An entry in the table. There is an entry for each available
DS1/E1 interface identified by ifType value of ds1(18).
By default, interfaces are disabled.

The entry in this table is for DS1/E1 interface which
need call related configuraton.

An entry in the DS1 current table. An entry in
this table is automatically created when a line activated.

An entry in the DS1 interval table.

An entry in the DS1 Total table.

An entry in the cds1FarEndCurrentTable.

An entry in the DS1 Far End Interval table.

An entry in the DS1 Far End Total table.

This identifies the unique threshold entry in
cds1AlarmThresholdGroupTable.
The number of entries allowed is implementation
specific.
The values set in the respective threshold objects
determine the values which when exceeded in a 15
minute or 24 hour window, will raise alarm by
generating 'cds1StatThresholdAlarm' trap.
An entry is created by setting
'cds1AlarmThresholdGroupRowStatus' to 'createAndGo(4)'
and is deleted by setting it to 'destroy(6)'.

Alarm configuration information for a particular DS1/E1
interface. The thresholds for different statistics is
identified by an entry in cds1AlarmThresholdGroupTable.
Once the thresholds configured in cds1AlarmThresholdGroupTable
are exceeded, minor or major alarms are raised depending on
the values configured in cds1StatisticalAlarmSeverity.
Triggering of an alarm is indicated by generating a trap
and also through the CLI (Command Line Interface).

An entry in the DS1 current 24 hour table. An entry is
created automatically for each DS1 interface that is
activated.
ifEntries with ifType=ds1(18) will have an entry in this
table.

An entry in DS1 previous 24 hour table.
ifEntries with ifType=ds1(18) will have an entry in
this table.

An entry in the DS1 Error Stats Table.
ifEntries with ifType=ds1(18) will have an entry in
this table.

This variable indicates  the  variety  of  DS1
Line  implementing  this  circuit.  The type of
circuit affects the number of bits  per  second
that  the circuit can reasonably carry, as well
as the interpretation of the  usage  and  error
statistics.
The reasons behind adding 'cds1Linetype' object (apart
from 'dsx1LineType' in DS1-MIB.my) for 'line type', with
enums from 'other(1)' to 'dsx2E2(11)' replicated,  are
following:
1) Addition of the two new enums (viz. 'dsx1E1Q50' and
'dsx1E1Q50CRC') in the standard DS1-MIB might not take
place in near future; that's why it was decided to
have a new object 'cds1LineType'.
2) A way was needed to be provided to configure 'line type'
from CLI (Command Line Interface) for service modules
supporting line type values from 'dsx1LineType' as well as
'cds1LineType', without having to modify two separate
parameters and at the same time, making sure that CLI
parameter values directly map to the MIB values.
Hence, enums from 'other(1)' to 'dsx2E2(11)' from object
'dsx1LineType' are replicated, and the new enums are added
as 'dsx1E1Q50(20)' and 'dsx1E1Q50CRC(21)'. The gap between
'dsx2E2(11)' and 'dsx1E1Q50(20)' provides a safe margin
in the case of modifications in 'dsx1LineType' in future;
so the CLI can still have the same enums as the standard
MIB.
It is to be noted that objects 'dsx1LineType' and
'cds1LineType' are mutually exclusive. Setting both in a
SET request (with the exception of value 'other(1)')
should result into an 'INCONSISTENT VALUE' error.
In the case of successive 'SET' requests, the value
associated with the latest request should prevail
irrespective of the object ('dsx1LineType' or
'cds1LineType') used.
Following values reflect the corresponding values
in 'dsx1LineType' object in DS1-MIB.

This object is used to enable or disable the detection
of far end loop back requests (inband or
out-of-band (ESF)).
The loopback detection is enabled by setting this object
to 'true' and loopback detection is disabled by setting
this object to 'false'. The value of this object does not
have any impact on the way dsx1LoopbackConfig object is
implemented.

This object is used to repeatedly apply the writable objects
of dsx1ConfigTable and cds1ConfigTable specified in the same
SNMP PDU starting from the row indicated by the index of the
instance for the number of rows specified in this object.
The order of operation is iterated through the logical
order of the DS1 lines. Whether the iteration will be applied
across the physical boundary or not is depended on the
system implmentation.
The GET operation on this object will always return 1.

This object is used for error checking of the operation
specified in cds1Repetition.
The value of this object is set by the SNMP manager
for its own identifier at the same time as issuing the bulk
operation by setting cds1Repetition.
Later on, the SNMP manager should check the value of this
object, if it is the same with the SNMP manager name,
then the value of cds1RepetitionResult indicates the
result of bulk operation initiated by this SNMP manager.

This object is used for error checking of the operation
specified in cds1Repetition.
This object indicates the result of bulk configuraton
initiated by the SNMP manager specified in the value of
cds1RepetitionOwner.

This object specifies whether trunk-condition is enabled.
The value 'true' means trunk-condition enable and the
value 'false'  means trunk-condition disable.
If this object is set to 'true', gateway will apply
trunk conditioning on the DS0's of this DS1 interface
that are in alarm.
Trunk Conditioning - gateway will transmit idle code pattern
for the first 2.5 secs and then transmit seized code, both
idle code and seized code are specified by the 'ds0IdleCode'
and 'ds0SeizedCode' MIB objects in the CISCO-CAS-IF-EXT-MIB.
This object is applicable for trunking applications only.

The status of this conceptual row.  This object is
used for creating, modifying and deleting entries
from cds1AlarmThresholdGroupTable.
To create a row in this table, a manager must set
this object to 'createAndGo(4)'.
An entry can be deleted by setting this object to
destroy'(6)'.
An entry in this table may be modified after
creation.
The active threshold configuration is indicated
by the object 'cds1AlarmThresholdActiveGroup'.

This variable is used to setup the severity of any of the
Statistical alarms. So when a Statistical Counter exceeds its
specified threshold, the system will send the alarm with
appropriate severity. A value of none(3) indicates that no
alarm will be raised.

This is a bitmap of the DS1 Line Statistical alarms.
A clear bitmap (i.e. no bit is set) will indicate that
no alarms are present.

This parameter specifies the increment to the Near
End alarm integration counters. The local alarms are
LOS and LOF. The integration counter is incremented by
this value every 100 ms while the alarm persists. When
the integration counter exceeds 'cds1AlarmThreshold'
an Alarm of the severity specified for the particular
alarm is declared.
The integration counter is an internal counter specific
to the implementation and dictates the slope of
integration.

This parameter specifies the decrement to the Near
End alarm integration counters. The  alarms are LOS
and LOF. The integration counter is decremented by
this value every 100 ms while no alarm persists. The
counter does not decrement below zero. When the
integration counter reaches zero any Alarm previously
declared is removed.

The value set in this object determines the value that
the alarm integration counter must reach for an near end
alarm to be declared. If the up count is 6, and the
threshold 150, an Alarm is integrated in 2.5 seconds.
If the down count is 1, then alarm will be cleared in
15 seconds.

The value of this object identifies the row in the
cds1AlarmThresholdGroupTable which contains the
threshold values for different statistics, and
is currently active.

The MIB module to describe DS1/E1 interface objects. This is
an extension to the standard DS1/E1 MIB (RFC 2495).
Unless mentioned, the DS1 interface refers to both
T1/E1 interfaces.
Terminology ( Taken From RFC2495)
AIS - Alarm Indication Signal
LOS - Loss Of Signal
LOF - Loss Of Frame
Yellow Alarm - Far End LOF.
Red Alarm    - Near End LOF.
BPV - Bipolar Violation for an AMI-coded signal is the
occurrence of a pulse of the same polarity as the
previous pulse.
A BPV error event for a B8ZS- or HDB3- coded signal
is the occurrence of a pulse of the same polarity as
the previous pulse without being part of the zero
substitution code. (See TR-TSV-000773 Section 3.5.1.1)
EXZ - An Excessive Zeroes error event for an AMI-coded
signal is the occurrence of more than fifteen
contiguous zeroes. For a B8ZS coded signal,
the defect occurs when more than seven contiguous
zeroes are detected.
LCV - Line Coding Violation is the occurrence of either
Bipolar Violation (BPV) or Excessive Zeroes (EXZ)
error event.
PCV - A Path Coding Violation error event is a frame
synchronization bit error in the D4 and E1-noCRC formats,
or a CRC or frame synch. bit error in the ESF and E1-CRC
formats. (Also known as CV-P; See T1.231 Section 6.5.2.1)
CS - A Controlled Slip is the replication or deletion of the
payload bits of a DS1 frame. (See T1.231 Section 6.1.1.2.3)
A Controlled Slip may be performed when there is a
difference between the timing of a synchronous
receiving terminal and the received signal.  A Controlled
Slip does not cause an Out of Frame defect.
LES  - Line Errored Seconds. A LES is a second in which one or
more LCV error events are detected. (See TR-TSV-000773
Section 3.5.1.1)
ES   - Errored Seconds (ES). For ESF and E1-CRC links an ES
is a second with one or more PCV or one or more OOF
defects OR one or more CS events OR a detected AIS
defect. (See TR-TSV-000773 Section 3.5.1.1)
For D4 and EN-noCRC links, the presence of BPVs also
triggers an ES.
This is not incremented during an UAS.
BES  - Bursty Errored Seconds. A BES is a second with fewer
than 1 PCV error events, no Severely Errored Frame
defects and no detected incoming AIS defects. The
CS are not included in this parameter.
This is not incremented during an UAS. It applies to
ESF signals only.
SES  - Severely Errored Seconds. A SES for ESF signals is a
second with 320 or more PCV error events OR one or
more OOF defects OR a detected AIS defect.
(See TR-TSV-000773 Section 3.5.1.1)
For E1-CRC signals, a SES is a second with 832 or
PCV error events OR one or more OOF defects.
For E1-noCRC signals, a SES is a 2048 LCVs or more.
For D4 signals, a SES is a count of one second
intervals with Framing Error events, or an OOF defect,
or 1544 LCVs or more.
SEFS - Severely Errored Framing Second. An SESF is a second
with one or more OOF defects OR a detected AIS defect.
(Also known as SAS-P (SEF/AIS second).
(See TR-TSV-000773 Section 3.5.1.1)
DM   - Degraded Minutes. A DM is one in which the estimated
error rate exceeds 1E-6 but does not exceed 1E-3.
UAS  - Unavailable Seconds. The UAS are calculated by counting
the number of seconds that the interface is unavailable.
CSS  - Controlled Slip Seconds. A CSS is a one-second interval
containing one or more controlled slips. This is not
incremented during an Unavailable Second.
LSES - Line Severely Errored Seconds is defined as a count of
1-second intervals with 1544 Bipolar Violations plus
Excessive Zeros event or one or more LOS defects.
PSAS - Path SEF/AIS (PSAS) encountered.
