Peripheral Interface Cards and Modules
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

The low power cards have the

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.
