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.
User can access and control all
of the above-mentioned features using a standard HTTP based web
browser by enabling the Web server software module (NES-WEB-HTTP)
within the Network Element Software. The Ethernet interface on
the MIC (Management Interface Card) is to be used as the
physical data connection for this purpose. NES also allows users
to control remote nodes using SDH DCC bytes by enabling the
in-band communication module (NES-IBC).
To provide network
wide management and control of VCL100 STM-1/4 nodes through
industry standard Network Management Systems, users can enable
the Simple Network Management Protocol interface software module
(NES-SNMP). This module provides open interfaces which can be
also be used by Network Management System (NMS) which is
described later in this document.

Upgrades
VCL100 STM-1/4
supports hitless upgrade from STM-1 to STM-4 by replacing the
redundant STM-1 aggregate by STM-4 aggregate.
