CHAPTER 1 - OPERATION

The 3060/X21 (CTS MD-X.21/TCB) is a network enhancement accessory intended for high
speed Synchronous or Asynchronous X.21 Modem, or port sharing applications. The 3060/
X21 (CTS MD-X.21/TCB) allows for immediate expansion of a system without the requirement
of additional communication lines. The 3060/X21 (CTS MD-X.21/TCB) allows up to six X.21
DCE or DTE devices to share a single X.21 DCE or DTE high speed link in a point-to-point or
multi-point polled network.

Clocking

The Patton 3060/X21 (CTS MD-X.21/TCB) is protocol transparent and operates in
synchronous and asynchronous environments at data rates up to 2048Kbps. Clocking can be
derived from the master port clock (pins 6 &13), the internal clock generator or any Sub­Channel clock (pins 6 &13).

Fallback Clocking

In the event of loss of an externally provided clock the device has the ability to fall back to the
predetermined internal baud rate clock or to the clock provided on Sub-Channel 6.

Channel Interface

The 3060/X21 (CTS MD-X.21/TCB) has seven DB-15 female connectors located on the rear
of the unit. Each port is DCE/DTE selectable, which eliminates the need for a crossover
cable. The Control/Indicate output leads can be individually selected to follow the Modem or
be forced active. The Sub-Channel 6 Control/Indicate input lead can be forced Active or
allowed to follow the interface lead.

Anti-streaming

PATTON ELECTRONICS CO.INSTALLATION AND OPERATIONS MANUAL

3060/X21

A typical problem often encountered is a

“STREAMING”

remote terminal. The streaming
problem can tie up an entire circuit until the offending device has recovered or is powered
down. A streaming condition occurs when a Sub-Channel remains active, disrupting the
polling sequence. The3060/X21 (CTS MD-X.21/TCB) provides two user selectable modes of
controlling a streaming condition, an automatic anti-streaming Abort Timer with eight
selectable block lengths and a setting to disable anti-streaming for large data block transfers,
and a manual Operator Control mode (front panel push button switch).

Automatic Anti-Streaming

- Automatic Anti-streaming will block the asserted control signal
from the Sub-Channel Port, releasing the 3060/X21 (CTS MD-X.21/TCB) to accept requests
from any other Sub-Channel that has not been locked out due to a streaming condition. When
a Sub-Channel is locked out for streaming, a visual indication, by Sub-Channel, is provided on
the front panel.

Port. Any data sent to the Master Port by the streaming device will be lost

The Sub-Channel will no longer receive data or Indicate(I) from the Master

. Once a Sub­Channel is locked out due to streaming, the Sub-Channel will remain locked out until the
attached device removes the streaming condition. If Indicate (I)

DCE)

is held active, I/C lead must become inactive, if continuous data transitions have

(for DTE)

or Control (C)

(for

triggered the Anti-Stream logic, the transitions must stop before the 3060/X21 (CTS MD-X.21/
TCB) will clear the Anti-Stream logic to that Sub-Channel. Removing the Sub-Channel via the
front panel disable switch will not clear the Anti-stream logic for a Sub-Channel once it has
been activated.

Manual Anti-Stream

- A streaming condition caused by one of the attached terminals can be
quickly corrected by the 3060/X21 (CTS MD-X.21/TCB) via the associated front panel locking
switches. A switch is provided for each Sub-Channel and permits the rapid removal of a
streaming terminal without having to disconnect any cables or power down the offending
terminal. Terminals may be selectively removed for self-test and maintenance without affecting
the remaining Sub-Channels. Once the streaming condition has been corrected, the front
panel switch is simply depressed to the locked (Enable) position (Green indicator ON) to
reestablish normal operation. Removing a Sub-Channel with the front panel switch will block
data from the Sub-Channel going to the Master Port but will not block data going from the
Master Port to the Sub-Channel as the Automatic Anti-Stream option did.

Channel Selection Modes

The Patton 3060/X21 (CTS MD-X.21/TCB) provides two selectable sub-channel service
modes of operation, the Scanning Mode and Priority Mode. Depending on system
requirements, either mode may be selected by internal dip switch settings. Both modes switch
on activity from the sub-channel. Activity is defined as raising Control on a sub-channel
configured as a DCE, raising Indicate on a sub-channel configured as a DTE or data
transitions while in the switch on data mode.

Scanning Mode

- In the Scanning Mode the Patton 3060/X21 (CTS MD-X.21/TCB) scans

each Sub-Channel, in sequence, beginning with Sub-Channel 1. This rotational sequence is
repeated continually with each attached Sub-Channel having equal access to the
communications link. When data or control lines from a sub-channel become active that Sub­Channel is switched through to the master port by the 3060/X21 (CTS MD-X.21/TCB). All
remaining Sub-Channels are locked out until the first device becomes inactive. When the Sub­Channel device becomes inactive, the 3060/X21 (CTS MD-X.21/TCB) will resume scanning
the sub-channels for another active signal.

Priority Mode

- When configured for Priority Mode operation, the Patton 3060/X21 (CTS MD-

X.21/TCB) monitors all Sub-Channels simultaneously with Sub-Channel 1 having the highest
priority. When a sub-channel becomes inactive, the 3060/X21 (CTS MD-X.21/TCB) will
automatically default to the highest priority (lowest number) Sub-Channel with activity.

Contention - Contention for the Master port is accomplished by asserting C (Control) if the
Sub-Port is configured as a DCE, I (Indicate) if the Sub-Port is configured as a DTE or Data
Transitions from the attached Sub-Channel devices in either configuration. The active
interface lead, C or I, as well as selection of contention mode,

Lead”

activation, can be selected on an individual basis for each Sub-Channel. Once a Sub-

“Data Transitions”

or

“Interface

Channel asserts an active control signal the control signal will be passed through to the Master
Port, depending on DTE / DCE configuration of the Sub-Channel and Master Port. This
control will be passed without delays. If the Master Port is configured as a DTE the signal will
be passed as C. The I returned from the Master will have an optional delay added before the
signal is returned to the Sub-Channel port.

Channel Tail Circuits

A buffer is built into the unit for tail circuit (DCE to DCE) applications. An 8 bit centered ring
buffer is used to correct the clock phasing errors generated between the Modem on the
Master Port and the Sub-Channel port for the data transferred from the Sub-Channel to the
Master Port. If the unit is operated in an asynchronous environment the buffer must be
bypassed. This is accomplished by moving the SYNC/ASYNC switch.

3060/X21

Interface Connections

All connections are made via industry standard DB-15 (V.11) female connectors located on
the rear of the unit. The following interface leads are implemented: T(2,9), R(4,11), C(3,10),
I(5,12), S(6,13), B(7,14), Gnd (8), Chassis(1).

Front Panel Indicators

The front panel LED indicators associated with each sub-channel identify the active port. A
green POWER ON LED indicates when AC voltage is applied. Two adjacent green LED
indicators illuminate in union with individual port activity and identify Transmit Data (T) and
Receive Data (R) activity. When in Fallback Mode the Fallback LED will illuminate.

Channel Enable / Disable Switches

Positive latching type switches are provided for each DTE port for isolating or removing a
streaming terminal. When activated the switch will indicate GREEN in color. To disable a
sub-channel push the switch inward, the switch will indicate BLACK in color. The port Enable /
Disable, front panel switches must be pushed in (GREEN) for a sub-channel to access the
main channel. Data will be sent from the master to the ports regardless of the Enable /
Disable switch setting, only data from the ports to the master is affected.

Power Supply

A linear power supply is located internally, an external 110/220VA switch is located on the rear
of the unit. If chassis ground and signal ground need to be tied together, this can be
accomplished by switch selection. The unit is Rackmountable for 19” cabinets or optional 23”
cabinets, by using the provided Rack Mount Kit. Safety approvals granted are UL, CSA and
TÜV, as well as emmision approval for FCC Class A and VFG-243.

interface control lead. Set SW27-1 to
position 1 to

ONON

ON if “Switch on Interface Control Lead” is desired. Position 2 through 6 are

ONON

OFFOFF

OFF if sub-channel 1 “Switch on Data” is required. Set

OFFOFF

associated with sub-channels 2 through 6.

Port DCE/DTE Selection (SW7 through SW20)

Slide switches SW7 through SW20 are used to configure DTE/DCE for each port. Slide
Both switches associated with a port to the same position. EXAMPLE: If connecting a

MODEM (DCE Device) to the PORT, then the port should be configured as a DTE
interface. Slide switches SW7 & SW8 to the DTE position (toward the DB-15 connectors).

Factory Test Jumpers (JP1,JP2)

The two test jumpers JP1 and JP2, must be installed for the unit to properly function.
These jumpers are used in the manufacture and test of the product prior to shipment.
