20/34 Getting Started with the HNS 9201
You can make and receive voice calls by connecting a telephone handset to the terminal, as shown
below:
You can use two types of phone handset:
•
An ISDN handset.
•
A 2-wire analog handset with an ISDN terminal adaptor.
Before you can use your handset for voice services, you must program its MSN (Mobile Subscriber
Number) to 1 for a 4kbps call or 2 for a 3.1kHz speech call. This identifies the handset and call
quality required to the terminal.
NOTE: Voice calls are charged by call duration, and a 3.1kHz voice call is charged at a
higher rate than a 4kbps voice call. Refer to your Service Provider for details on
call charges.
