Service Inspection Safety Procedures for the 3745, 3746-900, and  
Controller Expansion  
Important  
This procedure addresses the 3745, 3746-900, and the controller expansion. If one of these machines  
is not present, ignore the statement concerning this machine in the following procedure.  
Introduction  
A safety inspection procedure for the 3745, 3746-900, and controller expansion should be per-  
formed:  
Ÿ When it is inspected for an IBM agreement  
Ÿ When IBM service is requested and no service has recently been performed by IBM  
Ÿ When an alterations and attachments review is performed  
Ÿ When changes have been made to the equipment that might affect its safety.  
If the inspection indicates unacceptable safety conditions, the conditions must be corrected before IBM  
services the machine.  
Note: The correction of any unsafe condition is the responsibility of the owner of the equipment.  
The 3745, 3746-900, and controller expansion areas and functions checked through these procedures are:  
1. External covers  
2. Safety labels  
3. Safety covers and shields  
4. Grounding (earthing)  
5. Circuit breaker and protector rating  
6. Input power voltage  
7. Power control switch  
8. Power ON indicator.  
Note: The 3746-900 is powered ON and OFF through the basic 3745 frame, from a host, locally, or from  
the service processor.  
Hazardous voltages are still present in some areas of the 3745 and the 3746-900 when power is  
OFF.  
Steps 1 through 6 must be performed after power OFF as follows:  
Ÿ CB1s are switched OFF on the 3745 and 3746-900.  
Ÿ All equipment installed in the controller expansion (if present) is powered OFF.  
Ÿ Power supplies for the 3745, 3746-900, and controller expansion at customer's premises are  
switched OFF.  
Do not remove the power cord and ground strap .A/ of the controller expansion in order to maintain  
the ground protection (see Figure 0-2 on page xxi, Figure 0-3 on page xxii, Figure 0-4 on page xxiii,  
or Figure 0-5 on page xxiv).  
1 External Covers  
Check that:  
Ÿ They are all present on the 3745, 3746-900, and controller expansion.  
Ÿ They are locked with two kinds of locks: flat blade screw for the IBM access area and hex head  
for the customer access area (refer to the IBM 3745 Communication Controller Models 130 to  
17A, Parts Catalog, S135-2012).  
Ÿ They can be fully opened.

Ÿ Appropriate service clearance and access are provided around the frames with external covers  
opened.  
Leave all external covers opened to allow further safety inspection steps.  
2 Safety Labels  
Check that:  
Ÿ All the safety labels are at the places indicated by letters in “Safety Label Locations” on  
page lvii.  
Ÿ Each label is of the model corresponding to the letter as shown in “3745/3746-900 Safety Label  
Identifications” on page lx.  
3 Safety Covers and Shields  
Referring to the FRU location (Chapter 4), check that:  
Ÿ All the safety covers are present and secured with screws.  
Ÿ All the voltage terminal boards (TBs) are protected by a plastic shield screwed on top of the TB.  
4 Grounding (Earthing)  
Note  
In this book, "ground" means that the equipment must be connected to the earth.  
a Grounding on the 3745  
Refer to YZ110 for grounding jumper/contact locations.  
.
Check that:  
Ÿ Electrical continuity is assured between the frame ground and the terminals indi-  
cated on the ground distribution diagrams.  
Ÿ Electrical continuity is assured between the 3745, frame grounds, and to the premises  
grounding system, through the 3745 power cord.  
b Grounding on the 3746-900 and Controller Expansion to the Premises Grounding  
System  
Ÿ Electrical continuity is assured between their frame ground and premises grounding  
system through their power cords.  
Ÿ The 3746-900 is grounded to the 3745 via the power control cable (see Figure 0-1 on  
page xx).  
Ÿ For the controller expansion, an additional ground wire .A/ is also used (see Figure 0-2 on  
page xxi, Figure 0-3 on page xxii, Figure 0-4 on page xxiii, or Figure 0-5 on page xxiv).

Preface  
Preface  
About this Manual  
This MIP is a guide for fault isolation and repair of the 3745 Communication Controller. It is expected that  
the customer has used the .Problem Determination Guide, SA33-0096 or the 3745 Models A, Problem  
Analysis Guide (online document) prior to calling IBM for service. The MIP does not duplicate the tasks  
done by the Problem Determination Guide.  
The MIP gives the service representative information needed to:  
Ÿ Analyze problems or symptoms reported by the system user.  
Ÿ Restore normal 3745 operation.  
Who Should Read this Manual  
The person using this manual should be:  
Ÿ Trained to service the 3745 and 3746-900.  
Ÿ Familiar with the configuration of the system to which the 3745 is connected.  
Ÿ Familiar with the operation of the 3745, as described in the IBM 3745 Hardware Maintenance  
Reference, SY33-2066 and IBM 3745 Communication Controller Service Function, SY33-2069, which  
are part of this Maintenance Library.  
The intended audience for this manual are Product-Trained Customer Engineers (PT CE). The Product  
Support-Trained Customer Engineer (PST CE) is also expected to refer to this manual when he is required  
to perform the same tasks as the PT CE.  
How this Manual Is Organized  
This manual is organized as follows:  
Ÿ Safety information is at the start of the manual.  
Ÿ From Chapter 1 through Chapter 4, this manual is designed so that the information is presented to  
the user in the same order as he will require it during the majority of service calls. The user is told  
where to go next for each path through this part of the manual.  
Ÿ At the back of the manual are:  
– Appendix A, Maintenance Aids  
– Appendix B, Bibliography  
– Appendix X: Abbreviation list and glossary.

Chapter 1. START: How to Begin Troubleshooting  
Important  
Ÿ Your personal safety can never be over-emphasized.  
Ÿ You have been taught safety procedures since the earliest phase of your IBM training.  
Ÿ Your safety is part of every maintenance call.  
Ÿ You are the only one who can make a maintenance call safe.  
Ÿ Specific information can be found in “Product Safety Information” on page xvii and “Safety Label  
Locations” on page lvii.  
Start here when you use this manual to repair a 3745/3746 hardware failure.  
Ÿ Remember that the 3745/3746 are machines which are designed to be repaired while the cus-  
tomer is still using the operational areas. This is called Concurrent Maintenance. Before  
changing FRUs, you will be directed to ensure that you have the correct area of the machine  
ready for maintenance.  
Ÿ When a power supply is shared between adapters, the disabling procedures apply to both 'sus-  
pected' and 'associated' adapters.  
Ÿ During a call for service, it will normally be necessary to use the 3745 console. To log ON at a  
3745 console, proceed as directed in “Console Use for Maintenance.”  
Console Use for Maintenance  
001  
Is the 3745 a Model 17A?  
Yes No  
002  
The 3745 is a Model 130, 150, 160, or 170.  
The 3745 has password protection for functions controlled via a console. Several types of password  
exist for different activities. They are described in the IBM 3745 Advanced Operation Guide,  
SA33-0097.  
Obtain the maintenance password from the customer so that you can log on at the 3745 console  
(local, remote, or alternate). This password will give you access to Menu 3 Maintenance Func-  
tions, in addition to Menu 1 and Menu 2.  
If the 3745 failure prevents correct operation of the 3745 console, continue at “Selection Table” on  
page 1-4 .  
Log ON at the 3745 console as follows:  
1. Ensure that the customer is not using the console and that he has logged OFF. The channel  
enable/disable screen is displayed.  
2. Press F4: MOSS FUNCTIONS.  
3. The password screen is displayed.  
4. Enter the maintenance password.  
Note: Remember to log OFF the console and to re-IML the MOSS at the end of the service call.  
See “CE Leaving Procedure” on page 4-102 for more information.  
Continue with “Selection Table” on page 1-4.

Problems During Machine, EC, or MES Installation  
When installing a 3745, the 3745 Installation Guide, SY33-2067 should be used. When installing an EC or  
an MES, the supplied instructions should be used. It is possible that the task or diagnostic you were  
asked to perform during the installation detected an error, and you were requested to start troubleshooting  
using this manual.  
The primary purpose of this manual is to resolve problems that occur in an operational environment after a  
successful installation. That is, the machine has worked previously and is now failing.  
At installation time, or after an EC or MES is installed, it is possible that errors may occur due to condi-  
tions which would not exist in an operational environment.  
Ÿ Cables plugged incorrectly  
Ÿ Terminators missing  
Ÿ Mismatch between CDF and machine configuration  
Ÿ Mismatch between line characteristics and setups  
Ÿ Wrong address set  
Ÿ Top card connectors incorrectly installed  
Ÿ Loose cards.  
During your path through the MIP, you should remember these possibilities and, when the failing area is  
identified, check with the aid of the 3745 Hardware Maintenance Reference, SY33-2066 and YZ pages  
that these conditions do not exist prior to changing FRUs.  
Now, starting at the top of the “Selection Table,” work down until you find an entry that matches the  
symptom detected during the installation.  
Be sure to read “Exchange Precautions” on page 4-1 before removing any FRUs from this  
machine.

Reference Codes  
Using Reference Codes  
Reference Codes (8 digits) are always displayed at the rightmost position of the alarm on the 3745  
console. They are generated by the microcode which runs within the MOSS to provide an automatic  
analysis of box event records (BERs). This function is known as auto-BER and is part of the AUTOMAINT  
facility. Reference codes are also generated when diagnostics detect an error.  
If several alarms have been generated for the same problem, resulting in multiple reference codes, use  
the reference code beginning with BX, if any. If there are no BX codes, use the reference code given by  
the earliest alarm.  
To analyze a reference code to find the correct action to take, use the following procedure on the 3745  
console:  
1. From the Maintenance Functions on Menu 3, select the BRC function.  
The reference code screen will be displayed (see Figure 1-1).

Note  
When the microcode is a possible cause of the error, it is recommended that you check:  
1. If you have the highest level of microcode for your machine.  
2. That any applicable MCFs are installed.  
Your support structure will have this information.  
4. Hit F6 for additional information (on associated components and customer resources for TSS,  
HPTSS and ESS), and record the data for later usage.  
Note: If the CDF is not correct, this information can be wrong.  
5. When the FRU list is given, record the types and location, then use the “3745 FRU List” on  
page 1-53.  
If the reference code is reported as 'INVALID' or 'DUMMY', check that you have entered the same code as  
reported. If so, an error in the BER analysis or BER logging has occurred. Contact your support structure  
for assistance. See “Contacting Support” on page A-1.

FRU Group Table  
Using the MIP FRU Group Table  
Very important  
The MIP FRU group table lists the FRU groups likely to be called in this manual.  
This table covers MOSS/POWER FRU group for failures that prevent correct operation of the BRC  
function.  
Ÿ Each FRU group contains from one to three FRUs, listed by name and location.  
Ÿ The “1st FRU” is the most likely to be failing. The “3rd FRU” is the least likely.  
Ÿ Usually, only one FRU in an FRU group is failing, and you should try to reduce the FRU group  
to the one failing FRU.  
Ÿ If you can reproduce the 3745 failure, exchange FRUs one at a time until the failing FRUs are  
isolated.  
Ÿ As soon as you have recorded the FRU and location in the FRU Group, go to “3745 FRU  
List” on page 1-53.  
Always  
1. Ensure that the failing area of the machine is available for service.  
2. Consult the “Exchange Precautions” on page 4-1 before removing any FRUs.  
3. Check for loose cards, cables, and crossovers before exchanging FRUs.  
4. Run diagnostics after any repair action.  
5. Follow the 'CE leaving' procedure before returning the machine to the customer.  
The FRU group table starts on the next page.

Disabling Procedure 0150: Preparing LIC Type 1, 3, 4, 5, 6 for  
Maintenance  
Important  
Wait until the customer has completed  
deactivating the lines.  
Before using this procedure, ensure that the  
MOSS is online. Refer to “How to Put the  
MOSS Online” on page 4-105 for more infor-  
mation.  
Using the 3745 console, disconnect the line  
adapter from the NCP as follows:  
a. From Menu 3, select TSS Services  
by entering TSS in the selection  
area.  
You should have recorded the following informa-  
tion from the reference code and from the addi-  
tional information (PF6) for use during this service  
call.  
b. From the TSS Services screen,  
choose select/release by entering 1  
in the selection area. See  
Figure 1-11 on page 1-74.  
Ÿ FRU and location  
Ÿ Suspected adapter  
Ÿ Affected lines.  
c. In the input area, enter an S fol-  
lowed by the suspected adapter  
number. See Figure 1-12 on  
page 1-74.  
If necessary, use the LIC/Line address tables to  
find the affected lines. Refer to “LIC/Line Address  
Table” on page 1-73.  
d. Enter 3 in the selection area to  
choose Mode Control. See  
Figure 1-11 on page 1-74.  
e. On the Mode Control screen, enter

See Figure 1-13 on page 1-75.  
What you should do next:  
001  
If deactivation of all the lines driven  
by this line adapter was not done, a  
screen showing active lines will be  
displayed. If the customer is unable  
to deactivate these lines, request  
his approval to force deactivation for  
these lines.  
To force deactivation, enter F on the  
displayed screen.  
Continue with the next action only  
when all lines have been deacti-  
vated and the line adapter has been  
disconnected.  
– Ask the customer to stop the lines connected to  
the suspected LIC or pair of LICs for LIC type 5  
and 6. A LIC pair is an odd numbered LIC plus  
an even numbered LIC. Refer to the IBM 3745  
Connection and Integration Guide.  
– Run the automatic wrap test on the LIC unit  
(option 1) and the wrap test at tailgate level  
(option 2). Refer to “How to Run the Wrap Test  
(WTT) for TSS, HPTSS, or 3746-900” on  
page 3-15.  
Did you get the message: 'Wrap test com-  
pleted. The LIC is OK'?  
Yes No  
f. Enter 1 in the selection area to  
choose select/release. See  
Figure 1-11 on page 1-74.  
002  
g. Enter REL in the input area to  
release the disconnected line  
adapter. See Figure 1-13 on  
page 1-75.

Diagnostics  
Diagnostic Description  
3745 Diagnostics  
Diagnostic Monitoring  
Two groups of diagnostics run on the 3745:  
The controlled diagnostics are monitored by the  
diagnostic control monitor (DCM) and the  
command processor (CP).  
1. Automatic:  
IML/IPL checkout diagnostics including MOSS  
diagnostics.  
The diagnostic control monitor is loaded when the  
diagnostic utility program is selected from the  
3745 function menu.  
2. Controlled:  
Ÿ Internal function tests (IFTs)  
Ÿ Wrap tests  
It automatically restricts the diagnostic testing to  
the elements that are defined in the configuration  
data file (CDF) and disconnected from the NCP.  
Ÿ OLTs.  
Checkout Diagnostics  
Diagnostics are run during the installation proce-  
dure and when a fault is detected to isolate a  
field-replaceable unit that caused the failure. They  
are also executed after a repair is performed, to  
check that the hardware area is working correctly.  
They must be run before and after an EC or MES  
has been installed in the area concerned.  
The checkout diagnostics are designed to test the  
hardware of the CCU, IOC, Channel Adapter, CSP  
part of the line adapter, TIC, and the PCC card.  
For the CA, LA, and TIC, diagnostics are part of  
the microcode and are located in the ROS of the  
adapter itself. They run automatically at power  
ON time before IML.  
Diagnostics may be run in offline mode when the  
3745 is fully available or in concurrent mode. In  
concurrent mode, the diagnostic must be selected  
in the specific area and will run only in configured  
units. These units must be available at that time.  
The cyclic PCC checkouts run when the machine  
is powered ON and are successful when the  
power control and service mode indicators are dis-  
played.  
Errors During Diagnostics  
For the CCU and IOC, the diagnostics are located  
on the disk and run during IPL.  
When the MOSS diagnostic program detects a  
failure, a three-digit code is displayed on the  
control panel.  
For the CA, TSS, HPTSS, and ESS, they are also  
automatically run when the internal function tests  
are started.  
When the internal function tests detect an error, a  
reference code is posted on the 3745 console.  
For the TIC, the token-ring wrap test is automat-  
ically run at each TIC Open command from the  
NCP. This TIC Internal Lobe Media tests the ring  
up to the local wiring concentrator (IBM 8228), or  
up to the point where it is unplugged before the  
8228.  
If an error is detected, the MOSS analyzes the  
problem and presents a control panel code or a  
reference code.

How to Loop MOSS Diagnostics  
If an intermittent MOSS problem is suspected, the  
loop MOSS diagnostics facility can be used as  
follows:  
minutes of error free operation are sufficient to  
determine whether the MOSS is working satis-  
factorily. If an error is detected, a panel code  
will be permanently displayed. Therefore, go  
to “3745 Control Panel Codes” on page 1-15.  
Gentle vibration of the MOSS cables and  
cards (while the test is running), will locate  
most loose connection problems.

nostics mode.  
Selected diagnostics will run whatever the  
status of the adapter.  
For channel diagnostics, all the channel inter-  
faces must be disabled.  
Selected diagnostics will run if the adapter is  
available (ask the customer to disconnect the  
related resources), and only the sections or  
routines allowed to run in concurrent mode will  
be called without interfering the 3745 opera-  
tion.  
ODG must be used if conditions for concurrent  
maintenance mode are not met (no NCP or  
CCU running).  
For channel diagnostics:  
Diagnostics must be used in CDG mode if  
more than one CA is present and if CCU +  
NCP are running. If it is not the case, use  
ODG.

and PN 03F4301 (for Bus)  
1. Ask the customer to disable the channel  
related to the channel adapter to be tested  
with the Channel Wrap Test.  
Install them for interface A in the IN ROW  
(dark grey) and the CA terminators:  
2. Select option ODG or CDG from the mainte-  
PN 2282676 (for Tag)  
and PN 2282675 (for Bus)  
nance function menu.

5. Two models of wrap plugs can be used for  
this test:  
Ÿ Bus PN 03F4301 and Tag PN 03F4300  
Step 1 - Install the wrap plugs for  
interface A in the IN ROW (dark  
grey), and the CA terminators:

Table 4-8 on page 4-25 to remove the inter-  
face cables.  
Step 2 - Install the wrap plugs in the  
OUT ROW (light grey) and leave  
the IN ROW (dark grey) free  
(CA terminators have not to be  
used).  
8. When you requested by the diagnostic,  
remove the interface cables and install the  
wrap plugs.  
10. You will be asked to install the wrap plugs on  
the interface connectors B if the TPS feature

FRU Exchange  
Chapter 4. 3745 FRU Exchange  
This chapter is to be used to exchange a defined FRU. Use all section from the begining to the end, to  
determine:  
1. Where the FRU is physically located  
2. How to properly exchange FRUs  
3. How to test the machine  
4. What else must be done before returning the machine to the customer.  
Exchange Precautions  
1. Most of the 3745 FRUs can be exchanged in concurrent maintenance. Thus, it is very important that  
these procedures be followed when replacing any FRU in the machine.  
2. The control panel has voltage present even with the machine Powered OFF.  
3. Ensure that the 3745 is powered OFF before replacing any FRUs, except for hot-pluggable FRUs  
(LIC,MUX) and the separated power-controlled FRUs (FDD and HDD).  
4. Before starting the FRU exchange, ensure that the involved area has been disabled by the cus-  
tomer.  
5. The 3745 Communication Controller contains cards that are sensitive to electrostatic discharge (ESD).  
Use the ESD kit and store all cards in their protective packaging when you are not actually exchanging  
them.  
6. Procedures for exchanging FRUs are listed on the next pages. Use the list in alphabetical order.  
7. After the 3745 FRU exchange, go to “Action to Take After a Diagnostic Run or an FRU Exchange” on  
page 4-99.  
Attention  
Do not disassemble or attempt to remove FRUs from the 3745 until you have read the Safety Infor-  
mation manual, GA33-0400.  
Very important  
Ensure that the required area has been disabled  
before any FRU exchange  
if not, go to start page and follow the appropriate procedure.

This procedure analyzes the results of the diag-  
nostics or an FRU exchange and explains what  
must be done afterwards.  
008  
– Go to Step 018 on page 4-100.  
When MOSS diagnostics detect an error, a hex  
code is set on the control panel. The code can be  
decoded by using “3745 Control Panel Codes” on  
page 1-15.  
009

Glossary  
Glossary  
This glossary defines all new terms used in this manual.  
It also includes terms and definitions from the IBM Dic-  
tionary of Computing, GC20-1699.  
communication controller. A communication control  
unit that is controlled by one or more programs stored  
and executed in the unit. Examples are the IBM 3705,  
IBM 3725/3726, IBM 3720, and IBM 3745.  
adapter-initiated operation (AIO). A transfer of up to  
256 bytes between an adapter (CA or LA) and the CCU  
storage. The transfer is initiated by an IOH/IOHI  
instruction, and is performed in cycle stealing via the  
IOC bus.  
communication scanner processor (CSP). The  
processor of a scanner.  
communication subsystem. The part of the controller  
that controls the data transfers over the transmission  
interface.  
alarm. A message sent to the MOSS console. In  
case of an error a reference code identifies the nature  
of the error.  
configuration data file (CDF). A MOSS file that con-  
tains a description of all the hardware features (pres-  
ence, type, address, and characteristics).  
alert. A message sent to the host console. In case of  
an error a reference code identifies the nature of the  
error.  
control panel. A panel that contains switches and  
indicators for the use of the customer's operator and  
service personnel.  
autoBER. A program to automatically analyse a BER  
file.  
control program. A computer program designed to  
schedule and to supervise the execution of programs of  
the controller.  
automaint. A function that uses autoBER to isolate  
failing FRUs.  
box event record (BER). Information about an event  
detected by the controller. It is recorded on the  
disk/diskette and can be displayed on the operator  
console for event analysis.  
control subsystem (CSS). The part of the controller  
that stores and executes the control program, and moni-  
tors the data transfers over the channel and trans-  
mission interfaces.  
block multiplexer channel. A multiplexer channel that  
interleaves blocks of data. See also byte multiplexer  
channel. Contrast with selector channel.  
data circuit-terminating equipment (DCE). The  
equipment installed at the user's premises that provides  
all the functions required to establish, maintain, and ter-  
minate a connection, and the signal conversion and  
coding between the data terminal equipment (DTE) and  
the line. For example, a modem is a DCE (see  
modem.)  
byte multiplexer channel. A multiplexer channel that  
interleaves bytes of data. See also block multiplexer  
channel. Contrast with selector channel.  
Note: The DCE may be separate equipment or an  
integral part of other equipment.  
cache. A high-speed buffer storage that contains fre-  
quently accessed instructions and data; it is used to  
reduce access time.  
data terminal equipment (DTE). That part of a data  
station that serves as a data source, data link, or both,  
and provides for the data communication control func-  
tion according to protocols.  
central control unit (CCU). In the 3745, the controller  
hardware unit that contains the circuits and data flow  
paths needed to execute instructions and to control its  
storage and the attached adapters.  
direct attachment. The attachment of a DTE to  
another DTE without a DCE.  
channel adapter (CA). A communication controller  
hardware unit used to attach the controller to a host  
processor.  
high-performance transmission subsystem  
(HPTSS). The part of the controller that controls the  
data transfers over the high-speed transmission inter-  
face (speed up to 2 million bps).  
clear channel. Mode of data transmission where the  
data passes through the DCE and network, and arrives  
at the receiving communication controller unchanged  
from the data transmitted. The DCE or network can  
modify the data during transmission because of certain  
network restrictions, but must ensure the received data  
stream is the same as the transmitted data stream.  
high-speed scanner. Line adapter for lines up to 2  
million bps, composed of a communication scanner  
processor (CSP) and a front-end high-speed scanner  
(FESH).

initial microcode load (IML). The process of loading  
the microcode into a scanner or into MOSS.  
remote console may be connected to the (CC) through  
the switched network.  
initial program load (IPL). The initialization procedure  
that causes 3745 control program to commence opera-  
tion.  
scanner. A device that scans and controls the trans-  
mission lines. Also called line adapter.  
selector channel. An I/O channel designed to operate  
with only one I/O device at a time. Once the I/O device  
is selected, a complete record is transferred one byte at  
a time. Contrast with block multiplexer channel,  
multiplexer channel.  
input/output control (IOC). The circuit that controls  
the input/output from/to the channel adapters and scan-  
ners via the IOC bus.  
internal clock function. A LIC function that provides a  
transmit clock for sending data, and retrieves a receive  
clock from received data, when the modem does not  
provide those timing signals. When the terminal is con-  
nected in direct-attach mode (without modem) the ICF  
also provides the transmit and receive clocks to the ter-  
minal, via the LIC card.  
Systems Network Architecture (SNA). The  
description of the logical structure, formats, protocols,  
and operational sequences for transmitting information  
through a user application network. The structure of  
SNA allows the users to be independent of specific tele-  
communication facilities.  
line adapter (LA). The part of the TSS, HPTSS, or  
TRSS that scans and controls the transmission lines.  
Also called scanner.  
token-ring subsystem (TRSS). The part of the con-  
troller that controls the data transfers over an IBM  
Token-Ring Network.  
For the TSS the line adapters are low-speed scanners  
(LSSs).  
The TRSS consists of one token-ring adapter (TRA).  
token-ring adapter (TRA). Line adapter for an IBM  
Token-Ring Network, composed of one token-ring  
multiplexer card (TRM), and two token-ring interface  
couplers (TICs).  
For the HPTSS the line adapters are high-speed scan-  
ners (HSSs).  
For the TRSS the line adapters are token-ring adapters  
(TRAs).  
transmission subsystem (TSS). The part of the con-  
troller that controls the data transfers over low- and  
medium-speed, switched and non switched transmission  
interfaces.  
line interface coupler (LIC). A circuit that attaches up  
to four transmission cables to the controller.  
low-speed scanner. Line adapter for lines up to 256  
kbps, composed of a CSC card.  
The TSS consists of up to six low-speed scanners  
(LSSs) associated with the LICs units (LIUs), through  
serial links (SLs).  
maintenance and operator subsystem (MOSS). The  
part of the controller that provides operating and ser-  
vicing facilities to the customer's operator and the IBM  
service representative.  
two-processor switch (TPS). A feature of the channel  
adapter that connects a second channel to the same  
channel adapter.  
NetView. An IBM licensed program used to monitor  
a network, manage it, and diagnose its problems.
