Secure the cable connectors to the chassis with a cable cinch-tie around the
connectors and through the security fixtures on the left side of the line
connectors on the chassis. (Optional, if your cable connectors have a slot to
engage the locking tab.)
Connecting the trunk modules
The trunk module cables are either coaxial (for DS3 or E3) or fiber optic (for
OC-3/STM-1 optical or OC-12/STM-4 optical).
Optical trunk module connections
The OC3-ATM and OC12-ATM trunk modules require 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 or OC12-ATM trunk module, carefully insert
the head of each cable into a connector on the trunk module. An example of this
connection on an OC3-ATM trunk module is shown in Figure 2-4.
Figure 2-4. 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 DS3 or E3 connection, connect the BY connectors on the
primary trunk module to the LN connectors on the backup trunk module as shown
in Figure 2-5. If the primary port fails, the traffic is switched over to the secondary
module’s port.
