CISCO-DSP-MGMT-MIB: View SNMP OID List / Download MIB

Digital Signal Processing (DSP) Management MIB module. The MIB module monitors the DSP resource and status. Acronyms & Terms ================ DTMF - Dual Tone Multi-Frequency. DTMF uses two frequencies, the high frequency omponent and the low frequency component, to generate digit signals. DSPFarm - DSPFarm ia a logical name given to a functionality which groups the DSP resources to provide certain service like transcoding and conferencing using DSP. DSPFarm profile - A DSPFarm profile logically groups the DSP to perform service like transcoding and conferencing. It is uniquely identified by a profile number. MTP - Media Termination Point. RTP packet received by MTP in the incoming call leg will be regenerated and send out through the outgoing call leg. transcode - Translating codec. transcoder is used to do codec translation. If incoming call leg negotiates codec-A and outgoing call leg negotiates codec-B then transcoder will convert received RTP packet from codec-A to codec-B or codec-B to codec-A. MTP hardware session - Media termination functionality with using DSP. MTP software session - Media termination functionality without using DSP. RTP - Real-time Transport protocol. Video Pool - A group of DSP resources dedicated to providing video services.

The DSP Card Table. It contains status information of the DSP cards present within the router.

An entry in the DSP card table indicates the DSP card state, resource utilization. Each entry is created when a DSP software is detected on a DSP card. The entry is deleted when the DSP card is deleted.

The object corresponds to cardIndex in the chassis mib. If value of this object is 0, then the entry is not associated to cardIndex of the chassis mib.

The object indicates the current state of DSP card being monitored. normal - DSP card in normal condition. warning - DSP card has some problem and need attention. critical - DSP card has a major alarm. fatal - DSP card is not functional. DSP subsystem might reset DSP card to recover it from the fatal error condition. After the DSP card is reset successfully, the object cdspCardResourceUtilization and cdspCardLastHiWaterUtilization are reset to 0. If the fatal error is persistent in this object after card is reset, the card should be replaced. offLine - DSP card is in off-line maintenance state. Enumeration: 'fatal': 4, 'offLine': 5, 'warning': 2, 'critical': 3, 'normal': 1.

The object indicates the percentage of current DSP video resource pool utilization of the card.

This object specifies the threshold of DSP video pool resource usage. When cdspCardVideoPoolUtilization crosses the value of this threshold in the rising direction, cdspVideoUsageNotification is generated. If cdspCardVideoPoolUtilization stays above the value of this threshold, cdspVideoUsageNotification is generated whenever the value of cdspCardVideoPoolUtilization increases, but no notification is sent if when the value of cdspCardVideoPoolUtilization decreases. No notification is sent if cdspCardVideoPoolUtilization crosses the value of this threshold in the falling direction.

Status information for the DSPs. This status table is used for tracking dangling DSP resources. The dangling DSP channel means that the DSP channel is reserved for serving calls but the channel is not used by active calls. The number of the dangling DSP channels can be computed by 'cdspInUseChannels - cdspActiveChannels'.

An entry in cdspStatusTable indicates the DSP state and alarm conditions. Each entry is created when a DSP is detected on a DSP card. The entry is deleted when the DSP card is deleted. The 'entPhysicalIndex' represents a DSP entity, and the 'entPhysicalClass' is 'other(1)'.

This table contains information on voice call setup related parameters for DSP resource.

An entry in the DSP table contains information regarding a single DSP resource associated voice call setup parameters. An entry in this table is created when a DSP is detected and the DSP resource can be used by voice applications. An entry in this table is deleted when the DSP associated card/module is removed from the system. The 'entPhysicalClass' for the entry is 'other'.

This object specifies the RTP (Real Time Protocol) payload type of the SID (Silence Insertion Descriptor) packet that is sent to the remote endpoint at the onset of silence suppression. Enumeration: 'decimal': 13, 'hexadecimal': 19.

This objects controls if RTCP (Real Time Control Protocol) will be enabled. If this object is set to 'true', both transmission and reception of RTCP packets are enabled; otherwise, transmission of RTCP packets is disabled while any received RTCP packets are ignored.

This attribute specifies the RTCP report interval (defined in RFC1889). It indicates the interval in which the RTCP reports should be sent to the participating members. RTCP reports is sent out in a random interval computed by using 'cdspRtcpTransInterval' and a random number that is between 0.5 and 1.5. This interval timer also serves the purpose of RTP packets receive timer. At every interval multiplier times this interval, where a check is made on a VoIP connection (which is in SENDRECV or RECVONLY xGCP modes) to see if any RTP packets have been received. If not, gateway-initiated DLCX should be sent to the Call Agent. This object is applicable only if 'cdspRtcpControl' is set to 'true'.

This object specifies an approximate RTCP report interval (defined in RFC 1889) in milliseconds in which the RTCP reports should be sent to the participating members. It specifies how many times the RTCP reports may fail before exception condition activity may be done. In the time elapse of value of this MIB object times the RTCP Report Interval specified by 'cdspRtcpTransInterval', a check will be done on a VoIP connection (which is in SENDRECV or RECVONLY xGCP modes) to see if any RTP packets have been received. If not, gateway-initiated DLCX should be sent to the Call Agent. This object is applicable only if 'cdspRtcpControl' is set to 'true'.

This attribute is used to enable or disable the Adaptive VAD knob of the VAD algorithm. Adaptive VAD works in conjunction with VAD Threshold (cvifcfgMusicOnHoldThreshold from CISCO-VOICE-IF-MIB). When this object set to 'true', VAD Threshold is ignored and the DSP adjusts the threshold automatically according to the background noise level. When the adaptive VAD configuration is 'false', VAD threshold is used directly. The VAD configuration is ignored for all CODECs that contain their own VAD (G.729AB, G.723.1A and GSM-EFR). Likewise, when a channel is configured in ClearChannel mode (Clear Channel is Non-Compression CODEC channel), VAD will automatically be disabled irrespective of the configuration.

This object specifies the power level of the low frequency component of DTMF. The power level of the high frequency component of DTMF is relative above or below the value specified in object cdspDtmfPowerTwist. If the value of cdspDtmfPowerTwist is 0, the power level of the high frequency component as well as the low frequency component is specified by this object.

This object specifies the relative power level of the high frequency component of DTMF. The low frequency group is always fixed to the value specified by cdspDtmfPowerLevel. When this object is set to 0, the power level of both frequency components is set to the same level. When this object is set to a positive value, the power level of the high frequency component is set to relatively higher specified in this object than the low frequency component. For example if cdspDtmfPowerLevel is set to -120(-12 dBm) and this object is set to 50, the power level of the high frequency component becomes -70(-7 dBm). When this object is set to a negative value, the power level of the high frequency component is set to relatively lower specified in this object than the low frequency component. For example if cdspDtmfPowerLevel is set to -120(-12 dBm) and this object is set to -100, the power level of the high frequency component becomes -220(-22 dBm). The power level of the high frequency component has to be in the data range specified in cdspDtmfPowerLevel. For example if cdspDtmfPowerLevel is set to -200(-20 dBm) and this object is set to -100, the power level of the high frequency component will become -300(-30 dBm) which is out of the range (-250..30) of data specified in cdspDtmfPowerLevel, so -100 is illegitimate for this setting.

This object specifies when the RTCP receive timer is started. disabled - timer is disabled startImmediately - timer starts immediately as soon as RTCP is enabled on the call startRtpOrRtcpPktRcvd - timer starts upon reception of the first RTP or RTCP packet startRtcpPktRcvd - timer starts upon reception of the first RTCP packet Enumeration: 'disabled': 1, 'startRtcpPktRcvd': 4, 'startRtpOrRtcpPktRcvd': 3, 'startImmediately': 2.

This object is used to disable VQM or enable either RFC 3611 RTCPXR or Extended Network Quality Metrics VQM. disable - VQM is disabled. rfc3611Vqm - RFC 3611 RTCPXR. RTCPXR packet uses extended report block type as defined in RFC3611. xnq - Extended Network Quality Metrics. The difference between RFC 3611 RTCPXR and Extended Network Quality Metrics is the extended report block type used in RTCPXR packets. RFC 3611 RTCPXR uses voip-metrics block type as defined in RFC3611. Extended Network Quality Metrics uses a proprietary block type. If this object is set to 'disabled', the RTP terminations (object cmedxTermTypePkgIds in CISCO-MEGACO-EXT-MIB) on the card cannot be provisioned with the related packages, rtcpxr or pkgXnq, respectively. If this object is set to 'rfc3611Vqm', the RTP terminations (object cmedxTermTypePkgIds in CISCO-MEGACO-EXT-MIB) on the card can include package ID 'rtcpxr (27)' and/or 'xrbm (28)', but can not include package ID 'pkgXnq (32)'. If this object is set to 'xnq', the RTP terminations (object cmedxTermTypePkgIds in CISCO-MEGACO-EXT-MIB) on the card can include package ID 'pkgXnq (32)', but can not include 'rtcpxr (27)' or 'xrbm (28)'. Enumeration: 'xnq': 3, 'disable': 1, 'rfc3611Vqm': 2.

This object controls if RTCPXR (Real Time Control Protocol Extended Report) is enabled. If this object is set to 'true', both transmission and reception of RTCPXR packets are enabled; otherwise, transmission of RTCPXR packets is disabled while any received RTCPXR packets are ignored. If object cdspVqmControl is set to 'xnq (3)', this object is read-only with the value of 'true'.

This object is used to configure the RTCPXR report frequency. i.e. how many RTCP packets during the interval of every RTCPXR packet. The RTCPXR report is sent every 'cdspRtcpXrTransMultiplier' of RTCP packet. Example: If RTCP packet is sent every 10 ms(frequency of RTCP packet = 10 ms), and 'cdspRtcpXrTransMultiplier' is set to 3, then RTCPXR is sent every 3x10 ms = 30 ms(frequency of RTCPXR packet = 30 ms). This object is applicable only if 'cdspRtcpXrControl' is set to 'true'. If object cdspVqmControl is set to 'xnq (3)', this object is read-only with the value of '1'.

This object is the default minimum gap value configured for the IP stream. This object is applicable only if 'cdspVqmControl' is set to 'rfc3611Vqm'.

This object is the external R factor metric value. The value 127 means it is not applicable. This object is applicable only if 'cdspVqmControl' is set to 'rfc3611Vqm'. When 'cdspVqmControl' is not 'rfc3611Vqm', this object is set to 127.

This object specifies the packet loss concealment: (1) none: No packet loss concealment applied (2) simple: Cisco Proprietary packet loss concealment (3) g711A1: ITU G.711 Appendix I compliant Enumeration: 'simple': 2, 'g711A1': 3, 'none': 1.

This attribute specifies the threshold for Severely Errored Second on VQM. If the total number of milliseconds sampled as bad voice quality in one second period exceeds threshold, then this second is considered a 'severely errored second'. This object is applicable only if 'cdspVqmControl' is set to 'xnq'.

This attribute is used to enable or disable the transparent mode when establishing a non-transcoding IP-IP connection. The attribute does not apply for the transcoding IP-IP connections. A non-transcoding connection is one where the codec and packetization period are the same between the two IP terminations. When this object is set to 'true', the non-transcoding IP-IP connection is established in such a way that the bearer stream is not interrupted by the gateway. When this object is set to 'false', the non-transcoding IP-IP connection is established in a way the gateway terminates the bearer stream at one leg, and regenerates the bearer stream at the other leg.

This object specifies the voice mode for IP IP connections. normal : A normal Mode is a transcoding mode for IP-IP connections where the bearer properties will be different on two ends of a call. fastRoute : A voice call will be esatblished in this mode when the codec is same on two ends of a call but packetization period is different. tranparent : A voice call will be established in transparent mode when the all the bearer properties for a voice call are same on the two ends of a call. Enumeration: 'fastRoute': 2, 'transparent': 3, 'normal': 1.

This table contains DSP utilization information for all the codec families available in codec template currently active on VXSM.

An entry (conceptual row) in cdspUtilTable indicates the DSP capacity usage.
