OCU-DP Card
Overview
Overview
The Single Port and Quad Port all-rate OCU-DP Service Cards provide electrical and
physical termination of the 4-wire Digital Data Service (DDS) that is traditionally used
to interconnect lower-speed serial synchronous Data Terminal Equipment (DTE)
devices such as routers, Frame Relay Access Devices (FRAD), or video conferencing
equipment. Now DDS can be integrated with DS0 voice, fractional T1 data, ISDN, and
IP services – over multiple T1s or DS3s. This enables service providers to deliver
transport for legacy enterprise data networking or Common Channel Signaling (CCS)
circuits commonly used in Signaling System 7 (SS7) telephone networks using one
card for all standard DDS types. Plus, it can be used as a replacement for low-density,
unmanaged D4 channel banks.
The OCU-DP Service Cards provide scalable, independently configurable,
synchronous data service rates from 2.4 Kbps to 64 Kbps, including Switched 56 Kbps
data rates. Up to eight OCU-DP cards can be inserted into any of the service card slots
of the Axxius 800, providing up to 32 DDS connections. These cards enable industry-
leading density and cost per port at Central Offices (COs) hub and collocations
(COLOs) and cell sites.
For example, the Axxius 800 OCU-DP ports can be groomed and mapped into any of
the DS1 or DS3 ports of the Controller. The Axxius 800's (3/1/0) digital cross-connect
functionality offers DS0 service grooming, T1 drop-and-insert, and voice access
integration not available in traditional multiplexers.
The OCU-DP Service Cards have several local and remote management options
available through the Axxius 800 Controllers. Cards can be locally configured and
managed using the Command Line Interface (CLI). Remote management is
accomplished directly over either an in-band DS0 management channel or a separate
SNMP network connection, alternatively, remote management can be achieved
through the Access Navigator® over the Facility Data Link (FDL) or an in-band
dedicated DS0. Remote management will be further simplified using the graphical
configuration, and management and maintenance interfaces available in future releases
of the NetworkValet™ Enhanced Management System (EMS).
