The European EMC Directive (EN55022, EN50082-1) requires using properly shielded cables for DATA I/O.
These cables must be double-shielded from end-to-end, ensuring a continuous ground shield.
In addition to the connectors listed in Table 1-1, eight LEDs are provided on the rear panel:
•
Six of the LEDs, all orange, indicate the interface type currently selected: V.35, RS232,
RS422/EIA530, T1, E1-U, or E1-B.
•
For systems in a redundant configuration, a green LED labeled "Online" indicates the
Online/Offline status of the unit.
•
When the unit is connected to a 1:N switch, a red LED labeled "1:N CAUTION!"
indicates that caution is required, as there may be DC voltages and other control signals
present on certain pins on the 25-pin Data Interface connector.
Also associated with redundancy mode, a slide switch is provided that selects the 1:N mode.
