Page 11: System Architecture
System Architecture Figure 1-2 illustrates the MRU system architecture. In the downlink, at the headend, the BTS/BDA signal is conditioned at the headend unit (e.g. integrated headend unit IHU)), by the service specific radio interface modules (RIM), ensuring a constant RF level. -
Page 12: System Monitoring And Management
System Monitoring and Management The MRU is centrally managed via the headend control module SW management application (v1.6 and higher). Figure 1-3 shows the management tabs of the selected MRU unit. Refer to the HCM and Web Management User Manual (v1.6 and higher) for information on how to configure and manage the MRU remote unit. -
Page 13: Mru Interfaces
Power amplifier modules (PAM) – internal service specific power amplifier module that interfaces to an optical interface module (OIM) at the headend site via an SMF pair and supports one service. MRU supports up to five SISO bands. The PAM provides the additional amplification on the DL signals routed from the OIM towards the multiplexer; PAMs are pre-installed in designated slots according to supported band. - Page 14 DC models - two types of terminal block connectors: • CLASS2 (default) – two “DC In” 8-pin terminal block connectors for remote feed: one pair for each PAM ( total of five pairs) and one pair for the FAM+OPTM; one RSV pair •...
