VCL-STM-1
(upto 63 E1)
Network Element Software
Orion Telecom Networks Inc. offers 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 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 chassis:
- E1
- E3/DS3 tributaries
(software configurable as E3 or DS3)
- 10/100Base-T
Ethernet (IEEE 802.3)
- STM-1o
- STM-1e
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 Orion 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 Orion 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
