D/I Mux III Special Feature Cards
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. Coastcom has developed specialty cards that meet specific product
applications.
D/I Mux III - ADPCM2 Channel Card
ADPCM voice compression enables the Dual 4-Wire E&M channel cards to reduce the
transmission rate to 32 kbps, thereby allowing two voice channels to be carried
on a single 64-kbps DS0 link. The ADPCM card is configured to accommodate two
intertoll trunks, as depicted in the graphic. The compressed voice signals used
in the ADPCM cards are virtually indistinguishable in quality from the original,
uncompressed voice signals. Coastcom’s ADPCM Dual 4-Wire E&M channel cards in a
D/I Mux III™ network effectively reduce voice-traffic bandwidth and thereby
increase your network’s carrying capacity. Using an Adaptive Differential Pulse
Code Modulation (ADPCM) algorithm, the Dual 4-Wire E&M cards double the number
of phone lines from the original 24 64-kbps channels to 48 32-kbps channels
carried by a T1 span.
Typical Applications
In typical applications (illustrated above), the ADPCM cards work in conjunction
with
Coastcom's other channel cards in a D/I Mux III network to integrate diverse
services. By consolidating voice circuits, the ADPCM cards free up space on your
leased line for the transmission of other media, such as data or video.

D/I Mux III - TTU Card
Tandem T1
Unit Coastcom's Tandem T1 Unit provides an additional T1 interface. The D/I Mux
III dual T1 multiplexer supports two trunk T1 interfaces. With the TTU, you can
add extra T1
interfaces as you would channel units.
Typical Applications
Feature Advantages
D/I Mux III - Video Encoder/Decoder Cards
Tandem T1 Unit
Coastcom’s Video Encoder/Decoder Channel Cards provide D/I Mux III™ Intelligent
T1 Multiplexer users with the video component of a fully functional voice and
data system without requiring an external CODEC. The cards allow throughput of
real-time video with a minimal bandwidth requirement. With transmission rates of
64 kbps to 1.544 Mbps and up to 30 frames per second, each easy-to-program card
can be configured to use as little as one DS0 or a full T1 line for maximum
image quality.
A typical transportation application can include a strategically placed video
camera, road sensors, and pan-and-tilt devices to monitor traffic flow along a
stretch of heavily used highway. Video monitors in the traffic control center
provide managers of advanced traffic-management systems with the information
they need to dispatch emergency equipment in response to an accident or to
acknowledge a traffic slowdown as routine congestion.
Typical Applications
A typical videoconferencing application can include Video Encoder/Decoder
Channel Cards, video cameras, PCs, and audio equipment connected to D/I Mux IIIs
at each site. Here a company with offices in Houston and Chicago use
videoconferencing to enhance communication and promote employee interaction.

D/I Mux III – Fiber Interface Network Device (FIND)
Coastcom’s Fiber Interface Network Device (FIND) plugs into new or previously
installed D/I Mux III systems to reduce costs and increase T1 transmission
distances. With a range of up to 80kms, the FIND eliminates costly T1 repeaters
and increases noise immunity.
FIND handles up to 2 bi-directional T1 lines which can both be fiber or one
fiber T1 and one copper T1, respectively. Installation is a snap. Merely plug
the channel card in and connect the spans. No programming necessary. No set up.
No delay.
Lose nothing. Gain much.
While providing copper and fiber transmission, no D/I Mux features are
sacrificed. FIND supports ALPS (Automatic Loop Protection Switching) mode, dual
channel bank mode, and drop-and-insert mode. The Coastcom FIND adds 1:1
protection of the fiber span when used in dual T1 point-to-point configuration.
In channel bank mode, the fiber interface module provides APS (Automatic
Protection Switching) of fiber connections between D/I Mux systems. Switching
time between spans is less than 50msec. In fact, the APS function can be used on
a fiber span connected to T1-1 while simultaneously, T1-2 is operating over a
copper span.
