Connecting the trunk modules
The trunk module cables are either coaxial (for DS3 or E3) or fiber optic (for
OC-3/STM-1 optical).
OC3-ATM trunk module connections
An OC3-ATM trunk module requires duplex SC fiber optic cable. Bind excess cable
lengths in a figure-eight pattern. Do not wind excess cable into circular coils.
Note
Clean any fiber optic cables prior to connecting them.
To connect the cables to an OC3-ATM trunk module, carefully insert the head of each
cable into a connector on the trunk module. See Figure 2-7.
Figure 2-7. Connecting an OC3-ATM trunk module
DS3-ATM or E3-ATM trunk module connections
Connect the DS3 or E3 line to the RX LN and TX LN connectors on a DS3-ATM or
E3-ATM trunk module, using two 75-ohm coaxial cables (RG 59/U).
To configure a redundant connection, connect the BY connectors on the primary
trunk module to the LN connectors on the backup trunk module (see Figure 2-8). If
the primary port fails, the traffic is switched to the secondary module’s port.
