9 Cross-connections
Cross-connections need to be created for routing transmission capacity to the
other BTSs in a chain or loop transmission topology.
Cross-connections are only supported with the FXC type transmission units.
The BTS has to be commissioned before creating the cross-connections.
9.1 Creating cross-connections
Cross-connections are created with the E1/T1 Manager (Transmission Unit
Manager) application in Nokia BTS Manager.
Cross-connections define how signals are routed from an FXC transmission unit
to another transmission unit. Cross-connections are created into inactive banks.
The cross-connections in the active banks are in use, whereas those in inactive
banks can be used for creating or editing cross-connections. The procedure below
describes how to create bi-directional cross-connections.
Creating bi-directional cross-connections:
1. Open E1/T1 Manager by selecting TRANSMISSION | OPEN on the BTS
Manager menu bar. The E1/T1 Manager is launched and the BTS Manager
session terminates.
2. Select CONFIGURATION | CROSS-CONNECTIONS on the E1/T1
Manager menu bar. The Cross-connections window opens, as shown in
Figure 34.
