Communications Processors

The Comten

3690,

above, represents the top of the Comten IBM

3705-replacement

line.

Its basic 256K bytes

of

is

expand-

able to over four megabytes and, unlike the 3705, peripherals such

as disk and magnetic tape storage are supported.

MANAGEMENT

SUMMARY

Comten delivered its first

IBM

plug-compatible com-

munications processor shortly after the initial IBM 3705

announcement in 1972,

and

has since become one

of

the

leading manufacturers

of

front-end and remote com-

munications processors.

Comten's current IBM-compatible products (the 3650 II,

the 3670 II,

and

the 3690) closely parallel the operation

of

'

IBM's 370X Communications Controllers, as does the

Comten software. As a result, implementation

of

a

Comten

36XO

running the Comten Emulation

or

CNS

software requires no modification

to

the IBM host's tele-

communications access method

or

application programs.

When running Comten

NCP,

the 360/370 host's access

method must be VT

AM

or

TCAM,

as required for IBM's

NCP.

In

response

to

IBM's entry into the distributed processing

market, Comten announced

and

subsequently delivered

Release 1

of

its unbundled

Data

Switching System (DSS)

software. This modular software package permits any

CONFIGURATION

The Comten 3670 II and the Comten 3650

II

are based on

the same hardwired processor with a memory cycle

of

650

nanoseconds and a 16-bit word. The 3650 is a stripped-down

version

of

the 3670 and supports a reduced number

of

direct

host connections, communications lines,

and

memory

capacity.

The Comten 3690 has a microprogrammed processor with a

memory

cycle

time

of

520

nanoseconds. Architectural sophis-

tication enables the

3690

to

operate from three

to

six times

faster than the 3650/3670.

The most notable architectural changes that contribute

to

the speed enhancement

of

the 3690 are: the processor logic

network of distributed systems. DSS supports SNA/

SDLC capabilities similar to those developed by IBM for

its

3705

II under ACF/NCP.

With over

1,000

36XO's

already delivered and operating,

Comten's customer following has grown substantially.

Comten offers several features which are not presently

available to IBM

3705

users. These include support for a

variety of peripherals, and stand-alone operation.

The 3670 and 3690 offer proportionately increased

memory capacity, line handling capability, and support

for more channel-attached hosts than the

3650.

Comten

estimates that the

3690

operates from three to

six

times

faster than a comparably configured

3650

II and

3670

II.

Additionally, Comten machines reportedly offer a

memory

cycle

time which

is

40

percent faster than that of

the

3705.

The version II models of the

3650

and

3670

were

first

delivered in

1976

and offer enhanced semiconductor

memory and line handling capacity over their predecessor

models.

In June

1979,

Comten

was

acquired by NCR, Inc. follow-

ing several months of heated negotiations during which

Amdahl quickly entered, and exited, the bidding. Much

industry

speCUlation

has been devoted to how the acquisi-

tion

will

affect future Comten product development. The

new NCR subsidiary (which incidentally grossed about

$50

million in

1978)

will undoubtedly continue in

its

IBM-compatible pursuits (which have been extremely

lucrative), but may also now focus some of its develop-

ment effort towards NCR-compatible communications

equipment.

USER REACTION

From

the

DAT

APRO

Survey

of

Communications

Processor users conducted in the fall of 1978,52 Comten

users were identified.

It

is

noteworthy that the group of

Comten users comprised the second largest group of

respondents to this survey (next to the group of IBM

3704/3705 users). The Comten ratings represented a total

of

10

1 processors in operation, or roughly two per

respondent.

Of the

52

users,

36

had Comten

3650

processors. The

balance

(16)

were

3670

users. Each

3650

was

handling an

average of

75

communications lines. The ratings

given

by

these users were

systems. Comten

will

also produce custom

as

required. Table

The

36XO

at a Glance, distinguishes the characteristics

of

each

36XO.

Software

to

operate the

36XO's

as

front-ends, remote con-

centrators, and

as

stand-alone communications processors

is

included with the equipment. The Emulation package

permits the

36XO

to function as an IBM 370X

or

as an IBM

370X emulating an IBM 270X.

The Communications Networking System (CNS) package

has all

of

the capabilities

of

the Emulation package plus the

ability for multiple Comten processors within a network to

communicate with each other.

The Network Control Program (NCP) relieves the host

processor

of

the bulk

of

network control functions and

is

comparable to IBM's NCP. The host access method, when

operating NCP

in

the Comten processor, must

be

IBM's

TCAM or VTAM.

The Data Switching System (DSS) augments NCP and CNS

to enable the Cornten processor

to

efficiently operate as a

distributed network nodal processor, conforming to the rules

established

by

IBM's System Network Architecture (SNA).

Asynchronous

lines

up to 19.2K bps, and synchronous lines

up

to

56K bps are supported

in

either half- or full-duplex

mode. Major protocols supported including Teletype, BSC,

CNS trunkline (Comten's internal, BSC-like protocol), and

SDLC.

Comten

3650

II

The

3650

II

is

offered

in

four basic models. Two

of

the models

are intended for

use

as

a front-end processor and two

of

the

models are intended for

use

as

a remote concentrator. All

models include the base cabinet with the 650-nanosecond

processor, 64K bytes

of

memory, the Integral Program Load

Device and two Direct Storage Access channels. The two

front-end processor models, the 3650-C3 and the 3650-D3,

include one IBM Channel Interface Adapter, which provides

a direct storage access connection with the host computer

system. An optional second channel

is

available for attach-

ment

of

either peripherals requiring a direct channel inter-

face or a second IBM Channel Interface Adapter. The latter

can

be

attached to the same host

or

to another host com-

puter. The

C3

and D3 models also include a Communica-

tions Interface Module that

will

permit the attachment

of

up

to

eight Modem Interface Modules (MIM) to the system.

Each Modem Interface Module

will

support up to

16

com-

munications lines.

The base cabinet

of

the 3650-C3 has space and electrical

interfaces to accommodate three Logic Modules. (A Logic

Module

is

a deck

of

up to

70

circuit boards occupying about

23

x 6 x 9 inches

of

space within the cabinet.) Three of the

four types

of

attachable MIM's require the space

of

one

Logic Module. Three

of

these MIM's,

in

any combination,

can be installed on the 3650-C3 models with each

MIM

supporting up to

16

lines. A fourth type

of

MIM, the DLC-

MIM, occupies one-half

of

two adjacent Logic Modules.

The basic 3650-C3 therefore can accommodate only two

of

the DLC-MIM's. Physical considerations prevent the third

Logic Module from being used when two DLC-MIM's are

attached.

An

alternate configuration permits one DLC-

MIM

and one

of

the other three types

of

MIM's to be

It

should be noted that, except for ease of installation, all

of the other ratings for the 3650 were above the average

readily determined what

percentage of these processors were Model I or Model II,

but judging from the period

of

time that they had been

operational, it would appear to

be

about half and half.

Most

of

the respondents were using the 3650 to front-end

IBM and compatible mainframes, and most were operat-

ing in IBM 270X emulation mode. About a third

of

the

processors were operating in NCP mode. Only two of the

users indicated that they were employing a 3650 in a

remote concentration capacity.

The ratings given by the

16

3670

similar to those given for the

3650,

although some

of

the

ratings were slightly higher or lower. Incidentally, the

average number

of

3670's was 148.5, the highest average capacity for all

of

the communications processors rated in the survey,

more Logic Modules are required, Module Controllers are

employed.

The basic 3650-E3 and the 3650-F3 remote concentrators do

not include a Charmel Interface Adapter; however,

up

to

two

adapters can

be

optionally attached to each system. Included

in the basic 3650-E3 and the 3650-F3 are a BSC-MIM and

a Line Interface that will support eight full-duplex communi-

As with the 3650 processors, about half of the 3670's

appeared to

be

Modell,

and half Model

2.

Almost all

were operating in IBM 270X emulation mode. About a

quarter

of

the respondents indicated that they were using

at least one

of

their processors in a remote concentration

capacity.

Many

of

the Comten users indicated that they had experi-

enced major difficulty with communications lines and

modems, but it could not

be

determined whether or not

this was related to the processor operation_ Several

of

the

users stated they had encountered problems with the

Comten software, but based on the ratings,

3_0

and 3.1,

these problems were apparently either minor, or had been

resolved with subsequent software releases.

Based on the overall ratings, Comten enjoys a satisfied

user base. Both machines rated well above the average in

almost all criteria.D

~

The three front-end base models, the 3670-EI,

FI,

and

GI,

have 11, 19, and

27

Logic Modules, respectively. A Logic

Module is the space available to mount one rack

of

PC

boards. When more MIM's are required than can be con-

tained in the base configuration, expansion cabinets (Module

Controllers) are necessary. Module Controllers are avail-

able

in

4 models containing

6,

12, 18, and

24

Logic Modules.

Each controller comes

in

a single processor version and a

dual processor version. The dual processor version permits

two 3670's to

be

attached to the controller. The net effect is

that two front-end processors can have access

to

the com-

munications

lines

that are attached to the controller.

The two remote concentrator systems

(HI,

JI)

include one

BSC-MIM with one trunk line interface that accommodates

up to 8 full-duplex lines at speeds up

to

56K bps. One addi-

tional Communications Interface Module can

be

optionally

added, permitting a total

of

24

MIM's

or

up to 384 com-

munications lines. Two Direct Storage Access Chaunels are

"-

available

on

the remote system for attachment

of

up to

16

direct access peripheral controllers when a Block Multiplexer

is attached

to

each Direct Storage Access Channel. The basic

3670-HI has

12

Logic Modules. When adding more MIM's

than can be contained in the base configuration, the Module

Controllers, as described above, are used.

Comten

3690

The Comten

3690

is

offered in

five

basic models. All models

include a microprogrammed processor with dual-odd/ even

storage

access,

an Integral Program Load Device,

256K

bytes

of

520-nanosecond memory, and one Communica-

tions Adapter (CA). The CA accommodates up to 8 Modem

Interface Modules and associated Line Interfaces

to

support

up to

128

communications lines. Up to three additional CA's

can be optionally attached permitting physically attaching

up to

512

communications lines per

3690

system. Since the

basic models include space for two, three,

or

seven Logic

Modules, Module Controller expansion cabinets are pro-

vided to accommodate the attachment

of

MIM's and Line

Interface. The Module Controllers are available to handle

Logic Module requirements

of

6, 12,

18,

24,

30

or

36

Logic

Modules. Each

of

the controller sizes has a version that

permits dual 3690's to access the controller and the lines

attached to that controller.

The basic

256K

bytes

of

memory can be expanded

to

4096K

bytes

by

the attachment

of

up to

15

Memory Modules; each

module contains

256K

bytes

of

memory.

four DSACs with one

of

the DSACs having a Block Multi-

plexer Channel attached. The Block Multiplexer has the

capacity

to

accommodate up

to

eight peripheral controllers.

The remaining three

DSAC's

can optionally receive Block

Multiplexer

Channels

or

Integrated File

Adapters

(for

multiple disk attachment). This model includes space for

three Logic Modules in the

base

cabinet.

The 3690-B4

is

intended

to

function as a remote communi-

cations processor

and

does not include any Direct Storage

Access Channels. This model includes space for three Logic

Modules in the base cabinet.

The 3690-C4, D4,

and

E4 are intended

to

function as front-

end processors. All three models include four Direct Storage

Access Channels. The 3690-C4 also includes one Channel

Interface Adapter for direct attachment

to

the host. The

three remaining DSAC's can be used to attach up

to

three

additional Channel Interface Adapters, up

to

three Block

Multiplexer Channels,

up

to

three Integrated File Adapters,

or

any combination

of

the three feature attachments.

The 3690-D4 has a Channel Interface Adapter Base attach-

ment

to

one

of

the DSAC's. This CIA Base can support

attachment

of

up

to four Channel Interface Adapters, still

leaving three DSAC's available. The three DSAC's are

restricted

to

attachment

of

Block Multiplexers

or

Integrated

File Adapters. The basic 3690-D4 includes one

mM

Channel

Interface Adapter.

The 3690-E4 includes two CIA Bases, each ahle

to

accom-

modate up

to

four host attachments

or

a system total

of

eight. One

of

the CIA Bases includes

an

IBM Channel Inter-

face Adapter as part

of

the basic configuration. The two

remaining

DSAC's

can

be

used for Block Multiplexer

or

Integrated File Adapter attachment.

CONNECTION TO HOST COMPUTER

The 3650 supports

up

to

two direct host connections; the

3670,

up

to

four;

and

the 3690,

up

to

eight. The Channel

Interface

Adapter

controls byte transfers between

the

Comten processors

and

the multiplexer channel

on

an

IBM

host computer. Subchannel addresses from 1

to

256 are

supported. When the Comten processor

is

emulating

an

IBM 270X,

an

Emulator Identifier feature

is

required along

with the Channel Interface Adapter.

TRANSMISSION

SPECIFICATIONS

Asynchronons lines

up

to

19.2K bps, and synchronous lines

up

to

56K bps are supported. EIA

RS

232C, current loop,

wideband,

and

DDS

interfaces are supported in either

full-

or

half-duplex mode. Notable among the protocols

supported are binary synchronous communication (BSC),

SDLC,

and

CNS

trunkline. The latter

is

a BSC-Iike protocol

used internally

on

Comten networks.

Each type

of

line interface requires specific Modem Inter-

face Module

and

Line Interface features. These features are

attached

to

the system Communications Interface Module.

Table 2, Communications Line Interfaces and Modem Inter-

face Modules, lists the features required

to

support the

various types

of

communications lines. Throughput limita-

tions are noted by the number oflines each

MIM

will support

for a given type

of

interface, despite the physical capability

of

attaching 16 lines per

MIM.

SOFTWARE

Currently, four major software packages are available, for

operating Comten

36XO

systems. The Comten Emulation,

Communications Networking System (CNS),

and

Network

Control Program (N CP) packages are available

at

no

addi-

tional charge. The

Data

Switching System (DSS)

is

available

on

an

unbundled basis.

Emulation

Comten Emulation permits the

36XO

to

operate as

an

mM

3704/3705 controller, including the capability

to

emulate

an

IBM 270X.

In

addition

to

permitting one Comten

36XO

to

replace multiple 270X/370X devices attached

to

one host,

the

36XO

can be connected

to

multiple hosts. Emulation also

supports terminals

that

are

not

compatible with the 270X

and 370X.

Emulation consists

of

a module for each terminal-type

requiring support

and

a string

of

special purpose programs

such

as

TILS,

ABRD,

MAF,

and DIAL. TILS, Terminal-

Initiated Line Switching, assigns the appropriate host sub-

channel address

that

is

associated with a particular applica-

tion. The assignment

is

based upon the terminal operator's

description

of

the linkage required. TILS includes a feature

that will automatically reroute transactions

to

a backup host

when the primary host

is

unavailable. ABRD, Automatic

Baud Rate Detection, enables multiple start/stop terminals

with different speeds

and

data-link control procedures

to

share the same line

to

a Comten front-end processor.

ABRD

is

used in conjunction with TILS. When a terminal operator

initiates a linkage under TILS, it

is

ABRD

that determines

the terminars speed

and

data-link control. SILS, Site-

Initiated Line Switching, under the control

of

the front-end

processor's operator, performs the TILS function for dedi-

cated lines.

MAF,

Multiple Access Facility, relieves the host

of

the polling function for IBM 3270 systems

and

permits

the terminals

to

select applications in any host computer

attached

to

the Comten front-end processor.

DIAL,

Auto-

matic Dialing, handles

up

to

16 phone lines for host-

originated calls.

Emulation also provides utility programs for monitoring

and

maintenance, on-line terminal testing, console

I/O,

and

on-

line system generation.

Communications

Network

System (CNS)

When there

is

a need for two

or

more Cornten processors

to

communicate with each other, within a network, the

Emulation software package

is

replaced with the Communi-

cations Networking System (CNS). While pedorming all

of

the functions

of

Emulation, CNS also enables a Comten

processor functioning as a remote concentrator

to

transmit

to

and receive from a Comten processor functioning as a

front-end processor. Terminals using start/stop

or

BSC pro-

tocols are supported by the remote concentrator through

the CNS interface modules ASWX

and

BSWX. While these

modules perform the data-link function, the Transparent

Concentrator (TCON) module performs the function

of

multiplexing! demuItiplexing

of

the data from each ter-

minal. The module

that

handles the network's internal

protocol (CNS

Trunk

Handler) is the

TCTH

module. This

internal protocol is transparent

to

the terminals

and

the host

processors. CNS emulator modules, comparable

to

the

Emulation modules above, are resident in the front-end

processor for each terminal-type sending

and

receiving data.

An

optional module,

STAR,

performs

trunk

monitoring

and

reporting. Information

on

trunk

utiIization, current

circuit status,

and

error statistics are provided by

STAR,

along with automatic notification

of

circuit failures. Other

CNS features support alternate routing, node reconfigura-

tion, satellite links, remote auto-dial,

and

multiple-circuit

trunks.

Network

Control Program (NCP)

Both the CNS

and

the Emulation packages require a sepa-

rate subchannel address for each terminal communicating

with the host. Controlling multiple accesses consumes signi-

ficant host processor time.

NCP

provides for all data between

the host and the front-end processor

to

be

multiplexed over

a single subchanneI, significantly reducing the host control

NCP

requires

that

the

method be either

IBM

TCAM

or

support

for multiple

When

the Comten

NCP

system is used

to

emulate in a

mode

comparable

to

IBM's

NCP

Partitioned Emulation Process-

ing

(PEP)

mode, Comten

NCP

is operated concurrently with

Emulation

and

CNS.

This capability is generally needed

to

ease application program conversion from

the

270X multi-

access

mode

to

NCP

single-access mode.

System Generation

Parameter setting for tailoring either Emulation,

CNS,

or

NCP

for a given system

is

done in

CODEL,

a Comten source

language. System generation is performed

on

the

host

com-

puter

and

is loaded into

the

front-end processor,

or

down-

line

to

remote nodes.

Data

Switching

System (OSS)

The Comten processor can

be

operated as a nodal processor

on

a distributed network by the use

of

the

Data

Switching

System. Operated under the control

of

the

Communications

Operating System (COS),

DSS

operates coresident with

NCP

and

CNS.

DSS

adds

to

the

capabilities

of

NCP

file-

level host interface, basic message handling

and

queuing,

message switching, network security,

and

network control

functions.

In

effect,

DSS

can independently drive a com-

munications network.

DSS

is composed

of

four modules: the Communications

Access

Method

(CAM),

the

Data

Switch Message Control

Program

(DS/MCP),

the

Network Manager,

and

the

File

Access

Method

(F

AM).

The

Communications Access

Method

controls

the

access

to

all lines assigned

to

CAM,

whether

to

a terminal,

to

another

node

processor,

or

to

a host processor.

Four

sub-modules

of

CAM

provide a standard interface with the remainder

of

the

CAM

module

and

each

of

the four separate protocols. The

sub-modules are called Transmission Subsystem Elements

(TSE). The Basic

Mode

SNA

TSE

provides

the

interface

between

CAM

and

data

received (from terminals) by the

processor via

NCP.

The

Communications Networking Sys-

tem

TSE

provides

the

interface between

CAM

and

data

received (from terminals

and

other Comten processors) by

the processor via CNS.

The

3270 Emulation

TSE

provides

the

interface between

CAM

and

up

to

four

IBM

360/370

hosts. The hosts, operating BT

AM

or

TCAM

applications

programs, view

the

interface between

CAM

and

IBM

360/

370 systems executing ''read/write'' queries

to

DDS

through

the

host's Basic Sequential Access

Method

(BSAM).

The

Data

Switch/Message Control

Program

performs the

message handling

fu~on

for

data

it receives from

CAM.

Messages are analyzed, edited, routed, queued,

and

logged.

Error

recovery

is

controlled by this

DSS

module.

The Network Manager portion

of

DSS

is

responsible for

network configuration, startup, shutdown, session establish-

ment,

and

other related functions.

The

File Access

Method

module

of

DSS

provides the

access interface between locally attached disk drives, card

readers,

and

printers

and

the

Data

Switch/Message Control

Program.

An

updated version

of

DSS

is presently under development.

Release 2

of

DSS

will he available in 1980,

and

reportedly

will support, in addition

to

all Release 1 functions, user file

access, disk queues, multiple priority for queues, detailed

statistics files,

and

extencied support for any

start/stop

and

BSC devices

of

NCP.

Comten Telecommunications Access

Method

(CTAM)

CTAM

is

a message switching software package originally

written for Comten's 476 Communications Processor

but

since

adapted

to

run

on

the 3690. The package performs

twice as fast

on

the

3690

as

on

the

476.

CT

AM

provides

the

communications control functions

and

interfaces for the different types

of

lines

and

terminal devices.

The software system consists

of

two

modules: the Com-

munications Control Package, which runs

on

the Comten

processor,

and

the

Computer

Interface Package, which runs

in the

IBM

360/370 host.

The

Communications Control

Package provides for stand-alone message switching

and,

when used in conjunction with the Computer Interface

Package, provides

support

as a front end.

The

Communications

Control

Package

(the

Comten

processor-resident portion

of

CT

AM)

controls

the

com-

munications lines

and

terminal devices, validates message

header information, performs line error processing,

and

queues messages.

The

Computer

Interface Package (the host-

resident portion

of

CT

AM)

controls the channel,

and

serves

to

replace

the

IBM

telecommunications access method

(TCAM,

BTAM,

etc.).

Peripherals

Flexible disk storage arrangements are provided including

removable pack

and

fixed head units, as well as

the

capa-

bility

to

support

IBM

3336-style drives from

IBM

and

some

independents.

The 7214 Controller attaches

to

one

position

on

the

Block

Multiplexer channel

and

supports

up

to

nine double-density

2314-style drives;

if

the

full complement

of

nine drives is

installed,

one

is a spare. Two drive models are available; the

6214 single spindle

and

the

6224 dual spindle. Any com-

bination

of

models is supported

that

does

not

exceed nine

spindles.

Each

spindle accepts a 2316 disk pack organized in

two sets

of

200 interleaved cylinders; each spindle is

two

logical units.

The

capacity supported by each spindle is

58.352 megabytes. Average head positioning time is 35 milli-

seconds. Rotational delay averages 12.5 milliseconds. The

transfer rate is 312K bytes per second.

Fixed disk drives

and

3330-11-style removable

pack

drives

can be attached

to

the Block Multiplexer

or

Integrated File

Adapter. Either a T7060

or

a T7065 Storage Control Unit is

required

to

attach

to

a 3640 either via

an

IF

A

or

to

one

position

on

a block multiplexer. The Storage Control Unit

accommodates

up

to

four drives in any combination

of

24-

megabyte (T6124-A1)

or

48-megabyte (T6148-A1) fixed

disk

drives

and

ISO-megabyte (T6215-A1)

or

300-megahyte

(T6230-A1) removable pack drives

that

accept

IBM

3336-11

style disk packs. The

(lXed

disk drives also include 97K bytes

of

storage under fixed heads

(no

head positioning delay).

The

data

transfer rate for all models

is

l,209K bytes

per

second. The rotational delay for all models is 8.4 milli-

seconds. The average head positioning time for

the

fixed

disk models is 40 milliseconds; for

the

removable pack

,~

drives, it is 30 milliseconds.

Communications Processors

MANAGEMENT

SUMMARY

The Comten

3560

II,

3670

II, and

3690

can be viewed

as

a

series

of

communications processor systems with the

higher numbered systems offering greater memory capac-

ity, communications line handling capacity, and direct

host attachment capacity' than lower numbered systems.

Additionally, the Comten

3690

effectively operates three

to

six

times faster than the Comten

3650

II

and

3670

II.

Included

in

the equipment price

is

a

full

complement of

software to operate the processor system

as

either a front-

end processor,

as

a remote concentrator processor, or

as

a

stand-alone communications processor. Both the equip-

ment and the software closely parallel the operation of

IBM's

370X

communications processors.

As

a result,

when using the Comten Emulation or the Comten CNS

software packages

in

a Comten

36XO

that

is

attached to

an IBM 360/370, no modification to the host software

access

method or application programs

is

required. When

using Comten NCP, the host

access

method must

be

VTAM or TCAM, the same requirement imposed

by

IBM's NCP. Comten has enhanced

its

position

as

a

supplier of competitive communications processors inter-

facing with IBM System 360/370 and the IBM plug-

compatible systems,

by

the July announcement of

Data

Switching System (DSS). This

new

software module, in

conjunction with existing software, conforms to the

ground rules of IBM's SNA and affords the Comten

processors the capability to operate as distributed system

nodal processors. DSS

will

support SNA's protocol

(SDLC) and the capabilities SNA described for IBM's

3705

II under the NCP / Advanced Communications

Function.

CONFIGURATION

The Comten

3670

II

and the Comten

3650

II are based

on the same hardwired processor with a memory

cycle

of

650

nanoseconds and a 16-bit word. The

3650

is

a stripped-

down version

of

the

3670

and supports a reduced number

of

direct host connections, communications lines, and memory

capacity.

The Comten

3690

has a microprogrammed processor with

architectural sophistication that enables the

3690

to operate

from three

to

six times faster than the 3650/3670, despite

the fact that

all

three processors have the same memory

cycle

time.

The most notable architectural changes that contribute to

the speed enhancement

of

the

3690

are: the processor logic

of

each

36XO.

Software

to

operate the

36XO's

as front-ends, remote con-

centrators, and as stand-alone communications processors

is

included with the equipment. The Emulation package per-

mits the

36XO

to

function as an IBM 370X

or

as an IBM

370X emulating an IBM 270X.

The Communications Networking System (CNS) package

has all of the capabilities

of

the Emulation package plus

the ability for multiple Comten processors within a network

to

communicate with each other.

The Network Control Program (NCP) relieves the host

processor

of

the bulk

of

network control functions and

is

comparable

to

IBM's NCP. The host access method, when

operating

NCP

in the Comten processor, must be IBM's

TCAM or VTAM.

The Data Switching System (DSS), scheduled for early 1978

release, augments

NCP

and CNS

to

enable the Comten

processor

to

efficiently operate as a distributed network

nodal processor, conforming

to

the rules established by

IBM's System Network Architecture (SNA).

Asynchronous lines

up

to

19.2K bps, and synchronous

lines up

to

S6K

bps are supported in either half- or full-

duplex mode. Major protocols supported including Tele-

type, BSC, CNS trunkline (Comten's internal, BSC-Iike

protocol), and

SDLe.

Comten

3650

II

The 3650 II

is

offered in four basic models. Two

of

the

models are intended for use as a front-end processor and two

of

the models are intended for use as a remote concentrator.

All models include the base cabinet with the 650-nanosecond

processor, 32K bytes

of

memory, the Integral Program Load

Device and two Direct Storage Access channels. The two

front-end processor models, the 3650-C2 and the 3650-D2,

include one IBM Channel Interface Adapter, which provides

a direct storage access connection with the host computer .

system. An optional second channel

is

available for attach-

ment

of

either peripherals requiring a direct channel inter-

face

or

a second IBM Channel Interface Adapter. The latter

can be attached

to

the same host

or

to

another host

computer. The C2 and

D2

models also iriclude a Communi-

cations Interface Module that

will

permit the attachment

of

up

to

eight Modem Interface Modules (MIM)

to

the sytem.

Each Modem Interface Module

will

support up

to

16

com-

munications lines.

The base cabinet

of

the 3650-C2 has space and electrical

interfaces

to

accommodate three Logic Modules.

(A

Logic

Module

is

a deck

of

up

to

70 circuit boards occupying about

23

x 6 x 9 inches

of

space within the cabinet). Three

of

the

four types

of

attachable MIM's require the space

of

one

Logic Module. Three

of

these MIM's, in any combination,

can be installed on the

36SO-C2

models with each

MIM

supporting

up

to

16

lines. A fourth type

of

MIM, the DLC-

MIM, occupies one-half

of

two adjacent Logic Modules.

The basic

36SO-C2

therefore can accommodate only two

of

the DLC-MIM's. Physical considerations prevent the third

Logic Module from being used when two DLC-MIM's are

attached.

An

alternate configuration permits one DLC-

MIM

and one

of

the other three types

of

MIM's

to

be

attached. Expansion cabinets (Module Controllers) must be

employed to add more MIM's to reach the system maximum

of

eight MIM's. The Module Controllers are available in two

models. One model supplies space

to

accommodate six Logic

Modules; the other model supplies space

to

date.\2 Logic Modules. Two additional models, a 6

and

a 12··U\1 size, provide for two

365O's

will

support eight full-duplex communi-

cations lines. The two features are

used

to support Comten's

Comten

3670

II

The Comten

3670

is

offered in

five

basic models. Two

models, the Comten 3670-Hl and

Jl,

are intended as remote

concentrator processolli. The remaining three, the Comten

3670-EI,

Fl,

and

GI,

are intended for use as front-end

processolli.

All

models include the base cabinet with the

650-

nanosecond processor,

64K

bytes

of

memory, an Integral

Program Load Device, two Direct Storage Access Channels,

and one Communications Interface Module (CIM). The

CIM can accommodate up to eight Modem Interface Mod-

ules

(MIM). Each MIM can support

line

Interfaces for up

to

16

communications lines.

The three front-end basic systems (EI,

FI,

GI) include one

IBM Channel Interface Adapter. Up to three additional

adaptelli, along with up

to

eight direct access peripheral

controllelli, can

be

optionally attached. A Block Multi-

plexer feature

is

required

to

attach the peripheral con-

trollers. The Block Multiplexer attaches to the Direct Stor-

age Access Channel. Alternatively, an Intgrated File

Adapter (IF

A)

can be attached to the Direct Storage

Access

Channel, to support up to four disk drives. Two additional

Communiations Interface Modules can be optionally added

to the basic CIM for all models, permitting attachment

of

a

total

of

24

MIM's

or

up to 384 communications lines.

The three front-end base models, the 3670-EI,

FI,

and GI,

have

11,

19,

and

27

Logic Modules, respectively. A Logic

Module

is

the space available to mount one rack

of

PC

boards. When more MIM's are required than can be

contained

in

the base configuration, expansion cabinets

(Module Controllelli) are necessary. Module Controllelli are

available

in

4 models containing

6,

12,

18,

and

24

Logic

Modules. Each controller comes in a single processor velliion

and a dual processor velliion. The dual processor velliion

permits two 3670's to be attached to the controller. The net

effect

is

that two front-end processolli can have aceess

to

the

communications lines that are attached to the controller.

The two remote concentrator systems (HI,

JI)

include one

BSC-MIM with one trunk line interface that accommodates

up to 8 full-duplex lines

at

speeds up

to

56K

bps. One

additional Communications Interface Module can be op-

tionally added, permitting a total

of

24 MIM's

or

up

to

384

communications lines, Two Direct Storage Access Channels

are available

on

the remote

System

for attachment

of

up

to

16

direct access peripheral cootrollelli when a Block Multi-

plexer

is

attached to each Direct Storage Access Channel.

The basic 3670-Hl has

12

Logic Modules. When adding

IDOre

MIM's than can

be

contained

in

the base configura-

tion, the Module Controllelli, as described ahove, are used.

Comten

3690

The Comten 3690

is

offered in

five

basic models. All models

include the 520-nanosecond, microprogrammed processor

with dual-odd/even storage access, an Integral Program

Load Device,

256K

bytes

of

650-nanosecond memory, and

one Communications Adapter (CA). The CA accommo-

dates up to 8 Modem Interface Modules and associated Line

Interfaces

to

support up to

128

communications lines.

Up

to

three additional CA's can be optionally attached permitting

physically attaching up to

512

communications lines per

3690 system. Since the basic models include space for one,

two, or six Logic Modules, Module Controller expansion

cabinets are provided to accommodate the attachment

of

MIM's and Line Interfaces. The Module Controllelli are

available to handle Logic Module requirements

of

6,

12, 18,

24,

30

or

36

Logic Modules. Each

of

the controller sizes

has a velliion that permits dual 3690's to access the con-

troller and the lines attached to that controller.

The basic

256K

bytes

of

memory can

be

expanded to

1024K

bytes

by

the attachment

of

up to six Memory Modules;

each module contains

128K

bytes

of

memory.

The

five

3690 basic models differ

in

the number

of

Direct

Storage

Access

Channels (DSAC) provided and the device

that can be attached to the DSAC's.

The 3690-Al

is

intended to operate

as

a stand-alone data

switching system configurated to support a variety

of

periph-

eral attachments. Therefore, the 3690-Al provides four

DSACs with one

of

the DSACs having a Block Multiplexer

Channel attached. The Block Multiplexer has the capacity

to accommodate up to eight peripheral controllelli. The

remaining three DSAC's can optionally receive Block Multi-

DDS

interfaces are supported in either

full- or half-duplex mode. Notable among the protocols.

supported are binary synchronous communication (BSC).

SDLC, and CNS trunkline. The latter is a BSC-like protocol

used internally on Comten networks.

Each type

of

line interface requires specific Modem Interface

Module and Une Interface features. These features are

attached to the system Communications Interface Module.

SOFTWARE

Currently. three major software packages are available.

at no additional charge. for operating Comten

36XO

sys-

tems. They are Comten Emulation. Communications

Net-

working System (CNS), and Network Control Program

(NCP).

Emulation

Comten Emulation permits the

36XO

to operate as an

IBM

3704/3705 controller. including the capability to emulate an

IBM 270X. In addition to permitting one ('omten

36XO

to

replace multiple 270X/370X devices attached to one host.

the

36XO

can be connected to multiple hosts. Emulation

also supports terminals that are not compatible with the

270X

and 370X.

Emulation consists

of

a module for each terminal-type

requiring support and a string

of

special purpose programs

such as TlLS, ABRD. MAF. and

DIAL

Tn.s.

channel address that

is

associated with a particular applica-

tion. The assignment

is

based upon the terminal operator's

description

of

the linkage required. TILS includes a feature

that

will

automatically reroute transactions

to

a backup host

when the primary host

is

unavailable. ABRD, Automatic

Baud Rate Detection, enables mUltiple start/stop terminals

with different speeds and data-link control procedures to

share the same line to a Comten front-end processor. ABRD

is used

in

conjunction with TILS. When a terminal operator

initiates a linkage under TILS, it

is

ABRD that determines

the terminal's speed and data-link control. SILS, Site-Ini-

tiated Line Switching, under the control

of

the front-end

processor's operator, performs the TILS function for dedi-

cated lines. MAF, Multiple Access Facility, relieves the host

of

the polling function for IBM 3270 systems and permits the

terminals to select applications

in

any host computer attached

to

the Comten front-end processor. DIAL, Automatic Dial-

ing, handles up

to

16

phone lines for host-originated calls.

Emulation also provides utility programs for monitoring

and maintenance, on-line terminal testing, console

I/O,

and

on-line system generation.

Communications

Network

System (CNS)

When there

is

a need for two

or

more Comten processors

to

communicate with each other, within a network, the

Emulation software package

is

replaced with the Communi-

cations Networking System (CNS). While performing all

of

the functions

of

Emulation, CNS also enables a Comten

processor functioning as a remote concentrator

to

transmit

to

and receive from a Comten processor functioning as a

front-end processor. Terminals using start/stop

or

BSC

protocols are supported by the remote concentrator through

the CNS interface modules ASWX and BSWX. While these

modules perform the data-link function, the Transparent

Concentrator (TCON) module performs the function

of

multiplexing/demultiplexing

of

the data from each terminal.

The module that handles the network's internal protocol

(CNS Trunk Handler)

is

the TCTH module. This internal

protocol

is

transparent

to

the terminals and the host pro-

cessors. CNS emuhltor modules, comparable to the Emula-

tion modules above, are resident

in

the front-end processor

for each terminal-type sending and receiving data. An

optional module, STAR, performs trunk monitoring and

reporting. Information on trunk utilization, current circuit

status, and error statistics are provided

by

STAR, along with

automatic notification

of

circuit failures. Other CNS features

support alternate routing, node reconfiguration, satellite

links, remote auto-dial, and multiple-circuit trunks.

Network

Control Program (NCP)

Both the CNS and the Emulation packages require a

separate subcharmel address for each terminal communicat-

ing with the host. Controlling multiple accesses consumes

significant host processor time.

NCP

provides for all data

between the host and the front-end processor to be multi-

plexed over a single subchannel, significantly reducing the

host control function. Comten

NCP

is compatible with IBM

NCP

in performing the line handling and communicaitons

control functions. While the access method in the host

is

transparent

to

Emulation and CNS,

NCP

requires that the

host access method be either IBM TCAM or VTAM.

Comten

NCP

provides concurrent support for multiple IBM.

host processors.

When the Comten

NCP

system

is

used to emulate in a mode

comparable

to

IBM's

NCP

Partitioned Emulation Process-

ing (PEP) mode, Comten

NCP

is

operated concurrently

with

Emul~tion

and CNS. This capability

is

generally

needed

to

ease application program conversion from the

270X multi-access mode

to

NCP

single-access mode.

System Generation

Parameter setting for tailoring either Emulation, CNS, or

NCP

for a given system is done in CODEL, a Comten

source language. System generation

is

performed on the host

computer and

is

loaded into the front-end processor.

Data

Switching

System (OSS)

The Comten processor can be operated as a nodal processor

on a distributed network by the use

of

the Data Switching

System. Operated under the control

of

the Communications

Operating System (COS),

DSS

operates coresident with

NCP

and CNS.

DSS

adds to the capabilities

of

NCP

file-

level

host interface, basic message handling and queuing,

message switching, network security, and network control

functions.

In

effect, DSS can independently drive a com-

munications network.

DSS

is

composed

of

four modules: the Communications

Access Method (CAM), the Data Switch Message Control

Program

(DS/MCP),

the Network Manager, and the File

Access Method (F AM).

The Communications Access Method t:ontrols the access

to

all lines assigned

to

CAM, whether

to

a terminal,

to

another

node processor,

or

to

a host processor. Four sub-modules

of

CAM

provide a standard interface with the remainder

of

the CAM module and each

of

the four separate protocols.

The sub-modules are called Transmission Subsytem Ele-

ments (TSE). The Basic Mode SNA TSE provides the

interface between CAM and data received (from terminals)

by the processor via NCP. The Communications Network-

ing System TSE provides the interface between

CAM

and

data received (from terminals

and

other Comten processors)

by the processor via CNS. The 3270 Emulation TSE

provides the interface between CAM and up

to

four IBM

360/370 hosts. The hosts, operating BTAM

or

TCAM

applications programs,

view

the interface between CAM and

IBM 360/370 systems executing "read/write" queries

to

DDS

through the host's Basic Sequential Access Method

(BSAM).

The Data Switch/Message Control Program performs the

message handling function for data it receives from CAM.

Messages are analyzed, edited, routed, queued, and logged.

Error recovery

is

controlled by this

DSS

module.

The Network Manager portion

of

DSS

is

responsible for

network configuration, startup, shutdown, session estab-

lishment, and other related functions.

The File Access Method module

of

DSS

provides the access

interface between locally attached disk drives, card readers,

and printers and the Data Switch/Message Control Pro-

gram.

Application programs

in

the Comten processor have inter-

faces with the File Access Method, the

Data

Switch/

Message Control Program, and the Network Manager

through a module

of

the operating system (COS) called

Application Program Support.

C13-242-201

Processors

Comten

476

Communications Processor

MANAGEMENT

SUMMARY

The Comten

476

Communications Processor

is

the

predecessor

of

the Comten 3650/3670/3690 family

of

communications processors and the successor to the

Comten

45

and

65,

which were themselves replacements

for the Comten

40

and

60.

Until the mid-1977 introduction of the Comten

3690

with

DSS software and a full line of

36XO

peripherals, the

Comten

476

represented Comten's only offering of a free-

standing data communications processor. The Comten

476

is

upward compatible with the faster Comten

3690

system.

While still actively marketed and suitable for certain

requirements, the Comten

476

increasingly becomes

less

attractive on a price/performance basis compared

to the Comten

36XO

processors. This

is

CONFIGURATION

The Comten Base Processing System consists

of

a central

processing unit,

32K

bytes of 750-nanosecond, 32-bit word

core storage, integral load device

with

programmable read-

only storage, and real-time clock.

The base system has four channels for attaching any com-

bination of four Computer Interface Adapters, Peripheral

Interface Adapters or directly attached peripheral sub-

systems.

Up

to

112

communication channels can be attached

to the base system

via

seven Modem Interface Modules

(MIM's). The

seven

MIM's attach to the base system

Communication Interface Module (CIM). A second CIM

can be added for attaching

128

more communication

lines

via

eight

MIM's. Three model upgrades are available, each

adding an expansion cabinet and eight additional

logic

module spaces to a maximum

of

4 cabinets and twenty-

eight

logic

modules. Memory is expandable from a

basic

32K

bytes to

512K

bytes

in

32K

byte increments.

The Comten

476

is

available in four models that differ

only in the number of Logic Modules they contain. A Logic

Module

is

equivalent to the space and electrical connec-

tions required to mount one rack

of

PC boards. Mounting

requirements of attachments are expressed in Logic Modules.

The Comten 476-Al contains space for 4 Logic Modules;

the

A2

model, for

12

Logic

Modules; the

A3

model, for

20

Logic

Modules; and the

A4

model, for

28

Logic Modules

TRANSMISSION SPECIFICATIONS

The accompanying table, Communications Lines Handled,

summarizes

the

capabilities

of

the

system for accommo-

SOFTWARE

All Comten system are supplied with full software support

including operating systems, assembler, a teleeommunica-

tions access package, a network control package,

and

a series

of

utility programs for monitoring

and

control.

The Comten operating system is built around

an

exeeutive

supervisor program which controls all computer

and

I/O

tasks. Supervisor

functions

include

concurrent,

multi-

sequential task scheduling by priority, program exeeution

on

a variable time basis via a real time clock, peripheral

aDocation

and

Defmition Language (CODEL) which is translated into

machine language by the assembler processor.

The

Comten Teleeommunication Access Method (CTAM)

pro'rides the communication control functions

and

inter-

faces

to

the different types

of

lines and terminal de'rices.

CTAM

consists

of

two packages: the Network Control

Package

(NCP)

for the Comten processor

and

the

Compute

Interface Package (CIP) for the

IBM

360/370.

NCP

pro-

vides stand alone message switching and, when used in

conjunction with CIP, provides front-end capabilities.

The

Network Control Package (NCP), the 476 resident

portion

of

CT

AM,

controls the communication lines and

terminal de'rices, validates message header information,

performs line error processing

and

queues messages. The

Computer Interface Package

(OP),

the

host computer

resident portion

of

CTAM,

controls the channel

and

replaces

the

IBM

access method (TCAM,

BTAM,

etc.).

The utility packages offered by Comten include a comple-

ment

of

monitoring functions. Subchannel, communica-

tions line,

and

trunk

subline utilization information is

pro'rided. Input controls

to

effect changes in these func-

tions are also offered.

PRICING

MANAGEMENT

SUMMARY

Comten, Inc. is among the largest

of

the

independents in

the data communications field

and

offers a variety

of

programmable communications processors designed for

message switching and front-end processing.

Comten

introduced

its first processors,

the

Model 45

and

65,

in

1969 followed in 1971

by

the

Model 20. The Model

45

and

65

were designed primarily for front-end

processing and message switching applications while

the

Model 20 was designed for

remote

concentration. In

September 1975,

the

company

announced

its Model 476,

which effectively replaced Models 20, 45,

and

65. Since

the

introduction

of

the 476, the

latter

models have

been

dropped from

the

product

line.

In

order

to

successfully compete

with

the

IBM

270X

and

370X

product

lines Comten

introduced

two

processors

that

provide emulation

of

the

IBM

products,

as

well as

providing custom applications in front-end, message

Switching,

and

other communications processing. The first

of

these products, the Model 3670, was

introduced

by

I>

A family

of

programmable processors

for

front-end, message-switching,

and

communi-

cation control applications, including

IBM

270X

and

370X emulation.

Memory sizes range from

32K

to

512K bytes

and

support

from 128

to

384 communications

lines.

Options include

up

to

4 channel

input

and

an

extensive variety

of

line set combinations with

line transmission rates

from

75 bps

to

230K

bps as well as asynchronous

and

synchronous

transmission

in

both

half- and full-duplex

modes.

A Model 476 in a basic configuration with

32K memory

that

supports

64 communica-

tion lines rents

for

approximately $4,600

on

the tilll:e-year lease plan, including main-

tenance.

The

monthly

rental

for

a Model 3670 with

256K

of

memory

that

supports

128 com-

munication lines

is

approximately $7,430,

including maintenance.

Comten in 1972. In March 1975, a smaller version

of

the

3670, the Model 3650, was introduced.

Following IBM's lead, Comten introduced enhanced

versions

of

the 3650 and 3670 in February 1976.

Appropriately named the Model 3650-II and

3670-11

(the

older models became 3650-1 and 3670-1), the systems

offered enhancements over their predecessors, such

as

semiconductor storage and increased line capacity.

The accompanying chart

of

system characteristics

highlights features

of

each

of

the Com ten systems and

allows comparison between models.

Compared

to

the

IBM

3705, the Comten 3650 and 3670

offer a number

of

distinct advantages. The most

significant is lower cost. Rental prices for the

IBM

3705

range from $1,250

to

$16,000 per month, while the

equivalent Comten systems range from $1,000

to

$8,000

per month, representing a considerable cost savings. In

addition to this cost savings, other advantages

of

the

Comten system are faster memory cycle time (650

nanoseconds compared

to

1000 nanoseconds for the

IBM

3705), greater maximum line capacity (384 versus 356 for

the

IBM

370X), and greater memory capacity (512K

bytes versus 256K for the

IBM

3705). Types

of

communication lines handled by the Comten systems are

comparable

to

IBM

and are shown in Table I and II.

can

be

added for attaching 128 more

communication lines via eight MIM's. Three model upgrades

are available, each adding an expansion cabinet and eight

additional logic module spaces to a maximum

of

All

respondents were using their Comten units with

IBM

host computers. The host systems ranged from one

System 360/30 to four System 370/168 computers.

Applications varied,

but

were predominately

IBM

270X

and 370X emulation. Other applications included

communications control, front-end processing, data

concentration, and

message

switching.

As

reflected by the ratings, users were generally quite

satisfied with their Comten units. The most often cited

advantage

was

cost savings relative to the

IBM

3705. A

number

of

users also cited favorable flexibility, reliability,

and increased throughput

of

the Comten units. Other

advantages listed included the capability for interfacing

with 4 CPU's, greater line capacity, expansion and growth

potential, and faster processing speeds than

IBM

systems.

On the negative side, criticisms were few,

but

did include

individual comments from users such

as

a poorly written

assembly package and a

phYSically

large unit. Two users

reported faulty power supplies,

but

both

indicated these

problems had been solved by Comten. 0

SOFTWARE

All

Com ten system are supplied with full software support

including operating systems, assembler, a telecommunica-

tions access package, a network control package, emulation

of

the

IBM

270X and 370X, and a series

of

utility programs

for monitoring and control.

The Comten operating system

is

built around an executive

supervisor program which controls all computer and I/O

tasks. Supervisor functions include concurrent, multi-

sequential task scheduling by priority, program execution

on a variable time basis via a real time clock, peripheral

allocation and I/O control communication, I/O initiation

and coordination, interrupt tabling, and console control.

The assembler for the Comten system

is

very simlar

to

the

IBM

360/370 assembler. Comten uses the Communication

Definition Language

(CO

DEL) which

is

translated into

machine language by the assembler processor.

The Network Control Package (NCP), the resident portion

of

CTAM, controls the communication lines and terminal

devices, Validates message header information, line error

processing and queuing messages.

It

also provides a

compatible interface to

IBM

TCAM

and

VTAM

(3650 and

3670 only). The emulation can also be used with the

Partitioned Emulation Processing (PEP) software system.

The Comten Network System (CNS) provides the system

software and procedures

to

connect Comten processors to

front-end processors, processors

to

remote concentrators,

and remote concentrators

to

remote concentrators in both

emulation and

NCP

modes.

The utility packages offered by Com ten include a

complement

of

monitoring functions. Subchannel, com-

munications line, and trunk subline utilization information

is

provided. Input controls

to

effect changes in these

functions are also offered.

PRICING

/

I

"'-.

The Comten Telecommunication Access Method

(crAM)

provides the communication control functions and

interfaces to the different types

of

lines and terminal

devices.

CTAM

consists

of

two packages: the Network

Control Package (NCP) for the Com ten processor and the

Compute Interface Package (CIP) for the

IBM

360/370-

NCP

provides stand alone message switching and, when

used in conjunction with CIP, provides front-end

capabilities.

The Comten processors are available for purchase or

on

,/

lease. In the case

of

the 476 and related features, lease '

terms are 3 and 5 years. For the 3650 and 3670, the length "'-

of

lease

is

monthly and 2 years. In the following list, lease

prices are

given

and combined where appropriate_ These

leases include monthly maintenance. A separate main-

tenance contract is available for purchased units.
