Network Element Software: STM-1 (optical / electrical) with upto 63 E1s with
E3, DS3, 10/100BaseT Ethernet interfaces


The VCL100MC-1 STM-1 (upto 63 E1) with E3, DS3, 10/100BaseT Ethernet interfaces is a compact, modular, and cost effective STM-1 SDH multiplexer equipment designed to manage bandwidth and provide E1 or fractional E1, voice and data access service over STM Networks. The STM-1 offers both electrical STM-1 (1+1) and optical STM-1 (1+1) interfaces. It is customized for the traffic demands, in the access network, typical of residential or business customers. The product supports end-to-end provisioning and management of services across all the 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.

Data Sheet (PDF)

VCL100MC-1 (upto 63 E1) with E3, DS3, 10/100BaseT Ethernet interfaces is a 3U height multi-card chassis system that provides flexibility to the customers in terms of expansion to support additional client interfaces by adding new modules in the field.

STM-1 VCL100MC-1 - upto 63 E1 / 84 T1 with E3, DS3, 8 port 10/100BaseT Ethernet interfaces

The system has two STM-1 optical / electrical interfaces in the aggregate side and allows for upto 3 tributary add-on cards. The following tributaries are available as add-on cards for the chasis:

  • E1
  • E3/DS3 tributaries (software configurable as E3 or DS3)
  • 10/100Base-T Ethernet (IEEE 802.3)
  • STM-1o
  • STM-1e/140Mbps tributary interfaces (software configurable).

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.

Additionally it provides a single 10/100Base-T Ethernet port, which can be mapped to one VC-12 bandwidth towards the aggregate side. This feature does not use any tributary slot and hence can supplement E1/DS1/E3/DS3 customers requiring a single Ethernet interface. This Ethernet interface on the base card is optional.

VCL100MC-1 Network Element Software (NES)

The VCL100MC-1 node is managed through the embedded (Network Element Software). The main capabilities are listed below:

  • Switch over to redundant power supply 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.

A standard Network Element Software (NES) starter package enables all of the above.

User can access and control all of the above-mentioned features using a standard Hyper Text Transfer Protocol (HTTP) based web browser. The Ethernet interface on the base chassis is to be used as the physical data connection for this purpose. The NES also allows users to control remote nodes using the web browser interface. For this purpose Valiant uses SDH DCC bytes for carrying the management information to the remote node.

To provide network wide management and control of VCL100MC-1 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.

The (NES) point-and-click provisioning tool (PNCP) is a set of software modules that enables customers to provision end-end circuits is a network that comprises all Valiant family of SDH products. Users can enable this feature using the node-resident software module NES-NODE-PNCP, and the server-resident software module NES-HOST-PNCP.

Network Management System

The STM-1 / STM-4 provides support for centralized network management through Network Management System (NMS).

Operations Interfaces

  • 10/100 Mbps half-duplex LAN interface for NMS data connection to VCL100MC-1 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
