Dual BNC Interface (DS3)
A TMG3200 with 3 sets of BNC connectors enables the connection to DS3 lines. See figure 2.7 on
page 17
Note
All ports may not be active. DS3 ports are activated by software license; the number of
active ports depends on the licenses purchased.
To connect the TMG3200 (DS3) to the PSTN:
1. Start with the Dual BNC port pair #1 (right-most) as shown in figure 2.7 on page 17. Connect one
pair of BNC cables between this port and the DS3 line.
2. Repeat step 1, using the next available pair of BNC PSTN interface ports.
