Select function from above or <RET> for previous menu:

Information for the new device may be configured in any order. You have control over how much information is specified for each device, and the order in which it is entered.

We will begin by specifying the type of device. This device is an ISDN device, so we will press 1 for ISDN from the Device Table Menu.

The ISDN Menu will then be displayed with the preconfigured default values as shown below:

Device ISDN Menu: (Device = "SITE2")

1)

ISDN Line Protocol

"PPP (Point to Point Protocol)"

2)

Base Data Rate

"64000 bps"

3)

The ISDN Line Protocol default configuration value of “PPP” is what SITE2 uses, so no changes are required for this parameter.

The last three items on the ISDN Menu (initial data rate, maximum data rate, and first dial out number) must be configured for each PPP device SITE1 wants to be able to call.

The default values of the Base Data Rate and the initial data rate are acceptable. No changes are required for these parameters.

We want to change the default maximum data rate for this example. Press 4 to change the maximum data rate. The maximum data rate is used to limit the total number of channels that can be committed to a single logical connection. This sets an upper boundary for line and capacity utilization. This upper boundary allows you to keep one remote device from crowding out other devices and using an unfair share of available resources. This parameter is enforced on inbound and outbound calls. SITE1 will not accept or make a call when the added bandwidth will exceed the configured maximum. The value is configured as a number from 2,400 to 2,048,000. You may configure any value in this range. For example, if you have configured the base data rate at 64 Kbps, and the maximum data rate at 512,000, SITE1 would use a maximum of eight calls (connections) running in parallel to open up bandwidth quickly (512,000 / 64,000 = 8). The value need not be a multiple of the base data rate. For this example, enter 384,000 for the maximum data rate.
