Mitel Networks 3100 ICP Controller provides the voice, data, signalling, central processing and communications resources for the system.

The Mitel Networks 3100 ICP Controller contains the following:-

• System Control Card;
• Compact Flash Module;
• 8-port Layer 2 switch (the ports are dual speed 10/100 Mbits and provide power to the Mitel Networks IP Phones);
• Router/WAN Ethernet port;
• Two full duplex asynchronous serial ports;
• Four analogue line (LS/CLASS) ports;
• Music on Hold input jack;
• Two ONS/analogue extension ports;
• Dual Modem Card;
• Power fail transfer circuit from the first LS/CLASS port to the first ONS/analogue device port.

There are three slots that are used for optional modules that provide additional analogue line (LS/CLASS) ports and ONS/analogue extension ports.

The Mitel Networks 3100 ICP Controller is designed for free-standing installation on a desktop, for mounting in a 19" rack or hanging on a wall. A plastic fascia is fitted to the front panel, and both the fascia and panel have openings giving access to the peripheral interfaces on the control card and the optional line and extension modules. The rear panel includes the power input connector and has an opening for the connector to the Mitel Networks 3100 ICP Expansion. The top cover can be removed giving access to the unit for maintenance, adding optional modules and adding an Uplink card to provide connection to the Mitel Networks 3100 ICP Expansion.

Mitel Networks 3100 ICP Expansion provides additional 10/100 switched Ethernet ports. The ports supply power to the Mitel Networks IP Phones. Two versions of the Expansion are available, providing eight or 16 ports, respectively.

The two versions of the Expansion are physically identical in their outside dimensions. The Expansion is suitable for free-standing installation on a desktop, mounting in a rack or hanging on a wall. The unit can be stacked beneath the Controller using plastic stacking feet. The Expansion is stacked beneath the Controller for easy access for maintenance purposes. A Y-power cord is supplied with the Mitel Network 3100 ICP Expansion so that only one power outlet is required for both the Mitel Networks 3100 ICP Expansion and Controller.

A plastic fascia is fitted to the front panel; both the fascia and front panel have openings for one (eight port version) or two (16 port version), 10/100 switched Ethernet ports. The rear panel has an opening for the power connector and the connector from the uplink module in the Controller.

 

The optional modules increase the number of lines and analogue devices that can be supported by the 3100 ICP. The modules available are:-

• 2-port ONS module;
• 4-port ONS module;
• 4-port LS/CLASS module.

The System control card provides three identical mounting positions, each of which can be used for any of the module types.

ONS Module

The ONS module provides an interface between Mitel Networks 3100 ICP and ONS/analogue devices. The ONS modules available are:

• 2-port;
• 4-port.

The ports on the ONS module provide the same features and services as the ONS ports on the Controller control card, and are listed in the Hardware section of the Technical Manual.

LS/CLASS Module

The LS/CLASS module provides an interface between Mitel Networks 3100 ICP and LS/CLASS analogue exchange lines. Mitel Networks 3100 ICP supports up to 8 LS/CLASS circuits.

 

IP routing determines the best route for getting an IP packet to its destination. To determine this route, the router contains tables of information about destinations, including networks, sub-networks (or subnets) and hosts, and how best to reach these destinations.

The purpose of IP routing is to:-

• establish connections between Mitel Networks 3100 ICP and devices on multiple LAN and WAN networks;
• transfer IP packets between Mitel Networks 3100 ICP and these network devices;
• ensure that Voice over IP (VoIP) packets are given priority over data packets and receive an adequate QoS (Quality of Service).

The following networking protocols and technologies are used in Mitel Networks 3100 ICP:-

• Point-to-Point Protocol (PPP);
• File Transfer Protocol (FTP) and Trivial File Transfer Protocol (TFTP).

The Mitel Networks 3100 ICP DHCP server functionality can be used to assign IP addresses to other IP devices on the locally attached networks and may be turned off if the Mitel Networks 3100 ICP is integrated into an existing LAN with a DHCP server. The DHCP client may be used to obtain an IP address to use as its host IP on a connected network. NAT (Network Address Translation) may be used on remotely attached networks. Remote WAN locations are supported via xDSL, frame relay or dial-up PPP connections. The Mitel Networks 3100 ICP router is capable of supporting up to five interfaces simultaneously.

SonicWALL Internet Security

The SonicWALL Internet Security appliance provides a secure barrier between private LANs and the public Internet. When used with the Mitel Networks 3100 ICP it enhances security measures and protects the local network through its firewall and Virtual Private Networking (VPN) functionality.

For specific information regarding SonicWALL products, please refer to the appropriate technical documentation.
