| cbConfTable | 1.3.6.1.4.1.9.9.185.1.1.1 | | not-accessible | This table contains configuration, control and status parameters
for performing Bit Error Rate Test (BERT) on an interface.
When cbRowStatus is 'active', ifOperStatus will be set to 'testing'. |
| cbConfEntry | 1.3.6.1.4.1.9.9.185.1.1.1.1 | | not-accessible | An entry in the BERT configuration table.
An entry is created for each interface running BERT by NMS.
The ifIndex refers to a unique value of an interface
in the ifTable on which BERT is being run.
The BERT is started or stopped as by-product of creating
and deleting entries in the cbConfTable. |
| BER cbTestPattern | 1.3.6.1.4.1.9.9.185.1.1.1.1.1 | BertPatterns | read-write | The BERT pattern to be sent and expected to be received.
An implementation may choose to support only selected patterns.
In some implementations, this object can not be modified when
the BERT is running, i.e cbRowStatus is active(1). |
| OCT cbUserPattern | 1.3.6.1.4.1.9.9.185.1.1.1.1.2 | OCTET STRING | read-write | The object used for configuring the user defined pattern
for BERT. This is the fixed repeating BERT pattern sent
and expected to be received when the cbTestPattern object is
set to 'userPattern'. The maximum length of this pattern
is 32 bits. Depending on the hardware, the patterns are
transmitted with least significant first or most
significant bit, until pattern length is reached.
This object can not be modified when the BERT is running,
i.e cbRowStatus is active(1). |
| INT cbBertTxPatternInv | 1.3.6.1.4.1.9.9.185.1.1.1.1.3 | INTEGER | read-write | This controls inversion of the transmit BERT pattern.
Possible values are :
notInverted(1): Pattern is transmitted normally.
inverted(2): Each Mark is replaced by Space and
vice versa.
For predefined BERT patterns, the value for this Object
may not be modified. An implementation may choose to
ignore the value of this object, for BERT patterns other
than 'userPattern'. When the value is ignored, the
object contains the value chosen by the underlying hardware.
This object can not be modified when the BERT is running
i.e cbRowStatus is active(1). |
| INT cbBertRxPatternInv | 1.3.6.1.4.1.9.9.185.1.1.1.1.4 | INTEGER | read-write | This controls inversion of the received BERT pattern.
Possible values are :
notInverted(1) : Pattern received is not inverted.
inverted(2) : each Mark is replaced by Space and
vice versa.
When set to inverted(1), the received data is inverted
before being processed by the pattern detector.
For predefined BERT patterns, the value for this object
may not be modified. An implementation may choose to
ignore the value of this object, for BERT patterns other
than 'userPattern'. When the value is ignored, the
object contains the value chosen by the underlying
hardware.
This object can not be modified when the BERT is running
i.e cbRowStatus is active(1). |

Possible values are:
farEndLineLoopback(1): This loopback occurs at the CPE upon
receiving a special code from the
device which initiates the loopback.
Upon receiving the loop activation request
code, the CPE enters a Line loop mode in which it
returns the entire line back to the initiator.
The CPE will continue to return the data
back to the initiator until it receives
loopback deactivation request code.
remoteLineLoopback(3): This loopback is established
at the Near-end.
In this loopback the entire line is looped back to the
Far-end with a) bit-sequence integrity maintained,
b) no change in framing, and c) no removal of bi-
polar violations.
localLoopback(3): This is also known as metallic loopback.
This loopback is used for checking the
internal circuitry of the T3/E3, T1/E1 device.
Only for physical lines.
farEndPayloadLoopback(4): This loopback occurs at the
CPE upon receiving a special code from the
device which initiates the loopback.
Upon receiving the loop activation request
code, CPE enters a Payload loop mode in which it
returns the Payload of the received data back
to the initiator.
The CPE will continue to return the data
back to the initiator until it receives
loopback deactivation request code.
remotePayloadLoopback(5): This loopback is established
at the Near-end.
In this loopback the signal that is returned to the
Far-end consists of the payload of the received signal
(with bit sequence integrity retained) and newly
generated framing information.
noLoopback(6): There is no loopback established
on the device. |
| INT cbLoopbackCode | 1.3.6.1.4.1.9.9.185.1.1.1.1.6 | INTEGER | read-write | This object specifies the type of the end device and
the type of loopback code used.
Latching Loopback: Latching Loopback is appropriate with
64 kbit/s DS0-A rate. Once invoked by a specific activation
sequence, it typically remains in effect until released by
another specific code sequence.
non-latching loopback: Non latching activation involves
continuous transmission of loopback command codes, followed
by test data interspersed with command codes.
The possible values are:
Note: The values 1 to 14 are for farEndLoopback.
cbLoopback object is farEndLoopback(1) when these values are
selected.
nonLatchOCUwithOneDevice(1): Non-latching OCU with one device.
nonLatchOCUwithChainDevices(2): Non-latching OCU with chain
of devices.
nonLatchCSU(3) : Non-latching CSU.

This loopback is based on
CCITT-ITU V.54 and is being
used to place either a single
DS0 or a DS0 Bundle(N*DS0) in
loopback mode.
lineInband(12) : This is used for loopback the
entire T1 line at the far end.
This is a repeating 5-bit
pattern(00001).
lineLoopbackESF(13): This loopback result in a full
1.544Mbit/s loopback of the
incoming signal at the far end.
The loopback is activated (latched) and
deactivated by a bit sequence defined in
ANSI T1.403 - 1995.
This corresponds to Facility Data Link
(FDL)loopbacks on a T1 channel.
This causes a repeating,16-bit ESF data
link code word(00001110 11111111) to
the remote end requesting that it
enter into a network line loopback.
localLoopback(14): This is for loop back at the
near end (facility end).
This is used to test the internals of the
device, the interface loops back the
outbound traffic from SRM to SM, back to
the SRM, hence testing the internal device
connectivity.
noLoopbackCode(15): This is for situations, where
no loopback is needed for bert tests.
One example is manual loop back at near or
far end.
payloadLoopbackESF(16): This loopback results
in 1.536 Mbit/s loopback of the payload
of the incoming signal at the far end.
The loopback is activated (latched) and
deactivated by a bit sequence defined in
ANSI T1.403 - 1995.
This corresponds to Facility Data Link
(FDL)loopbacks on a T1 channel.
This causes a repeating, 16-bit ESF data
link code word(00010100 11111111) to
the remote end requesting that it
enter into a network payload loopback.
lineLoopbackFEAC(17): Use the FEAC channel to
establish a line loopback.
smartJackInband(18): Inband loop code for SmartJack (a Telco owned
device that represents the demarcation point of T1 service),
Ref: TR-TSY-000312. |
| INT cbSingleBitErrorInsert | 1.3.6.1.4.1.9.9.185.1.1.1.1.7 | INTEGER | read-write | This object is used for inserting single bit error in the
transmitted BERT pattern.

pattern sent, in order to do sanity check on receive interface
in the event that no bit errors are detected. Injecting errors
allows users to stress communication links and to check the
functionality of error monitoring equipment along the path.
Once set to send continuous errors, errors will be inserted
at the configured rate until set to noError(1).

synchronized with the incoming sequence of patterns.
outOfSync(3) : BERT is activated, but receive is out
of synchronization with the incoming
sequence. Criteria for out of
synchronization state is defined in
ITU document O.150.
inLoopback(4): loopback establish or de-establish in
progress. The type of loopback can be
determined by cbLoopback.

on the interface. This object is valid only when
cbRowStatus is active(1). |
| INT cbDS0DPCodeIteration | 1.3.6.1.4.1.9.9.185.1.1.1.1.13 | INTEGER | read-write | Valid only with cbLoopbackCode = latchDS0Drop.
DSP-OP devices can be cross connected in the central
office in a daisy chain. By this, the user has
capability to put any of the devices in the chain in
loopback mode. A value of 1 results in no iteration
and will cause the very first device in chain to go
into loop back. A value of 2 will result into one
iteration and will cause the second device to
go into loopback and so on. This tests the channels
across multiple devices connected in a chain. |
| ROW cbRowStatus | 1.3.6.1.4.1.9.9.185.1.1.1.1.14 | RowStatus | read-write | The status of this conceptual row. This object is used for
create or modify or deleting an entry from this table.
To create a row in this table, a manager must set this
object to either createAndGo(4) or createAndWait(5).
Until instances of all corresponding columns are appropriately
configured, the value of the corresponding instance of the
cbRowStatus is notReady(3).
An entry can be deleted by setting this object to destroy(6).
STARTING BERT: Two approaches:
1. set this object to createAndGo(4) with all the mandatory
objects set to valid values.
2. Set this object to createAndWait(4). Reading this object
at this stage returns notReady(3).
Set all the other required objects with valid values.
Set this object to active(1).
STOP/RESTART BERT:
The BERT can be stopped by setting this object to
notInService(2). After setting it to notInService(2),
some parameters can be modified and BERT can be started
by setting this object to active(1).
STOP BERT:
An entry can be deleted by setting this object
to destroy(6).
Deleting an entry stops the BERT test. |
