RAD Data Communications 2009 Catalog
While many vendors are terminating their legacy 
multiservice TDM products, RAD Data 
Communications continues to offer carriers, telecom 
operators and service providers a winning TDM 
service deployment strategy. This enables them to 
speed their return on investment in access network 
equipment and Local Loop plant, as well as to 
facilitate the rollout of a variety of new services. 
Most importantly, carriers can quickly generate 
income without incurring substantial infrastructure 
costs, while assuring migration to next-generation 
networks.
RAD’s TDM Multiservice Access Platform (MAP) is based 
on deploying specialized equipment at the customer 
premises, in the Local Loop and at the carrier’s 
point-of-presence (POP). The MAP product family includes 
the FCD range of dedicated multiservice network 
termination units as well as the Megaplex line of 
multiservice access multiplexers (TDM, IP and Frame 
Relay) and the DXC series of multiservice access nodes. 
All products offer built-in Last Mile solutions, such as 
IDSL, SHDSL and fiber optics. The Kilomux integrating 
multiplexer complements the MAP family, addressing 
bandwidth-constrained applications in the transportation, 
utility and government markets.
The DXC family of modular multiservice-access nodes 
provides non-blocking DS0 cross connect for up to 688 
E1/T1 lines. Most of the DXC units support built-in Local 
Loop solutions. The DXC devices are the most compact 
and high density cross connects of their kind. Plug-in 
interface modules supporting n x 56/64 kbps, ISDN U, E1 
or T1 transmission with built-in IDSL, SHDSL and fiber 
optic modems, E3/T3, STM-1/OC-3 are available. Inverse 
multiplexing capabilities for up to eight E1/T1 lines 
support high speed data, native LAN connectivity and 
video streaming applications.
The FCD-155E and FCD-155 offer STM-1 ADM or terminal 
capabilities. They provide a robust and resilient alternative 
to access network extension in the carrier environment, 
offering bandwidth-efficient provisioning of Ethernet 
services on top of traditional TDM interfaces. It is a quick, 
cost-effective alternative for service deployment for 
utilities and transportation authorities.
RAD’s Megaplex family of multiservice access 
multiplexers offers a wide range of data, LAN and voice 
services. The devices come with a wide variety of analog 
and digital voice connections – PCM, ADPCM, G.723.1, BRI 
ISDN, and digital E1/T1 interfaces. These include tail-end 
modems and up to 80 E1/T1 lines for distributing 
different services over the same infrastructure and 
splitting these services at the POP. They also include 
built-in fiber optic and five SHDSL and SHDSL.bis main 
trunk modems. The Megaplex-4100 offers a future proof 
migration path to Ethernet. It serves as a central solution 
for Ethernet access devices as well as for TDM CPEs. It 
also combines STM-1/OC-3 capabilities with DS0 cross 
connect. 
The FCD family of compact, low cost, multiservice 
network termination units (NTUs) extends the E1/T1 
network to the customer premises, enabling carriers and 
service providers to create a flexible, service independent 
access model while offering a competitive and wide 
service portfolio.
Finally, RAD’s Optimux fiber multiplexers enable easy 
Ethernet and PDH extension over fiber links or service 
port fan-out off large capacity switches and ADMs for 
improved access deployment flexibility. Ranging from a 
few E1/T1s with or without Ethernet up to STM-1/OC-3 
capacity, they offer a solution for every service extension 
scenario.
RAD’s Kilomux is a subrate multiplexer for data, voice, 
fax, and LAN. It integrates a variety of traffic types over 
leased lines, ISDN, IP, and fractional E1/T1, over copper or 
fiber, at rates of 9.6 kbps to 1,536 kbps.
Combining award-winning, high quality voice compression 
techniques with maximum bandwidth utilization and a 
wide range of network and user interfaces, the Kilomux 
provides reliable point-to-point and drop-and-insert data/
voice integration solutions at an affordable price, 
particularly attractive to the transportation, utilities and 
governmental markets.
