Calls Using Address Extensions

You can specify the following additional components of a numeric address: an OSI NSAP address, a non-OSI address extension, and Call User Data.

To specify an OSI NSAP address, enter a period, an N (uppercase only) and a period before the NSAP address:

PAD: call 21521122334455.N.4910002233

To specify a non-OSI address extension, enter a period, an X (uppercase only), and another period:

PAD: call 21521122334455.X.7777

Specify Call User Data by preceding the data with space followed by a tilde (~). For example:

PAD: call 21521122334455 ~cud

The pad program automatically adds the X.29 protocol identifier (01000000) to the front of the data you specify.

If you enter a pad command using call user data in a c shell, you must escape the tilde by preceding it with a back-slash "\":

> pad 21521122334455 \~cud

You can also specify Call User Data in conjunction with an OSI or non-OSI address extension. For example:

PAD: call 21521122334455.N.4910002233 ~cud
