AT-VP504E FXS 21
Initial Provisioning
Sequence
When powering the AT-VP504E FXS for the first time, it needs to be
configured before it can support calls. This process is known as
provisioning . There are several components involved in provisioning.
This sequence assumes that you have installed the AT-VP504E FXS
hardware and connected it to a compatible Ethernet interface that
supplies TCP/IP network access (e.g. router, switch, hub or computer).
Initial provisioning sequence:
1. When the AT-VP504E FXS boots, it broadcasts a message
requesting DHCP services.
2. The DHCP server responds with a set of IP addresses and
network parameters, one of which is the AT-VP504E FXS IP
address.
The following are some of the network parameters assigned
via DHCP:
• AT-VP504E FXS IP address
• Subnet Mask
• Default Router IP address
• Primary DNS IP address
• Secondary DNS IP address
• Unit Manager IP address
• Unit Manager IP port number
3. The AT-VP504E FXS uses the IP address of the Unit
Manager to request its configuration.
4. The Unit Manager configures the AT-VP504E FXS.
Note: The AT-VP504E FXS requests its configuration only on the first
boot.
