Together, the preceding factors allow you to configure more IP endpoints than the number of IP
resources available in a system. If all IP resources are in use, subsequent demands for IP
resources are placed in a Camp On state until IP resources become available.
Depending on the configuration of reserved IP resources, a few scenarios may produce an
unavailable IP resource condition. When system configuration results in an unavailable
resource, a warning appears on display endpoints, and the user hears a beep every 5 seconds.
To review the scenarios that may generate an unavailable IP resource error, refer to the Inter-
Tel 5000 Features and Programming Guide (part no. 580.8006).
IP Device Resource Manager
The IP Device Resource Manager maintains all IP resource requests in the system along with
all allocated IP resources in the system. It provides useful diagnostic data to determine what
types of calls are going on in the system and how long calls have been both camped-on or on
an active call. For details, refer to the Inter-Tel 5000 Features and Programming Guide (part no.
580.8006).
Node IP Connection Group
The Node IP Connection Group corresponds to an IP network connection between a remote
node and the local node.
Networking
Two or more Mitel advanced communication platforms can be connected with T1/E1/PRI
network spans to form a network. To the user, the network appears as one integrated system.
With few exceptions, the user can perform all of the functions across the network that can be
performed within a single system, or node. For networking specifications and details, see
Private Networking.
In a Mitel IP private network environment, IP endpoints can be programmed to traverse, or
bypass, the Network Address Translation (NAT) tables. A Mitel 5000 platform may be placed
behind the firewall using a static NAT assignment.
For details about networking options, see Network IP Topology. For procedural instructions to
implement near-end NAT traversal for IP endpoints, refer to the Inter-Tel 5000 Features and
Programming Guide (part no. 580.8006) and “Configuring Near-End NAT Traversal for IP
Endpoints” on page B-13.
NOTE
To effectively oversubscribe an IP-dominant system, the Resource Reservation
feature must be used sparingly to avoid depleting the system pool of available IP
resources. For programming details, refer to the Inter-Tel 5000 Features and
Programming Guide (part no. 580.8006).
