Workgroup Remote Access Switch 69IP ROUTING N ETWORK WITH PPP DEVICESConfigure SITE1Information for the new device may be configured in any order. You have control over how muchinformation 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 forISDN from the Device Table Menu.The ISDN Menu will then be displayed with the preconfigured default values as shown below:The ISDN Line Protocol default configuration value of “PPP” is what SITE2 uses, so no changes arerequired for this parameter.The last three items on the ISDN Menu (initial data rate, maximum data rate, and first dial outnumber) 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 arerequired for these parameters.We want to change the default maximum data rate for this example. Press 4 to change themaximum data rate. The maximum data rate is used to limit the total number of channels that canbe committed to a single logical connection. This sets an upper boundary for line and capacityutilization. This upper boundary allows you to keep one remote device from crowding out otherdevices and using an unfair share of available resources. This parameter is enforced on inboundand outbound calls. SITE1 will not accept or make a call when the added bandwidth will exceedthe configured maximum. The value is configured as a number from 2,400 to 2,048,000. You mayconfigure 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 amultiple of the base data rate. For this example, enter 384,000 for the maximum data rate.Device Table Menu: (Device = "SITE2")1) ISDN2) Frame Relay3) X.254) Authentication5) IP6) IPX7) AppleTalk8) Bridging9) CompressionSelect function from above or for previous menu:Device ISDN Menu: (Device = "SITE2")1) ISDN Line Protocol "PPP (Point to Point Protocol)"2) Base Data Rate "64000 bps"3) Initial Data Rate "64000 bps"4) Maximum Data Rate "128000 bps"5) Dial Out Phone Number(s) ""6) Subaddress ""7) Profile Name "Default_Profile"8) H0 Call Support DISABLEDSelect function from above or for previous menu?
