DSX 80/160 Line & Station Cards

The CPU Card is the system’s control center. It provides the system’s Linux operating system, central processing, stored program, and memory for the customer’s site-specific data. Every system requires a CPU Card. In addition, it also provides:
- CompactFlash card interface (for IntraMail, software loading, and database backup)
- Conference circuits, DTMF receivers and DTMF generators
- Real Time Clock
- NAND Flash for storing the system database
- Battery for short term (14 day) backup of the Real Time Clock and station parameters
- Two audio inputs for Background Music and Music on Hold (1/8” mono minijacks)
- One audio output for External Paging (1/8” mono minijack)
- Ethernet and USB ports for local and remote PC Programming
- RS-232 serial port for Station Message Detail Recording
- Built-in V.32BIS 14.4K BPS modem for remote maintenance

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.

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.

The 8COIU Card supports 8 analog loop start CO lines. The card has a Mode Switch (for taking the card out of service), a status LED indicating proper card operation, and a port activity LED that indicates traffic on the card. Each 8COIU Card also provides two power failure cut-through circuits. When commercial AC power fails, the card automatically cuts through two line circuits to two power failure single line telephones.

The 16COIU Card supports 16 analog loop start CO lines. The card has a Mode Switch (for taking the card out of service), a status LED indicating proper card operation, and a port activity LED that indicates traffic on the card. Each 16COIU Card also provides two power failure cut-through circuits. When commercial AC power fails, the Card automatically cuts through two line circuits to two power failure single line telephones.

The 8SLIU Card connects 8 analog extensions which are typically used for single line telephones and fax machines. The 8SLIU Card has a Mode Switch (for taking the card out of service), a status LED indicating proper card operation, and a port activity LED to indicate traffic on the card.

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 service), a status LED indicating proper card operation, and a port activity LED to indicate traffic on the card.

The T1/E1/PRI Line Card provides T1 advanced digital calling and gives the DSX-80/160 a maximum of 24 trunks in a single card slot. The available T1 line types include:

• Loop Start (DTMF and Dial Pulse)
• Ground Start (DTMF and Dial Pulse)
• Direct Inward Dialing (DID) Wink Start (DTMF and Dial Pulse)
• Direct Inward Dialing (DID) Immediate Start (DTMF and Dial Pulse)
• E&M Tie Line Wink Start (DTMF and Dial Pulse)
• E&M Tie Line Immediate Start (DTMF and Dial Pulse)
  

Tips to remember:

• Normally you connect the T1/E1/PRI Card to a separately-purchased Channel Service Unit (CSU).
• Use a standard straight-through CAT 5 cable to connect the T1/E1/PRI Card to the CSU. The CSU in turn connects to the telco smart jack.
