The Nortel Networks Home Worker solution is built
from a range of IP-capable products. Secure access
into the corporate LAN is provided by the Contivity
suite of VPN switches. Contivity integrates all of the
elements needed to build a high performance,
scalable and secure VPN – routing, firewall,
bandwidth management, encryption,
authentication and data integrity – into one single
platform for secured tunnelling across the Internet.
Home-side telephony is provided by the
Nortel Networks suite of IP telephony solutions,
including the i2050 Soft Client (can be used with a
USB headset), USB phones that connect into the PC
and the i2004 IP phone .
In the office, Enterprises can leverage the evolution
of their existing Meridian-1 PABX solutions by
adding a line-side ITG (Internet Telephony Gateway)
card to enable connectivity of IP clients to the PABX.
