H.323 VoIP Gateway Voice and Convergence Features
Page 1-16
The AVNDS handle inbound/outbound calls routing to/from the VoIP network and local 
ports. AVNDS are also used to set up calls and translate IP addresses to telephone numbers, 
and can be used with, or in lieu of, H.323 VoIP gatekeepers.
VoIP configuration boot files and profiles simplify VoIP configuration of Alcatel’s H.323 VoIP 
gateways (VoIP daughtercards) by using sets of pre-configured parameters that can be 
assigned to the various manageable components. Various configuration elements, e.g., 
profiles, have a user-defined name associated with it. VoIP daughtercard configurations are 
stored in the switch.
Destinations which consist of remote network and local calling gateways, including H.323 
gatekeepers, allow Network Administrators to configure a destination IP address and its 
specific protocol. Local channel destinations are considered subdestinations. Destinations, 
which are appended to hunt methods, are configured at the daughtercard level.
Phone groups are used to indicate what telephone numbers are available. They also define 
digits to be stripped and forwarded. Phone groups are configured at the daughtercard level.
Voice numbering plans use hunt methods to arrange telephone lines so that when calls come 
into the network they will ring in a certain order. For example, to use PSTN fallback, all 
phone groups must be set up with the last group element indicating the local destination or 
gateway to fall back on when a call cannot be placed over the VoIP network.
Hunt methods in voice numbering plans are configured at the daughtercard level. Hunt meth-
ods dictate what to do if the first line tried is busy, i.e., hunt methods are used to track down 
lines in a certain order until an available line is located. Phone line destinations can be 
grouped as desired in user-defined groups, such as by divisions or departments, location, or 
some other meaningful grouping.
For information on setting up and using the AVNDS (Alcatel VoIP Network Dialing Schemes), 
see Chapter 3, “Network Dialing Schemes,” Chapter 4, “Setup and Installation,” and Chapter 5, 
“VoIP Commands.”
Switch Backplane Interface
The switch backplane interface is responsible for the payload packet transport, and VoIP 
daughtercard management message transport between the VoIP daughtercard and the host 
switch. Physically, the interface consists of a 100-pin connector between the VoIP daughter-
card and the motherboard. All functions of the H.323 VoIP gateway are implemented on the 
MPC860 controllers on the daughtercards, the VSX (OSR configurations only) and the switch.
