View Route Group P.01 Grade of Service Summary Report

This report lets you do call routing capacity planning by generating the usage summary of Cisco Route Groups configured on Cisco Call Manager clusters. This report is applicable only for the Route Groups that reference channelized Cisco Voice Gateways or channelized Cisco Voice Gateway interfaces such as T1/E1 PRIs. This report captures a summary of the usage for any Route Group as a logical bundle of channels along with the summary of usage for each gateway device referenced by the Route Group.

The report displays the final result for the group and each gateway in the group and also includes an indicator of the Grade of Service for the set as well as for each Gateway device in the set. This indicator indicates a percent of P.01 Grade Of Service for the number of channels in the set of Gateways for the group. the report displays the compliance indicator for each Gateway device in the selected group.

P.01 Grade of Service indicates, for a given number of channels in a logical bundle, the Busy Hour Traffic (BHT) that the set representing the logical bundle can sustain with a 0.01% blockage.

The report uses hourly aggregated Cisco CDR reported call information stored in NPS under Cisco IP Telephony Gateway Calls reporting package to arrive at the conclusions.

For each gateway device in the set, the report first determines the Total calls, the Average Duration for a call and the Busiest Day Calls carried by the gateway in the selected time period. The report then estimates the Busiest Hour Calls offered to the gateway by calculating a fraction of Busiest Day Calls. The report uses a fractional multiplier of 14% by default. You can configure this multiplier before generating the report. After estimating the Busiest Hour Calls offered, the report estimates the Busiest Hour Traffic (BHT) by calculating the Busiest Hour Calls offered multiplied by the Average Duration for a Call. The report then compares the BHT against the P.01 GoS BHT for the number of channels in the gateway device and displays the comparison as a percentage and indicates the compliance to P.01 GoS Standards.

The report performs similar calculations for the Route Group as a set of gateways and therefore treats the set of gateways as a logical bundle of channels. The report first determines the Total Calls, the Average Duration for a call, and the Busiest Day Calls carried for the complete set of gateways referenced by the Route Group. The Average Duration for a call and the Busiest Day Calls carried are for the set of gateways and is not the sum of the same parameters for all the gateways. The report then estimates the Busiest Hour Calls offered for the Route Group by calculating a fraction of Busiest Day Calls carried for the same. The report uses a fractional multiplier of 14% by default. You can configure this multiplier before generating the report. After estimating the Busiest Hour Calls offered, the report estimates the Busiest Hour Traffic (BHT) by calculating the Busiest Hour Calls offered multiplied by the Average Duration for a Call. The report then compares the BHT against the P.01 GoS BHT for the number of channels in the gateway device and displays the comparison as a percentage and indicates the compliance to P.01 GoS Standards. The total number of channels for a Route Group is the sum of the number channels for all the gateways referenced by the Route Group.

To access the Route Group P.01 GoS Summary Report:

1. Log on to the NNMi console as an operator.
2. Click Cisco IP Telephony > UCM Clusters.
3. Select a Cisco Unified Communications Manager cluster of your choice, and then click Actions > IP Telephony > Route Group P.01 GoS Summary. The Grade of Service for Route Group window opens.
4. Specify the following details on the left panel:
   • Fraction*: Specify the numeric value that denotes the percentage of busiest day calls to be taken as the estimated busy hour calls offered. The default value is 14 for this parameter.
   • Start Date: Specify the start date for the report.
   • End Date: Specify the end date for the report.
   recommends that you provide a gap of a day or more between the start date and the end date to generate reports, By default, the NNM iSPI for IP Telephony generates the report for the past one week.
   • Direction: Select one of the following options to specify the type pf calls that must be considered when generating reports.
     • In: indicates incoming calls.
     • Out: indicates outgoing calls.
     • Both: indicates both incoming and outgoing calls.
   • Time Zone: Select the time zone configured in your system. You must select the Default time zone if NNMi and the iSPI Performance for Metrics are installed on different time zones.
   • Cluster ID: Specifies the cluster identifier.
   • Route Groups: Select the route groups based on which you want to monitor the usage of the gateways and calculate the P.01 GoS score.
5. Click Submit. The report for the selected Cisco Unified Communications Manager cluster opens.

The Selection Order in the report indicates the priority or position of the gateway device within a Route Group.

The GOS Reference Chart lists the number of channels and the recommended GoS score for the respective number of channels.
