HOT TIP! When using an ISDN- equipped Xport on an analog (POTS) line you can
force the unit into POTS mode by pressing <
5> and <6> simultaneously when the
"Found ISDN card" message is displayed. This will shorten startup time.
THE ISDN CONFIGURATION MENU
This menu will not be present if the ISDN option is not installed, or if the ISDN was not 
connected at the time of start up. 
To configure the information about your ISDN circuit press
6
> key twice to highlight ISDN Setup. Now press 
• SPID
Users in the USA & Canada with Natl I- 1 and DMS Cust ISDN service should enter 
either of their SPIDs here. Your Telco should have provided you your SPID numbers 
for your ISDN circuit. The format is often XXXYYYZZZZ0101 (where XXX is the area 
code, YYYZZZZ is the 7 digit telephone number). 
If you are using ETS 300 (Euro ISDN, used throughout the world), INS 64 (used in 
Japan), or AT&T Cust PTP (sometimes used in the USA) ISDN service, you should 
leave this field blank. 
• MSN/DN
The use of these fields depends on the type of ISDN to be used.
Natl I- 1 and DMS Cust. Protocol (used in the USA and Canada): enter the 7- digit 
telephone number associated with the SPID entered above here. 
INS 64, or AT&T Cust PTP ISDN Protocol: leave this field blank.
ETS 300 (Euro ISDN): you may enter a "Multiple Subscriber Number" or "MSN" 
here. This is optional, and may be used if you are sharing the ISDN with another 
device. 
• Telco
This configures the Xport to operate with the particular type of ISDN line that may 
be connected. This is the ISDN "Protocol" or "Switch Type" and must be configured 
properly for the ISDN to function properly. ETS300 is used in most of the world 
including Europe, INS 64 is used in Japan, and AT&T Cust. PTP, DMS Cust. and 
Natl.I- 1 are used in the USA (Natl.I- 1 is used most commonly). 
Once you are done setting this item, the Xport will prompt you to reboot.
