for the Type Of Service (TOS) octet for cells carrying
VoIP bearer (RTP) traffic. The first 3 bits denotes
the precedence while the other bits denotes the TOS.

the other endpoint. In the case of switching application,
the CAS bits are backhauled to the Call Agent through
xGCP-CAS protocol.

value is 'true(1)', else the default value is 'false(2)'. |

Before establishing the connection, endpoints on either
VISM's should have been created and the line signaling
type needs to be configured. |

| INT vismRtpFailReason | 1.3.6.1.4.1.351.150.20.1.1.1.1.20 | INTEGER | read-only | This object is used to indicate the RTP failure
reason.
'self' : fail because of non-PVC alarm.
'highLevel' : fail because of PVC alarm.
'both' : fail because of both PVC and non-PVC alarm.
'notFail' : no failure. |
| T/F vismRtpICSEnable | 1.3.6.1.4.1.351.150.20.1.1.1.1.16 | TruthValue | read-create | This attribute is used to enable or disable the ICS(Idle
Channel Suppression) for a connection. This can be
specified while adding the connection and cannot be
modified.
When the ICS is enabled the DSP will look for the idle
CAS (ABCD bits) pattern specified in ds0IdleCode in
dsx0 MIB. If the idle pattern is present the DSP stops
generating voice packets towards network side. By default
the ds0IdleCode will be zero unless the user has configured
it before adding the cid. If the ds0IdleCode is changed
after the connection is added it will have no affect
unless the card is reset. |
| U32 vismRtpInterArrivalJitter | 1.3.6.1.4.1.351.150.20.1.2.1.1.7 | Unsigned32 | read-only | This object provides the average interarrival jitter

terminating end and back. |
| INT vismRtpLcn | 1.3.6.1.4.1.351.150.20.1.1.1.1.19 | INTEGER | read-only | This object is used to indicate the RTP related

PVC (Permanent virtual circuit) is used for this
object. |
| I32 vismRtpLocPort | 1.3.6.1.4.1.351.150.20.1.1.1.1.3 | Integer32 | read-create | This object determines the static local RTP port (UDP)
that this connection is using. Only even numbers
are allowed as odd numbers are used for RTCP(Real-time
transport control protocol) port. The local RTP port
has to be unique as only one connection is allowed
per port. |

adding connection(s) in VoIP Trunking.
IANA (Internet assigned number Authority) values (0..95)
are static payload and (96..127) are dynamic payload type.
The values (128..255) are define here to accomodate
any future extension, also 256 is chosen as a default
value to avoid payload conflict bewteen gateways.
The value of 256 indicate the DSP should use a
assigned payload value for the codec. |
| INT vismRtpPktPeriod | 1.3.6.1.4.1.351.150.20.1.1.1.1.9 | INTEGER | read-create | This object gives the packetization period for a

| IP vismRtpRmtIp | 1.3.6.1.4.1.351.150.20.1.1.1.1.4 | IpAddress | read-create | This object determines the remote VISM's IP address.
For every RTP connection the remote port and remote IP
pair needs to be unique. |
| I32 vismRtpRmtPort | 1.3.6.1.4.1.351.150.20.1.1.1.1.5 | Integer32 | read-create | This object determines the static remote RTP port (UDP)
that this connection is using. Only even numbers are
allowed as odd numbers are used for RTCP port.
The combination of remote ip and remote port needs
to be unique for a connection. |
| ROW vismRtpRowStatus | 1.3.6.1.4.1.351.150.20.1.1.1.1.18 | RowStatus | read-create | This object is used to create, modify or delete an entry.
An entry can be created using the 'createAndGo' option.
Before creating a RTP connection, the endpoint should
have already been created. And the line signaling type
should have been configured.
For creating a RTP connection, vismRtpEndptNum,
vismRtpLocPort, vismRtpRmtPort, vismRtpRmtIp and
vismRtpCodecType need to be provided. For the other
objects the default will be applied.
The RowStatus would be set to 'active' by the agent
while creating a RTP connection.
While deleting a RTP connection the RowStaus will be
set to 'destroy'. The RTP connection won't be deleted
if there are still call going on the connection. |
| T/F vismRtpTriRedundancy | 1.3.6.1.4.1.351.150.20.1.1.1.1.12 | TruthValue | read-create | This object tells whether the packets need to be sent
in triplicates or not. If it is set to 'true(1)' the
packets will be sent three times else will only be sent
once (this is used for reliable links to save bandwidth).
This object will override the card level object
configuration vismVoIpTripleRedundancy(defined in
CISCO-VISM-MODULE-MIB MIB).
The default value is 'true(1)' if vismRtpDtmfTransport
or vismRtpCasTransport is true, else 'false(2)'. |
| T/F vismRtpVad | 1.3.6.1.4.1.351.150.20.1.1.1.1.15 | TruthValue | read-create | This attribute defines whether the VAD has to be
applied on this channel, upon detection of silence.
For algorithms that do not have VAD standards,
Cisco-proprietary VAD can be applied and the
generic SID (Silence Information Descriptor) packet
as specified in I.366.2 standards can be sent to the
other end.
When the codecType is clearChannel VAD has to be off. |
| I32 vismRtpVadTimer | 1.3.6.1.4.1.351.150.20.1.1.1.1.10 | Integer32 | read-create | This attribute defines the hangover time for VAD
(Voice Activity Detection) in milliseconds. Once
the voice inactivity is detected, the gateway will
wait for this duration before activating silence
suppression. |
