10. Cross Connections
Embedded cross connect switch
The embedded cross-connect switch distributes capacity to each of the interfaces.
Traffic can be distributed to any of the possible 32 interface ports as well as the integrated Ethernet
interface. This provides the flexibility to reconfigure traffic as the network demand changes, or groom
user traffic onto E1 / T1 bearers between equipment.
The maximum number of simultaneous cross connections per terminal is 256. During cross connection
activation, a progress bar shows the number of ports that have activated.
Link Capacity Utilization
Cross connections are able to utilize all of the available capacity of the link on lower capacity radio
links (< 2048 kbit/s gross capacity, i.e. up to 500 kHz, 16 QAM). However, as higher capacity radio
links allocate bandwidth for E1 / T1 timeslot connections on 64 kbit/s boundaries, some capacity may
be unusable (< 64 kbit/s).
The Cross Connections application
The Cross Connections application is a software application that is used to:
manage the cross connections switches within the terminals
create cross connections between the traffic interface ports within one terminal or between the
near end and far end terminals via the radio bearer
create cross connections between symmetrical traffic interface ports with the symmetrical
connection wizard
get the current cross connection configuration from the terminal
send and activate the cross connection configuration
save and load configuration files
The Cross Connections system requirements
The Cross Connections application requires the following minimum PC requirements:
1024 x 768 screen resolution
Ethernet
