3.4.2 Call waiting 

As indicated in the previous section the user can enable the 
Call Waiting Notification in order to receive incoming voice 
calls during an MPDS session. The enabling can optionally 
be restricted to specific phone numbers.  

The 4-wire and 2-wires interfaces can be configured for 
usage for the Call Waiting Notification. When the 
notification arrives, the user is notified by a special ringing 
tone and a message is shown in the display if the 4-wire 
handset is selected for the service. 

In case of an incoming call during an MPDS session with 
the Call Waiting Notification enabled, the user has three 
options: 

1.  The user can reject the pre-emption of the MPDS 

connection by pressing “*” or “Exit” on the 4-wire 
handset (if enabled) or by taking an enabled 2-wire 
phone off hook, pressing “*” and placing the phone on 
hook again. The ringing stops on all handsets that are 
configured for the service. 

2.  The user can accept the pre-emption of the MPDS 

connection by pressing “OK” or “#” on the 4-wire 
handset (if enabled) or by taking an enabled 2-wire 
phone off hook, pressing “#” and placing the phone on 
hook again. The MPDS session is now deregistered and 
the call gets through after a short while. The phone(s) 
to which the call is routed starts ringing and the call 
can be answered. Note that the call can be answered 
on another interface than the interface that was used 
to accept the call – e.g. a fax will normally only be
