1、Frequency band
The frequency range of M-Link series digital microwave transmission system is 7/8/13/15/18GHz. It is conformity with the standards of china MII, ETSI and FCC. It has the flexible interface configurations to support 4/8/16E1 and Ethernet connection.
2、Characteristic of M-Link 2.1 Card structure: Module design, only change the interface card ,which can change the radio system to the capacity 4E1/8E1/16E1.
Provide the 75ohm BNC interface and 120ohm RJ48 interface .
2.2 4E1-16E1 expand smoothly
When the system capacity expand ,only to do is change the interface card, you can get 4E1-8E1-16E1.
When the system capacity is expand , ODU don’t need to change, it can adjust the bandwidth to 7M/14M/28M according to the IDU’s capacity.
2.3 Support E1 and IP at the same time:
The perfect combine of the E1 and IP，M-Link can support E1 interface and IP interface at the same time，the capacity can divided dynamically.
E1 without use can be packed automatically to transport through IP.
2.4 Super embedded LCD NMS
Embedded NMS and LCD function，support all the configuration and display（set the frequency point, power, etc）,very convenience for the engineering of operating and maintaining the radio onsite, don't need the help of other equipments.
2.5 1+1 same frequency hot-standby Support the real 1+1 mode of same frequency hot standby.
Combiner
2.6 1+1 different frequency standby Support the real 1+1 mode of different frequency standby.
 2.7 1+1 SD and without SD
When the system use hot standby of same frequency, it can be configured as SD structure with two antennas.
No matter what kind of structure the system use（ same frequency or different frequency hot standby）， they all can be use the combiner and one antenna, that is without SD.
2.8 Base on SNMP network management system
Support SNMP V2.0 protocol，can manage the radio system through the third network management software，can manage about 4096 links of radio.
2.9 SNMP network management
SNMP network system support the interface connect , it can transport the information of the next station without other equipment’s help, and not occupy the service channel.
2.10 Professional network planning software
3、Typical mode of operation solution
3.1 Mobile base station interconnection
3.2 WiMAX base station interconnection
3.3 Enterprise voice and data Access Service of voice and data of one company access to the key nod of service provider（Such as：office building，dwelling house, big corporation，internet bar, etc）.
3.4 Dedicated transparent transmission channels
3.5 Emergency communication
