System Traffic
In regards to the traffic capacity of electronic PABX, two kinds of descriptions are usually employed. One is Busy Hour Call Attempts (BHCA), which relates to the ability of the Central
Processor Unit (CPU). Another is the traffic handling capacity per line that relates to the handling capacity of each station. This technical information herein offers the traffic data for both cases.
Traffic Load
Traffic load is expressed as the quantity of traffic during the busy hour, the busiest
CCS– one CCS is equal to 100 seconds of telephone time, or 1/36 Erlang.
Erlang– one Erlang is equal to one hour of telephone time or 36 CCS.
CCS units are convenient when traffic is measured in small increments. For telephone traffic, a typical business generates about 6 CCS per telephone during the busy hour (1/6 Erlang).
Busy Hour
The hour during the day when traffic is highest is called the busy hour. Since this is the period when users are most likely to encounter blockage, the traffic load during the busy hour is the load you need to plan for. Traffic tables show the amount of traffic that can be handled during the busy hour. Within the busy hour, peaks will occur when blockage will be higher than the design objectives. It's not economical, however, to design a network to handle absolute peaks. Most networks are designed to cause some traffic to be blocked or overflow to other services.
One way to establish the load during the busy hour is to schedule traffic studies for a week when you know the load is high. Or, you can use tables developed by traffic engineers to estimate the busy hour load.
BHCA (Busy Hour Call Attempts)
BHCA of the UNIVERGE NEAX 2000 IPS is shown below.

Traffic Capacity In Erlang (For TDM Circuits)
Calculation Procedure
TDSW
Total system traffic capacity
T (erl) = I (erl) + E (erl)
In the UNIVERGE NEAX 2000 IPS, external traffic capacity is obtained from the Central Office Trunk (COT) quantity by employing the “Erlang B Table”. There is no limitation for the internal traffic capacity. The time slot is assigned for individual station and the connection between stations can be made without limitation through TDSW (Time Division Switch). Consequently, when describing the traffic capacity in Erlang, it is meaningless unless specifying the ratio of the internal and external traffic. From the above idea, total system traffic capacity
T (erl) = Internal Traffic
When assuming the external and internal traffic is even.
T (erl) = E (erl) + 0.5
For example:
System configuration:
•384 Lines
•64 C. O. Trunks
•External traffic: Internal traffic: = 7:4
In this system, external traffic capacity is obtained from “Erlang B” table. That is, 64 C. O. Trunks at grade of service of 0.01 can carry 50.6 erl. Total traffic capacity of this system is obtained from above 50.6 erl and ratio of external traffic as shown below:
Traffic capacity per station line
= 72.3erl ÷ 384 lines = 0.19 erl/L
Chapter 3 System Highlights
Traffic Capacity per Line (For TDM Circuits)
Traffic capacity per line (erl/L) can be calculated in accordance with the calculation procedure in Section 3.4. The traffic capacity per line at various line/truck configurations as the calculation result is shown in the following table. Though the following table does not cover all UNIVERGE NEAX 2000 IPS line/trunk configurations, it covers the typical TDM line/trunk configurations likely to be required in the actual system. Grade of service is considered as 0.01. Use the Erlang B Table to find the required number of DTMF register ports for a specificUNIVERGE NEAX 2000 IPS.
Unit = erl per line
Number of Trunks
Use Erlang B table to determine the number of trunks at a particular grade of service after using the following formulas:
Incoming: incoming ccs traffic
Outgoing: outgoing ccs traffic
Note: Traffic loads are measured in hundred call seconds, or CCS. Since there are 3,600 seconds in an hour, a line that's tied up for one hour measures 36 CCS traffic.

System Compliance
HIPAA Summary
The security standards set forth within HIPAA require encryption; authentication and audit trail measures to safeguard patient medical information during electronic data interchange (EDI) transactions between healthcare providers and third party reimbursement entities. These measures impact how patient medical information is exchanged, as well as accessed within a facility’s data network. Claims transmissions using Internet, intranets, extranets or private data networks are subject to HIPPA security standards as previously outlined.
HIPAA Compliance
Patient medical data is not accessed, stored or otherwise exchanged over a healthcare facility’s private branch exchange (PBX). However, an NEC manufactured private branch exchange does provide the flexibility to create detailed call accounting records that can be utilized to audit or otherwise track utilization of a facility’s NEC telecommunications system and/or PBX. A NEC PBX can also be configured torestrict access to designated telephone extensions. Furthermore, an NEC PBX can also be configured to utilizepassword access to individual telephones, voice mailboxes, etc. for purposes ofend user authentication.
So, under the guise of the security standards within HIPAA, NEC Private Branch Exchange equipment is HIPAA compliant and does provide the necessary security measures for use within any business setting that is subject to administrative rules outlined with the Health Insurance Portability and Accountability Act.
Department of Defense Compliance
The NEC NEAX 2000 Internet Protocol Switch (IPS) with software release D1.8.20, hereinafter referred to as the system under test (SUT), meets all of its critical interoperability requirements and is certified for joint use within the Defense Switched Network (DSN) as a Private Branch Exchange (PBX) 2.
However, since PBX2s do not support the Military Unique Feature Requirements detailed in reference (c), connectivity to the DSN is not authorized until a waiver is granted by the CJCS. PBXs are Military Department (MILDEP) controlled elements of the Defense Switched Network (DSN). PBX2 switches have no military unique features (MUFs) and can only serve Department of Defense (DOD),
