As with most of our products, it is always best to understand the highlights of the "Series" before you try to understand a particular model within the series - sort of like "Required Reading."  Please make sure that you have read the KX-NCP Series Overview before continuing.

The KX-NCP500 system is the smaller of the two KX-NCP models.  It comes equipped with a Central Processing Unit called an “IPCMPR”, an integral Power Supply, built-in Ethernet network interface, a local programming interface, a Music-On-Hold jack, an External Paging jack and a SD Memory card containing the application programming data.  The KX-NCP500 leaves the factory with a 0x0 configuration. This means that it is pre-configured for zero Central Office Trunks and zero Extensions so that it may be customized to meet your exact requirements.

When configuring this product, one needs to think in terms of  Physical Resources and Virtual Resources.  Digital or Analog Trunks and Digital or Analog Extensions use Physical Resources (Circuit Cards).  IP Trunks and IP Extensions use Virtual Resources (License Keys).

USING "VIRTUAL" RESOURCES:
In order to use any of the IP Trunk or Extension features, the IPCMPR must be equipped with a DSP (Digital Speech Processor) module.  There are currently 3 versions of the DSP module available - a Light Duty, Moderate Duty and Heavy Duty (DSP4, DSP-16 and DSP-64).  Each DSP comes with some number of licenses pre-installed.

• DSP-4 comes pre-licensed for 4 trunks and 8 extensions;

• DSP-8 also comes pre-licensed for 4 trunks and 8 extensions;

• DSP-16 comes pre-licensed for 16 trunks and 32 extensions.

USING "PHYSICAL" RESOURCES:
The appliance is divided into two types of physical card slot bays - small cards on the left and large cards on the right.  There are 3 slots available for small cards and there are 2 slots available for large cards.


The list of available SMALL cards consist of:

• ISDN-PRI (23-Channel Primary Rate Interface)

• LCOT4 (4-Circuit Loop Start Central Office - a.k.a. POTS)

• DHLC4 (4-Circuit Digital Hybrid Line Card - a.k.a. Hybrid Extension)

The list of available LARGE cards consist of:

• T1 (24-Channel Basic Digital)

• DLC8 & DLC16 (8-Circuit & 16-Circuit Digital Line Card - a.k.a. digital Extension Card)

• SLC8 & SLC16 (8-Circuit & 16-Circuit Analog Line Card - a.k.a. Analog Extension Card)

• OPB3 (3-Device Option Board for UCD Messaging, DISA, Wakeup, Door Phones, etc)

The KX-NCP500’s maximum number of trunks cannot exceed 72 and the maximum number of extensions cannot exceed 68.

These maximum configurations however, can only be achieved by using a mixture of technologies.  Physical Resource bays are shared between trunks and extensions, so it becomes obvious very quickly that you cannot achieve maximum configuration for trunks and extensions simultaneously.  There are simply not enough physical card slots.

In an IP-only based configuration, plan on a maximum configuration of 8 SIP Trunks with 40 Proprietary Extensions.

The best candidates for the KX-NCP500 are those with high-speed cabling already in place (CAT-5 or faster, that want or need IP features and can operate within the Trunk and Extension limits listed above.    If this seems too confined, then you might want to look toward our KX-TDE100 or KX-TDE200 product instead.
