LINE-SIDE CONNECTIONS
The DS2149DK/DS21349DK implements the Tx and Rx line interface networks recommended in the DS2149 and
DS21349 data sheets and as shown in
Figure 2
. To connect the DS2149DK/DS21349DK to T1 or J1 test
equipment, connect the equipment to the RJ48 connector or to the two bantam connectors, J2 and J3. Please
notice the relays disconnecting TTIP and TRING on T1 and T2. These relays disconnect the series resistors R4
and R5, which is recommended for some long-haul configurations. Pin 16 on the system connector serves as the
control line for the relays. When pin 16 is high, T2 is enabled with TTIP and TRING. When it is held low, T1 is
enabled with TTIP and TRING.
