Data line cards interface various Data Terminal Equipment (DTE)
directly with D/I Mux III multiplexers, without the use of modems
for full-duplex transmission over T1 lines.
Software-programmable data line cards support synchronous data rates
of 1.2 Kbps to 1.536 Mbps, and asynchronous data rates from 1.2
to 19.2 Kbps.
D/I Mux III - ADCU Card
Coastcom's Asynchronous 0-19.2 kbps RS-232C and RS-422 Data Channel
Unit interfaces Data Terminal Equipment (DTE) directly with the
D/I Mux TDM multiplexer to provide
full-duplex transmission. The unit employs transitional encoding
to transmit asynchronous data at rates up to 19.2 kbps with a distortion
of less than or equal to 15 percent.
Typical Application
The typical application depicted below illustrates an RS-232
/ 422 communication via T1 over any distance with up to ten ADCU’s
sharing one DS0 (polled operation). ADCUs can also carry serial
data point-to-point without polling.

D/I Mux III - DSDCU Card
Dual Synchronous Data Channel Unit
Using state-of-the-art technology, Coastcom's new DSDCU is designed
to accommodate two high speed data channels on a single card, providing
a more convenient, economical solution than single channel models.
The DSDCU can be hardware optioned to provide V.35, RS-422, or RS-232
interfaces, and software optioned to support data rates of 56/64
Kbps x N (N = 1 to 24). Each channel can be independently mapped
to either T1-1 or T1-2, and provides both DDS and proprietary loopbacks.
Typical Applications
- LAN-WAN-LAN connections. Direct high-speed mainframe-to-mainframe
communications. Frame Relay transport. Fractional T1 (FT1) interface
for compressed video.
- The application below depicts a typical high-speed LAN-WAN-LAN
connection. A
company could have Local Area Networks (LANs) in several locations,
linked together in a Wide Area Network (WAN) using T1. Coastcom's
D/I Mux III ™ Intelligent Multiplexers equipped with DSDCU
cards are installed at each LAN site. Bandwidth can be adjusted
to regulate traffic flow as needed, facilitating rapid file
transfers between LANs.

D/I Mux III - SDCU Card
56/64
Kbps Synchronous Data Channel Units
Coastcom's Smart SDCU channel cards and D/I Mux III allow you to
expand your bandwidth from 56 Kbps up to 1.536 Mbps. The RS-232C
SDCU allows LAN to LAN connections, supplying one high-speed synchronous
data interface to the LAN. Several other versions are available
including 56/64K with either V.35 or RS-422, and 56/64K x N with
either V.35, RS-422, or RS-232 interfaces.
Typical
Applications
- LAN to LAN connections
- Synchronous data connections
- Split off high speed LAN data streams from mixed voice and
data T1 facilities.
- Direct high speed mainframe to mainframe computer communications.
- Reach disaster recovery sites, keeping your computer operations
up and running.
- Cost-effective Fractional T1 (FT1) interface for compressed
video conferences and other high speed equipment.
Feature Advantages
- In a bi-directional operation, the SDCU can be software reconfigured
to use either T1 port during a line failure.
- A complete set of diagnostic loopbacks are available including
remote, local, and line loopback.
- Unnecessary frequency adapters have been eliminated, ensuring
efficient installation.
- Provisioning options are both software and hardware controllable.
Provisioning
options include direction, CTS delay, and polling/non-polling
modes.
- The SDCU offers a wide range of bandwidth choices. 56 Kbps
data rate multiples go from 56K to 1,344K; 64 Kbps data rate
multiples go from 64K to 1,536K.
D/I Mux III - OCUDP Card
Office Channel Unit Data Port
Coastcom's All Rate Office Channel Unit Data Port (All Rate OCUDP)
programmable channel and interfaces data applications to T1 transmission
facilities.
The All Rate OCUDP provides access to the Dataphone Digital Service
from a D/I Mux III multiplexer. The All Rate OCUDP acts as a format
converter and a data speed buffer to provide all the necessary rate
and format conversions between the 4-Wire DDS loop and the T1 line
facility. The All Rate OCUDP transmits and receives data via a single
DS0 channel of a T1 line.
In the DDS system, an All Rate OCUDP located at the end office interfaces
the customer to the DDS network using a full duplex, synchronous
4-wire loop terminated at the customer site by a Data Service Unit
(DSU) or a Channel Service Unit (CSU).
Typical
Applications
- Allows for 72 Kbps links equipped with secondary channels.
- Extends distances beyond commonly supported V.35 and other
DSU devices. The SW56 Kbps OCUDP can transmit and receive at
up to 12,000 feet, while the All Rate OCUDP can transmit and
receive at up to 20,000 feet.
- Connect to public networks' switched 56 Kbps and DDS services.

SDM family for the D/I Mux III™ Intelligent T1 Multiplexer
lets you combine subrate data on a single DS0, eliminating modem
expense and maximizing your T1 investment. Whether your application
is point-to-point or point-to-multipoint in a private or public
network, the intelligent, programmable SDM cards are available in
four versions to suit your specific need.
Typical
Applications
- System Control and Data Acquisition (SCADA)

The SDM is typically used to provide up to five subrate data channels
within a single DS0 in a point-to-point network. Each subrate channel
can be individually programmed for asynchronous or synchronous at
data rates from 1,200 to 19,000 bps for proprietary mode, or 2,400
to 19,200 bps for DDS mode. The SDM reduces the response time and
circuit costs by eliminating separate DS0s.
