Section 5 ISDN

Service Profile IDentification numbers (SPIDS) are only required with the Zephyr when
you are using the National I- 1 or DMS Customer functional ISDN protocols in the USA.
This number is given to the user by the phone company and must be entered into the
Zephyr in order for the connection to function. SPIDs usually consist of the phone
number plus a few prefix or suffix digits. There is frequent confusion between telephone
numbers and SPIDS, even among Telco personnel. While the SPID frequently includes
the corresponding phone number, this is not necessarily the case.
If you are using the National I- 1 or the DMS Custom functional protocol, your Telco
service representative must give you one or two SPID numbers. You should get one
SPID for each B channel you ordered.
Upon power- up, connection of the ISDN line, or reboot, the Zephyr and the Telco
equipment go through an initialization/identification routine. The Zephyr sends the
SPID(s) and, if it is correct, this fact is signaled by the network. Thereafter the SPID is
not sent again to the switch.
Realtors remind buyers that the three most important factors of real- estate success are
Location, Location, and Location! We want to remind you that the three most important
factors to ISDN success are: Get the SPIDS,
GET THE SPIDs , please
get the spids!
You must have this number, and it must be 100% correct, or the system won’t work.
Don’t let the installer depart without leaving them. You’ve been warned!
ISDN TIP!
In an emergency, to save a remote, you can sometimes get a
line working without the proper SPIDs by dialing into it. This
fix is only temporary and the line will fail to initialize next time
the Zephyr is booted
ISDN TIP!
If you see WAIT as your line status your SPID is incorrect. In
this case check the SPID. For a list of known working SPIDs
by telephone company see the Appendix.
