| C32 xgcpInBadVersionsEx | 1.3.6.1.3.90.1.1.1 | Counter32 | read-only | The total number of incoming messages which were delivered to
the protocol entity and were for an unsupported protocol
version. |
| I32 xgcpRequestTimeOut | 1.3.6.1.3.90.1.1.2 | Integer32 | read-write | The request timeout is used to determine the timeout value used
for retransmitting unacknowledged message.
It is the responsibility of the requesting entity to provide
suitable timeouts for all outstanding commands, and to retry
commands when timeouts exceeded.
The default value of this object is 500 milliseconds. |
| I32 xgcpRequestRetries | 1.3.6.1.3.90.1.1.3 | Integer32 | read-write | This object specifies the number of retries for a request that
exceeds timeout.
It is the responsibility of the requesting entity to provide
suitable timeouts for all outstanding commands, and to retry
when times out.
The default value of this object is 3. |
| INT xgcpAdminStatus | 1.3.6.1.3.90.1.1.4 | INTEGER | read-write | The desired state of the protocol entity.
The possible admin status are:
up - bring up protocol entity administratively
down - bring down protocol entity adiministratively
gracefulDown - gracefully shut down protocol entity
administratively.
A graceful shutdown indicates that the protocol
will be taken out of service after the restart
delay timer timeouts or all connections are torn down.
When in graceDown, the xgcpOperStatus goes from up to
down via shutDownInProgress.
If there is no connection or restart delay timer
timeouts then xgcpOperStatus moves from
shutDownInProgress to down. |
| INT xgcpOperStatus | 1.3.6.1.3.90.1.1.5 | INTEGER | read-only | This object indicates the current operational
status of the protocol entity.
The possible operating status are:
up - protocol up
down - protocol down
shutDownInProgress - Shut down in progress.
The operating status - shutDownInProgress indicates
that the Media Gateway is in a transition state from
up to down. This state happens when resources are in
the process of being cleaned up and new resource
can't be allocated. |
| C32 xgcpUnRecognizedPackets | 1.3.6.1.3.90.1.1.6 | Counter32 | read-only | This refers to the count of unrecognized packets
since reset. |

XGCP statistics are kept in this table, with each
table entry containing the statistics of XGCP that
communicates with a Media Gateway Controller (MGC) at
a specific IP address of the MGC.
Each table entry is composed of the following information:
1) Messages successfully received/transmitted per IP device
2) Messages failed to be received/transmitted per IP device |
| xgcpMsgStatEntry | 1.3.6.1.3.90.1.1.7.1 | | not-accessible | The row of the xgcpMsgStatTable contains
information about XGCP message statistics per IP address
of the Media Gateway Controller.
An entry is created when a request messge with new IP
address is received from Medida Gateway Controller.

that communicate with the Media Gateway Controller on
that IP address.
Successful messages apply to both transmit and
receive messages.
Transmit: Positive ACK is received from the Media
Gateway Controller
Receive: Positive ACK is sent to the Media Gateway
Controller. This implies that the format
of the message is correct and the request
can be fulfilled. |
| C32 xgcpFailMessages | 1.3.6.1.3.90.1.1.7.1.3 | Counter32 | read-only | This object specifies the count of failed messages
that communicate with the Media Gateway Controller on
that IP address.

messages.
Transmit: Either NAK is received from the MGC or message
times out waiting for ACK.
Receive: Format of the received message is bad or
the request can not be fulfilled. |
| xgcpExtensionObjects | 1.3.6.1.3.90.1.2 | | | |
| I32 xgcpRestartInProgressMWD | 1.3.6.1.3.90.1.2.1 | Integer32 | read-write | The maximum waiting delay (MWD) timeout value is used for the
Media Gateway to send the Restart In Progress to the Media
Gateway Controller.
The default value of this object is chosen in an
implementation-dependent manner by the MGCP functionality
based on the call volume of the system. |
| I32 xgcpRestartDelay | 1.3.6.1.3.90.1.2.2 | Integer32 | read-write | This object specifies the Restart Delay Timeout for
the restart process.

| I32 xgcpLowerBoundForPacketLoss | 1.3.6.1.3.90.1.4.1 | Integer32 | read-write | This object specifies the lower bound for voice
quality packet loss per 100,000 packets. Voice quality
packet loss may happen due to network congestion or due
to network overload.
When packet loss(number of packet per 100,000) is high
enough to reach lower bound(e.g. 1500) and then higher
bound(e.g. 2500) the first time, a MGCP/SGCP Notify
message is sent to the Media Gateway Controller.
Subsequent hits of the higher bound results in a
MGCP/SGCP Notify message being sent to the Media Gateway
Controller only after the lower bound is hit.

| I32 xgcpLowerBoundForJitter | 1.3.6.1.3.90.1.4.3 | Integer32 | read-write | This object is the lower bound for Quality Alert for
Jitter.
Jitter is an estimate of the statistical variance of the RTP
data packet interval-rival time measured in milliseconds and
expressed as an unsigned integer.
When jitter(milliseconds) is long enough to reach lower
bound(e.g.30 ) and then higher bound(e.g. 150) the first
time, a MGCP/SGCP Notify message is sent to the Media
Gateway Controller.
Subsequent hits of the higher bound results in a
MGCP/SGCP Notify message being sent to the Media Gateway
Controller only after the lower bound is hit.
The default value of this object is 30. |
| I32 xgcpHigherBoundForJitter | 1.3.6.1.3.90.1.4.4 | Integer32 | read-write | This object is the higher bound for Quality Alert for
Jitter.

| I32 xgcpLowerBoundForLatency | 1.3.6.1.3.90.1.4.5 | Integer32 | read-write | This object is the higher bound for Quality Alert for
latency.
QA latency is an estimate of the network delay, expressed
in milliseconds. This is the average value of the difference
between the Network Time Protocol (NTP) timestamp indicated
by the senders of the RTCP messages and the NTP timestamp
of the receivers, measured when these messages are received.
When latency (milliseconds) is long enough to reach lower
bound (e.g.150 ) and then higher bound(e.g. 300) the first
time, a MGCP/SGCP Notify message is sent to the Media
Gateway Controller.
Subsequent hits of the higher bound results in a
MGCP/SGCP Notify message being sent to the Media Gateway
Controller only after the lower bound is hit.
The default value of this object is 150. |
| I32 xgcpHigherBoundForLatency | 1.3.6.1.3.90.1.4.6 | Integer32 | read-write | This object is the higher bound for Quality Alert for
latency.
QA latency is an estimate of the network delay, expressed
in milliseconds. This is the average value of the difference
between the NTP timestamp indicated by the senders of the
RTCP messages and the NTP timestamp of the receivers,
measured when these messages are received.
The default value of this object is 300. |
| xgcpDefaultMGCObjects | 1.3.6.1.3.90.1.5 | | | |
| STR xgcpMGCCfgAddress | 1.3.6.1.3.90.1.5.1 | DisplayString | read-write | This object is used to configure either the domain
name or the IP address of the Default Media Gateway
Controller in standard dot notation.
The complete address of a default MGC is cmposed of
IP address/Domain Name and UDP port.
xgcpMGCCfgaddress specifies address of the default Media
Gateway Controller to which RSIP(RestartInProgress) message
is sent whenever system starts up or line goes up.
If DNS name is entered and the IP address is found,
MG will send RSIP to the desired MGC. If no IP address is
found or no such DNS name exists, no RSIP will be sent.
If IP address is entered, MG will send RSIP to that address.
If there is no response, it could be that the network is down
or user misconfigures the address (IP address, Domain Name or
UDP port number) |
| I32 xgcpMGCCfgUDPPort | 1.3.6.1.3.90.1.5.2 | Integer32 | read-write | This object is used to configure the UDP port
of the Media Gateway Controller.
The UDP port is used together with xgcpMGCCfgAddress to
specify the destination address of the default Media
Gateway Controller to which RSIP message is sent when
system starts up or line goes up. |
| INT xgcpMGCCfgConnStatus | 1.3.6.1.3.90.1.5.3 | INTEGER | read-only | This object is used to specify the connection status
of the Default Media Gateway Controller.
When sending RSIP to default Media Gateway Controller,
there could be the following status:
unknown - undefined stauts.
connected - RSIP sent and response to it is received.
connecting - RSIP is sent and waiting for response.
unknownName - no domain name/ip address is found
when checking the DNS for the domain name
entered in xgcpMGCCfgAddress. No RSIP
message is sent.
noResponse - timeout on RSIP message.
The possible casues for no response on RSIP message:
1) Address(IP Address/Domain Name and UDP) for the default
MGC is correct but MGC in not up or network is down.
2) MGC is up but at a different address (IP Address/
Domain Name)
3) MGC is up and at the same address(IP address/
Domain Name) but wrong UDP port.
4) MGC is down and address is wrong. |
