D/I Mux III FXS/FXO Channel Cards
Foreign Exchange Subscriber / Office Coastcom's family of Dual and
Quad FXS (Foreign Exchange Subscriber), and Dual FXO (Foreign Exchange
Office) channel cards for the D/I Mux III ™ Intelligent T1
Multiplexer can be configured to handle a variety of applications,
and offer years of trouble-free, cost-effective operation. The smart
QFXS combines reliability and performance with greater capacity.
Typical Applications
- WATS/800 services
- Private Line Automatic Ringdown (PLAR)
- Plain Old Telephone Service (POTS)
- Dial Pulse Termination (DPT)
- "800" incoming/outgoing
- Foreign Exchange Office
The FXS/FXO channel units are typically used in applications where
Plain Old Telephone Service (POTS) is provided to remote locations.
This could be from a Central Office (CO) switch to the user, or
as an Off Premises Extension (OPX) from a Private Branch Exchange
(PBX). The FXS unit provides the loop circuit and ringing to the
telephone at the remote location. The application shown depicts
the FXS as a Digital Pulse Termination (DPT) device for direct access
of PBX extensions from the public network.

D/I Mux III - MX Series
Digital Phone Extender
for Northern Telecom's Meridian™ Digital Deskset Coastcom's
MX series for the D/I Mux III Intelligent Multiplexer enables Northern
Telecom Meridian™ users located off-premise to have a fully
functional digital deskset. The extender is completely transparent
to the user and extends the features and functions of the Meridian
2000 Series Digital Deskset over virtually any distance, allowing
you to connect branch offices to the main office.
Typical Applications
- Extend Feature Sets Anywhere: Saves money by combining Off-Premise
Extensions (OPXs) onto a T1 line, retaining all features of
the digital desksets.
- Connect Branch Offices to Main Offices: Provides the unique
features and functions of digital desksets.
- Set up Branch Office ACD Agents: Allows remote users who
need digital deskset capabilities to function effectively.
The typical application depicted in the graphic above would allow
a headquarters office to
connect a branch office to the main PBX. Digital Deskset features
and functions are extended over any distance via a T1 connection
to the remote site, allowing users to have access to / from the
headquarters PBX. Additional voice and data services, such as videoconferencing
and LAN connectivity, can also be provisioned through the D/I Mux
III.

D/I Mux III - SO/S Card
Smart Omni OrderWire/Station Coastcom's Smart Omni Orderwire/Station
(SO/S) Channel Card and the D/I Mux III make network maintenance
easy.
Typical Applications
- SO/S permits voice communication in both directions on a
"party line" basis
with all other units on a single DS0 in point-to-point and drop/insert
networks.
It works directly with a 2-Wire DTMF telephone.
- OrderWire channels allow the network manager to call several
locations at once. Directions can be given to one location and
results observed at another to facilitate servicing.
Feature Advantages
- Traditional orderwire circuits require that you call every
station in a network.
Coastcom's smart Omni Orderwire units provide the flexibility
to contact just one
station using a customer's assigned address, or all stations
that share the same address.
- Communicating with a station is as simple as dialing the
customer assigned address number followed by a '#'. Addresses
are assigned by software and can range from 1 to 999 to handle
large networks. Any and all addresses may be active at the same
time in the same conversation.
- Coastcom's built-in quiet circuit helps eliminate accumulated
noise.
- A 2-Wire RJ-11 jack interface eliminates the need for special
4-Wire telephones. Off hook, ringing, and DTMF (touch tone)
dialing are supported.
- The system offers the flexibility to wire a telephone with
the standard T/R connector or a standard "modular phone
jack" (RJ11) on the front panel.
- A station can signal calls with an on-board "Sonalert"
or 20 Hz ringer.
- All options on the card can be remotely provisioned from
a system control terminal.
