(cell site) by putting the phone in service and having the operator

originate a call from the handset. Specifically, this test performs the

following:

1. The test system simulates a control channel.

2. The operator is instructed to dial 123 123 4567 after the MSUT has

service. (Service is indicated by the NO SERVICE light going off or

the SERVICE light illuminating on the MSUT.)

3. Performs 3 of 5 majority voting on the Reverse Control Message

4. Performs BCH error detection and correction of the Reverse Control

Message, Wideband data

5. Tests each section of the origination message, bit by bit

6. Sends an Initial-Voice-Channel-Designation order to the MSUT

directing it to tune to a voice channel obtained from the Channel

Information table.

7. Makes a power measurement on the initial voice channel to verify

that the voice channel was obtained. The power level measurement

result is not displayed in this test.

It is not necessary to register the phone with the test set by running

TEST_01 - CPA Registration before running this test. TEST_21 - CPA

Origination will read the MSUT’s Mobile Identification Number (MIN)

and the test set will retain it for use in performing other tests.

If the channel number from the table has an L, M, or U suffix, the

phone will be directed to a narrow voice channel. If the channel number

has no suffix, the phone will be directed to a wide voice channel.
