1System Provision - Packet Service Profile Parameters

 

Parameter

Description

Name

The packet service profile entry ID used to identify a particular packet service profile entry.

Silence Factor

The silence factor is the percentage of call time for which silence is expected. It is used to reduce expected call bandwidth.

The default value is 40.

Type of Service

Specifies the type of service (TOS) parameter to be provided in the IP header for voice packets. It is the decimal number that is included as is in the 8-bit TOS field of the IP header. Note that this number should be four times the DSCP value that you want to set in the high order 6 bits of the 8-bit TOS field.

The default value is 0.

Voice Initial Playout Buffer Delay

Specifies a numeric value, in milliseconds (ms), for the voice initial playout buffer delay required to absorb the maximum expected packet jitter across the network, in the range of 1 ms to 50 ms in increments of 1 ms.

The default value is 10 ms.

Peer Absence Action

Specifies the action to be taken when loss of bearer plane connectivity is detected on the channel. Possible actions are:
• None—No action taken.
• Trap—Generate an SNMP trap.
• Trap and Disconnect—Generate an SNMP trap and disconnect the call.
Requires the RTCP check box to be selected, which enables RTCP on the channel. The default setting is None.

AaL1 Payload Size

Specifies the ATM Adaption Layer Type 1 (AAL-1) payload size. For G.711, the possible values are 40, 44, or 47 bytes.
The default value is 47 bytes.

Preferred RTP Payload Type for DTMF Relay

Specifies the preferred RTP payload type in the RTP header of audio packets for this encoding. (default = 128). This parameter is only used for 8 kHz clock rate. DTMF payload type of each subsequent clock rate (16 kHz, 24 kHz, etc.) is incremented by 1.

Note

Using the default value of "128" for Preferred Rtp Payload Type For Dtmf Relay implies that the preferred DTMF value (from the system configurable) is used for this profile.

Note

Refer to Interwork Dtmf Without Transcoding parameter on Packet Service Profile - Flags page for valid values to use with this parameter when Interwork Dtmf Without Transcoding parameter is enabled.

If Interwork Dtmf Without Transcoding is enabled, ensure Preferred Rtp Payload Type For Dtmf Relay is set to a valid value (96-127). If Preferred Rtp Payload Type For Dtmf Relay value is invalid (set to "128"), the system may fail to pick up the value configured using "set system dspPad rtpDtmfRelay" option because DSPs are not used for the call.

Media Packet COS

Applies a Class of Service (COS) marking to be set in the User Priority field of the Ethernet VLAN tag header on media packets transmitted on a call leg that uses this packet service profile. Has an effect only if the network interface supports 802.1Q tagged Ethernet frames. The default value zero corresponds to best effort. The value range is 0-7.

Honor Remote Precedence

Specifies whether the audio encoding priority order of the local packet service profile takes precedence over the remote peer's audio encoding priority order when creating the priority order of the audio encodings that are common to both.

Possible choices are:
• disabled—When selected, Disabled makes the local audio encoding priority order take precedence. Disabled also makes the local Secure RTP/RTCP settings and crypto suite priority order take precedence.
• enabled—When selected, Enabled makes the remote peer's audio encoding priority order take precedence. For ingress call legs, Enabled also makes the remote peer's Secure RTP/RTCP settings and crypto suite priority order take precedence. The default setting is Disabled.

Send Route PSPPrecedence

Fields that appear only on the Copy Window
Data Calls 
Preferred Rtp Data Payload Type

The RTP Payload Type included in the RTP header of the data packet. The value ranges from 0 to 127 and the default value is 56.

Initial Playout Buffer DelayUsed for G.711 only. This is the initial playout delay for calls with a data bearer channel, for example, ISDN 64K data calls. This value is configured separately from the initial playout delay for voice channels (Voice Initial Playout Buffer Delay) so providers can trade off delay on data calls versus the likelihood of jitter causing delay changes while the playout buffer adapts. Some data bearer calls are very sensitive to delay changes (such as H.320 video conferencing), so a higher initial delay should reduce the chance of jitter bursts causing problems. (range: 5-50 / default = 50).
Packet Size

Specifies the maximum data packet size (Kilobits). The options are:

  • 10
  • 20
  • 30
  • 40
RTCP Options 
Rtcp

Specifies whether to enable RTCP. The options are:

  • Disable (default)
  • Enable – RTCP is used for the call.
Termination For PassthroughSpecifies RTCP termination behavior for pass-through calls. The options are:
  • Disable (default) — RTCP is relayed between the endpoints for pass-through calls.
     
  • Enable — Enable this option (as well as the Rtcp option) on one leg to terminate RTCP sessions on each leg for pass-through calls. If RTCP and RTCP termination is enabled on one leg of a pass-through call, RTCP is terminated and originated for that leg. If RTCP is enabled on both legs on the pass-through call, irrespective of Termination For Passthrough settings, RTCP is always relayed.

Info

titleNOTE:

This parameter is visible only when Rtcp is enabled.

Enable RTCPFor Held Calls

If this option is enabled, the SBC ignores the configured RR/RS values in the Packet Service Profile and send RR/RS = 0 in the offer/answer and disables RTCP when the call is active. When the call is HELD, and a RE-INVITE is sent, the SBC uses the configured values in the Packet Service Profile for RTCP bandwidth and enables RTCP. When the call is RESUMED, the SBC again disables RTCP by sending RR/RS=0 in the RE-INVITE.

The value of RR ranges from 100-4000 and the value of RS ranges from 100-3000.

If this flag is disabled, the older behavior of SBC is applicable.

The options are:

  • Disabled (default)
  • Enabled

    enableEnabledisableDisableThe SBC selects a codec order of precedence in the offered SDP, irrespective of whether it is a pass-through or transcoded codec (if transcoding is defined for that codec). The SBC as part of media lock-down may send a re-INVITE to egress peer. Note that the preference on the answerer side is given to a pass-through codec.
    enableEnableenableEnableThe SBC gives preference to HAP over HOP in case of conflict. The Honor Remote Preference (HRP) flag on the answerer leg decides the preference order. Based on that preference list, the SBC selects a codec with highest preference from answer SDP that can be used even if it requires transcoding. Note that this may cause the selection of a codec on the other side leg not to be honored. This happens in case of a pass-through call.
    disableDisableenableEnableThe SBC gives preference to answerer codec order that is created based on HRP flag. The most preferred codec is chosen as received in the answer SDP, irrespective of whether it is a pass-through or a transcoded codec (if transcoding is defined for that codec).

      Spacevars
      0product
      forwards the events in the egress leg to this peer using the named event RTP payload. When 
      Spacevars
      0product
      is configured for a pass-through call and it receives DTMF events other than 0-15 from the ingress peer, it does not offer any DTMF events to the egress endpoint.
    Interwork Dtmf Without Transcoding

    Enable flag to interwork DTMF with out-of-band RFC2833 without using transcoding. The options are:

    • disable (default)
    • enable
    Note

    If you enable Interwork Dtmf Without Transcoding, ensure Preferred Rtp Payload Type For Dtmf Relay is set to a valid value (96-127). If Preferred Rtp Payload Type For Dtmf Relay value is invalid (set to "128"), the system may fail to pick up the value configured using "set system dspPad rtpDtmfRelay" command because DSPs are not used for the call.

    Dscp Passthrough

    When enabled on both the Ingress and Egress call leg, the DSCP value in the IP header of the media packets is transparently passed through the system. Once media is received from the peer, any value set in the Type Of Service field on the Packet Service Profile has no effect when Dscp Passthrough is configured on both legs for the associated call. The options are:

    • disable (default)
    • enable
    Ssrc Randomize

    Enable flag to generate a new SSRC (using a random value) along with a new timestamp on a new RTP stream whenever a resource is reactivated (due to change in codec, etc.). SSRC randomization reduces the probability of collision in large groups and simplifies the process of group sampling that depends on uniform distribution of SSRCs. The options are:

    • disable (default)
    • enable
    T38 Data Rate Management Type

    The following Data Rate Management Types are supported:

    • type1LocalGenerationOfTcf – Type 1 data rate management requires that the Training Check Frame (TCF) training signal is generated locally by the receiving gateway. Data rate management is performed by the emitting gateway based on training results from both PSTN connections. Type 1 is used for TCP implementations and is optionally used with UDP implementations.
    • type2TransferOfTcf – (default) Type 2 data rate management requires that the TCF is transferred from the sending gateway to the receiving gateway rather than having the receiving gateway generate it locally. Speed selection is done by the gateways in the same way as they would on a regular PSTN connection. Data rate management type 2 requires the use of UDP and is not recommended for use with TCP.
    Low Speed Number Of Redundant Packets This field specifies the number of redundant IFP messages sent in a UDP packet for T.38 low speed fax transmission, and applies only if the T.38 error correction type is redundancy. (range: 0-2 / default = 1).Max Bit Rate

    Use this object to select the T.38 Maximum Bit Rate which controls and manipulates bits 11, 12, 13, and 14 in the DIS command received by the SBC from either the TDM circuit interface or the T.38 packet interface:

    • 2.4Kbits_s – For modem type ITU-T V.27ter fall-back mode.
    • 4.8Kbits_s – For modem type ITU-T V.27ter.
    • 9.6Kbits_s – For modem types ITU-T V.27ter and V.29.
    • 14.4Kbits_s – (default) For modem types ITU-T V.27ter, V.29, and V.17. This setting is used to constrain the type of modem modulation schemes.
     Number Of Redundant PacketsUse this parameter for high-speed fax relay to specify the number of redundant Internet Facsimile Protocol (IFP) messages sent in a User Datagram Packet (UDP) for fax transmission. (range: 0-2 / default = 1).  Ecm Ecm Preferred

    Use this flag to allocate DSP resources, when available, for T.38 Error Correction Mode (ECM) calls.

    Update Crypto Keys On Modify

    For an SRTP call, if this flag is enabled in Packet Service Profile and call leg mode is changed from sendonly/inactive/recvonly to sendrecv, the SBC generates a new set of crypto attributes. The options are:

    • disable (default)
    • enable
    Video Calls Max Video Bandwidth

    The maximum allowable session bandwidth (in Kbps) for a call that includes video streams. This value includes the bandwidth for all streams in the call (audio, video, BFCP, and so on). If "0" is set as the value, video calls are not allowed; and only audio calls can be set up following the normal allocation process (range: 0-50000 Kbps / default = 10).

    Video Bandwidth Reduction Factor

    The amount, as a percentage, to reduce the session bandwidth allocation for calls that include video streams. This setting only affects the internal allocation of bandwidth used for the calls (does not affect the signaling). For example, if the reduction factor is "20", the bandwidth allocated for calls is reduced by 20%. In other words, if the normal bandwidth allocation for calls is 1000 Kbps, a 20% reduction equates to a new 800 Kbps bandwidth. (range: 0-100 / default = 0).

    Ipv4TosIPv4 type of service. (range: 0-255 / default = 0).Ipv6Traffic Class

    IPv6 traffic class. (range: 0-255 / default = 0).

    1System Provision - Packet Service Profile Parameters

     

    Parameter

    Description

    Name

    The packet service profile entry ID used to identify a particular packet service profile entry.

    Silence Factor

    The silence factor is the percentage of call time for which silence is expected. It is used to reduce expected call bandwidth.

    The default value is 40.

    Type of Service

    Specifies the type of service (TOS) parameter to be provided in the IP header for voice packets. It is the decimal number that is included as is in the 8-bit TOS field of the IP header. Note that this number should be four times the DSCP value that you want to set in the high order 6 bits of the 8-bit TOS field.

    The default value is 0.

    Voice Initial Playout Buffer Delay

    Specifies a numeric value, in milliseconds (ms), for the voice initial playout buffer delay required to absorb the maximum expected packet jitter across the network, in the range of 1 ms to 50 ms in increments of 1 ms.

    The default value is 10 ms.

    Peer Absence Action

    Specifies the action to be taken when loss of bearer plane connectivity is detected on the channel. Possible actions are:
    • None—No action taken.
    • Trap—Generate an SNMP trap.
    • Trap and Disconnect—Generate an SNMP trap and disconnect the call.
    Requires the RTCP check box to be selected, which enables RTCP on the channel. The default setting is None.

    AaL1 Payload Size

    Specifies the ATM Adaption Layer Type 1 (AAL-1) payload size. For G.711, the possible values are 40, 44, or 47 bytes.
    The default value is 47 bytes.

    Preferred RTP Payload Type for DTMF Relay

    Specifies the preferred RTP payload type in the RTP header of audio packets for this encoding. (default = 128). This parameter is only used for 8 kHz clock rate. DTMF payload type of each subsequent clock rate (16 kHz, 24 kHz, etc.) is incremented by 1.

    Note

    Using the default value of "128" for Preferred Rtp Payload Type For Dtmf Relay implies that the preferred DTMF value (from the system configurable) is used for this profile.

    Note

    Refer to Interwork Dtmf Without Transcoding parameter on Packet Service Profile - Flags page for valid values to use with this parameter when Interwork Dtmf Without Transcoding parameter is enabled.

    If Interwork Dtmf Without Transcoding is enabled, ensure Preferred Rtp Payload Type For Dtmf Relay is set to a valid value (96-127). If Preferred Rtp Payload Type For Dtmf Relay value is invalid (set to "128"), the system may fail to pick up the value configured using "set system dspPad rtpDtmfRelay" option because DSPs are not used for the call.

    Media Packet COS

    Applies a Class of Service (COS) marking to be set in the User Priority field of the Ethernet VLAN tag header on media packets transmitted on a call leg that uses this packet service profile. Has an effect only if the network interface supports 802.1Q tagged Ethernet frames. The default value zero corresponds to best effort. The value range is 0-7.

    Honor Remote Precedence

    Specifies whether the audio encoding priority order of the local packet service profile takes precedence over the remote peer's audio encoding priority order when creating the priority order of the audio encodings that are common to both.

    Possible choices are:
    • disabled—When selected, Disabled makes the local audio encoding priority order take precedence. Disabled also makes the local Secure RTP/RTCP settings and crypto suite priority order take precedence.
    • enabled—When selected, Enabled makes the remote peer's audio encoding priority order take precedence. For ingress call legs, Enabled also makes the remote peer's Secure RTP/RTCP settings and crypto suite priority order take precedence. The default setting is Disabled.

    Send Route PSPPrecedence

    Specifies the audio encoding order preference in outgoing messages only.
    • disabled—When selected, Disable the audio encoding order preference.
    • enabled—When selected, Enable the audio encoding order preference.

If Preferred Rtp Payload Type For Dtmf Relay value is invalid (set to "128"), the system may fail to pick up the value configured using "set system dspPad rtpDtmfRelay" option because DSPs are not used for the call.

    Media Packet COS

    Applies a Class of Service (COS) marking to be set in the User Priority field of the Ethernet VLAN tag header on media packets transmitted on a call leg that uses this packet service profile. Has an effect only if the network interface supports 802.1Q tagged Ethernet frames. The default value zero corresponds to best effort. The value range is 0-7.

    Honor Remote Precedence

    Specifies whether the audio encoding priority order of the local packet service profile takes precedence over the remote peer's audio encoding priority order when creating the priority order of the audio encodings that are common to both.

    Possible choices are:

    • disabled—When selected, Disabled makes the local audio encoding priority order take precedence. Disabled also makes the local Secure RTP/RTCP settings and crypto suite priority order take precedence.
    • enabled—When selected, Enabled makes the remote peer's audio encoding priority order take precedence. For ingress call legs, Enabled also makes the remote peer's Secure RTP/RTCP settings and crypto suite priority order take precedence. The default setting is Disabled.

    Send Route PSPPrecedence

    Specifies the audio encoding order preference in outgoing messages only. The options are:

    • disabled—When selected, Disable the audio encoding order preference.
    • enabled—When selected, Enable the audio encoding order preference.
    Data Calls 
    Preferred Rtp Data Payload Type

    The RTP Payload Type included in the RTP header of the data packet. The value ranges from 0 to 127 and the default value is 56.

    Initial Playout Buffer DelayUsed for G.711 only. This is the initial playout delay for calls with a data bearer channel, for example, ISDN 64K data calls. This value is configured separately from the initial playout delay for voice channels (Voice Initial Playout Buffer Delay) so providers can trade off delay on data calls versus the likelihood of jitter causing delay changes while the playout buffer adapts. Some data bearer calls are very sensitive to delay changes (such as H.320 video conferencing), so a higher initial delay should reduce the chance of jitter bursts causing problems. (range: 5-50 / default = 50).
    Packet Size

    Specifies the maximum data packet size (Kilobits). The options are:

    • 10
    • 20
    • 30
    • 40
    Rtcp Options 
    Rtcp

    Specifies if the Rtcp option should be enabled or not. The options are:

    • disable (default)
    • enable – RTCP is used for the call.
    Termination For Passthrough
    Note

    This parameter is visible only when Rtcp is enabled.

    Enable RTCPFor Held Calls

    If this flag is enabled, SBC ignores the configured RR/RS values in the Packet Service Profile and send RR/RS = 0 in the offer/answer and disables RTCP when the call is active. When the call is HELD, and a RE-INVITE is sent, SBC uses the configured values in the Packet Service Profile for RTCP bandwidth and enables RTCP. When the call is RESUMED, SBC again disables RTCP by sending RR/RS=0 in the RE-INVITE.

    The value of RR ranges from 100-4000 and the value of RS ranges from 100-3000.

    If this flag is disabled, the older behavior of SBC is applicable.

    options are:

    • disabled (default)
    • enabled
    Note

    This parameter is visible only when Rtcp is enabled.

    Packet Loss Threshold

    Enter a value between 0-32767 to specify the Packet Loss Threshold (number of lost packets/100,000) which will trigger a Packet Loss Action. This parameter is required if RTCP is enabled. When set to “0”, no packet loss inactivity detection is performed. The value ranges from 0 to 32767 and the default value is 0. The value ranges from 0 to 32767 and the default value is 0.

    Note

    Configuring this parameter to a value less than 400 disables threshold detection, so be sure to use a value in the range of 400 to 32767 to enable threshold detection.

    This setting can be used in conjunction with   Media Peer Inactivity. To set media peer inactivity timeout value, see Media Peer Inactivity parameter in Media Peer Inactivity page.

    For an example configuration of this parameter, see Packet Service Profile (CLI) page.

    Note

    This parameter is visible only when Rtcp is enabled.

    Rr Bandwidth

    Specifies the RTCP bandwidth allocated to active data senders. The value ranges from 100 to 4000 and the default value is 250.

    Note

    This parameter is visible only when Rtcp is enabled.

    Rs Bandwidth

    Specifies the RTCP bandwidth allocated for receivers. The value ranges from 100 to 3000 and the default value is 250.

    Note

    This parameter is visible only when Rtcp is enabled.

    Packet Loss ActionSpecifies what Packet loss action to take when packet threshold is exceeded. The options are:
    • none — Take no action.
    • packetLossTrap — Generate trap.

    • packetLossTrapAndDisconnect — Generate trap and disconnect.

    Note

    This parameter is visible only when Rtcp is enabled.

     Silence Insertion Descriptor G711Sid Rtp Payload TypeSpecifies the G.711 Silence Insertion Descriptor (SID) RTP payloadType. (range: 0-127 / default = 19). Heartbeat

    HOP Flag StateHAP Flag StateSBC Behavior
    enabledisableThe SBC selects a codec order of precedence in the offered SDP, irrespective of whether it is a pass-through or transcoded codec (if transcoding is defined for that codec). The SBC as part of media lock-down may send a re-INVITE to egress peer. Note that the preference on the answerer side is given to a pass-through codec.
    enableenableThe SBC gives preference to HAP over HOP in case of conflict. The Honor Remote Preference (HRP) flag on the answerer leg decides the preference order. Based on that preference list, the SBC selects a codec with highest preference from answer SDP that can be used even if it requires transcoding. Note that this may cause the selection of a codec on the other side leg not to be honored. This happens in case of a pass-through call.
    disableenableThe SBC gives preference to answerer codec order that is created based on HRP flag. The most preferred codec is chosen as received in the answer SDP, irrespective of whether it is a pass-through or a transcoded codec (if transcoding is defined for that codec).

    Note

    If you enable Interwork Dtmf Without Transcoding, ensure Preferred Rtp Payload Type For Dtmf Relay is set to a valid value (96-127). If Preferred Rtp Payload Type For Dtmf Relay value is invalid (set to "128"), the system may fail to pick up the value configured using "set system dspPad rtpDtmfRelay" command because DSPs are not used for the call.

    Dscp Passthrough

    When enabled on both the Ingress and Egress call leg, the DSCP value in the IP header of the media packets is transparently passed through the system. Once media is received from the peer, any value set in the Type Of Service field on the Packet Service Profile has no effect when Dscp Passthrough is configured on both legs for the associated call. The options are:

    • disable (default)
    • enable
    Ssrc Randomize

    Enable flag to generate a new SSRC (using a random value) along with a new timestamp on a new RTP stream whenever a resource is reactivated (due to change in codec, etc.). SSRC randomization reduces the probability of collision in large groups and simplifies the process of group sampling that depends on uniform distribution of SSRCs. The options are:

    • disable (default)
    • enable
    T38 Data Rate Management Type

    The following Data Rate Management Types data rate management types are supported:

    • type1LocalGenerationOfTcf Type1 Local Generation Of Tcf – Type 1 data rate management requires that the Training Check Frame (TCF) training signal is generated locally by the receiving gateway. Data rate management is performed by the emitting gateway based on training results from both PSTN connections. Type 1 is used for TCP implementations and is optionally used with UDP implementations.
    • type2TransferOfTcf Type2 Transfer Of Tcf – (default) Type 2 data rate management management requires that the TCF is transferred from the sending gateway to the receiving gateway rather than having the receiving gateway generate it locally. Speed selection is done by the gateways in the same way as they would on a regular PSTN connection. Data rate management type 2 requires the use of UDP and is not recommended for use with TCP.
    Low Speed Number Of Redundant Packets This field specifies the number of redundant IFP messages sent in a UDP packet for T.38 low speed fax transmission, and applies only if the T.38 error correction type is redundancy. (range: 0-2 / default = 1).Max Bit Rate

    Use this object to select the T.38 Maximum Bit Rate maximum bit rate which controls and manipulates bits 11, 12, 13, and 14 in the DIS command received by the SBC from either the TDM circuit interface or the T.38 packet interface:

    Video Calls Max Video Bandwidth

    The maximum allowable session bandwidth (in Kbps) for a call that includes video streams. This value includes the bandwidth for all streams in the call (audio, video, BFCP, and so on). If "0" is set as the value, video calls are not allowed; and only audio calls can be set up following the normal allocation process (range: 0-50000 Kbps / default = 10).

    Video Bandwidth Reduction Factor

    The amount, as a percentage, to reduce the session bandwidth allocation for calls that include video streams. This setting only affects the internal allocation of bandwidth used for the calls (does not affect the signaling). For example, if the reduction factor is "20", the bandwidth allocated for calls is reduced by 20%. In other words, if the normal bandwidth allocation for calls is 1000 Kbps, a 20% reduction equates to a new 800 Kbps bandwidth. (range: 0-100 / default = 0).
