DSX-80/160 Station Cards
DSX-80/160 16 Port Digital Station (16ESIU) Card
Each 16ESIU Card connects 16 digital extensions (i.e., DSX keysets). The 16ESIU has a Mode Switch (for
taking the card out of service). It also has a status LED that indicates proper card operation — as well as a
port activity LED that flashes faster as traffic on the card increases. You can install up to two 16ESIU Cards
in a DSX-80. You can install up to six 16ESIU Cards in a DSX-160. See System Configuration (page 19) for
more.
Tips to remember:
• In DSX-160, you must install a separate power supply for every two 16ESIU Cards installed.
• In both DSX-80 and DSX-160, you must install a 16ESIU Card in slot 1.
• You can install additional 16ESIU Cards in any slot.
DSX-80/160 16 Port Analog Station (16SLIU) Card with HV Message Waiting
The 16SLIU Card connects 16 analog extensions which are typically used for single line telephones and fax
machines. Just like the 16ESIU Card, the 16SLIU Card has a Mode Switch (for taking the card out of ser-
vice), a status LED indicating proper card operation, and a port activity LED to indicate traffic on the
card.See System Configuration (page 19) for more.
Tips to remember:
• The 16SLIU Card provides high voltage message waiting for single line sets with high voltage mes-
sage waiting lamps.
• The 16SLIU Card also provides Caller ID to single line sets.
• You can install a 16SLIU Card in any slot except slot 1.
