10 Traffic Considerations General 10.1 This part details traffic limitations. Information includes: l Busy Hour Call Attempt (BHCA) l System Traffic Capacity l Grade of Service l Receiver Provisioning l Trunk Distribution. Traffic Limitations 10.2 Traffic capacities are specified on a per line basis in terms of calls per hour, erlangs, and CCS. A basicsystem consists of 80 lines and 16 trunks. This configuration has been specified to meet the following heavy traffic characteristics: Busy Hour Call Attempts System (BHCA) Mean 99.9 % Peak Per Second 0.090 0.186 Per Hour 325 671 Bothway Traffic Capacity 426 Calls/Hour Erlang 14.5 ccs 522.0 Typical configured system quantities as per ATT 48002 are: Light -10% Medium - 50 % Heavy -90 % Lines Trunks Lines Trunks Lines Trunks 75 8 75 12 75 19 50 6 50 IO 50 15 25 5 25 7 25 IO March 1997 Issue 1 Revision 0 10-l
Engineering Information Grade of Service 10.3 The Grade of Service (GOS) in terms of blocking is outlined in Table 10-I. . . Table 10-l Grade Of Service (GOS) Link/Resource Blocking Link Blocking: Blocking Probability Peripheral to Network < 0.1% Network to Network 0.0% Resource Blocking Software < 0.01% DTMF Receivers, Trunks Receiver Provisioning provisioning dependent 10.4 The number of DTMF receivers required to be installed in the PABX depends on var- ious factors, such as the number of lines and trunks installed, the amount of traffic flow estimated for the system and the desired grade of service. Receivers are not re- quired for DNIC devices. To determine the quantity of DTMF receivers required, the following assumptions were made: l Average receiver holding time for intercom call is 6 seconds l Average receiver holding time for a trunk call is 17.4 seconds l Holding time for receivers is exponential l Call originations are Poisson distribution l Call holding times are exponential. The MCC II contains seven receivers. If additional receivers are required, receiver modules can be added to a Universal Card. Each receiver module contains four receivers. For a given load (heavy, medium and light traffic), the minimum number of required receivers was determined for the following grades of service (ABSBH - Average busy Season Busy Hour): 9 ABSBH = 99.0: 99.0 % of all receiver requests serviced within 3 seconds l ABSBH = 99.99: 99.99 % of all receiver requests serviced within 3 seconds The following calculations are used to generate Table 1 O-2, Table I O-3, and Table I O-4: Receiver Holding Time ( h ) = 6 x (% intercom traffic) + 17.4 x (% trunk traffic) Seconds Receiver Traffic (A) = (Originating Calls per hour) x (Receiver holding time (set)) Erlangs 3600 1 o-2 Issue 1 Revision 0 March 1997
Traffic Considerations Multiple of holding time (t) = * h (~1 Probability of delay greater than t (P(>t)) = I - ABSBH ii 00 Using Erlang C formula delay curves and knowing t, A, P(>t), the minimum number of receivers can be obtained. Because the MCC II contains seven DTMF receivers, an SX-200 ML PABX configured at 96 ports (72 ONS and 24 digital trunks) will not require additional trunks to support heavy traffic.
