 Network Element Software: STM-1
with 14 E1) with any one interface card (E3 / DS3 / 8 port
10/100BaseT Ethernet):
The  STM-1, VCL100CPE (with 14 E1) and with one tributary interface card (E3 / DS3 / Ethernet) is an ultra-compact
and cost-effective customer premises bandwidth provisioning STM-1 SDH multiplexer
equipment designed to meet low or medium capacity bandwidth service demands.
Following tributary choices are available:
- E1s (standard part of equipment / chassis) with
- (any one of the following) E3 or DS3 or 10/100 BaseT Ethernet

VCL100CPE
Network Element SoftwareThe VCL100CPE node is managed through the embedded NES (Network
Element Software). The main capabilities of NES are listed below:
- Switchover 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 El tributaries.
A standard NES Software
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. NES also allows users to control remote nodes using the web
browser interface. For this purpose we use SDH DCC bytes for carrying the management
information to the remote node.
To provide network wide management and control of
VCL100LT 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 separately.
Operations Interfaces10/100 Mbps half-duplex LAN interface for NMS data
connection to VCL100LT node (RJ45 connector)
RS232C Craft interface for local Command Line Interface data connection
2 wire analog telephone interface for Engineering Order Wire (E l or E2 bytes access)
with omnibus calling
In-band control channel supported for remote management (F2 & F3 bytes used from
POH)
