Function
Line Receiver input 1, port 4
Analog input from the external transformer. Selected if
LIM1.DRS is cleared.
Receive Optical Interface Data, port 4
Unipolar data received from a fiber-optical interface with
2048 kbit/s (E1) or 1544 kbit/s (T1/J1). If CMI coding is
selected (MR0.RC(1:0) = ´01
internal DPLL recovers clock an data; no clock signal on
RCLKI2 is required.
Line Receiver input 2, port 4
Analog input from the external transformer. Selected if
LIM1.DRS is cleared.
Receive Line Switch, port 4
Connector of the analog switch.
Line Receiver input 1, port 5
Analog input from the external transformer. Selected if
LIM1.DRS is cleared.
Receive Optical Interface Data, port 5
Unipolar data received from a fiber-optical interface with
2048 kbit/s (E1) or 1544 kbit/s (T1/J1). If CMI coding is
selected (MR0.RC(1:0) = ´01
internal DPLL recovers clock an data; no clock signal on
RCLKI2 is required.
Line Receiver input 2, port 5
Analog input from the external transformer. Selected if
LIM1.DRS is cleared.
Receive Line Switch, port 5
Connector of the analog switch.
Line Receiver input 1, port 6
Analog input from the external transformer. Selected if
LIM1.DRS is cleared.
Receive Optical Interface Data, port 6
Unipolar data received from a fiber-optical interface with
2048 kbit/s (E1) or 1544 kbit/s (T1/J1). If CMI coding is
selected (MR0.RC(1:0) = ´01
