Unless otherwise stated, ATM and WAN interfaces provide two input ports and
two output ports allowing any one of the following connection configurations
to be used:
• Terminal Mode - uses one input and one output
• Bridged Monitor Mode - uses both inputs and outputs for bi-directional
monitoring at test access points; a high input impedance should normally be
selected
• Monitor Jack Mode – uses both inputs only for bi-directional monitoring at
protected monitor points
• Through Monitor Mode - uses both inputs and outputs providing bi-directional
repeater functionality plus bi-directional monitoring functionality. Each
receiver input is terminated. The insert mode can place test traffic like SLA,
PING, LMI emulation, Traffic Generation and Simulation.
The operation of the physical interface is often critical in determining the cause
of network problems. Therefore, the Advisor tracks errors at the physical layer,
and it stamps the information with a 1 ms time stamp. Signal events are
recorded on the display for both the line (network) side as well as the
equipment (user/subscriber) side. The time of the last occurrence of a
particular event is recorded as well. Events are saved in the buffer and can be
logged to disk.
Line status is displayed in real time. All of the events listed in the “Physical layer
alarms and statistics” section for each interface below are saved in the buffer
and counted in the line status display. These events may be logged to disk.
Critical parameters marked with an asterisk (*) are also displayed in large green
or red boxes in the line status display for easy “at-a-glance” viewing.
V-Series Interfaces (Integrated in the J2300E)
General
V.10/V.11, V.24/V.28/RS-232C, V.35 and V.36/RS-449/422/423 are built into the
J2300E mainframe; X.21 (with J2277A external cable – V.36/RS-449 to DB15)
and RS-530 (with external cable J2278A – V.36/RS-449 to DB25) are also
available.
Note: The interface J5457A provides V.35, RS-449 and X.21 interface operations
up to 8.192 Mb/s.
