VCL-E3 Multiplexer |
|
| |
- VCL-E3, 34Mbps
Multiplexer is a third order skip multiplexer /
demultiplexer unit, based on PDH (Plesiochronous
Digital Hierarchy) technology. It multiplexes
sixteen 2.048Mbps (hereafter referred to as 2Mbps)
E1 tributaries into a single 34.368Mbps (hereafter
referred to as 34Mbps) E3 tributary. The multiplexer
/ demultiplexer also does the reverse processing
i.e. demultiplexing a received 34Mbps stream into
sixteen 2Mbps E1 tributaries.

VCL-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. Both
local and remote terminals can be monitored and
controlled by a Network Management System (NMS)
connected to the local terminal. The VCL-E3 can also
be used by itself to breakdown a E3 into (16) E1
channels.
- 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.
- Features

synchronizing on any of the 34368 kHz clock sources
- internal, external or extracted
- Remote and local
terminal monitoring and control by Network
Management System
- Optional TCP/IP Remote
Access for monitoring alarms and management
- Highlights
- Extensive alarms and
status indication facility
- Service bit monitoring
and insertion
- Operates on nominal
-48V DC input
- Distributed on-board
power supply
- Microprocessor
controlled with powerful diagnostic facilities for
both remote and local systems
- Local and remote
loopback facility for 34Mbps stream
- Stored program
controlled
- Highly reliable and
compact
- The system may be
deployed independently (with an industry standard
OLTE) or in conjunction with Valiant's Optical Line
Terminating Equipment (OLTE) in the following applications:
- To
provide inter-connectivity between two small
switches (central offices).
- To
provide connectivity between the Central Office and
the Remote Site in "Fiber In The Local
Loop" application.
- To
connect ISP's (Internet Service Providers) to the
"telco".
- To
provide an intermediate connecting link at
34MBits/Sec. in mixed PDH/SDH networks.
