This module supports sync or async data, and TTL alarm inputs and relay
outputs:
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.
The HD-15 Alarm I/O connector supports two TTL alarm inputs and four
Form-C relay outputs.
• Individual alarm inputs are mapped to any output within a 9500 MXC 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 a 9500 MXC Node, to its IP address plus the slot location and
output number for the AUX plug-in.
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.
Alarm Outputs
Outputs are user configurable to be normally high or normally low. Default is
normally low (relay inactive). Additionally, a user can select on the Alarm I/O
connector, a normally closed or normally open contact pair.
For information on TTL input limits and relay output voltage and current
maximums, refer to Alarm I/O Port on page 2-5.
