For air traffic controllers, nothing can be as critical as maintaining constant contact with
airport's radar sites. That may be harder than it first seems. In addition to radar itself, the
sites will include telephones, and all have to be connected to the main air traffic control
(ATC) center. But remote sites may not require a full E1/T1. In this case, a multiservice
multiplexer that supports fractional E1/T1 leased services is required.
RAD Data Communications offers a complete yet simple and scalable solution for
connecting all such services over leased time division multiplexing (TDM) channels. RAD's
Kilomux-2104 sub-rate multiplexers can be deployed at remote radar sites and other
communications centers to combine data and voice, as well as fax and LAN traffic, over
fractional E1/T1. This traffic is then sent over leased TDM channels. At the ATC facility,
incoming E1/T1 lines are connected directly into RAD's DXC-10A/8R cross connect, which
separates them back into fractional E1/T1 lines for Kilomux-2100 or smaller Kilomux-2104
units to distribute to radar monitors, a central PBX or dispatch phones.
The Kilomux also transports voice and data over digital data services, ISDN, IP, and
fractional E1/T1 lines on any kind of access media: copper, fiber, radio, microwave, or
satellite. Kilomux multiplexers use TDM to ensure minimal delay and protocol transparency.
An optional TDMoIP® pseudowire module allows legacy TDM traffic to be transported
transparently over packet-switched IP or Ethernet-based networks.
The Kilomux's flexible modular chassis enables quick deployment of various data and voice
services, its advanced voice compression maximizes bandwidth utilization to save on costs
and its minimal end-to-end delay supports high-quality satellite communications.
A wide variety of interfaces are available on the aggregate links for compatibility with
digital data services. These include V.35, V.36/V.11, RS-530, V.24/RS-232, X.21, and G.703
co-directional. Built-in fractional E1/T1, CSU/DSU, fiber optic, and ISDN terminal adapters
are also available. Soft-selectable timing options from either the link or any channel are
standard for all interfaces, as is support for control signals.

The Kilomux-2100 supports a secondary link, which can be configured as a backup link, as an active, secondary link with load-sharing option providing double capacity or as an additional, active link, enabling communication with two independent Kilomux-2100 units at different sites.
RAD's DXC-10A digital cross-connect node provides digital access and cross-connect for multiple services. The point-to-multipoint DXC-10A can broadcast any traffic combination from a single input to numerous destinations and provides non-blocking cross-connect for up to 120 lines. The modular DXC-10A supports E1/T1 conversion, inverse multiplexing, signaling monitoring, grooming of fractional traffic, and the transmission of T1 circuits over E1 lines. Services supported include n x 56/64 kbps, E1/T1, E3/T3, ISDN, xDSL, and STM-1 over copper, fiber or xDSL media.
To ensure maximum system reliability, the DXC-10A digital cross-connect node can be
equipped with full or partial redundancy and protection solutions. The compact, 1U-high
DXC-10A supports up to 40 ports.
