X.1 21 AddressThis field determines the 
DNIC of the X.121
- = not selected
Thisis the X.121address for thedeviceas the
network sees it. This address is like a phone
number for a data network.
-The X.121 addresses are gotten from a
network just as DID numbers are gotten from
a CO.
-The PD-200 system requires X.121
addresses.
-This address is used in the processing of
X.25 call setup and verification.
-If the device is asynchronous, this address
must be 14 digits.
-If the device is a synchronous X.25 or if the
device is an ADMP, this address can contain
O-l 4 digits.-X.121 addresses are checked by data base
or the 
UCB/DCP. All X.121 addresses must
be different.
The 
DNIC is the first four digits of the X.121
address and will usually be 3110.
-311 = USA or country number: 0 = Telenet or
newtork number.
-The 
DNIC identifies the PD-200 network.
-If data calls will be made outside this
network (e. g., to Telenet), server numbers are
assigned by the network.
-Dashes cannot be entered in column 17.

-The default is either to make caller paid
calls or collect (reverse charge) calls.
-This is part of the facility field of the call
packet.
-If this field is enabled (Y), the default will be
the placement of paid calls. This port is billed
by the network for calls it originates.
-If disabled (N), the default will be collect
calls from this device.
-The terminal user may enter an 
R(requesting reverse charging) or a P

command and this will always override the
default.
-If this column is marked Y and column 42 is

most terminals do not make paid calls.

							TL-130400-1001Record Code AP:17.3 Record Code AP, Figure 17.3, defines the common
Data Systeminterface parameters for each APM (Asynchronous Packet
Asynchrouous PortManager). This record code is only used for asynchrouousports, and an entry for each APM must be found here.
There are three types of parameters that are defined for each of
the terminals or groups of terminals. They are:
.=.
. . . .l X.3 parameters
l Local parameters
l Optional subscription parameters
For normal applications, all terminals within the same group
(having the same 
DNIC and server number) have the same
parameters, depending on the terminal types.

.--If this parameter is enabled, the PAD will be_able to flow control the device when the PAD
falls behind in processing or if the amount of
characters buffered becomes too great due to
transmission condition or network slow-down.
-When the PAD sends a control-S, the
device stops transmission to the PAD. If the
device continues to transmit and overruns the
buffer, data is lost.
-When the PAD becomes unblocked, it
transmits a control-Q. It continues to
transmit this character until the device starts
sending data. Then the PAD sends an
indication to the connected device that it can
continue.
