Overview
To configure the HPC/GETS feature, perform the following configuration steps:
The use of the GETS SOFTWARE is restricted in the U.S. and U.S. TERRITORIES to NS/EP users authorized by the Office of the Manager, National Communications System (OMNCS).
SBC Configuration
This section describes the minimal configuration of the SBC for the HPC/GETS features.
The steps mentioned below are not strictly sequential. However, Ribbon recommends executing them in the order mentioned in this document.
Configure hpcCallLimits and policer rate in sipCacProfile
Command Syntax
% set profiles sipCacProfile <profile_name> hpcCallLimits maxCalls <unlimited | blockAll | 1-1000> maxIngressRate <unlimited | 1-2000> ingressRateInterval <1-30> bucketSize <1-4000>
For more information on configuring hpcCallLimits
, refer to the section "HPC Call Limits" of the page SIP CAC Profile - CLI.
Relevant GETS Parameters
Command Example
% set profiles sipCacProfile testSipCacProfile hpcCallLimits maxCalls 500 maxIngressRate 50 ingressRateInterval 10 bucketSize 32 % commit
Configure DSCP marking for DIAMETER+ packets
Command Syntax
Configure the
dscpProfile.
% set profiles services dscpProfile <dscp_profile_name> hpcDscpValue <0-63> dscpValue <0-63> state <disabled | enabled>
Attach the configured
dscpProfile
withpolicyServer globalConfig.
% set system policyServer globalConfig dscpProfile <dscp_profile_name>
Configure
mediaPortRange.
% set system media mediaPortRange highPriorityPortRangeLocation <bottom | top> highPriorityPortRangeSize <0-25>
For more information on configuring dscpProfile
, refer to DSCP Profile - CLI.
Relevant GETS parameters
Command Example
% set profiles services dscpProfile HPC hpcDscpValue 32 dscpValue 22 state enabled % commit % set system policyServer globalConfig dscpProfile HPC % commit % set system media mediaPortRange highPriorityPortRangeLocation bottom highPriorityPortRangeSize 10 % commit
The percentage specified as highPriorityPortRangeSize
is used as the High Priority reserve for both Media Port Range (MPR) and LIF bandwidth. For more information on Media Port Range, refer to Media System - CLI.
The configuration for the parameters highPriorityPortRangeLocation
and highPriorityPortRangeSize
defines the High Priority Media Port Range (HPMPR) as a subset of the overall MPR. The SBC uses the configuration to quickly identify UDP packets (both media and non-media) arriving within the overall MPR, and prioritizes them while processing ingress UDP packets. For GETS/HPC applications, Ribbon recommends reserving 10% of the MPR as HPMPR. If additional SIP Signaling Ports (besides the default port 5060), and/or other Control UDP ports are within the overall MPR, Ribbon recommends configuring them within the HPMPR. Such configuration ensures that during congestion, they are prioritized while processing ingress packets.
For example, if the overall MPR is defined as 1024-65535, and the High Priority Port Range is 10% (starting with the lower limit of MPR), then the HPMPR is 1024-7475. Ribbon recommends configuring additional SIP Signaling and other Control UDP ports within the range 1024-7475. In case of congestion, such configuration ensures that while processing ingress packets, packets received at ports within the range configured for HPMPR are prioritized. Normal calls are allocated local UDP ports ranging from 7476-65535, and GETS/HPC calls are allocated local UDP ports ranging from 1024-7475.
Configure DSCP for useRecvdValue
Command Syntax
% set profiles services hpcCallProfile <profile_name> dscp <egress | ingress> useRecvdValue <disabled | enabled>
The SBC supports configuring up to 256 HPC Call Profiles.
For more information on configuring hpcCallProfile
, refer to HPC Call Profile - CLI.
Relevant GETS parameters
Command Example
The following examples are applicable for egress and ingress call legs:
% set profiles services hpcCallProfile testHpcCallProfile dscp egress useRecvdValue disabled % commit % set profiles services hpcCallProfile testHpcCallProfile dscp ingress useRecvdValue disabled % commit % set profiles services hpcCallProfile testHpcCallProfile dscp egress useRecvdValue enabled % commit % set profiles services hpcCallProfile testHpcCallProfile dscp ingress useRecvdValue enabled % commit
Configure HPC Call Queuing
Prerequisite
The prerequisite step is OPTIONAL; implement it based on the configuration requirement.
By default, the SBC sends a response code 600 when the call queue is full. If the configuration requirement is to send the response code 503 when the call queue is full, execute the following commands:
Configure
causeMap 161
to correspnd withsipCause 503
.
Command Syntax:% set profiles signaling sipCauseCodeMapping cpcToSipCauseMapProfile <profile_name> baseProfile defaultCpcSip causeMap 161 sipCause 503
Command Example:% set profiles signaling sipCauseCodeMapping cpcToSipCauseMapProfile TEST baseProfile defaultCpcSip causeMap 161 sipCause 503
Associate the
cpcSipCauseMappingProfile
used in the previous step withsignaling causeCodeMapping
.
Command Syntax:% set addressContext default zone <zone_name> sipTrunkGroup <ingress_trunk_group> signaling causeCodeMapping cpcSipCauseMappingProfile <profile_name>
Command Example:% set addressContext default zone ZONE1 sipTrunkGroup INGRESS_TG signaling causeCodeMapping cpcSipCauseMappingProfile TEST
Command Syntax
Configure the
queueLength
forcallQueuing
at aglobal
level.% set global callQueuing queueLength <1-4096>
Configure the Call Admission Control (
cac
) forcallLimit
andhpcOverSubscription
restrictions.% set addressContext default zone <INTERNAL_ZONE> sipTrunkGroup <Ingress_TG | Egress_TG> cac callLimit <0-2147483647> hpcOversubscription <0-100>
Configure the
queue
for thehpcCallProfile
.% set profile services hpcCallProfile <hpc_call_profile> queue length <1-256> timeout <1-90> state <disabled | enabled>
Attach the configured
hpcCallProfile
with ingress or egress trunk group.% set addressContext default zone <INTERNAL_ZONE> sipTrunkGroup <Ingress_TG | Egress_TG> services hpcCallProfile <hpc_call_profile>

featureCode fc
numberTranslation nt
You can configure the SBC for matching any of supported GETS string values with the received string. The following table describes the maximum number of configurations allowed for the supported GETS string types.
