This is covered in the "MAX 6.0.0 Release Notes".

See the "RADIUS features" section item "Configuring Data Over Voice Bearer
Service (DOVBS) in RADIUS".

Configuring Data Over Voice Bearer Service (DOVBS) in RADIUS

  In previous releases, you were limited to specifying four phone numbers
  that the Ascend unit would handle as data calls, even if they came in as
  voice calls.  These numbers are known as DNIS (Dialed Number Information
  Service) numbers. For some purposes, the limitation of four numbers is
  restrictive. Therefore, in this release, you can use RADIUS to specify
  up to 100 phone numbers.
  
Configuring DNIS numbers in RADIUS
  
  This feature  addresses those locations in North America that charge
  significantly higher rates for digital bearer service than voice bearer
  service. In addition, this feature can be used by larger ISPs that resell
  services to smaller ISPs, identifying them by DNIS number. To configure
  DNIS numbers in RADIUS, follow these steps:
  
  1    Create the first line of a pseudo-user entry using the User-Name
       and Password attributes.  You create a pseudo-user to store information
       that the Ascend unit can query-in this case, in order to store DNIS
       numbers. You can configure pseudo-users for both global and Ascend
       unit-specific configuration control of DNIS numbers. The Ascend unit
       adds the unit-specific information in addition to the global information.
       For a unit-specific DNIS configuration, specify the first line of
       a pseudo-user entry in this format:
         dovbs-<unit_name>-<num> Password="ascend"
       For a global DNIS configuration, specify the first line of a pseudo-user
       entry in this format:
         dovbs-<num> Password="ascend"
       <unit_name> is the system name of the Ascend unit-that is, the name
       specified by the Name parameter in the System Profile. <num> is a
       number in a sequential series, starting at 1.
  
  2    For each pseudo-user entry, specify one or more DNIS numbers using
       the Client-Port-DNIS attribute.
       Specify each DNIS number in this format:
         Client-Port-DNIS="<DNIS number>"
       Client-Port-DNIS specifies the called-party number, indicating the
       phone number dialed by the user to connect to the Ascend unit.
       You can specify up to 100 DNIS numbers; if you specify more than
       100, the remaining numbers are ignored.
  
  Consider this example:
  Five small ISPs connect to a larger ISP using DOVBS with the following
  numbers:
    *    5105551111
    *    5105552222
    *    5105553333
    *    5105554444
    *    5105555555
  The pseudo-user profile for an Ascend unit named "Toronto" looks like
  this one:
  
    dovbs-Toronto-1 Password = "ascend"
      Client-Port-DNIS = "5105551111"
      Client-Port-DNIS = "5105552222"
      Client-Port-DNIS = "5105553333"
      Client-Port-DNIS = "5105554444"
      Client-Port-DNIS = "5105555555"
  
How the Ascend unit learns about DNIS entries
  
  When you have properly configured the pseudo-user profile, RADIUS loads
  DNIS numbers whenever you power on or reset the Ascend unit,  when you
  select the Upd Rem Cfg command from the Sys Diag menu, or when you use
  an update command in SNMP. RADIUS loads the numbers in this way:
  
  1    RADIUS looks for entries having the format dovbs-<unit_name>-1,
       where <unit_name> is the system name. 
  
  2    If at least one entry exists, RADIUS loads all existing entries
       with the format  dovbs-<unit_name>-<num>.
       The variable <num> is a number in a sequential series, starting
       with 1.
  
  3    The Ascend unit queries dovbs-<unit_name>-1, then dovbs-<unit_name>-2,
       and so on, until it receives an authentication reject from RADIUS. 
  
  4    Once the host-specific numbers are loaded, RADIUS loads the global
       configuration entries; these configurations have the format dovbs-<num>.
  
  5    The Ascend unit queries dovbs-1, then dovbs-2, and so on, until
       it receives an authentication reject from RADIUS. 
  
  6    The Ascend unit checks the DNIS number of each incoming call against
       the phone numbers it has loaded.
