Pin Descriptions
A6
RL1.1
I (analog) –
Line Receiver input 1, port 1
Analog input from the external transformer. Selected if
LIM1.DRS is cleared.
ROID1
I
–
Receive Optical Interface Data, port 1
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
b and LIM0.DRS = 1), an
internal DPLL recovers clock an data; no clock signal on
RCLKI2 is required.
A8
RL2.1
I (analog) –
Line Receiver input 2, port 1
Analog input from the external transformer. Selected if
LIM1.DRS is cleared.
A7
RLS21
IO
(analog)
–
Receive Line Switch, port 1
Connector of the analog switch.
A4
RL1.2
I (analog) –
Line Receiver input 1, port 2
Analog input from the external transformer. Selected if
LIM1.DRS is cleared.
ROID2

LIM1.DRS is cleared.
ROID3
I
–
Receive Optical Interface Data, port 3
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
