International ISDN Switch Types

International ISDN Switch Types
Cisco 700 series routers support most international switch types. International ISDN lines
generally use one of the following switch types:
•
EURO-ISDN (also known as NET3)
•
1TR6
•
TPH
•
Nippon Telegraph and Telephone (NTT)
Note

EURO-ISDN Switch Type

The EURO-ISDN switch type, also known as NET3, is used in Europe and parts of Asia,
including the United Kingdom, France, Germany, Singapore, and Taiwan.
Enter the show version command to verify that the software loaded on your Cisco 700
series router is ISDN Stack Revision NET3 2.10. If the correct software is not loaded on your
router, contact your customer service representative.

1TR6 ISDN Switch Type

The 1TR6 switch type is used in Germany. Enter the show version command to verify that
the software loaded on your router is ISDN Stack Revision 1TR6 2.10. If the correct
software is not loaded on your router, contact your customer service representative.

Multiple Subscriber Numbers with 1TR6

The 1TR6 lines can be configured for multiple subscriber numbers, usually referred to as
"extended addressing" in Germany. The line is usually assigned a group of eight sequential
directory numbers that can be used for the different pieces of terminal equipment used on
the ISDN line. These numbers are also used for allocation to the analog telephone port and
for call routing.
