4.2 Sample Scenarios with IBM 2212 and IBM 9783

This section shows some sample scenarios that have been tested and some

scenarios that are currently implemented in some customer locations. These

scenarios will be useful when installing and configuring IBM 2212 Access Utility

and IBM 9783 for a voice over frame relay network.

4.2.1 Sample Scenario of IBM 2212 within the Branch

The first scenario shows how call routing is done within a branch, that is, within a

single 2212 Access Utility with two voice ports.

Figure 45. Sample Scenario within the Branch

The aim of this sample configuration is to provide a very simple environment to

begin configuring the voice cards on the IBM 2212 Router. The above 2212 has

one FXS adapter with two ports on it. Configure the 2212 to allow the two phones

connected to two ports of FXS adapter to call one another. For this sample

configuration, we will not bother with configuring the frame relay interfaces, etc.

4.2.1.1 The Hardware Used in This Sample Configuration

• One 2212 with AIS V3.3 and higher

• One FXS analog adapter card

• Two analog telephones

• Two RJ11 cables

4.2.1.2 Estimated Time

It takes about 30 minutes to perform this sample configuration.

4.2.1.3 The 2212 Sample Voice Configuration Worksheets

We will use the following blank sheets to design 2212 voice configuration. Some

values are already filled in as default parameters.

• The dial digit matching rule lets you specify the range of acceptable digits at

each position in a dial digit sequence. You can specify multi-digit wildcards as

well as a sequence that causes an immediate connection during an “off-hook”

condition (in red).You can define a pool of up to 64 rules and specify a dial

digit rule in each call processing rule.
