Digital Radio TestSet

A-BIS INTERFACE In order to perform comprehensive, "real environment", stand-alonetesting of a base station, the industrial test set must be capable of controllingthe BTS. The 6113 is unique in its ability to measure RF transmis- sions as well as connecting to the BTS via the A-bis interface.Through the use of the specific BTS manufacturers' Operation &Maintenance (O&M) commands, the 6113 is able to emulate the Base Station Controller (BSC) and take complete control of the BTS. This is accomplished automatically without the need for userintervention. The A-bis interface also allows the user to make BitError Ratio (BER) measurements on both the receiver and trans- mitter, as specified in GSM rec 11-20/11-21. The 6113 A-bis inter-face also permits a wide variety of other test functions to be per-formed that could not otherwise be done.The A-bis interface of the 6113 supports a bi-directional communi-cations and control link at either 2.048 Mbit/s (CEPT standard) or1.544 Mbit/s (US T1) standard. With one traffic channel and twosignaling channels of either 16 or 64 kbit/s, the 6113 accommodates the fact that the mapping of traffic and signaling channels are man-ufacturer specific. •Easyto use, fullyintegrated, soft keydriven BTS test set•Support forGSM850, GSM900,GSM1800 and GSM1900•Comprehensive test of transmitterandreceiver•Options to control all majorBTS types •Manual and fullyautomatic testing •Test sequences forfull customization•Optimized forinstallation and commis-sioning, routine maintenance, fault diag-nosis and production testing•A-bis interface forfull BTS control and biterrorratio (BER) measurements•Two PC Card slots fordata storage, fieldupgrades and software enhancements The Racal Instruments Wireless Solutions (RIWS)6113Digital Radio Test Set provides a widerange oftest and measurement functions toenable fast manual orautomatic testing of GSM850, GSM900, GSM1800 orGSM1900Base TransceiverStations (BTSs).
