Product Overview
Basics
The Nimbra series of multi-service switches runs the DTM (Dynamic
synchronous Transfer Mode) network protocol, standardized by ETSI, which is
designed to increase the utilization of optical fibers and minimize the load of
the network nodes. The protocol is also designed to support real-time
broadband traffic, multicasting, and the ability to dynamically adapt to traffic
variations in the network.
DTM combines the simple, non-blocking, real-time traffic capabilities of circuit
switching with the dynamic resource handling of packet switching technology.
This covers a gap in available techniques on the market and meets the demands
of strict quality of service requirements for high-bandwidth communications.
About the Nimbra One
Nimbra One is a modular switch with hot-swap support for one control module
and up to seven interface modules. The backplane provides up to 20 Gbps
switching capacity, with an average non-blocking capacity of 5 Gbps, making it
ideal for all cases of multi service access switching. A Nimbra One can be
equipped with: One Control Module (mandatory in slot 1) and any combination
of trunk and access modules, presented below:
Trunk modules:
4 x DS3/E3 Trunk Module
OC-3/STM-1 Trunk Module (DTM150 Trunk Module)
4 x OC-3/STM-1 Trunk Module
OC-12/ STM-4 Trunk Module (DTM 622 Trunk Module)
2 x OC-12/ STM-4 Trunk Module
1 Gbps Optical Trunk (DTM1000 Trunk Module)
OC-48/ STM-16 X-ADM Module
Access modules:
Fast Ethernet Access Module
Gigabit Ethernet Access Module
T1 and E1 Access Modules
SDI Video Access Module
ASI Transport Access Module
