The sister board has its own terminal blocks and can support any legacy DS0, including: Audio,
G.703, RS-422, RS-232, V.35, contact closures, or additional C37.94. The sister board can support
up to six DS0s, depending on the space available for interconnections on the back of the unit. Due
to the many possible combinations that can be supported, the customer must contact Iniven in order
to specify what I/Os they require. A dash number will be assigned to their configuration to make
repeat orders simpler.
The CC-500 is designed for applications such as protective relaying and environments where
substation hardened equipment is required.
The CC-500 has limited programmability. It has been designed as a plug-and-play system.
Programming is limited to turning off unused channels via DIP switches, selecting the backhaul, and
specific settings for the sister board, which will change according to configuration. Communications
through the CC-500 are transparent.
T1 and fiber signal monitoring is a included on all units. The CC-500 displays the status of the
channels using LEDs on the front panel and utilizes relays for remote monitoring.
The enclosure is a 17.25 inch wide, 1 Unit high (1U) chassis by 9.2 inches deep. The chassis is
equipped with mounting brackets for a standard 19 inch rack. Mounting brackets for 23 inch racks is
available as an option.
All indicators and DIP switches are located on the front of the chassis. All wiring, including
communications, power, and alarm connections are on the rear of the chassis.
FEATURES
DESIGN: The CC-500 has been designed for ease of setup and use. Each CC-500 is equipped with
four C37.94 channels. These may be multimode, singlemode, or a combination of both. The unit’s
design allows for quick system monitoring and diagnosis.
PROGRAMMABILITY: Programming is performed using two 10 position DIP switches located on the
front panel of the unit. This is currently limited to turning off unused channels via DIP switches, selecting
the backhaul, and specifying settings for the sister board, which change based on the configuration.
Turning off unused channels prevents unwanted alarms. There are unused DIP switches, which are
reserved for future options that may be required by customers. The unit is designed to be plug-and-
play. Iniven can modify any of the T1 settings at the factory to accommodate the local T1 requirements.
COMMUNICATIONS: The CC-500 converts multiple audio signals, contact closures, C37.94, or other
DS0 signals to a digital backhaul. The backhaul can be point-to-point fiber or electrical T1. The T1
interface does not make the CC-500 a T1 multiplexer, but rather a converter. A T1 channel needs
to be in place for the unit to communicate using the T1 backhaul. Typically, this would consist of a
leased T1 channel from a local telephone company. The T1 interface is an RJ-48 female connector.
The standard CC-500 uses the T1 line format, B8ZS and the T1 frame format, ESF. Iniven can modify
any aspect of the T1 format at the factory. The CC-500 will support a T1 channel that lacks clocking
by syncing from its own signal.
