1-4 QUICK RESULTS
1. If you’re given two SPIDs by the phone company, enter just those numbers into
ZephyrExpress. This is the most common case in North America.
2. If you’re given just one SPID, don’t enter it: instead, use the PTP setting for Switch
Type.
3. If you’re in Europe you don’t have to enter anything. However, if you’re given MSNs
and want to limit which numbers ZephyrExpress will answer, enter them for those
numbers.
There are also several different types of ISDN switching devices that can be used at the
central office, each with a different set of protocols. You must know what type you have.
iISDN TIP!
If you have AT&T Point-to-Point protocol or European ISDN, the phone companymight provide just one number for the MSN or Directory Number.
These numbers, and possibly also the protocol, will be different for each ISDN circuit
you connect to. Since ZephyrExpress is portable, it’s likely to be used in multiple
locations. You can enter the complete information for each location into ZephyrExpress,
and recall its complete setting at the touch of a button.
Here’s a summary of circuit information. You may want to copy this form for each location.
Item 1 and 2 are required. Use just one set of numbers for item 3. Item 4 is optional.
