ISDN2e
This type of ISDN is supplied as a single line which has the capacity to carry two telephone calls. The service is usually delivered to the customers site as a single termination point (RJ45), and needs to be connected to the ISDN2 Trunk Port of a telephone system to be able to work. A single ISDN2e phone line provides two channels, so that means two simultaneous calls can be made at any one time. Multiple ISDN2e lines can be used together to increase the capacity of simultaneous calls, but each ISDN2e phone line will need to be connected to it''s own ISDN2e Trunk port on the telephohne system.
DDI numbers can be allocated to ISDN2e phone lines, so for expample you could have two ISDN2e phone lines (4 channels) and a blcok of 10 or 20 DDI telephone numbers. This would mean that a small business with 15 extensions would be able to give each extension it's own telephone number, so when a call is made to that phone number, the phone system sees the number being called and can route the call to a particular extension. Of course, with only 2 Lines (4 channels) only 4 calls inbound or outbound could be made at any one time, no matter how many individual DDI numbers were allocated to the lines.
ISDN2e telephone lines tend to be used for smaller phone systems were only three or four ISDN2e lines are required (6-8 channels), so the KX-TDA15 or KX-TDA30 phone systems should provide adequate capacity for both lines and extensions for small to medium businesses that want to take advantage of ISDN services. If a business requires more than eight simultaneous calls they should consider ISDN30e phone lines.
