The SX-200 EL and the SX-200 ML cabinet hold a main control card and a bay control card with peripheral interface cards in slots one to eight. The SX-200 SPINE holds a peripheral control module and a power module with Loop Start (LS) trunks and LS/CLASS II modules, ONS, DNIC and CLASS modules.
The SX-200 LIGHT Peripheral cabinet has up to four high-power digital peripheral cards which can only plug into upper card slots; low-power digital peripheral cards can plug into upper or lower card slots. The SX-200 rack mount cabinet used for the SX-200 EL and SX-200 ML supports up to four high power cards which may be plugged into any slots; low-power digital peripheral cards can plug into the remaining card slots.
The high power cards have the ! symbol on the face of the peripheral interface card. The low power cards have the

symbol on the face of the peripheral interface card.Universal Card !
The Universal Card is a high power card that holds up to four modules. If more than the seven receivers provided by the Main Control Card are required on a system, a Universal Card and one or more Receiver Modules must be installed. Each module is assigned a power rating. The cumulative ratings of the modules on the Universal Card cannot exceed a value of 10. The modules are as follows:
• Receiver/Relay Module (contains four DTMF receivers and two relays) (power rating = 2) • Music-on-Hold/Pager Module (contains one music input, one PA paging output) (power
rating = 1)
• E&M Trunk Module (contains one E&M trunk) (power rating = 3) • LCD Console Interface Module (power rating = 5)
ONS/CLASS Line Card
•
The ONS/CLASS Line card is a low power card and replaces the ONS Line card. The card has the same functionality as the ONS Line card and if software enabled, offers CLASS functionality. The ONS/CLASS Line card has 12 DTMF/Rotary line circuits per card. The card accepts up to three industry-standard DTMF/Rotary telephone sets per line circuit. The card interfaces the telephone analog input with the system’s digital crosspoint network. It converts the analog telephone signals into the digital format used by the system, and converts the digital information back into the analog signals required by the telephone sets.
The ONS/CLASS Line card is backwards compatible.The card provides the ONS Line functionality as a default to the SX-200 DIGITAL, the SX-200 LIGHT, the SX-200 ML (FD), the SX-200 EL and the SX-200 ML systems. The CLASS functionality is enabled by a purchasable MOSS option and is only offered to the SX-200 EL and the SX-200 ML systems. CLASS also requires LIGHTWARE 18 Release 2.0 or greater and an SX-200 ELx cabinet with a BCC III holding a DSP module (single). The ONS/CLASS Line card must reside in the same cabinet as the BCC III.
Digital Line Card
•
The Digital Line Card (DLC) is a low power card with 12 Digital Network Interface Circuits (DNIC) per card. The Digital Line Card interfaces DNIC-based peripheral devices to the system through its Digital Network Interface Circuits (DNIC); the DNIC is a proprietary integrated circuit. DNIC devices include SUPERSET 4001, SUPERSET 4015 , SUPERSET 4025, SUPERSET 4125, SUPERSET 4150, SUPERSET 4090, SUPERSET 401+, SUPERSET 410, SUPERSET 420, SUPERSET 430 telephones, Programmable Key Modules, DATASETs,
SUPERCONSOLE 1000 Attendant Console, DMP Module, and SUPERSET 7000 Attendant Consoles.
LS/GS Trunk Card
•
The LS/GS Trunk card is a low power card that contains six loop start or ground start trunks (jumper-selectable) and six message registration inputs. The card may be installed in any digital peripheral slot. Facilities provided by the LS/GS Trunk Card include: Loop Start or Ground Start selectable by jumper, M and MM signaling leads (refer to the feature, Meter Pulse Collection), trunk activity indicated by LED (one per trunk), transient suppression on Tip, Ring, and signaling leads, and an alarm LED.
LS/CLASS Trunk Card
•
The LS/CLASSTrunk card interfaces eight trunk circuits to the system. LS is the acronym for Loop Start and CLASS is the acronym for Custom Local Area Signaling Services (allows the system to receive calling Line ID digits and CLASS name on incoming CLASS trunks). The LS/CLASS Trunk card can be installed into slots one to eight in a SX-200 rack mount cabinet or a SX-200 ML (FD) cabinet. The card is dependant on LIGHTWARE 19 Release 2 or greater software. The LS/CLASS Trunk card provides loop start operation, forward/reverse current detectors (polarity reversal, answer supervision), alarms and trunk activity indicated by an LED (a single LED for any circuit in use), CLASS signal reception, and transient suppression on Tip and Ring leads.
Direct Inward Dial (DID) Trunk Card !
The DID trunk card is a high power card that contains six 1-way Direct Inward Dial circuits. The DID trunk allows incoming trunk calls to dial directly to an extension within the system without attendant intervention.
Off-Premise (OPS) Line Card
•
The OPS line card is a low power card that interfaces the system to extensions which are part of the system, but are located in a different building from the PBX. It contains additional protection circuitry to protect the system from extraneous high voltages or induced currents that may appear on the line. Each OPS card has six circuits.
COV Card !
The COV card is a high power card that is required to interface to certain voicemail applications.
Mitel Express Messenger Card
•
The Mitel Express Messenger card is a low-power card. The card uses a DNIC interface that connects directly to the backplane of the cabinet.The card provides either two, four, six, or eight voice mail ports to an SX-200 EL/ML system that has Release 1.1 software or later.
BRI Card
•
The BRI card is a low power card, although there is a maximum limit of two cards per cabinet. The card allows the SX-200 to communicate to Central Offices and devices that support BRI (Basic Rate Interface). The SX-200 supports the termination and the origination of ISDN voice and data calls for trunk side and line side U interfaces. The trunk side provides Basic Call and Incoming Calling Name. The line side provides data and voice calls from BRI devices, and voice calls from sets. The BRI card provides up to 12 ISDN BRI U interfaces.
LS/CLASS Trunk Module
The LS/CLASS Trunk module mounts in any slot of the SX-200 SPINE and interfaces four trunk circuits to the system. It includes circuitry to switch trunk circuit 1 to a SFT telephone set during power or system failure.
DNIC Module
The Digital Network Interface Circuit (DNIC) module interfaces up to four DNIC devices to the SX-200 SPINE.
ONS Line Module
The ON-Premises (ONS) line module interfaces up to four industry-standard DTMF telephone sets within the building to the SX-200 SPINE.
