D/I Mux III Data 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.

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.

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.

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).

D/I Mux III - SDM and pSDM Cards

Subrate Data Multiplexer / premium Subrate Data Multiplexer Coastcom's 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




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.
