Purpose of this Cellular Adapter
This Cellular Adapter in conjunction with the HP 8920 Series RF
Communications Test Set enables testing of the following cellular systems:
TIA/EIA-136 (DCCH), TIA/EIA-627 (DAMPS or TDMA), and AMPS. This
Cellular Adapter contains the hardware and firmware necessary to test DCCH and
DAMPS. The AMPS hardware and firmware is contained in the HP 8920.

test an TIA/EIA-627 phone, use System Type DAMPS.
Items in this manual are valid for both DCCH and DAMPS, unless otherwise
noted. Symbols that alert you to system-specific topics are shown in
