Index
The unique interface index of the e3/ds3 interface.
Type
The e3 physical interface type

off(1)		interface is switched offline and the 

line interface unit is switched off.

e3-unframed(2) Synchronous 34.368 MBit/s fullduplex,

with HDB3 line coding.

ds3-unframed(3) Synchronous 44.736 MBit/s fullduplex,

with B3ZS line coding.

sts1-unframed(4) Synchronous 51.840 MBit/s fullduplex,

with B3ZS line coding.

Enumerations:
  • off (1)
  • e3-unframed (2)
  • ds3-unframed (3)
  • sts1-unframed (4)
Clock
The clock source of the E3/DS3 connection.

intern(1)	Your router provides the master clock

of the E3/DS3 connection.

extern(2)	Your telephone company or the remote

DSU provides the master clock of the 

E3/DS3 connection.

extern-preferred(3) The same like 'extern'.
Enumerations:
  • intern (1)
  • extern (2)
  • extern-preferred (3)
L2Mode
The X.75 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 according to the e3IfClock setting.

dte(1)	HDLC address 0x01

dce(2)	HDLC address 0x03

auto(3)	= DCE if e3IfClock is set to intern,

= DTE otherwise

Enumerations:
  • dte (1)
  • dce (2)
  • auto (3)
TestPattern
This variable configures which test pattern should be

transmitted.

normal(1)	normal data, no test pattern is transmitted.

ones(2) 	Transmit unframed all ones.

alt-0-1(3)	Transmit unframed 101010... pattern in

E3 mode and transmit AIS in DS3 mode.

prbs(4)		Transmit PRBS pattern per ITU O.151.

In E3 mode 2^23 -1 PRBS pattern is used.

In DS3 mode 2^15 -1 PRBS pattern is used.

Enumerations:
  • normal (1)
  • ones (2)
  • alt-0-1 (3)
  • prbs (4)
Loopback
This variable represents the loopback configuration

of the E3/DS3 interface.

noloop(1)	No loopback is configured, normal data

is transmitted and received.

remoteloop(2)	The received data is transmitted again.

Receiving works normal.

localloop(3)	The transmitted data is received

Transmitting works normal.
Enumerations:
  • noloop (1)
  • remoteloop (2)
  • localloop (3)
Bundle
Index of the bundle to aggregate the interface and 

channels of other interfaces

to one interface.
CableLength
'short' should be used for a cable lenght less then 225 feet.

'long' should be used otherwise. With 'short' the Tx signal is 

preattenutated similar to the attenuation of 225 feet 

coaxial cable. The setting has no effect in E3 mode
Enumerations:
  • short (1)
  • long (2)
CRCMode
The type of CRC checksum of the HDLC frames.

crc16(1)	16 Bit CRC 

crc32(2)	32 Bit CRC
Enumerations:
  • crc16 (1)
  • crc32 (2)
L1State
The e3 physical layer state

down(1)	physical layer is inactive

up(2)		physical layer is active

prbs(3)	physical layer is active, a PRBS signal

is detected

nolicense(4)  a license must be configured to activate

the interface.
Enumerations:
  • down (1)
  • up (2)
  • prbs (3)
  • nolicense (4)
RxPackets
Count of received valid HDLC Frames.
RxOctets
Count of received bytes.
TxPackets
Count of transmitted valid HDLC 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 e3 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 e3 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 e3 data for the

e3 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.
