INTERFERENCEINTERFERENCE
INTERFERENCE
The Patton MSDs generate and use radio frequency energy, and if not installed and used
properlythat is, in strict accordance with the manufacturers instructionsmay cause
interference to radio and television reception. The Patton MSDs have been tested and
found to comply with the limits for Class A computing devices in accordance with the
specifications in Subpart J of Part 15 of FCC rules, which are designed to provide reason-
able protection from such interference in a commercial installation. However, there is no
guarantee that interference will not occur in a particular installation. If the Patton MSDs
do cause interference to radio or television reception, which can be determined by
disconnecting the cables, the user is encouraged to try to correct the interference by one
or more of the following measures: moving the computing equipment away from the
receiver, re-orienting the receiving antenna, and/or plugging the receiving equipment
into a different AC outlet (such that the computing equipment and receiver are on
different branches).

The 3028 Turbo (CTS 3028 Turbo (CTS 2031 Turbo)) Statistical Multiplexer has two
primary applications: Point-to-Point and DCX networking (Figure 1-1). Point-to-
Point operations in a single link environment supports up to eight terminals. All
of the DCX networking applications, including direct connections to a DCX 840 or
DCX 850 are supported. The 3028 Turbo (CTS 3028 Turbo (CTS 2031 Turbo)) also
supports the onward linking facilities through a DCX 825/871.
The SDLC/HDLC protocol is a standard feature that supports the bit-oriented
synchronous protocols.

2031 Turbo Statistical Multiplexer
154001UA1-2
The multiplexer combines data traffic from up to eight sources into a high-speed
composite link. Channel speeds supported are from 75bps to 19,200bps with an
automatic channel speed detection (AUTOBAUD) option up to 9,600bps. The
buffer management allows storage of 16K bytes to be shared on demand by the
channels. Each channel is assigned a minimum of 372 bytes of buffer space to
prevent lockout. Because of the buffering action of the 2031, the data rates on the
channel side of the multiplexer may total several times the actual link rate without
data loss. The multiplexer will handle an aggregate of 76,800 bps in constant full-
duplex traffic (with flow control) and a 64,000K bps link without loss of data.
The multiplexer can transmit control messages end-to-end to handle such things
as break propagation, EIA signal propagation, and autobaud speeds. The control
messages are transparent to the user. In addition, any of the EIA interface outputs
can be forced high or low through the user interface.
Multiplexer configuration and operation monitoring is accomplished in a variety
of ways. An ASCII asynchronous terminal can be attached to the supervisory port
on the back panel or to a data channel that has the supervisory access enabled, or
the front panel push-buttons and LCD display can be used. Another method of
access is from a remote multiplexer in a point-to-point or a DCX network applica-
tion. Access to the supervisory function can be password protected for security.
All parameters are contained in nonvolatile storage.
The 3028 Turbo (CTS 3028 Turbo (CTS 2031 Turbo)) multiplexer is designed to be a
cost-effective point-to-point multiplexer. At the same time, it is fully compatible
with the CTS 2031 and the AT&T Paradyne DCX family of multiplexers and can
serve as an 8-channel node in a DCX network.

1. Remove the 3028 Turbo (CTS 2031 Turbo) from the box and place it on a
flat surface.
2. MODEM CONNECTION. Connect the supplied composite link cable to
the port labeled COMPOSITE on the rear panel (Figures 1-2) and then to
the modem. The Composite port is configured as a DTE to allow use of a
shielded, Male to Female, straight through cable to connect the Modem.
3. Connect the customer-supplied shielded, Male to Male, RS-232-C cables to
the selected ports and the DTEs, respectively.
4. The voltage selector is set to the proper line voltage for the area of the
world where the unit will be used at the factory. For the United States the
switch is set to 115V. Plug the female end of the power cable into the
receptacle on the rear panel and connect the other end to the power source.
The unit is operational when the POWER LED lights.
5. After the 3028 Turbo (CTS 2031 Turbo) has been attached to the proper
power source, it performs a series of tests to insure the integrity of the
system components. If the tests are passed, the multiplexer LCD displays:
20312-51
SYSTEM READY
00:00:00
and the system configuration can be performed. If any of the tests fail, the
LCD displays a message (refer to System Error Messages section). When
this message is displayed, cycle the power. If the error occurs again
contact your CTS service representative.
6. Connect a standard ASCII terminal, if used, to the 3028 Turbo (CTS 2031
Turbo) using a customer-supplied, straight-through, RS-232-C I/O cable at
the port labeled SUPERVISORY.
Note
Shielded RS-232-C I/O cables
