Data Sheet
1)
Outputs of the U-Transceiver:
Activation Indication
The U-transceiver has established transparency of transmission. The downstream
device is requested to establish layer-1 functionality.
Activation Indication Loopback
The U-transceiver has established transparency of transmission. The downstream
device is requested to establish a loopback #2.
Activation Request
The downstream device is requested to start the activation procedure.
Activation Request Loop-back
The U-transceiver has detected a loop-back 2 command in the EOC-channel and has
established transparency of transmission in the direction IOM
downstream device is requested to start the activation procedure and to establish a
loopback #2.
Deactivation Confirmation
Idle code on the IOM
Deactivation Request
The U-transceiver has detected a deactivation request command from the LT-side for
a complete deactivation or a S/T only deactivation. The downstream device is
requested to start the deactivation procedure.
Error Indication 1
The U-transceiver has entered a failure condition caused by loss of framing on the
U-interface or expiry of timer T1.
