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

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

The base data rate, 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 out to. The default values of the base data rate and the initial data rate are acceptable. No changes are required for these parameters.

We do want to change the default maximum data rate for this example. 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.

We also need to enter a phone number for each remote device that will be dialed. This number includes any prefix digits, area codes, or extensions as required to dial the destination device. It is possible to specify more than one phone number for the remote device. For this example, we will only be entering one phone number, 913135553232, which is the phone number for SITE2.

After all of the ISDN configuration has been completed, the ISDN Configuration Menu will be displayed as shown below:
