Introduction
Orion Telecom Networks Inc. offers 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.

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.
Operations Interfaces
10/100 Mbps half-duplex LAN
interface for NMS data connection to VCL100 STM-1/4 node (RJ45 connector)
RS232C Craft interface for local Command Line Interface data connection 2
wire analog telephone interface for Engineering Order Wire (E1 or E2 bytes
access) with omnibus calling In-band control channel supported for remote
management (F2 & F3 bytes used from POH).
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.
