DTC PAD Profile Field

Chapter 5 Preparing to Configure X.25 iX System Access

Table 4-4 "Terminal PAD Profiles" shows the usable DTC PAD profiles and their recommended usage. You must not use profiles 18, 45 and 50, even though they are available. All other numbers are blocked, and cannot be entered.

Table 4-4 Terminal PAD Profiles

Profile Definition Usage
1 PAD Test
Init profile
X.3 setting
Data Forward default		 Default terminal profile.

Does not need to be entered in the CALL User Data.

Direct replacement for the "Terminal" device type of releases prior to 12.0.

Ensures backward compatibility with DTC 2.0 to 10.5.
5 PAD Test
Init profile
X.3 setting
Data forward 3:127		 Used in data transfer.

Recommended for more performance of the Telnet path (X.29 SERVER profile compatibility) or for iX character mode applications which need to send each character to the host (for example, HPEDIT).

The profile loads the X.25 line with many, small packets each time the application needs a termination character other than CR.

The PAD must support 3:127.
9 PAD Test
Init profile
X.3 setting
Data forward 4:1		 Used in data transfer.

Recommended when you need more performance in iX character mode applications which need to send each character to the host.

The profile loads the X.25 line with many, small packets each time the application requires a termination character other than CR.
13 PAD Test
Init profile
X.3 setting
Data forward 4:2		 Used in data transfer.

Recommended for more performance in iX for VPLUS mode (NS/PAD compatibility) or for character mode applications which need to send few characters to the host.

The profile loads the X.25 line with many, small packets each time the application requires a termination character other than CR.

The PAD must support 4:2.
17 PAD Test
Init profile
No X.3 setting
Data forward default		 Used in data transfer.

Recommended if you don't want to change the hardcoded initial profile set by PAD Support when an application controls requires the setting of X.3 parameters other than echo, break or flow control.

The user must ensure that the editing characters are <BS> (ASCII 8) for backspace, and Control-X (ASCII24) for the line delete character.
33 No PAD test
Init profile
X.3 setting
Data forward default		 Used at connection initialization.

Recommended for more performance at the connection initialization, or if the PAD doesn't support the setting of multiple Set and Read, or isn't able to answer during the "PAD Test" sequence in accordance with X.29 recommendations. For example, for a PAD which answers with an X.29 PAD error at a parameter setting instead of setting the "error bit".

The PAD must support the X.3 setting needed by the applications.
35 No PAD test
No init profile
X.3 setting
Data forward default		 Used at connection establishment.

Recommended if the user wants to keep the profile set before connection initialization.

The PAD must support the X.3 setting needed by the applications.
37 No PAD test
Init profile
X.3 setting
Data forward 3:127		 Used at connection initialization and during data transfer.

The PAD must support the X.3 settings required by the applications and the 3:127 data forwarding.

The PAD must support the X.3 setting needed by the applications.
39 No PAD test
No init profile
X.3 setting
Data forward 3:127		 Used at connection establishment and during data transfer.

Recommended if you want to combine profiles 35 and 5.

The PAD must support the X.3 settings needed by the applications and the 3:127 data forwarding.
41 No PAD test
No init profile
X.3 setting
Data forward 4:1		 Used at connection establishment and during data transfer.

Recommended if you want to combine profiles 33 and 9.

The PAD must support the X.3 settings needed by the applications.
43 No PAD test
No init profile
X.3 setting
Data forward 4:1		 Used at connection establishment and during data transfer.

Recommended if you want to combine profiles 35 and 9.

The PAD must support the X.3 settings needed by the applications.
45 No PAD test
Init profile
X.3 setting
Data forward 4:2		 Used at connection establishment and during data transfer.

The PAD must support the X.3 settings needed by the applications and the 4:2 data forwarding.
47 No PAD test No init profile X.3 setting Data forward 4:2 Used at connection establishment and during data transfer.

The PAD must support the X.3 settings needed by the applications and the 4:2 data forwarding.
49 No PAD test
Init profile
No X.3 setting
Data forward default		 Used at connection establishment and during data transfer.

The PAD must support the X.3 setting needed by the applications.
51 No PAD test
No init profile
No X.3 setting
