10.3.2 Using a Dedicated T1/PRI ISP Link
This section shows an example of a dedicated WAN PPP link to an Internet Service Provider (ISP) over a set of T1 or T1
PRI line channels. The ISP must support this mode of connection and will need to provide details of the required settings.
If multiple channels are to be used, then the ISP must support Multilink PPP.
1.Create a New WAN Service
A service is used to define connection settings such as name, password, bandwidth, etc.
1.Select Service to display the existing services.
2.Click on and select WAN Service.
3.Select the Service tab.
1.In the Name field enter an appropriate name, such as “Internet”. Note that the system will also
automatically create User record and a RAS record with the same name.
2.Enter the Account Name, Password and Telephone Number details provided by the ISP.
3.For the Firewall Profile select the firewall created previously.
4.Click the Bandwidth tab.
1.Set the Maximum No. of Channels to the maximum number of channels that the service should use. In this
example, 12 channels were used.
2.Leave all the other records at their default values.
3.If the ISP has allocated IP address details these are entered through the IP tab. If the IP Address and IP Mask
define a different domain from the system LAN, then NAT is automatically applied.
5.Click the IP tab.
1.In the IP Address field enter the IP address specified by the ISP.
2.In the IP Mask field enter the IP Mask specified by the ISP.
3.The settings shown are typical. The actual settings must match those required by the ISP. For example, if
Cisco routers are being used then IPHC needs to be ticked.
6.Click the PPP tab.
1.Ensure that the following options are selected. Leave all other options at their default settings.
· Multilink.
· Compression Mode: Disable.
· Callback Mode: Disable.
· Access Mode: Digital64
7.Click OK.
2.Create the Virtual WAN Port
In this stage, a WAN port is defined that actually uses T1 or T1 ISDN trunk channels.
1.Select WAN Port to display existing ports.
2.Click on and select WAN Port.
3.In the Name field, enter either LINEx.y where:
· LINE must be in uppercase.
· x is the line number. For a trunk card in Slot A, this will be 1. For a trunk card in Slot B, this will be 5.
· y is the lowest numbered channel number to be used by the WAN link minus 1. For example, if the lowest
channel to be used is channel 1 then y = 1 - 1 = 0.
4.In the Speed field, enter the total combined speed of the maximum number of channels sets in the Service. In
this example, 12 channels x 64000 bits = 76800.
5.Set the Mode to SyncPPP.
6.In the RAS Name field, select the name used for the Service.
7.Click OK.
