CONFIGURING PRIORITY USERS
1. On the Functions menu, select CyberSWITCH, or click on the toolbar. The CyberSWITCH
List dialog appears.
2. Select a CyberSWITCH that which you want to configure Priority Users. The Remote Access
Switches dialog appears.
Note: Configuring Priority Users for a CyberSWITCH can only be done in the Update mode.
3. Select the Priority Users tab.
4. Click Add for either ISDN or Digital Modem, depending upon the type of user you would like
to add to the priority user list.
Note: Users must be previously configured on the SQL database before they can be
designated as priority users. Refer to the Configuring Users chapter for more
information. The list of users displayed includes only those that have been configured
as ISDN or Modem users, respectively, and that are in the same group as the
CyberSWITCH.
5. Select the user that you want to be a Priority User and click OK.
6. Click Update to write the new information to the database.
7. Click Close.
POOLING
The IP Address Pool feature allows you to configure a list of IP addresses that can be dynamically
assigned to remote IP devices as they connect to the CyberSWITCH. This occurs when a remote IP
device calls in to the CyberSWITCH and has no IP address, and requests to have one assigned. With
this capability, you no longer need to assign permanent IP addresses to all possible remote IP
devices, but rather only as many IP addresses as the number of possible ISDN connections. If
multiple connections are used, you would not need as many IP addresses as the number of possible
ISDN connections. This can result in a reduction of the number of IP addresses required for remote
IP users.
When a PPP connection is established to a Remote Access Switch, the Remote Access Switch and
the remote device exchange their IP addresses during the IPCP (IP Control Protocol) phase. If the
remote device does not know its own IP address, SFVRA Connection Manager will assign a proper
IP address to it. A proper IP address can be a permanent IP address configured for the remote
device in the user table, or it can be one of the IP addresses configured in the IP Address Pool. If an
IP address from the address pool is used, it will be returned to the pool when the connection is
terminated. This allows the IP address to be reused for other remote IP devices.
Remote Access Switches supporting the IP Pool feature form a hunt group for the users. We suggest
restricting bandwidth to a single B-channel for remote sites. Each CyberSWITCH within the hunt
group should be configured with the same CyberSWITCH name, password, secret, and IP WAN
interfaces, so the remote user dialing in is not aware of the CyberSWITCH on which the connection
was established. This feature is optional.
