PPP packet test (option) PPP (built-in server) test When a PC is connected (RS-232C) to the MD8480C, PPP protocol data communication testing can be performed. PPP is the protocol used when connecting via dial-up. For additional PPP testing, the PPP protocol stack is built into the MD8480C so the PPP protocol can be terminated in the MD8480C. High-speed communications between the PC and MD8480C is pos- sible using Ethernet (14 Mbps downlink and 384 kbps uplink). The MD8480C is a Base Station Simulator for testing 3.5G W-CDMAmobile phone stations with High Speed Download Packet Access (HSDPA) functions. It has an air interface conforming to 3GPP spec- ifications, and permits a full range of application tests. Capabilities include testing chipset and mobile station coding/decoding process- ing, voice and packet communications, and MS-to-MS testing (re- quires two MD8480C units). MD8480C protocol sequence tests in- clude position registration, origination/termination, handover (op- tion), and disconnection from a mobile station/network. Moreover, by adding optional functions for GSM/GPRS, handover tests between W-CDMA and GSM/GPRS can be performed. The MD8480C is ideal for developing UMTS mobile UE supporting glob- al services, as well as for evaluating high-function application soft- ware for mobile stations that support HSDPA.

MS-to-MS and other testsUser data test Any data can be inserted to the send DTCH and demodulated DTCHdata can be captured externally. This permits tests such as error rate measurement. Video call test (option) MS-to-MS test

Features?

When a video call using the ISDN interface is connected to the MD8480C, audio and video communications tests can be performed between the mobile station and an external video terminal. When two MD8480C units are connected by 10BASE-T/100BASE- TX, end-to-end UE testing between two mobile stations is supported. Supports 3GPP Release 5 (HSDPA)

Coding and decoding function tests Main performance and applications?

W-CDMA mobile station coding and decoding functions can be test- ed using the setup shown in the diagram below. In the coding test, fixed and variable data (such as PN9) output from the W-CDMA mobile station coding unit is compared with the de- coding results shown on the Trace screen. In addition, simultaneous BLER and BER measurements are sup- ported (BER tests require an external BER counter) and received signal timing errors can be displayed. In the decoding test, MD8480C fixed and variable W-CDMA data (such as PN9) is output for comparison with the mobile station de- coding results. W-CDMA/HSDPA ?

Application tests?

Voice and data communication tests The MD8480C can perform a variety of application tests. AMR voice test When a handset (standard accessory) is connected to the MD8480C, voice calls with the mobile station can be tested. IP packet test When a PC is connected (10/100BASE-T) to the MD8480C, IP pro- tocol data communication testing can be performed. http://www.anritsu.com 276
