The backbone conduit infrastructure which interconnects secondary infrastructures to form a single logical laboratory-wide communications conduit system.
A modular, high-quality performance, real-time operating system designed
specificially for embedded microprocessors from
Integrated Systems, Inc.
pSOSystem is made up of the following components:
pSOSystem,
pSOS+,
pNA+,
pREPC+,
pROBE+,
pHILE+,
pRPC+,
XRAY+.
A real-time multitasking kernel.
Provides network services for pSOSystem. pNA+ allows real-time tasks
to communicate with any system supporting TCP/IP protocols.
A re-entrant C run-time library for pSOSystem.
A kernel debugger for pSOSystem. Can be used in conjunction with
XRAY+
for source level debugging over a network.
Proivides high-performace file management for pSOSystem. It also
provides MS-DOS file format compatibility.
Provides Remote Procedure Calls (RPC) and Network File Systems (NFS)
for pSOSystem tasks.
Router
.....
Site Communications Infrastructure
The secondary communications infrastructure system logically
interconnects buildings within a specific geographical area (i.e.
N15 campus) or the various communications locations within an
accelerator (i.e. LEB complex). This design defines all communications
components within the specified site but no closer than five (5) feet
from the perimeter of any given building.

T1
T1 is a Time Division Multiplexing Standard used throughout the data
communications and telephony industry. It is a byte serial interface
operating with a 125 micro second time-slot. Within this 125 micro
second period, 24 bytes of data + 1 bit for synchronization are
transmitted. The bit rate is therefore ((24 * 8)+1) / 0.000125 = 1.544
M bits per second.
T1 is used by the telephone industry to transmit digital telephone
calls. Each voice circuit occupies one byte in each 125 micro second
time slot. Thus a T1 can carry 24 phone calls.

A source level debugger for real-time systems. XRAY is developed
by Microtec Research, Inc. It is then ported to various platforms.
XRAY+ is knowledgeable of the pSOSystem
real-time environment. It is provided by the
Software Componets Group
of Integrated Systems, Inc.
XSNMP
A public domain program for monitoring a set of network devices.
XSNMP originated from a simple program which used ICMP ECHO (ping) packets
to verify if systems were up or down. It still uses that protocol for that
purpose, however further capability will contine to be added as time permits
using the SNMP protocol.
The ping ability will be retained, however SNMP will allow the program
eventually to monitor things like network traffic through an interface,
figure out the network topology by itself (which it currently does), etc.
