Task
Description
Step 7 (optional) 
This step is optional and is only required if two 
ISDN bearer channels are required. Proceed 
to the next step if a single bearer channel is to 
be used. Apply the parameter to the IP401 
Parameter 
IPNC
IP401
Service /Bandwidth
• Max Number
Channel
<blank> 2
Service /Bandwidth
• Extra BW Threshold
<blank>
20*
 
This optional configuration allows the IP401 to dial a 
second ISDN bearer channel when bandwidth 
utilisation exceeds 25% on the first channel (100% = 
64Kbps). 
 
 
 
*Optional: 
With a value of 20 the second bearer channel is 
established when a send voice call is made. Increase 
or decease this value relative to requirements. 
Step 8 (optional) 
This step is optional and is only required if the 
NAT functionality is required. Proceed to the 
next step if NAT is not required. 
 
Apply the following configuration to the IPNC 
 
System/LAN1 
• NAT = selected
 
With this option selected the IPNC will NAT source IP 
addresses from the Homeworker’s network to the 
LAN1 IP address of the IPNC. This feature is most 
useful when the Homeworker requires Internet access 
via the Corporate network and Internet compliant IP 
addresses are in short supply. 
Because the NAT process is only applied to IP 
packets leaving through the LAN1 interface, this 
configuration is suitable for VoIP. It would not be 
permissible to enable NAT on the IP401as this would 
effect the suitability of the application to support VoIP. 
 
Step 9 
Add an IP route entry to support the 
connection. 
IPNC 
• IP Address = 192.168.100.0 
• IP Mask = 255.255.255.0 
• Gateway = <blank> 
• Destination = IP401 
IP401
• IP Address = 135.64.180.0 
• IP Mask = 255.255.255.0 
• Gateway = <Blank> 
• Destination = IPNC
 
A routing entry must be added to allow access 
between the two networks. 
 
 
 
 
 
 
Note: You can optionally configure the System/DNS 
tab on the IP401 for DNS, WINS, WINS 
Scope. 
Step 10 
Submit and test Configuration 
 
 
Use the repeat Ping option (-t) to a device on the 
remote location and observe the Monitor Application. 
While the Ping is maintained, select Call Events and 
ensure that the IP401 dials the number configured in 
Step 6. 
If the IP401 dials, connects and then immediately 
disconnects but the Pings are unsuccessful, use the 
Monitor application and select PPP to check LCP 
TX/RX and Security TX/RX. This will show whether the 
call is cleared as result of a bad password and/or 
incompatible PPP parameters.
