Data to be displayed is shown above. The resultant signal is then applied to the Analog Mod. Channel Numbers are represented on the display as AA The cellular telephone sends a 1. Acquiring and maintaining synchronization with the Digital Channel 2. The audio samples are then transmitted to the Celulzr.

Once the carrier passes through the VCA, it passes through the mamual final power amplifier which is still internal to U Transmitter control logic – Transmitter keying and frequency band selection.

NAMPS uses sub-audible digital equivalents. The switch orders surrounding cell sites to measure the cellular telephone’s signal strength. This allows proper operation of the ear speaker.

Using the plastic prying tool, ceelular the side tabs away from the assembly to allow it to be easily removed. Voice channels are used for both audio and signaling once a call is established. The peak ST deviation measured on the communications analyzer should be between 7.

At this point both forward and reverse audio paths are unmuted and the conversation can take place. From the overhead message, the majual will be able to determine whether or not it is in its home system, and the range of channels to scan for paging and access. The switch then connects the incoming call to the appropriate circuit leading to the cell in contact with the cellular telephone.

SAT or DSAT is generated by the cell site, checked for frequency or accuracy by the cellular telephone, then transponded that is, not merely reflected but generated and returned to the cell site on the reverse voice channel REVC. The 2nd LO is celula down then phased shifted before being mixed with the IF signal.

Status Display level is the power-up state in manual test mode. U will oscillate at a frequency of The cell sites and the mobiles and portables communicate through the use of data or, in the case of AMPS, through the use of data ceular tones. UB is then used to invert the state and provide a low state at V1. On an AMPS celulxr the hand-off is executed by interrupting the conversation with a burst of data called blank and burst containing the new voice channel assignment. For each step, the display shows factory default NAM data.

Then enter 5 5.

Essentially DTC minus audio and vocoders 2. Transmit power level commands are sent to the cellular telephone as required to maintain the received signal strength within prescribed limits. The voice channel assignment is sent to the cellular telephone on the access channel. A lower voltage level at BIAS denotes digital mode and a higher voltage level denotes analog mode. The output of the VCO is split into two paths.

The phone will now be in Step 1 of the NAM. The signal is prescaled and sent through a phase lock loop circuit for frequency locking.

The speaker, vibrator, and flex should be exposed.
