Trib Ber Measurement - Harris Stratex Eclipse 4.6 User Manual

• Ethernet Performance Screens
• History Screen: Ethernet
Wayside Traffic Module
The Wayside Traffic Module supports 8xE1 or 8xDS1 tributary circuits. Each is
accessed on an RJ-45 connector.
• For an E1 selection, options are provided for 75 ohms unbalanced or 120 ohms
balanced.
• For a DS1 selection, options are provided for AMI or B8ZS encoding and line length.
Line impedance is 100 ohms balanced.
• The module supports trib and radio facing loopbacks, AIS insertion, and a PRBS
generator and receiver for trib BER measurement.
• Line isolation and surge protection are included.
Auxiliary Data and Alarm I/O Module
This module supports sync or async data, and TTL alarm inputs and relay outputs:
Auxiliary Data
The DB-9 AUX Data connector supports one synchronous or asynchronous auxiliary
data channel, which may be used to transport 3rd party NMS (or other data):
• Synchronous conforms to TIA/EIA-422 / V.11 at 64kbps, with selectable clock. The
source of the transmit clock can be set to internal (provided by IDU ES) or external
(provided by the user). For an external clock, channel synchronization is supported
by a selectable clock phase (rising or dropping edge of the clock pulse).
• Asynchronous conforms to TIA/EIA-562 (electrically compatible with V.24)
• Asynchronous rates are 1200, 2400, 4800, 9600, or 19200 bps, with parity and stop
bit selection.
Auxiliary data is transported within the link overhead, which is shared with NMS data.
Alarm I/O
The HD-15 Alarm I/O connector supports two TTL alarm inputs and four Form-C relay
outputs.
• Individual alarm inputs can be mapped to any output within an Eclipse network.
Similarly, individual internal events can be mapped to any output.
• Multiple input or internal events may be mapped to a common output. Mapping is
achieved using IP addressing for the destination IDU ES terminal, or if the
destination is an Eclipse INU/INUe, to its IP address plus the slot location and
output number for the AUX plug-in.
• Individual alarm inputs and relay outputs can be named. A severity level can also be
assigned to alarm inputs.
Alarm Inputs
The active state of each TTL alarm input is configurable to be active if the voltage on the
input is high, or active if the voltage is low. The alarm software detects a change in the
state of each input circuit, and raises or clears an input accordingly. The nominal alarm
polling rate is 1 second.
