Tel-Link Radio System, operating at frequencies from 15
GHz to 38 GHz, provides a cost-effective and immediate
solution to voice and data transmission requirements in
capacities from 1T1 to 16T1 and DS3. The Tel-Link Radio
System is available in both protected and non-protected
configurations.
Consisting of an Outdoor
Unit (ODU), an Indoor Unit (IDU), and a single coaxial
cable for the ODU-IDU interconnection, the Tel-Link
system is ideally suited for networks operated by
personal communications and cellular service providers,
utilities, public telephone network operators, local
governments and private users.
One Rack Space High
IDU
The new one rack space
high IDU provides enhanced features in less space while
retaining compatibility with previous models. The IDU is
common to all Tel-Link frequency bands. It contains all
the baseband electronics including line interfaces,
digital multiplexing, modulation and frequency
generation, alarms and diagnostics, service channel and
network management interfaces.
The 16-button key-pad
with backlit LCD provides easy access to major
parameters such as transmit power, Received Signal Level
(RSL), and operating frequency, via a single key.
Implementation
flexibility is provided through the use of a wide-input
power supply (±20-60 VDC). The IDU requires no fans for
cooling, further simplifying implementation and
improving reliability.
At applicable
frequencies, the IDU offers switchable modulation
between 2-FSK and 4-FSK, providing the user with the
flexibility of backwards compatibility with existing
equipment.
Advanced Software
Downloadable software
allows firmware enhancements to be made without the need
for hardware changes. Enhanced software commands provide
the capability to display transmit frequency in MHz,
fade margin in dB, and output power and RSL in dBm.
A user configurable RSL
alarm allows notification of a decrease in RSL to a
predetermined point, e.g., approaching threshold.
Software commands allow users to automatically calculate
link fade margins.
Ease of Installation
Tel-Link radios offer the
industry's simplest and easiest installation. No tuning
is required at installation. Only the azimuth and
elevation need to be set and these adjustments are
performed with a simple voltmeter.
Network Management
The Network Management
System (NMS) architecture allows for connection to the
P-Com NMS or can be easily adjusted to the user's
existing NMS platform. Additionally, the system can be
configured with dial-out capability, allowing it to dial
out over a standard telephone line and send a message
containing site ID and alarm information to a user's
network operations center. Sophisticated built-in
diagnostics deliver a low cost of ownership.
