Index
Unique index of the X21 interface.
L1State
The X21 physical layer state
dn(1)		physical layer is inactive;
up(2)		physical layer is active;
Enumerations:
  • dn (1)
  • up (2)
L1Mode
The physical layer (layer 1) mode. When configured as
DCE(2) the X21 interface provides the clock.
Enumerations:
  • dte (1)
  • dce (2)
IfLeads
The value of IfLeads has influence on the state of the
physical layer (L1State). When configured as
IfLeads=enabled(1), the state of the physical layer
depends on the signals of the X.21 interface pins
`Indication' and `Control'. When configured as
IfLeads=disabled(2), the state of the physical layer
stays always up.
Enumerations:
  • enabled (1)
  • disabled (2)
Speed
The X21 interface speed in bits per second. The range
can be configured between 2Mbits and 2400 Bits per
second.
Enumerations:
  • s2048k (1)
  • s1024k (2)
  • s512k (3)
  • s256k (4)
  • s128k (5)
  • s64000 (6)
  • s38400 (7)
  • s19200 (8)
  • s14400 (9)
  • s9600 (10)
  • s2400 (11)
L2Mode
The layer 2 mode. This value has influence on the
HDLC address field (first byte of a HDCL frame). When
configured as DTE(1) the address in a command frame is
0x01, when configured as DCE(2) it is 0x03. For
response frames it is vice versa. When configured as
AUTO(3), layer 2 is set to the same mode like L1Mode is
set.
Enumerations:
  • dte (1)
  • dce (2)
  • auto (3)
SpeedReal
The measured X21 interface speed in bits per second.
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 X21 card is unable
to grant sufficiently soon/often the bus, the
32-character RxFIFO may fill up. This leads to loss of
data.
RxCRCErrors
Count of corrupted frames. Errors due to interference
on the X21 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
X21 card 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.
IfReSyncs
Count of interface resynchronization. Under rare
circumstances it might be necessary to resynchronize
the physical interface to work properly.
Bundle
Index of the bundle to aggregate multiple Channels
to one interface.
