Overview

Use the Packet Service Profile screen to create or edit a Packet Service Profile. Each Packet Service Profile is configured for a pair of gateways and includes entries for up to four audio/video encoding methods. The pair of gateways can be originating and destination gateways in the same gateway group, or can be originating and destination gateways in an inter-gateway group.

Parameter

Description

Fields common to the Create New and Copy Windows

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

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.

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 (default) — the local audio encoding priority order take precedence. Disabled

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
 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
 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
  •  – RTCP is used for the call.
Termination For Passthrough
Specifies 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
  • the Rtcp

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:

Table 2: honorAnswerPreference



honorAnswerPreference vs. honorOfferPreference 

HOP Flag StateHAP Flag StateSBC Behavior
EnableDisable

The 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.

EnableEnable

The 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.

DisableEnable

The 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).

Data Rate Management Type

The following data rate management types are supported:

  • 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.
  • Type2 Transfer Of Tcf

  •  – (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).

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).
