| E1 Voice-Data Drop-Insert Multiplexer |
 Our
E1 Multiplexer the VCL-MX, 2Mbps E1 voice and data, drop-insert
(add-drop) multiplexer provides full range of voice (POTS)
and digital data services to subscribers located at different
locations, requiring to interconnect and establish a voice
and data network over an E1 link. The VCL-MX is available
in 4 versions, each providing different features and voice
/ data interfaces.
The Multiplexer may be used in Terminal or Drop-Insert configuration
to provide
- Toll Quality Voice services
- Interconnect LAN (Campus Network)
- Provide LAN-WAN Interconnectivity
- Provide Leased Lines on DSL for SOHO Applications
The VCL-MX E1 Interface operates at a primary rate of 2.048
MBits/Sec and provides a host of features including, channel
drop and insert facility over a network of VCL-MX, E1 Multiplexers,
for voice and data applications.
The VCL-MX has an effective, CLI (text) based "Network Management
System", which may be used for configuring the system, subsequent
remote monitoring and management of the inter-connected systems
in the network. Both Inband and Out-Of-Band configuration
and monitoring options are available. An extensive set of
alarms, for easy maintenance are provided in the system |

 STM-1
SDH Add-Drop Multiplexer |
 The
VCL100MC-1 STM-1 (up to 63 E1 / 84 T1) with E3, DS3, 8 port
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. 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.
VCL100MC-1 (up to 63 E1 / 84 T1) with E3, DS3, 8 port 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.
The system has two STM-1 optical / electrical interfaces in
the aggregate side and allows for up to 3 tributary add-on
cards. The following tributaries are available as add-on cards
for the chassis:
- 28 E1/T1 tributaries (software configurable as E1 or DS1)
- 1 E3/DS3 tributaries (software configurable as E3 or DS3)
- 8 port 10/100Base-T Ethernet (IEEE 802.3)
- 2xSTM-1o
- 2xSTM-1e/140Mbps tributary interfaces (software configurable)
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. |

| E1 PRI ISDN Q.931 Multiplexer |
 The
VCL-PRI (Primary Rate Interface) ISDN Multiplexer provides
an efficient and cost-effective platform to convert 30, dial-up,
analog voice circuits to a digital E1, PRI ISDN interface,
as per ITU-T Q.931 recommendations
Our E1 PRI ISDN Multiplexer offers a unique application to
deliver voice to campus, office and residential areas over
an IP backbone.
The VCL-PRI ISDN (Euro ISDN) Multiplexer may be used to connect
fully digital Corporate LANs and ISP Equipment and Networks
with E1, PRI ISDN interfaces to analog PSTN circuits, or analog
equipment.
The VCL-PRI ISDN (Euro ISDN) Multiplexer bridges the gap
between the analog and the digital E1 world by providing an
intelligent interface to connect E1, PRI ISDN to 30 analog
telephone sets. VCL-PRI ISDN (Euro ISDN ) Multiplexer is an
ideal choice for Corporate and ISP customers who wish to connect
their equipment with E1, PRI ISDN digital interfaces to analog
telephone sets.
The VCL-PRI ISDN (Euro ISDN ) Multiplexer shall interface
to the E1, PRI ISDN port of any Switch / Server / PBX using
PRI ISDN (Euro ISDN) signaling as per ITU-T Rec. Q.931 to
interconnect up to 30, analog interfaces to the E1, PRI ISDN
port.
Alternately, the VCL-PRI ISDN (Euro ISDN) Multiplexer can
be configured as a NT to connect to Cisco VoIP etc (TE) equipment
in order to provide 30 analog interface to it. |

| E3,
2/34Mbps PDH Multiplexer |
 The
E3, 2/34Mbps multiplexer is a third order skip multiplexer
/ demultiplexer unit, based on PDH (Plesiochronous Digital
Hierarchy) technology. It multiplexes 16, 2.048Mbps E1 tributaries
into a single 34.368Mbps E3 tributary. The multiplexer / demultiplexer
also does the reverse processing i.e. demultiplexing a received
34Mbps stream into 16, 2Mbps E1 tributaries.
CL-2/34 Mbps Multiplexer system consists of two VCL-2/34
Mbps terminals one each at the local and remote ends, connected
through a 34Mbps stream, providing end to end services for
sixteen, 2Mbps streams.
The VCL - 2/34 MBit/Sec. Digital PDH Multiplexer provides
16, 2Mbps E1 electrical interfaces which are multiplexed to
1, ITU-T compliant E3, 34MBits/Sec. G.703 electrical interface. |
