Description
MLNRZO1
4
HDB3 Decoder #1 NRZ Output.
HDB3 Decoder #1 NRZ output clocked on the rising edge of MLCK1.
MLNRZO2
11
HDB3 Decoder #2 NRZ Output.
HDB3 Decoder #2 NRZ output clocked on the rising edge of MLCK2.
MLNRZO3
20
HDB3 Decoder #3 NRZ Output.
HDB3 Decoder #3 NRZ output clocked on the rising edge of MLCK3.
MLNRZO4
27
HDB3 Decoder #4 NRZ Output.
HDB3 Decoder #4 NRZ output clocked on the rising edge of MLCK4.
MLBPV1
3
HDB3 Decoder #1 Bipolar Violation Alarm.
This open collector output pulses every time a bipolar
violation occurs in the decoding process.
MLBPV2
10
HDB3 Decoder #2 Bipolar Violation Alarm.
This open collector output pulses every time a bipolar
violation occurs in the decoding process.
MLBPV3
19
HDB3 Decoder #3 Bipolar Violation Alarm.
This open collector output pulses every time a bipolar
violation occurs in the decoding process.
MLBPV4
26
HDB3 Decoder #4 Bipolar Violation Alarm.
This open collector output pulses every time a bipolar
violation occurs in the decoding process.
MESA1
32
Multiplexer Tributary #1 Elastic Store Alarm Indication.
Multiplexer justification status for tributary
#1. A high indicates bit stuffing on the current frame. A low indicates an information bit. When
externally filtered, this signal can be used to indicate elastic store failure or incorrect tributary
frequency.
MESA2
33
Multiplexer Tributary #2 Elastic Store Alarm Indication.
Idem as MESA1 with tributary channel 2.
MESA3
34
Multiplexer Tributary #3 Elastic Store Alarm Indication.
Idem as MESA1 with tributary channel 3.
MESA4
35
Multiplexer Tributary #4 Elastic Store Alarm Indication.
Idem as MESA1 with tributary channel 4.
MHNRZO
42
High speed Multiplexer NRZ Output.
Multiplexer NRZ data clocked out on the rising edge of
MHMUXC.
MHDPO
46
HDB3 Encoder #5 Positive Data Output.
HDB3 Encoder #5 Positive rail clocked out on the rising
edge of MHHDB3C.
MHDNO
47
HDB3 Encoder #5 Negative Data Output.
HDB3 Encoder #5 Negative rail clocked out on the rising
edge of MHHDB3C.
DLNRZO1
74
Demux Tributary #1 NRZ Output.
This signal is clocked out on the rising edge of DHDMXC and
transitions are coincident with the falling edge of DLCO1.
DLNRZO2
72
Demux Tributary #2 NRZ Output.
This signal is clocked out on the rising edge of DHDMXC and
transitions are coincident with the falling edge of DLCO2.
DLNRZO3
70
Demux Tributary #3 NRZ Output.
This signal is clocked out on the rising edge of DHDMXC and
transitions are coincident with the falling edge of DLCO3.
DLNRZO4
68
Demux Tributary #4 NRZ Output.
This signal is clocked out on the rising edge of DHDMXC and
transitions are coincident with the falling edge of DLCO4.
DLCO1
73
Demux Tributary #1 Clock Output.
Demultiplexer side recovered clock of tributary #1. This clock has
a duty cycle of 75% and is gapped at points in the frame where tributary data is not present (i.e., frame
word). The maximum gap is 3 clocks at the frame word location. The frequency will match that of the
far end multiplexer tributary input. This signal is clocked out on the rising edge of DHDMXC.
DLCO2
71
Demux Tributary #2 Clock Output.
Demultiplexer side recovered clock of tributary #2. See DLCO1
description.
DLCO3
69
Demux Tributary #3 Clock Output.
Demultiplexer side recovered clock of tributary #3. See DLCO1
description.
DLCO4
67
Demux Tributary #4 Clock Output.
Demultiplexer side recovered clock of tributary #4. See DLCO1
description.
DLDPO1
84
HDB3 Encoder #1 Output +.
HDB3 Encoder #1 positive rail output clocked out on the rising edge of
DLCI1.
