Quick Start Guide
3.1
Introduction
The TC8612 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 Dry Contact, T1/E1 signal source and power.
3.2
Setup
1.
Select the appropriate Line Code for your application with the front panel dip
switch SW4. “On” (Down) for B8ZS(T1) or HDB3(E1) and “Off” (Up) for
AMI .
2.
For T1 applications, set the Copper Line Length with the front panel SW6,
SW7, & SW8. Generally, it will be factory set to "0-133 feet."
3.
For E1 applications, set the proper impedance for your application with the
front panel SW6, SW7, & SW8.
4.
Set the appropriate T1/E1 timing mode with rear panel DIP switch SW3.
Thereshould be one and only one clock source throughout the entire T1/E1
network.
If two TC8612 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. “On” (Down) for internal timing mode. "Off" (Up) for Rx loop timing
mode.
5.
Make sure to verify the Dry Contact as well as the T1/E1 pin connections.
Then make the actual connections to and from the TC8612s.
6.
At the front panel, apply the dry contact signals by plugging in the RJ11
connector plugs one at a time. By opening and closing the TC8612 dry contact
closure detector pins, verify that the corresponding channel's "DET" LED turns
on to indicate the signal is being received. If the "DET" LED do not turn on for
a particular channel, it usually indicates incorrect connections at the RJ11 input
port (double-check your connections and verify them with the connection
diagrams in the Electrical Signal Interface section).
7.
After the T1/E1 connection is established, the front panel "ALM" LED
shouldbe off and the "SYNC" LED should be lit solidly.
8.
If the front panel "ALM" LED is solidly lit, press and hold the "R2" (“Reset
Too”) button for 3 seconds until the "ALM", "BPV", "CRC", and "SYNC"
LEDs are flashing. The alarm will reset after the "R2" button is released.
