I
Receive Tip and Ring Inputs. Connects directly to the receive T1 twisted pair.
These inputs are transformer coupled and terminated at 100 ohms. See Figure
2.

TXTIP
TXRING
O
Transmit Tip and Ring Outputs. Connects directly to the transmit T1 twisted
pair. Output signal level is programmable via the LB0 to LB2 pins. (See Table 3.)

–
Loop Power Connections. These pins connect to the internal center–taps of
the transmit and receive transformers. They provide access to the DC power
on the T1 line (may not be provided by carriers in the future). Tie together if no
simplex power arrangement is needed.
