OPERATION
Inputs: The OmniRepeater 400 is built around a Digital Phased
Locked Architecture (PLA). This technology allows effective
discrimination between true data and noise. The incoming
Manchester encoded data is sampled at 16 samples per bit, which
facilitates digital filtering of noise and crosstalk. A unique clock
recovery facilitates the capture of data with rate variations of -2%
to +4%.
Processing: Once the data is recovered and synchronized, it is
processed. The processor analyzes the frame header. If a legal
header is detected, the port is “marked” active and the data is
allowed to flow through the repeater.
Outputs: The retransmitted data is regenerated, reclocked and
lost sync bits are recovered. The data is reclocked at 50% duty
cycle to eliminate clock jitter. The signal is restored to nominal
amplitude and the pre-distortion logic compensates for
anticipated phase shift and attenuation.
Displays: True data activity and parity errors are displayed by
green and red LEDs. The green activity LEDs assist in monitoring
signal strength while the red Parity Error LEDs assist in
monitoring connectivity quality, signal strength, impedance
mismatches and reflections.
SAMPLE APPLICATIONS
The following picture depicts three typical applications of the
OmniRepeater
400:
In the first case, the host (a) twinax signal is repeated and reclocked
by the OmniRepeater (b) and workstation distance from the host
is extended to 10,000 feet (c).
In the second case, the OmniRepeater (d) converts the twinax data
to fiber and then back to twinax via a second OmniRepeater (e).
In the third case, twinax is converted to fiber (g) via the
OmniRepeater
and then to twisted pair via an OmniMux ™ (h)
which delivers it to the workstations (k).

ORDERING INFORMATION
Standard 5250
5250 Express Description
2651 2661 Twinax to Twinax and Fiber
2653 2663 Twinax to Twinax Only
while providing superior noise and crosstalk immunity.
The Express models operate with both the 5250 and 5250 Express
protocols. Each port provides data rates of 1 Mbps for standard
5250 and 2 Mbps for 5250 Express protocol.
The OmniRepeater 400 is completely software-transparent and
no setup or any changes are required.
