SX-2000 MICRO LIGHT System

The SX-2000 MICRO LIGHT system is a non-redundant configuration that can support up to

four expanded peripheral nodes or two DSU nodes.

The SX-2000 MICRO LIGHT node consists of the following components:

• Control cards: The SX-2000 MICRO LIGHT cabinet contains a

Main Controller card and

Control Resource card. The Main Controller card is located in slot 1 (PLID 1 1 1), and

the Control Resource card is located in slot 2 (PLID 1 1 2).

• Peripheral Switch Controller Card (PSC): The

Peripheral Switch Controller card per-

forms all the peripheral switch functions for up to twelve Peripheral Interface cards

(twenty-four with an expanded peripheral node). The PSC card is installed in slot 16 (PLID

2 1 16).

• Peripheral Interface Cards: The SX-2000 MICRO LIGHT cabinet holds up to eight

Pe-

ripheral Interface cards

. These cards join telephone trunks and peripheral devices (such

as SUPERSET telephones) to the system. The Peripheral Interface cards are located in

slots 4 to 11 (PLIDs 2 1 4 to 2 1 11).

• Digital Service Unit (DSU) Cards: The SX-2000 MICRO LIGHT cabinet holds up to four

DSU cards. These are intelligent cards that provide specialized digital functions. The DSU

cards are installed in slots 2 to 5 (PLIDs 3 1 2 to 3 1 5).

• CEPT (Committee for European Posts and Telegraph) Interface Assembly II: This

interface assembly provides four filtered BNC connectors (typically used with coax cable

for Ethernet, video, and RF signals) for the external digital trunks that connect to the CEPT

Formatter I and II cards. Most CEPT Formatter cards require a CEPT Interface Assembly

II (depending on system set up, sometimes an Interface Assembly may be used).

• Interface Assembly: This interface assembly provides RJ45 connection for the external

digital trunks that connect to the DS1 Formatter I and II cards.
