TC1910
User's Manual
Rev. 2.0 (A0.3)
Before unpacking any equipment, inspect all shipping containers for evidence of external damage caused
during transportation. The equipment should also be inspected for damage after it is removed from the
container(s). Claims concerning shipping damage should be made directly to the pertinent shipping agencies.
Any discrepancies should be reported immediately to TC Communications' Customer Service Department.
The TC1910 should be located in an area that provides adequate light, work space, and ventilation. Avoid
locating it next to any equipment that may produce electrical interference or strong magnetic fields, such as
elevator shafts or heavy duty power supplies. As with any electronic equipment, keep the unit from excessive
moisture, heat, vibration, and freezing temperatures.
Each TC1910 unit is powered via a rear panel's terminal block connector. There are two pairs of terminal
block connectors ("PWR A" and "PWR B") for power redundancy, the power LEDs on the front panel will
light according to which power jack(s) is/are connected. The power is 12 VDC @500mA, (24 VDC and AC
90 VAC to 240 VAC are optional).
The RJ-45 & RJ-11 female connectors for the electrical signals are located on the rear panel.
TC1910's need to work in pairs in an Ethernet network. One unit needs to be set to Master “MSTR” and the
other one needs to be set to Slave “SLVE” using the front panel DIP switch. If the TC1910 pair is separated
by a firewall, the Master unit should be the one sitting outside of the firewall. (Please refer to P.7 "Dip-Switch
Functions" for setting the unit to default setting.)
All units come with default Slave settings, please refer to the "Quick Start/Test" section on P.18 for simple
setup examples.
Note:
The TC1910 FXS configured unit(s) will ring the phone channel during initialization, and the
phone set connected on the FXS channel should ring 10 seconds after power up.
