Installing the Network Layer (I/O Processes)
The OSI/TS subsystem depends on a communications I/O process to provide Network
Layer services. This subsection discusses some issues you need to consider when
installing the Compaq access methods that provide I/O processes (Network Layer
services) to OSI/TS.
OSI/TS uses two standard Compaq products to provide network services:
•
X25AM
•
TLAM, for K-series systems and pre-G06 S-series
•
PAM, for G06 and above S-series systems
Installation of these access methods requires changes to your current operating system
image. TSP processes assign I/O processes according to the NSPDEVICE subdevice
attribute.
A TSP process can interface with multiple I/O processes (NSP processes) one TSP
process can interface to multiple X25AM NSP processes, while another interfaces to
multiple TLAM (for D-series and pre-G06 releases, or PAM, for G06 and above
releases) NSP processes. However, two or more TSP processes cannot interface to the
same TLAM (for D-series and pre-G06 releases, or PAM, for G06 and above releases)
NSP process.
To configure a TSP process to interface with multiple NSP processes, specify the name
of each NSP process using the NSPDEVICE attribute in the ADD SU command for two
or more OSI/TS subdevices, then make sure the application specifies the desired OSI/TS
subdevice. An example of this type of configuration is given in the subsection Single
TSP Process Supporting Multiple X25AM Lines, later in this section.
Figure 3-1
shows a single TSP process supporting multiple NSP processes.
