IPedge General Description 01/12
When using home type xDSL or cable connections, only one or two IP telephones may be
connected because of xDSL and cable bandwidth limitations. Broadband is required when
installing two or more phones at a remote site.
An Internet configuration could use the following connections:
•
No VPN, and thus, no security
•
Third party VPN software residing on DHCP gateway server. To connect IP telephones over the
Internet, using third party or Microsoft VPN software residing on a DHCP gateway server, see
•
ATM (IP over ATM virtualization by VC/VP)
•
Broadband Ethernet virtualization by Virtual LAN (VLAN)
•
IP-VPN (IP-VPN based on Multi-protocol Label Switching (MPLS)
•
Private line connection
For an access line to link the user’s location with the access point of the carrier or provider, using a
private line, broadband line (xDSL, CATV), or fiber optics is recommended.
The IPT Anywhere feature enables remote IP telephone users working in branch offices or home
offices to make full use of the extension features of the IP
edge
. The diagram below shows IPT
Anywhere connections using the optional VPN connection.
