2 The Contivity Extranet 4500 Switch
The Nortel Networks Contivity Extranet Switch 4500 provides a scalable, secure, manageable
remote access server that meets FIPS 140-1 level 2 requirements. This section will describe
the general features and functionality provided by the Contivity Extranet Switch. Section 3 will
provide further details on how the Contivity Switch addresses FIPS 140-1 requirements.
2.1 Cryptographic Module
The Contivity Extranet Switch combines remote access protocols, security, authentication,
authorization, and encryption technologies into a single solution.

The Switch can support up to 5,000 simultaneous user sessions, allowing each user to exercise
a variety of secure connections and services. The Switch supports a number of secure
network-layer and data-link-layer protocols including Internet Protocol Security (IPSec), Point-
to-Point Tunneling Protocol (PPTP), Layer Two Tunneling Protocol (L2TP), and Layer Two
Forwarding (L2F). The architecture for the Switch is user-centric, where an individual user or
group of users can be associated with a set of attributes that provide custom access to the
Extranet. In effect, you can create a personal Extranet based on the special needs of a user or
group.
2.2 Module Interfaces
The interfaces for the Switch are located on the rear panel as shown in Figure 2.
