ExternalDC-power architecture with reserve power
Candeo DC power system
The Candeo platform provides a simple, quick-to-deploy, and
easy-to-operate power solution. Based upon modular building blocks
(rectifiers, System Manager, DC distribution, and battery connection
modules), the system is designed to power -48 V DC applications. The
Large Candeo power system uses 50 A rectifiers and has a capacity of
1000 A; the Small Candeo (SP48300) uses 30 A rectifiers and has a
capacity of 300 A. Both Large and Small Candeo systems provide "plug
and walk-away" installation and setup. The platform can be reconfigured or
expanded while it remains online.
Signaling Server
CS 1000Msystems use a Signaling Server. The Signaling Server is an
PC-based server that provides a central processor to drive H.323 and
Session Initiation Protocol (SIP) signaling for IP Phones and IP Peer
Networking. It provides signaling interfaces to the IP network using
software components that operate on the VxWorksª real-time operating
system.
The legacy Nortel ISP1100 Signalling Server can still be used.
