"Each entry represents the association of a SONET/SDH path or

applicable PW entry in the pwTable.
An entry is created in this table by the agent for every
entry in the pwTable with a pwType equal to 'cep'.
All read-write objects in this table MAY be changed at any
time; however, change of some objects (for example
pwCepCfgIndex) during PW forwarding state may cause
traffic disruption.
Manual entries in this table SHOULD be preserved after a
reboot. The agent MUST ensure the integrity of those
entries. If the set of entries of a specific row are found
to be inconsistent after reboot, the PW pwOperStatus MUST
be declared as notPresent(5)."

'timeslotInUse'(1) is set when another CEP PW has already
reserved a timeslot (or timeslots) that this CEP PW is
attempting to reserve.
'timeslotMisuse'(2) is set when the stated timeslot this
PW is trying to use is not legal, for example, if
specifying a starting timeslot of 45 for a SONET path of
an STS-12c width.
The peerZZZIncompatible bits are set if the local
configuration is not compatible with the peer configuration
as available from the CEP option received from the peer
through the signaling process and the local node cannot
support such asymmetric configuration.
The peerZZZAsymmetric bits are set if the local
configuration is not compatible with the peer configuration
as available from the CEP option received from the peer
through the signaling process, but the local node can
support such asymmetric configuration."

DESCRIPTION
"Definitions:
'missingPkt'(0) - While playing out a sequence of packets,
at least one packet was determined to be missing based on a
gap in the CEP sequence number. Note: If the implementation
supports packet reordering, detecting gaps SHOULD take
place as they are played out, not as they arrive. This
provides time for misordered packets to arrive late.
'ooRngDropped'(1) - At least one packet arrived outside the
range of the jitter buffer. This may be because the
jitter buffer is full or the sequence number addresses
a buffer outside the current jitter buffer range or
an already occupied buffer within range. Whether or not
packet reordering is supported by the implementation, this
indication MUST be supported.
'jtrBfrUnder'(2) - The jitter buffer underflowed because
not enough packets arrived as packets were being
played out.
'pktMalformed'(3) - Any error related to unexpected
packet format (except bad header stack) or unexpected
length.
'lops'(4) - Loss of Packet Synchronization.
'cepRdi'(5) - Circuit Emulation over Packet Remote Defect
Indication. Remote Defect Indication (RDI) is generated by
the remote CEP de-packetizer when LOPS is detected.
'cepAis'(6) - Remote CEP packetizer has detected an Alarm
Indication Signal (AIS) on its incoming SONET stream.
cepAis MUST NOT (in itself) cause a CEP PW down
notification.
'badHdrStack'(7) - Set when the number of
CEP header extensions detected in incoming packets does
not match the expected number.
'cepNeFailure'(8) - Set when CEP-NE failure is currently
declared.
'cepFeFailure'(8) - Set when CEP-FE failure is currently
declared.
This object MUST hold the accumulated indications until the
next SNMP write that clear the indication(s).
Writing a non-zero value MUST fail.
Currently, there is no hierarchy of CEP defects.
The algorithm used to capture these indications
is implementation specific."

DESCRIPTION
"This object contains an appropriate value to be used
for pwCepCfgIndex when creating entries in the
pwCepCfgTable. The value 0 indicates that no
unassigned entries are available. To obtain the
value of pwCepCfgIndex for a new entry in the
pwCepCfgTable, the manager issues a management
protocol retrieval operation to obtain the current
value of pwCepCfgIndex. After each retrieval
operation, the agent should modify the value to
reflect the next unassigned index. After a manager
retrieves a value, the agent will determine through
its local policy when this index value will be made

DESCRIPTION
"These parameters define the characteristics of a

pwCepCfgRowStatus MUST be set to notInService(2).
The agent MUST NOT allow the change of the
pwCepCfgRowStatus from the active(1) state for
pwCepCfgEntry, which is in use by at least one active PW.
Manual entries in this table SHOULD be preserved after a
reboot, the agent MUST ensure the integrity of those

SYNTAX Unsigned32
MAX-ACCESS read-create
STATUS current
DESCRIPTION
"The number of SONET bytes of the Path or VT carried as
payload within one packet. For example, for STS-1/VC-3 SPE
circuits, a value of 783 bytes indicates that each packet
carries the payload equivalent to one frame. For VT1.5/VC11
circuits, a payload length of 104 bytes indicates that each
packet carries payload equivalent to one VT1.5 super-frame.
The actual payload size may be different due to bandwidth
reduction modes, e.g., Dynamic Bandwidth Allocation (DBA)
mode or dynamically assigned fractional SPE. This length
applies to inbound and outbound packets carrying user
payload. Although there is no control over inbound packets,
those of illegal length are discarded and accounted for (see
pwCepPerf...Malformed.)
The default values are determined by the pwCepType:
783 for pwCepType equal to spe(2) or fracSpe(3).
For vt(3) modes, the applicable super-frame payload size
is the default value."

It applies to CEP's bandwidth-savings packets. Currently,
DBA is the only bandwidth-savings packet type (in the
future, CEP may support compression). Minimum packet
length is necessary in some systems or networks.
Setting zero here indicates that there is no minimum
packet restriction."

DESCRIPTION
"This object defines if reordering is applied for incoming

If set 'true', as inbound packets are queued in the
jitter buffer, out-of-order packets are reordered. The
maximum sequence number differential (i.e., the range in
which resequencing can occur) is dependant on the depth
of the jitter buffer.
If the local agent supports packet reordering, the default
value SHOULD be set to 'true'; otherwise, this value
SHOULD be set to 'false'."
::= { pwCepCfgEntry 4 }
pwCepCfgEnableDBA OBJECT-TYPE
SYNTAX BITS {
ais (0),
unequipped (1)
}
MAX-ACCESS read-create
STATUS current
DESCRIPTION
"This object defines when DBA is applied for packets sent
toward the PSN.
Setting 'ais' MUST cause CEP packet payload suppression
when AIS is detected on the associated SONET path.
Similarly, 'unequipped' MUST cause payload suppression
when an unequipped condition is detected on the SONET/SDH
PATH/VT.
During DBA condition, CEP packets will continue
to be sent, but with indicators set in the CEP header
instructing the remote to play all ones (for AIS) or all
zeros (for unequipped) onto its SONET/SDH path.
NOTE: Some implementations may not support this feature.
In these cases, this object should be read-only."

DESCRIPTION
"vtgMapEbmConflict(1) is set when the configured static EBM
does not match the configured vtgMap for fractional
STS-1/VC-3 circuits or when the TUG2Map is in conflict with
the static EBM for VC-4 circuits, for example, if the vtgMap
specifies that VTG#1 carries VT2 VTs while the EBM indicate
that four VTs are equipped within VTG#1.
vtgMapAsyncConflict(2) is set when there is a conflict
between the mode, the async indication, and the vtgMap
fields. For example, fractional mode is set to staticAsync
while the VtgMap indicates that the STS-1/VC-3 carries VTs,
or both async1 and Tug2Map are set in fractional VC-4
circuits."

STATUS current
DESCRIPTION
"CEP bridges the SONET and packet worlds. In the packet
world, counts typically start from the time of service
creation and do not stop. In the SONET world, counts are
kept in 15-minute intervals. The PW CEP MIB supports both
methods. The current 15-minute interval counts are in
this table. The interval and total stats are in tables
following this.
This table provides per-CEP PW performance information.
High capacity (HC) counters are required for some counts
due to the high speeds expected with CEP services. A SONET
path of width 48 (STS-48c) can rollover non-HC counters in
a few minutes."
