Index
Unique interface index of the serial interface.
Type
The serial physical interface type
none(1)    interface disabled
x21(2)     X21(V11) terminated     (sync)
v35(3)     V35(V11 & V28)          (sync)
v36(4)     V36(V10 & V11)          (sync)
x21bis(5)  RS232(V28)              (sync)
rs422(6)   X21(V11) not terminated (sync)
rs449(7)   RS449(V10 & V11)        (sync)
rs530(8)   RS530(V10 & V11)        (sync)
rs530a(9)  RS530A(V10 & V11)       (sync)
Enumerations:
  • none (1)
  • x21 (2)
  • v35 (3)
  • v36 (4)
  • x21bis (5)
  • rs422 (6)
  • rs449 (7)
  • rs530 (8)
  • rs530a (9)
Connector
The physical connector type.
When configured as DCE the pins on the output connector
act as a DCE interface. If configured as DTE on the output
connector act as a DTE interface.
dte(1)	DTE output pins  
dce(2) 	DCE output pins 
Enumerations:
  • dte (1)
  • dce (2)
Leads
The value of IfLeads has influence on the state of the
physical layer (L1State). When configured as
IfLeads=enabled, the state of the physical layer
depends on the signals of the control interface pins
Indication/Control on X.21 or RTS/CTS on the other
protocols. 
When configured as IfLeads=disabled, the state of the 
physical layer stays always up.
enabled(1)		interface pins accepted.	
disabled(2)		ignore interface pins.
Enumerations:
  • enabled (1)
  • disabled (2)
Clock
The physical layer (layer 1) clocking mode.
When configured as AUTO the clock provided depends what is
configured on connector. If connector is configured as
DTE clock must provided from external, if the connector is
configured as DCE clock is generated and is provided at
the output pins.
It is possible to configure the clock independed from
connector type. EXTERNAL clock means the clock must provided
by the external device and INTERNAL clock means the clock
is generated by the brick and is provided on the output pins.
X.21      one clock line is provided.
V.35/V.36 two clock lines are provided.
auto(1)	connector = DTE = extern,
DCE = intern
extern(2)	clock pins operate as input.
intern(3)	clock pins operate as output.
Enumerations:
  • auto (1)
  • extern (2)
  • intern (3)
ClockEdge
The value of IfClockEdge influences the (internal) active
clock edge(s) for generating/sampling data on the serial line. 
This value should be left on DEFAULT under normal
circumstances. Nevertheless, in some rare cases it is possible
the connection does not work properly. This behaviour may be
produced by timing inconsistencies over the serial line in
conjunction with some disadvantageous clock/data processing
at the DTE/DCE devices and is very device couple specific. The
several settings allow shifting data generation/sampling by
half a cycle of the incoming serial clock. The variation of
this setting can help to make a not working connection
working. A typical sign for an erroneous situation in this
sense is the reception of massive corrupted frames at one or
both communication end points.
default(1)		the clock edges for generating/sampling
are the default ones
rxc-inverted(2)	the receiver's data sampling is shifted
by half a cycle of incoming serial
clock (currently only supported by
X8500)
txc-inverted(3)	the transmitter's data generation is
shifted by half a cycle of incoming
serial clock
rxc-txc-inverted(4)	both the receiver's data sampling and
the transmitter's data generation is
shifted by half a cycle of incoming
serial clock (currently only supported
by X8500)
Enumerations:
  • default (1)
  • rxc-inverted (2)
  • txc-inverted (3)
  • rxc-txc-inverted (4)
Speed
The serial interface speed in bits per second. The range
is dependant on the type of the line (balanced/unbalanced)
and the quality and length of the cable.
Over a short distance (about 5 m) and with a shielded cable 
speeds of up to 8 Mbit/sec are possible.
L2Mode
The layer 2 mode. This value has influence on the
HDLC address field (first byte of a HDCL frame). When
configured as DTE the address in a command frame is
0x01, when configured as DCE it is 0x03. For
response frames it is vice versa. When configured as
AUTO, layer 2 is set to the same as connector is set.
dte(1)	HDLC address 0x01
dce(2)	HDLC address 0x03
auto(3)	same as conector = DTE=0x01 DCE=0x03
Enumerations:
  • dte (1)
  • dce (2)
  • auto (3)
CableDetection
Cable autodetection for:
manual(1)    disabled
auto(2)      serialIfType and serialIfConnector
iftype(3)    serialIfType
connector(4) serialIfConnector
Enumerations:
  • manual (1)
  • auto (2)
  • iftype (3)
  • connector (4)
CableType
Show the detected cable type:
unknown(1)         cable type unknown.
x21(2)             DB15, X27/V11    (sync)
v35(3)             M34,  V35/V10    (sync)
v36(4)             DB37, V10/V11    (sync)
x21bis(5)          DB25, RS232/V28  (sync)
not-supported(255) cable detection not supported
Enumerations:
  • unknown (1)
  • x21 (2)
  • v35 (3)
  • v36 (4)
  • x21bis (5)
  • not-supported (255)
CableConnector
Show the detected cable connector type:
dte(1)           DTE cable 
dce(2)           DCE cable
unknown(3)       cable type unknown.
not-supported(4) cable detection not supported.
Enumerations:
  • dte (1)
  • dce (2)
  • unknown (3)
  • not-supported (4)
Bundle
Index of the bundle to aggregate multiple Channels
to one interface.
L1State
The serial physical layer state
dn(1)		physical layer is inactive
up(2)		physical layer is active
Enumerations:
  • dn (1)
  • up (2)
SpeedReal
In DCE/internal clock mode this is the rounded speed in bits per
second, because not every baudrate can exactly be generated.
In DTE/external clock mode this is the measured speed, where
measurement is possible, or the configured speed in serialIfSpeed.
RxPackets
Count of received valid Frames.
RxOctets
Count of received bytes.
TxPackets
Count of transmitted valid Frames.
TxOctets
Count of transmitted bytes.
RxResets
Count of receiver resets. Under rare circumstances it
might be necessary to reset the receiver to work
properly.
RxAborts
Count of receiver aborts. The sender of a frame can
indicate a frame as aborted with a special Abort
sequence.
RxOverruns
Count of receiver overruns. If the serial port is unable
to grant sufficiently soon/often the bus, the
RxFIFO may fill up. This leads to loss of data.
RxCRCErrors
Count of corrupted frames. Errors due to interference
on the serial cable.
RxGiantFrames
Count of received frames with illegal framesize. This
can occur if a frame delimiter is destroyed.
TxResets
Count of transmitter resets. Under rare circumstances
it might be necessary to reset the transmitter to work
properly.
TxAborts
Count of transmitter aborts. While sending a frame it
might be necessary to indicate this frame as aborted. In
this case the receiver regards this frame as illegal.
TxUnderruns
Count of transmitter underruns. The serial data for the
serial port is supplied too slowly.
TxGiantFrames
Count of transmitted frames with illegal
framesize. This can occur if an upper module creates
packets with more than the maximum allowed packet size.
