2.2.4.3 Configurations at Multi-terminal Sites
Several terminals can be integrated in the same indoor AMM. Different
configurations, t raffic capacities and radio frequencies can be combined. A site
can be upgraded easily by substituti ng and/or adding plug-in units.
• One AMM 2U-3 can hold:
− Two unprotected (1+0) terminals or one protected (1+1) terminal
− One SAU
• One AMM 4U can hold:
− Up to four unprotected (1+0) terminals
− Two protected (1+1) terminals
− One protected (1+1) terminal plus one or two unprotected (1+0)
ter minals
− One SAU
Software controlled traffic routing between the terminals minimizes site cabling,
see Section 3.12 on page 74.
One SMU can contain multiplexers/demultiplexers for two term inals. The
terminals can also share the same optional SAU. The SAU offers analog or
digital service channels as well as parallel inputs/outputs for integration of
alarms and exter nal equipment control.
