Intelligent
E1 Channel Bank
Product
Description
Orion introduces new intelligent E1
Channel Bank E1 Channel Bank Multiplexer the VCL-CB with Voice Activity Detection (VAD) to provide voice activated
answer supervision and disconnect supervision to connect VoIP
(Voice over IP), |
|
| |
|
Voice over Frame Relay and Voice over ATM networks to analog PSTN
(POTS) lines that do not provide any type of answer supervision / battery reversal functions. |
The interface to the analog PSTN (POTS*) lines have been ruggedized to
provide complete protection against line card failures which occur from induced voltages
from AC power lines and lightening strikes and difficult field conditions.
Intelligent E1 channel bank is especially designed for the VoIP (Voice over
IP), Voice over Frame Relay and Voice over ATM network call-termination and long distance
communications market that will terminate calls directly to the analog PSTN lines. The
channel bank solution provides a cost-effective platform to convert upto 30 dial-up,
analog (PSTN) voice circuits to a digital E1 interface to connect to VoIP (Voice over IP),
Voice over Frame Relay and Voice over ATM Gateways.
Orion's years of experience in providing telecom transmission solutions to
customers worldwide, located in over 30 countries, has been
build in to providing a cost-effective - yet an intelligent E1 channel bank solution.
- For long distance traffic termination on PSTN lines that "Support",
or "Do Not Support" "Battery Reversal / Polarity Reversal"
(Answer Supervision).
- Voice Activity Detection (VAD) to provide
spoof “Answer Supervision”
- To provide “Disconnect Supervision” to disconnect
hung PSTN lines.
- Provides complete line protection against difficult field
conditions.
- Also used in conventional applications to deliver voice over
an end-to-end E1 (radio / fiber / HDSL) links.
The VCL-CB, E1 Channel bank offers all types of analog
interfaces including FXO, FXS and 2W/4W E&M interfaces, that may be required to
connect to an E1 digital interface of a VoIP (Voice over IP), Voice over Frame Relay and
Voice over ATM Gateway.
The E1 Channel Bank shall interface to the E1 port of any VoIP Gateway / Switch / Server /
PBX using R2 CAS (R2 Digital) Signaling (R2 Channel Associated Signaling) as per ITU-T
Q.421 / Q.422 recommendations, to connect up to 30 analog interfaces to an E1 port.
The VCL-CB intelligent Channel Bank is especially useful for
providing an analog interface to the latest servers from the following companies:
- Cisco AS2600 Voice over IP servers
- Cisco AS3600 Voice over IP servers
- Cisco AS5300 Voice over IP servers
- Cisco AS7200 Voice over IP servers
|
- Nuera 200 Voice over IP servers
- Mockingbird Voice over IP Servers
- Lucent ITS-SP, Voice over IP server
- Lucent PortMaster 3

Please consult factory for the complete list of compatible
CISCO ASXXXX VoIP Servers.
VCL-CB-INT™ E1, Channel Bank
Remote Access Server / VoIP Gateway Application
The cable plant of most telecom service providers is not
designed to deliver E1 services to customers in most parts of the world. The VoIP Gateway
/ Switch / Server / PBX with an E1 interface, thus, in such cases can only be accessed
through dial-up, 2 wire analog lines, the only available link for connecting the Exchange
(Central Office) to the Corporate PBX Networks and VoIP (Voice over IP) Gateways.
VCL-CB, intelligent E1 Channel Bank is especially useful in countries, where the cable
plant is not equipped to deliver digital E1 services to the customer, who are using the
next generation access equipment, which can only connect to an E1 interface.
The E1 Channel Bank solution is
available in two versions:
- The first E1 channel bank
(VCL-CB-BR™) provides answer supervision when the called party answers, upon
receiving an actual battery reversal of the PSTN analog line.
Both, the line connect and disconnect functions
are provided using the actual battery reversal function of the
PSTN analog line (e.g. much like your coin pay-phones).
Available with FXO, FXS and E&M
interfaces. |
- The second E1 Channel Bank (VCL-CB-INT) is an intelligent E1
Channel Bank that provides the metering function using Voice Activity Detection (VAD) to
provide voice activated "answer supervision" and "disconnect
supervision". The VCL-CB-INT, intelligent E1 Channel Bank uses a sophisticated DSP
algorithm to "listen" to the PSTN line for "voice activity" and will
provide "answer supervision" information to initiate the metering process when
the CALLED PARTY answers. It will also "listens" to the line to determine the
end of a call (silence) to provide line the "disconnect supervision".
|
The VCL-CB-INT™ E1 Channel Bank is
available with FXO interfaces which shall connect to the analog PSTN (POTS*) lines from
the local Exchange / Telco / Switch.
* POTS: Plain Old Telephone Service
