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: |
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. Range: 0 to 255 |
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: |
CRCMode |
The type of CRC checksum of the HDLC frames. crc16(1) 16 Bit CRC crc32(2) 32 Bit CRC Enumerations: |
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. |
