ISDN TIP!

If the line status shows Ready & Ready and you can make calls, but cannot receive calls,

check the following:

-Is the Telco selection in the third TEL menu set correctly? If you have DMS Cust. ISDN

(USA & Canada only) and your Telco is set to Natl. I-1 you may be able to place calls

outgoing calls only.

-Check your MSN/DN 1 & 2 entries in the second TEL menu. If incorrect numbers are

entered here, you won’t be able to receive calls If you are in the USA these are required.

Enter the correct DNs.
