Mitel Networks 3800 IP Trunking Gateway

MSDN IP trunking functionality is available on an SX-2000 system by connecting a Mitel

Networks 3800 IP Trunking Gateway. The Mitel Networks 3800 IP GW transports voice over

IP networks using IP trunks. The IP trunks behave the same as MSDN trunks, but use the

existing intranet to transport both voice and signaling data. The Mitel Networks 3800 IP GW

connects to an SX-2000 system via fiber (software upgrades are not necessary on the SX-2000

system) and mimics a CEPT Formatter card running MSDN.

Voice connections between the two systems are transported over fiber to the Application Fiber

Control (AFC) card. The AFC card switches the voice channel onto the MVIP stream allocated

to the IP Trunk card. The IP Trunk card packetizes and streams the voice to the appropriate

network node. An MVIP cable must be attached to both cards.

The Mitel Networks 3800 IP GW is offered as a stand-alone TS1400 PC server for connection

to the SX-2000 system. It contains the following cards:

• Application Fiber Control (AFC) Card - for fiber connectivity between the gateway and

the FIM in the main control cabinet of an SX-2000 system. Must be inserted an ISA slot

located below the main CPU board.

• IP Trunk Card - converts TDM voice to IP voice packets and vice versa. This card can

be purchased in a 30 or 60 channel variant. Must be inserted in a PCI slot above the main

CPU board.

Programming

• Program a DSU cabinet in the Cabinet Assignment form.

• Program a Universal E1 (CEPT Formatter II) card in the System Configuration form.

• Program a link descriptor using the DPNSS protocol in the Link Descriptor Assignment

form.

• Program the Date and Time on each PBX in the network.

• Assign the link descriptor to the Universal E1 (Cept Formatter) card in the Digital Link

Assignment form.

• Program the MSDN trunks (IP trunks) for the Universal E1 (Cept Formatter) card in the

Trunk Assignment form.

• Create a trunk group and assign all IP trunks to it in the Trunk Group Assignment form.

• Define the numbering plan for all Mitel Networks 3800 IP GWs using the Automatic Route

Selection Assignment form. All programmed routes intending to use IP trunks must select

the same trunk group and pass the leading digits which define the route or the Cluster

Element ID (CEID).

• Specify the number of digits to absorb for the trunk service numbers specified for the

MSDN trunks in the Trunk Service Assignment form.
