VCL-STM-1,
VCL100LT (upto 28 E1)
Applications
Orion Telecom Networks Inc. offers 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
The chassis is 19" rack or wall
mountable as per customer requirements.
STM-1 Add-Drop Multiplexer:
STM-1, VCL100CPE
Applications
This 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.
