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.
