OHSU Card

The 8000-OHSU-4P card allows the connection of IEEE C37.94 compliant teleprotection
equipment to WAN links. OHSU cards can be installed in any of the User Slots in an
Integrated Access System chassis.
The OHSU Card contains four IEEE C37.94 compliant optical interface ports. These ports are
designed to function as the multiplexer equipment end of the interface.
Designed to C37.94 requirements, the OHSU ports are the timing source for the optical links.
Each port of the OHSU allows the user to map the payload (up to 12 x 64kbps) of the C37.94
link onto the IMACS WAN link.
Software-initiated diagnostics support includes the setting of local loop backs towards either
the network or the attached teleprotection equipment.
The current optical link status can be checked using the OHSU main screen and the LED for
each port on the front panel.

SRU Card

The 8000-LDSRU-10P card enables high density connectivity for local, synchronous or
asynchronous peripherals. The SRU Card allows connections of up to ten RS-232, low-speed
and medium-speed (300 bps to 38.4 kbps) data terminals to the Integrated Access System.
