Add-Drop Multiplexer: STM-1, VCL100CPE ApplicationsThis configuration is used whenever
VCL100CPE is part of a ring or a linear chain. The box will be configured with two STM-1
optical interfaces (East and West) with E1 drop interfaces.
Add-Drop Multiplexer
STM-1 Terminal Multiplexer
In a terminal multiplexer configuration, only one STM-1 optical interface is used in an
unprotected set up. This is the case when VCL100CPE is either used as a spur or at the end
of a linear segment. If 1+1 MSP is also provisioned, an additional STM-1 optical interface
is required on VCL100CPE.

Network Applications
VCL100CPE is fully compatible with other members of the VCL100CPE family viz.,
VCL100CPE SDH Access Node (STM-I/4), VCL100 Cross-connect Node (STM-I/4) and VCL100
Multi-Service Provisioning Platform (STM-l/4). It can therefore be seamlessly used in an
end-to-end network configuration from the customer premises to the optical core.
The following figure shows a STM-4 network built using VCL100 Multi-Service
Provisioning Platforms with low drop requirements at a couple of locations. These
requirements can be cost-effectively addressed by using a VCL100.
Mixed Network Solution
With an increase in demand for Ethernet based data
services such as Internet access and Transparent LAN applications, VCL100 is the right
kind of product to meet such data requirements as shown in the following figure. This
shows a hubbed ring configuration, which is typical of an Internet Access application.
VCL100 MSPP, which supports an Ethernet Card, is positioned at the hub node and would
interface to the Gateway Router. VCL100, on the other hand provides data connectivity to
the end-user, at the customer premises.
Data Services
VCL100 on its own may also be used to build low-speed transport networks
as is shown below.
Low-Speed Backbone
This unique product supports end-to-end provisioning and management of
voice and data services across all the segments of the optical network - from the customer
premises to the core. It combines innovative optical networking software with the
intelligence of SDH to deliver a flexible solution to today's service providers. The
VCL100CPE can be configured as a Terminal Multiplexer (TMUX) or an Add-Drop Multiplexer
(ADM), with E1, E3, DS3 or 10/100 Ethernet Interface service
interfaces and trunk interfaces at STM-1 rate.
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.
