ZXG10 OB06 ZTE Integrated Outdoor GSM Base Station Technical Manual
4 Confidential and Proprietary Information of ZTE CORPORATION
2. It supports GSM900, EGSM900, GSM850, GSM1800 and GSM1900
systems; it also supports modules of different frequency bands
inserted in the same cabinet.
3. It provides the following TCH services:
TCH/FS: Full-rate voice traffic channel
TCH/HS: Half-rate voice traffic channel
TCH/EFS: Enhanced full-rate voice traffic channel
TCH/F9.6: 9.6 kbit/s full-rate data traffic channel
TCH/F4.8: 4.8 kbit/s full-rate data traffic channel
TCH/F2.4: 2.4 kbit/s full-rate data traffic channel
It supports service channels related with GPRS service
4. It provides a diversity receiving function. Main diversity technologies
are space diversity, frequency diversity, time diversity and polarization
diversity.
5. The receiving end adopts the Viterbi soft decision algorithm, improving
the channel decoding performance and increasing the system receiving
sensitivity and anti-interference capability.
6. It supports frequency hopping, improving the system capability against
Rayleigh fading.
7. It supports the discontinuous transmission (DTX) mode, only
transmitting comfort noise in the voice non-activated period, and
reducing the transmitter power and general interference level in the air
signaling.
8. It can calculate the time advance.
9. For GSM 900 and EGSM 900 systems, it supports configurations with
power consumption of 40 W or 80 W. For GSM1800, GSM1900 and
GSM850 systems, it supports 40 W configuration.
10. One OB06 (40 W configuration, in this document, 40 W for the GMSK
mode, and 25 W for the 8PSK mode) supports 6 TRXs, supports
extension of 18 TRXs at the same site, and one site supports extension
of S6/6/6.
11. One OB06 (80 W configuration, in this document, 80 W for the GMSK
mode, and 50 W for the 8PSK mode) supports 3 TRXs, supports
extension of 9 TRXs at the same site, and one site supports extension
of S3/3/3.
12. It supports star, chain and tree configuration of Abis interfaces.
13. It supports satellite transmission links of Abis interfaces, with the
unidirectional transmission delay of Abis interfaces being 260 ms.
14. It supports LapD signaling 1: 4 TEI multiplex of Abis interfaces, that is,
having 4 pieces of LapD signaling multiplexed into one 64 Kb/s
signaling timeslot through TEI.
15. When multiple OB06s are cascaded, the automatic crossover protection
function is provided for the Abis interface link when any OB06 is
powered off.
