Configuring and Managing Host-Based X.25 Links - Edition 5 (36939-90054)

Chapter 2 33
Preparing to Configure DTCs
Defining the DTC Connector Cards
called nailed devices. Printers and UPSs, as well as
devices that will be programmatically accessed, must
be nailed devices. Each nailed ldev number assigned in
NMMGR must be unique.
For host-based DTC management, you may have PAD
ports without ldev numbers assigned to them; hence
they are non-nailed devices. Non-nailed devices have
ldev numbers that are assigned from a pool of available
ldev numbers for the duration of the device connection
to the system.
Terminal and
Printer Profiles
Each port needs to be assigned a profile. A profile
defines a set of characteristics for a terminal, printer, or
another serial device. A profile can be of five types:
terminal profile, printer profile, PAD terminal
profile, PAD printer profile, or Host port profile.
See Configuring Systems for Terminals, Printers, and
Other Serial Devices manual for more information on
the characteristics determined by the profiles, anda list
of the profiles that are supplied in the sample
configuration file.
If the characteristics provided in the sample profiles
are different from those required by the terminals and
printers connected to your DTCs, then you can define
new profiles.
It is suggested that you use default profiles TR10D96
for direct connect terminals and PR18D96 for direct
connect printers or PR22D24 for HP printers with
status checking.For PAD terminals and printer, use the
defaults TR24PAD and PR26PAD, respectively. For
UPSs, use the default profile UP10D12.
The name of the profile can be up to eight characters
long and must start with a letter, followed by letters
and numbers. At any one time, up to 1024 profiles can
be configured per system.
