Programming Example
OUTPUT 714;"CALL:TCHANNEL:TSLOT 5" !Sets time slot number.
Sets traffic channel loopback state and type for the MS.
The loopback type must be set before a Fast Bit Error or a Bit Error
measurement will function.
The test set will automatically set the correct loopback type if the
signalling loopback control is set to on, after the measurement the test
set will automatically set the loopback to off. See
"SETup:BERRor:SLControl" on page 389

range:
• OFF - Sets the TCH Loop state for the MS to OFF. The loop back is
open.
• A- Sets the TCH Loop state for the MS to type A. Full-rate speech
TCH loopback with signaling of erased frames, (residual).
• B- Sets the TCH Loop state for the MS to type B. Full-rate speech
TCH loopback without signalling of erased frames, (non-residual).
• C - Sets the TCH Loop state for the MS to type C. TCH burst by burst
loopback.
OFF
Sets the Timeslot number used for downlink and uplink Traffic Channel.
