ISDN Tip
ETS 300 users should disregard all references to SPIDs. Euro ISDN does not have SPIDs (you
lucky souls)!
IMPORTANT
If your line status shows “Wait” at least one of your SPIDs is incorrect or your ISDN Protocol
setting is incorrect! In this case, check the SPID. For a list of known working SPIDs by tele-
phone company, see the Appendix.
Notes on SPIDs
Incorrectly entered SPIDs are the most common problem USA users have placing ISDN
1.
calls. Compare the SPIDs you have entered with the SPIDs provided to you by the phone
company to be certain that you have entered them correctly. Do not add anything to your
SPIDs.
Note that there are no hyphens, dashes (-), or spaces in SPIDs, so the system will not

allow you to enter any non-numeric characters. If your installer has included them in the
SPID, ignore them.
If you have any questions about your SPIDs, call your phone company.

If you have AT&T Point-to-Point or ETS300 Euro-ISDN Protocol mode, you should

not enter anything in the SPID fields.
MSN – Multiple Subscriber Number
This item, if required, must be configured from the Web interface. Used only when you are using
the ETS 300 Euro-ISDN Telco mode and another ISDN device is sharing the line with the
Nx12. MSN1 corresponds to the first B channel. This is simply one of your assigned telephone
numbers. Normally, for ETS 300 these should be left blank.
DN – Directory Number.
This item, if required, must be configured from the Web interface. When you are using an
ISDN protocol other than ETS 300 or AT&T Cust. PTP, you must enter the ‘Directory
Number’ (DN) here. This is simply the telephone number associated with the channel.
Tip
Each directory number will correspond to one SPID. You must enter them to reflect this
relationship. The DN corresponding to SPID1 must be entered as DN1 while the DN corre-
sponding to SPID2 must be entered as DN2.
If you experience problems only with incoming calls check your DNs. Normally 7 digits
should be entered, but you might need to enter 10 digits.
In some cases lines in a hunt group will require that the same (primary Listed Directory
Number) be entered for all lines that are part of the hunt group.
