Introduction
The TC8619 is designed for quick and easy installation. First, configure the unit for
your specific application by setting the Line Code, and Line Length DIP switches.
Once configured, you can connect the Ethernet, T1/E1 signal source and power.
3.2
Setup
1.
Set the appropriate Line Code for your application with the rear panel DIP
switch SW4. "On" for B8ZS (T1) or HDB3 (E1). "Off" for AMI.
2.
For T1/E1 applications, set the appropriate T1/E1 Line Length with the rear
panel DIP switch SW6, SW7, & SW8. It is set to "0-133 feet" by default.
3.
Set the appropriate T1/E1 timing mode with rear panel DIP switch SW3. There
should be one and only one clock source throughout the entire T1/E1 network.
If two TC8619 units are connected back to back, one unit should set to
"Internal" timing mode, and the other unit should set to "RX Loop" timing
mode.
4.
Verify the Ethernet pin connections as well as the T1/E1 pin connections. After
that, connect the two TC8619 units with a T1/E1 cable.
5.
Connect the Ethernet signal source to the TC8619 Port 1 RJ-48 connector.
6.
Verify the corresponding channel's Ethernet Link LED is solidly lit to indicate
that data is being received. If the Link LED does not light up solidly on a
particular channel, it usually indicates incorrect connections at the Ethernet
port.
