2.5.2 RJ48 Type Interface (T1/E1/J1)
A TMP6400 with 16 RJ48 type ports enables the connection to T1/E1/J1 lines. The termination
impedance is set at 100 ohms for T1 lines and 120 ohms for E1 lines. It is possible to connect an
external balun in order to convert to 75 ohms. See figure 2.7 on page 17. If you are making your own
cables, refer to figure 2.8 on page 18 for crossover or straight cable wiring connections.
Note
All ports may not be active. T1/E1/J1 ports are activated by software license; the number
of active ports depends on the licenses purchased.
To connect the TMP6400 (RJ48 type) to the PSTN:
1. Start with port 1 located at the top and left-most position. Connect one cable between this port and
the T1/E1/J1 line (figure 2.7 on page 17).
2. Repeat step 1, using the next available port.
