as actions.

The tasks are grouped into functional areas where appropriate, and presented on a functional level rather than managed object level. This allows mapping of a functional need into a set of documents required to achieve that functional need. This document can therefore be considered a functional or task based index to the virtualized MTAS operation and maintenance documentation suite.

1.1 Prerequisites

This section describes the prerequisites, which must be fulfilled before using the procedures.

1.1.1 Tools

MTAS provides several Northbound Interfaces (NBIs) for operation and maintenance. The included NBIs are as follows:

NETCONF
The NETCONF interface is a machine to machine interface for configuration management of MTAS using the NETCONF protocol. For details, refer to Ericsson NETCONF Interface.
ECLI
The Ericsson Command-Line Interface (ECLI) is a terminal-based command-line interface that allows the user to monitor and manage the MTAS. The ECLI enables the user to interact with the Management Information Base (MIB) through common, generic-purpose commands. For details, refer to Ericsson Command-Line Interface.
SFTP
The SSH File Transfer Protocol (SFTP) is an interface for uploading and downloading files.
SNMP
The Simple Network Management Protocol (SNMP) is an interface for reporting alarms through SNMP notifications.

To access the NBIs, except SNMP, a user must be authenticated and authorized. All user information is stored in a centralized Lightweight Directory Access Protocol (LDAP) server that provides authentication for NBIs. After a user passes the authentication, one or more roles are assigned to this user.

The Role-Based Access Control (RBAC) and the Target-Based Access Control (TBAC) authorization are used to ascertain the user access rights. For details, refer to Security Management for ECLI, NETCONF, and SFTP Users.

1.2 Generic Note for Configuration

To avoid traffic loss in the services provided by the MTAS, it is mandatory to create backup after any change has been made in the MTAS configuration that is meant to be persistent.

2 Services

The MTAS can fulfill several different functional roles in a Multimedia Telephony solution, such as Multimedia Telephony (MMTel) Application Server (AS), Scheduled Conference Application Server (Conf AS), Service Centralization and Continuity Application Server (SCC-AS), and SIP Trunking application server (ST AS).

The following sections describe tasks that are configurable for the offered services per AS.
