“IPVGate


20” and “PROTEI


mGate” for NGN solutions.


The differing principles of switching, control and transmission of information in existing
telecommunications networks prevent operators from exploiting their full potential. Special gateways are
empl
oyed to provide successful connection between traditional telephone networks and IP networks
(including Next Generation networks). Gateway equipment allows operators to expand their field of
activity and enables the deployment of new services. Designed and

manufactured by PROTEI Lab. mGate
called equipment line supports the exchange of voice traffic and signalling data between circuit
-
switched
and packet
-
switched networks. It converts various signalling protocols (E
-
SS1, SS7, CAS2, R2, SIP,
H.323, H.248/MEG
ACO, SIGTRAN) and provides interconnection between different kinds of networks.

IPVgate
-
20P is a cost

edge,
standalone ISDN device, which can serve as
VoIP Access Gateway or VoIP Trunking
Gateway, fully interop
erable with leading soft
switches and SIP servers.

Note: IPVgate
-
20P is part of the RAD VoIP
System (RVS)

roduct line.


The device employs superior voice technology
for connecting digital PBX systems to IP
-
based
telephony networks, as well as for integrati
ng
into new IP
-
based PBX architecture.

IPVgate
-
20P is a cost
-
effective, cutting
-
edge,
standalone ISDN device, which can serve as
VoIP Access Gateway or VoIP Trunking
Gateway, fully interoperable with leading soft
switches and SIP servers.


A call is routed

to the PSTN backup when

power failure occurs or if the IP network is

not functioning/responding. In addition, a
predefined table configuration guarantees

the routing of special subscribers through

the PSTN.

In order to ensure proper clock
synchronization,

IPVgate
-
20P can either
generate locally a TDM clock and provide it

to the PBX or synchronize to a clock received
directly from the PSTN and relay this clock to
the PBX.

IPVgate
-
20P can also be used as an E1/T1

PRI termination SIP media gateway.

VPN

Branch

offices can be easily and securely

connected to the HQ office using the built
-
in
VPN IPSec server/client. Utilizing a 3DES
encryption algorithm and up to 10 tunnels per
device, IPVgate
-
20P transparently connects the
enterprise LANs to a single virtual WAN
.

With the gathering pace of conversion to NG

networks, demand is growing fast for

hig

performance equipment that

can connect traditional telephone networks to

new, developing networks. The mGate line meets

and surpasses these requirements:

• Compatibility with third

party equipment.

In years of exploitation in the field, mG
ate

gateways have proven their complete

compatibility and reliability in use with equipment

from the world’s leading manufacturers. Regular

tests and trials maintain the mGate line’s high

AOC (Advice of Charge). AOC variations, such
as AOC metering, AOC currency, AOC at start
of call, AOC during call, and AOC at end of call
are also supplied.

An additional dual

purpose Sync/Backup

PRI interface allows cascading of units and

clock synchroniz
ation, which is essential

for qualitative PBX operation.




For applications that require SS7 signalling or
more than 1E1 trunk per gateway box, RAD is

FAILSAFE SUPPORT

IPVgate
-
20P performs SIP fail backup by

DNS number resolving.

When a central SIP server fails to respond,

IPVgate
-
20P accesses the operator or
Enterprise DNS server to resolve the IP

addres
s of the VoIP trunking gateway or of

another end
-
point device.

Utilizing its backup line (connected to

Telco lines) the unit can switch all phone

calls to regular telephony upon broadband

connectivity failure.

IPVgate
-
20P is equipped with an integrated

ADS
L modem and provides ADSL line

monitoring and re
-
routing of all traffic to a

backup router upon connectivity failure via

the additional Ethernet WAN interface.




• Wide range of supported codecs.
The ability

to work with different codecs means that mGate

equipment can be deployed in virtually any

network.

• Unified maintenance system.
System

maintenance can be carried out using a number

of means: Telnet/SSH, F
TP, a graphical Web

interface and command line interface. The system

for controlling equipment status and various

levels of alarm signal features an SNMP and can

be integrated with existing monitoring systems

already in the network. mGate modules are

conne
cted by a common management network,

allowing maintenance and reconfiguration to be

handled from one center.


• Adaptation.
mGate equipment features a

high
-
performance echo cancelling system

developed specially to deal with the peculiarities

of Russian tel
ecommunications networks.

• Traffic logging.
mGate provides CDR logging,

and can also log transit traffic.

• Network reliability.
To increase general

network reliability, all mGate equipment has

internal switching capability which is brought into

play if s
oftswitch servers are offline.

• Increased reliability.
The system has

safeguards to protect it from failures in the

control, switching, transmission channel and

power supply systems.

Equipment line


The mGate equipment line:

• mGate.ITG


a gateway fo
r conversion of

signalling protocols (E
-
DSS1, SS7, CAS2, R2, SIP,

H.323, H.248/MEGACO, SIGTRAN) and voice

streams. Scalable up to 16 E1.

• mGate.CTG


a gateway for creating

high
-
capacity connection points. The capacity and

number of E1 connections is spec
ified by the

operator and can easily be expanded if necessary.

In terms of its modular construction, mGate.CTG

is the same as mGate.ITG.

• mGate.CDR/ITG


dedicated equipment for

logging transit traffic from operators connected by

E1 streams. mGateCDR/ITG
keeps Call Detail

Records (CDR) for all calls. Aside from traffic

logging, mGate.ITG/CDR can also provide the

same functionality as mGate.ITG or mGate.CTG.



Application


mGate equipment can be used in a variety of

applications:

• As an IP
-
telephony gatew
ay for converting voice

and fax protocols transmitted over

circuit
-
switched networks into a format suitable

for transmission over IP networks.
