Introduction STM-1/4
SDH Multiplexer:
The
VCL100 STM-1/4 is a modular, and cost effective STM-1/4 SDH multiplexer equipment designed
to manage bandwidth and voice & data access services over STM networks. The products
are designed to support end-to-end provisioning and management of services across all
segments of the optical network. It combines innovative optical networking software with
the intelligence of SONET/SDH to deliver a flexible, cost-effective network solution.
The VCL100 STM-1/4 provides flexibility to the customers in terms of expansion to support
additional client interfaces by adding new modules in the field. It is also a scalable
system that enables the customer to start with an STM-1 network and upgrade to STM-4 as
the traffic demand increases.
The distinguishing features of VCL100 STM-1/4 over competing products are its
unprecedented port density, scalability, redundancy and upgrade-ability with its software
intelligence. The VCL100 STM-1/4 family of products can be managed through an integrated
NMS that manages all STM equipment, providing customers with end-to-end provisioning from
a single platform for multiple service types – from E1s, E3s, STM-1, STM-4, and
10/100Mbps Ethernet services.
The STM-1 / STM-4 can be managed through an integrated NMS
that manages all the equipment, providing customers with end-to-end provisioning from a
single platform for multiple service types - from E1/DS1s, E3/DS3s, E4/STM-1e, STM-1o and
10/100Mbps Ethernet services.
VCL100 STM-1/4 Network Element
Software
The VCL100 STM-1/4 node is managed
through the embedded NES (Network Element Software). The main capabilities of NES are
listed below:
- Switchover to redundant processor, power supply,
cross-connect and aggregate cards, in the event of any hardware fault.
- Auto Recovery after Input Power Failure in a redundant
system
- Node-wise Operations & Maintenance
- User programmable severity levels for Alarms
- Node-wise Alarming & Remote Login.
- Performance monitoring as per the standard specifications
(G.826).
- In-service monitoring of E1 tributaries.
