Figure 4b: RJ-45 Manual Configuration
SW6 (6), SW7 (7), SW8 (8) - Link Modes
The DIP-switches shown in Figure 3, on the previous page, are used to configure the link modes. It is
recommended to keep link mode DIP-switches in the default Down position during the initial installation.
After the circuit has been tested and operational, configure the module for the desired mode.
For detailed information on the operation of the different Link Modes, download the application note

SW1 (9) and SW2 (10): Backplane "Auto/Man"
When these DIP-switches are in the Down "Auto" position (factory default), the Ethernet Backplane Port
of the TM3 is normally disabled, but automatically connects to adjacent 4xT1/E1 MUX modules creating
a MUX group. When these DIP-switches are in the Up "Man" position, the backplane port is forced on
and Ethernet traffic is sent to and received from the backplane partner. The DIP-switch must be in the
Down "Auto" position for the TM3 module to create a MUX group.
SW3 (11): Master/Slave "M/SL"
Setting this DIP-switch to the Down "M/SL" position (factory default), allows chassis mastership to be
automatically negotiated by the installed management modules. To designate the TM3 module as the
master of the chassis when an Network Management Module (NMM2) is not installed, set the DIP-switch
on the module to the Down "M/SL" position, and set the DIP-switch on the other installed management
modules to the Up "SL" position to enable Slave-Only mode
SW4 (12): Reserved
This DIP-switch is for factory use only and must always remain in the Down "Off" position (factory default).

Figure 7: Bank 1 DIP-switches
SW1 (1) - SW4 (4): Local Loopback Port 1 - Port 4 "Off / LBx"
These DIP-switches control the local loopback function for each T1/E1 port. When these DIP-switches
are in the "LBx" position, the corresponding port initiates a local copper loopback. An AIS (all 1s signal)
from the local port is transmitted across the fiber and out the corresponding T1/E1 port on the remote
unit. When these DIP-switches are in the "Off" (default) position, the port functions normally.
