Introduction

About Cisco 1100 Terminal Services Gateway

The Cisco 1100 Terminal Services Gateway is a modular terminal gateway that provides asynchronous connections to the console ports for different kinds of network devices such as Cisco third-party network devices, and servers. The Cisco 1100 Terminal Services Gateway offers integrated asynchronous ports, optional switching, and simplified Ethernet. It also supports secure tunnels, such as IPSec, generic routing encapsulation (GRE), and Cisco Dynamic Multipoint VPN, all at scale.

The Cisco 1100 Services Terminal Gateway with the LAN and WAN connections can be configured by means of interface modules and Network Interface Modules (NIMs).

The following features are provided for enterprise and service provider applications:

  • Enterprise Applications

    • High-end branch gateway

    • Centralized Management

    • Zero Touch Provisioning

    • Mulit Tenant

    • Role based access to server and session

    • Regional site aggregation

    • Key server or PfR master controller

    • Device consolidation or "Rack in a Box"

  • Service Provider Applications

    • High-end managed services in Customer-Premises Equipment (CPE)

    • Services consolidation platform

    • Flexible customer edge terminal gateway

The Cisco 1100 Terminal Services Gateway runs Cisco IOS XE software, and uses software components in many separate processes. This modular architecture increases network resiliency, compared to standard Cisco IOS software.
