Using Shorthold Mode 73

However, if the other side wishes to be the first to send a data packet, it will have to ‘notify’

the side that initiated the shorthold. This means that it calls without establishing a

connection. The side controlling the shorthold will then call back and establish the

connection.

Exclusive allocation of charges

When Diva Server for Windows NT shorthold is appropriately configured, charges are

allocated exclusively either to the calling computer (see … Charged to the RAS client

below) or to the called computer (see … Charged to the RAS server

on page 74).

Note: In countries where a dial attempt is subject to a charge even when a connection

is not established (e.g. Switzerland), charge allocation does not function exclusively. In

this case the side that notifies the other after a shorthold and therefore requests the

establishment of a connection will pay the charges for the notification.

… Charged to the RAS client

The RAS client establishes the connection, initiates the shorthold and reconnects the

subsequent calls. In this way, the charges are allocated to the RAS client only.

Client configuration (see Shorthold Settings on page 31):

• Shorthold Mode = selected

• Shorthold Time must be set to a value not equal to zero. It should be set to the charge

period or a multiple to enable the most efficient possible usage of already paid charge

periods.

Server configuration (see Shorthold Settings on page 31):

• Shorthold Mode = selected

• Shorthold Time = 0

• No different MSNs should be assigned to the RAS ports. This will ensure that not just

one server port will be available for the initial establishment of a connection on the client

side (see Phone numbers/extensions and subaddresses

on page 28).
