AMR Setup
Last updated: January 15, 2009
AMR Source
The following AMR Sources are available in the test set:
-
Echo
While in
ECHO
, the test set loops the transport blocks arriving from the UE on the uplink back down to the UE (unaltered) on the downlink. There is a fixed voice echo delay of 0.5 seconds.
-
Real-Time Vocoder
-
External 8960
While in External 8960, the traffic data is routed from one UE through an 8960, over the LAN interface to a second 8960 and then to the second UE. The data flow is bidirectional and so the behaviour at each UE is like that of a real speech call.
GPIB command:
CALL:SERVice:AMR:SOURce
This parameter can only be set when call/data status is idle.
AMR Radio Access Bearer
The
AMR Radio Access Bearer
can be set to:
-
12.2k Voice (3GPP TS 34.108 s6.10.2.4.1.4)
-
10.2k Voice(3GPP TS 34.108 s6.10.2.4.1.5)
-
7.95k Voice (3GPP TS 34.108 s6.10.2.4.1.6)
-

This parameter can only be set when call/data status is idle. Note: "k" refers to kbps.
