Centillion 1200N ATM Switch User Manual 2-1
NTP 297-8103-903
What is the Centillion 1200N Switch?The Centillion 1200N is a compact desktop 2.5 Gbps ATM Switch.
At the core is an input/output buffer switch that realizes a 2.5 Gbps nonblocking
throughput. The ATM Switch can accommodate up to four lines of 622 Mbps
interface conforming to the ATM Forum and ITU- T recommendations and up to 16
lines of 155 Mbps interface.
XATOM (eXpandable ATM Output Modular Switch), the core of the ATM Switch,
is equipped with a large-capacity buffer to ensure the sm ooth flow of mu ltimed ia
traffic and provide a powerful support to multimedia communications.
The ATM Switch supports both fixed path, or permanent virtual connections
(PVC), and variable path, or switched virtual connections (SVC), and features such
functions as ATM cell priority control, congestion control, and traffic monitoring.
In addition, by using the SNMP protocol, the ATM Switch can interface with a
network management system (NMS).
Features
The ATM Switch is a desktop ATM switch used for such applications as LAN-to-
LAN connection. The ATM Switch serves as the core of an ATM users' network.
The features of the ATM Switch are described below.
■Realizes 2.5 Gbps throughput
As the ATM Switch employs an output buffer type ATM switch with a
random access input-output buffer, it realizes high-capacity switching at a
high-speed total throughput of 2.5 Gbps of maximum switching capacity (at
155 Mbps × 16 lines maximum). Consequently, the ATM Switch can be used
to build a high-speed multimedia network.
■Has redundant configuration
Redundant configuration of power unit ensures high reliability.
