CHAPTER 1 - OPERATION  
The Patton 3040/V35 (CTS MD-V.35/TCB) is a network enhancement accessory intended for  
high speed synchronous or asynchronous V.35 modem, DSU/CSU, or port sharing  
applications. The 3040/V35 (CTS MD-V.35/TCB) allows for immediate expansion of a  
system without the requirement of additional communication lines. The 3040/V35 (CTS MD-  
V.35/TCB) allows any combination of up to four V.35 DCE or DTE devices to share a single  
V.35 DCE or DTE high speed link in a point-to-point or multi-point polled network.  
Channel Clocking  
The 3040/V35 (CTS MD-V.35/TCB) is protocol transparent and operates in synchronous and  
asynchronous environments at data rates up to 2.048Mbps, depending on cable length and  
attached equipment. Clocking can be derived from the Master Port clock, (pins Y,AA for TT or  
U,W for ETT and V,X for RT), the internal clock generator or any Sub-Channel clock, (pins  
Y,AA for TT or U,W for ETT and V,X for RT).  
Fallback Clocking  
In the event of loss of an externally provided clock or optionally Sub-Channel 1 DCD becoming  
inactive, the 3040/V35 (CTS MD-V.35/TCB) has the ability to automatically fall back to the  
predetermined internal baud rate clock or the Sub-Channel 4 RX Clock (pins V,X).  
Channel Interface  
The 3040/V35 (CTS MD-V.35/TCB) has five V.35 (MR-34) female connectors located on the  
rear of the unit. Also a DB-25 connector is provided in parallel with the Master Port V.35  
connector. Each port is DCE/DTE selectable, which eliminates the need for crossover cables.  
DSR or DTR can additionally be forced to the active state individually on each Sub-Channel by  
Jumpercontrol.

Anti-streaming  
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. The 3040/V35 (CTS MD-V.35/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 3040/V35 (CTS MD-V.35/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. The Sub-Channel will no longer receive data or CTS from the Master Port.  
Any data sent to the Master Port by the streaming device will be lost. Once a Sub-Channel is  
locked out due to streaming, the Sub-Channel will remain locked out until the attached device  
removes the streaming condition. If RTS is held active, RTS must become inactive, if  
continuous data transitions have triggered the Anti-Stream logic, the transitions must stop  
before the 3040/V35 (CTS MD-V.35/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-Streaming - If manual Anti-Stream protection is chosen, a streaming condition  
caused by one of the attached terminals can be quickly corrected by the 3040/V35 (CTS MD-  
V.35/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 re-establish 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 3040/V35 (CTS MD-V.35/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.  
OPERATION

3040/V35  
INSTALLATION AND OPERATIONS MANUAL  
139001UA  
In the Scanning Mode the CTS 3040/V35 (CTS MD-V.35/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 Sub-Channel is switched through to  
the master port by the 3040/V35 (CTS MD-V.35/TCB). All remaining Sub-Channels are  
locked out until the first device becomes inactive. When the Sub-Channel device becomes  
inactive, the 3040/V35 (CTS MD-V.35/TCB) will resume scanning the Sub-Channels for  
anotheractivesignal.  
When configured for Priority Mode operation, the 3040/V35 (CTS MD-V.35/TCB) monitors all  
Sub-Channels simultaneously with Sub-Channel 1 having the highest priority. When a Sub-  
Channel becomes inactive, the 3040/V35 (CTS MD-V.35/TCB) will automatically default to the  
highestpriority(lowestnumber)Sub-Channelwithactivity.  
Contention for the Master port is accomplished by asserting RTS (Request to Send) if the  
Sub-Port is configured as a DCE, DCD (Data Carrier Detect) 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, RTS or DCD, as well as selection of contention mode, “Data Transitions”  
or “Interface Lead” activation, can be selected on an individual basis for each Sub-Channel.  
Once a Sub-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 RTS. The CTS returned to the Master will have an optional delay  
added before the signal is returned to the Sub-Channel port.  
Port Enable / Disable, front panel switches must be pushed in (GREEN indication) for a Sub-  
Channel to access the Master Port regardless of the mode of operation selected.  
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 to ASYNC.

Interface Connections  
All connections are made via industry standard CCITT V.35 (MR-34) female connectors  
located on the rear of the unit. The Following interface leads are implemented, Chassis (A),  
TD (P,S), RD (R,T), RTS (C), CTS (D), DSR (E), Sig Gnd(B), DCD (F), TT (Y,AA), RT (V,X),  
DTR(H),ETT(U,W).  
In addition the master port can be accessed via an DB-25 with the following pinout, Chassis  
(1), TD (24,11), RD (23,22), RTS (4), CTS (5), DSR (6), Sig Gnd(7), DCD (8), TT (14,1), RT  
(16,3), DTR (20), ETT (15,2).  
Front Panel LEDs  
Front panel LEDs are provided to indicate power is applied, RD and TD activity from the  
Master Port, Sub-Channel activity of each individual Port, Anti-Stream condition of each Sub-  
Channel and an indication of clock Fallback condition.  
Channel Enable / Disable Switches  
Front panel switches allow operator intervention to remove an individual Sub-Channel from  
accessing the Master Port. Positive latching type switches are provided for each Sub-  
Channel port for isolating or removing a streaming terminal. The Sub-Channel is activated by  
pushing the switch until it is in the “IN” position. The switch will indicate GREEN in color. To  
disable a Sub-Channel push the switch until it locks in the “OUT” position, the switch will  
indicate BLACK in color. Disabling a Sub-Channel with the front panel does not prevent the  
Sub-Channel from receiving data from the Master Port only from sending data to the Master  
Port.  
Power Supply  
A linear power supply is located internally, an external 110/220VAC switch is located on the  
rear of the unit. If chassis ground and signal ground need to be tied together this can also be  
accomplished by switch selection. The unit is Rackmountable for 19" cabinets or optional 23"  
cabinets, by using the provided Rackmount Kit. Safety approvals granted are UL and CSA as  
well as emission approval for FCC Class A.

Tail Circuit Buffers (SW16-4)  
The 3040/V35 (CTS MD-V.35/TCB) has a Tail Circuit Buffer that is automatically selected  
when a Sub-Channel is set as a DTE. The buffer will provide clock synchronization of the data  
from the Sub-Channel to the Master Port for Tail Circuit operations. The buffer is de-activated  
when the Sub-Channel is configured as a DCE. When operating in an asynchronous  
environment the Buffer must be bypassed. To bypass the buffer in a synchronous or  
asynchronous application, set switch SW16-4 to OFF (ASYNC). For normal operation in a  
synchronous environment set SW16-4 to ON (SYNC). When using a tail circuit modem with  
the 3040/V35 (CTS MD-V.35/TCB), the modem connected to the Sub-Channel, should be set  
to External Transmit Clocking. The modem at the remote end of the connection should be set  
to RX-TX Clocking or Slaved TX Clock. This will insure the same clock is present throughout  
the network and clock slippage will not occur.  
Port DCE/DTE Selection (SW5 thru SW14)  
Slide switches SW5 through SW14 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 both  
switches to the DTE position toward the interface connector. If connecting a terminal (DTE) to  
the Sub-Channel, the port should be configured as a DCE. Slide both switched to the DCE  
position away from the interface connector. The port is always configured opposite to the  
interface that is to be connected to it.

DTR / DSR Forced Active (JP8 thru JP12)  
DTR is tied to DSR on each of the Sub-Channel ports. If the device connected does not  
supply a DTR but requires DSR (DTE) or does not supply DSR but requires DTR (DCE),  
installing the forced DTR/DSR jumper (JP8-JP12) for the appropriate Sub-Channel will solve  
this problem. The line is forced to +8V via an 820W resistor, providing isolation to any driver  
that might be on the interface.
