How to Use the Data Card in a NEC PBX

The NEC NEAX 2400 PBX system is designed to be part of both simple and complex phone system configurations. The PBX system is designed with four internal data or I/O card expansion slots for use in expanding its system capabilities. Data or I/O cards give the NEC PBX system the ability to handle more phones in the system, and phone extensions per phone. Once a data card is installed into the NEC PBX, it is automatically available for use by the system.


Instructions

1) Unscrew the six screws on the back panel of the NEC PBX to remove the panel. Once the screws are removed, lift the back panel upwards and off.

2) Insert the data card into one of the four empty data card slots on the center left-side of the PBX's main board, aligning the metal contacts on the data card with the metal contacts in the card slot. Push the card in gently until it snaps into place.

3) Replace the back panel onto the unit, sliding it downward into place. Then, replace and tighten the back panel screws

SIP Trunking - The Key Questions Answered

Q: What is SIP Trunking?This is a way to link your PBX to a phone network with the help of a data network as well as the protocol that is called SIP which stands for Session Initiation Protocol.

Q: What are the Benefits? You are provided the opportunity of making calls at a cheaper rate, with cheaper infrastructure and you will not be integrated with any telecoms circuit.

Q: What's the call quality like? Once SIP trunking is properly set up the quality of the call is as good as or even better than your regular phone service. On the other hand if it is not set up by an expert you will have packet loss and latency in your connection which will affect your call quality negatively.

Q: I'm a consumer. Could I benefit? If you have a standard internet connection as a consumer you will not get a good quality call signal and so the reduction in cost won't be to your advantage. If you don't mind having fluctuations in your call quality though you can use this method but ensure you have a back up if it fails miserably.

Q: Can SIP Trunking deliver a business-class service that's as reliable as my existing setup? In order to get great quality, you will need to get a minimum latency, low jitter and minimal packet loss network to connect your PBX to the provider of your SIP trunking services. Your best bet to ensure good call quality will be an ISDN30 circuit along with an internet connection that is dedicated solely for this purpose. This way the amount you save will be an advantage as you will have clear call quality.

Q: Will SIP Trunking be compatible with my existing PBX? Once the PBX can understand the signals of your SIP trunk you should have no problems.

Q: How should I choose which provider to use? By looking for ones that offer business class services, continuous telephone support (24/7) and multiple telecoms carriers.

Q: Is SIP Trunking a fad? This is a definite no. Many big companies use SIP support for their products and services. These companies include Cisco, Verizon, Microsoft, Mitel, Siemens, Avaya, Panasonic, Nortel and Samsung. These are just a few as increasingly more and more businesses are replacing their ISDN's with SIP.

Q: How much can my business save by switching? There are a number of factors that affect the answer to this question. Some are the quantity of calls made, when the calls are made, which numbers are being called and how long the calls last. Other factors include the minimum call charge as well as the rental costs of the ISDN circuits and the length of the contract.
Your best bet for finding out how much you could save is to find a SIP trunk provider and send them your most recent phone bill. They will use this to provide you with an estimate of how much you could save for your particular business.

Q: How long does it take to switch to SIP Trunking? It can take as long as it will take you to get an internet connection of 2mbps for less than 30 channels and for in excess of 30 channels it will take as long as it takes for you to get a 10mbps internet connection.
