IVD is able to support enterprise customer with high-speed service request. Customers can
subscribe multiple ADSL 2/+ lines by integrating security router with load balance feature. By
combining VoIP devices, system integrator provides multiple services with VoIP, Video on
Demand, and ADSL2/+ bundle solution. The IVD provide one-chip solution with ADSL, ADSL2
and ADSL2+backward compatible technology. The ADSL mode for ADSL/ADSL2/ADSL2+ is
configurable per subscriber ports. The system use ATM basic encapsulation method for data
transmission. ATM Layer is according to ITU-T Recommendation G.992.1, G.992.3, G.992.5 and
G.991.2. By the integrated POTS splitter and LT
function,
The IPDSLAM system is capable of
delivering high speed digital information over existing unshielded twisted copper pair telephone
lines without any changes. The ADSL transmission system is implemented according to ITU-T
Recommendation G.992.1 Annex A. The Frequency Division Duplexing (FDD) for FDM or EC
mode is used for separation of the upstream and downstream signals, as it is specified in ITU-T
Recommendation G.992.1, G.992.3 and G.992.5. To provide interoperability between ATU-C
(ADSL Transceiver Unit – Central) and ATU-R (ADSL Transceiver Unit – Remote), Handshake
Procedures for ADSL, ADSL2 and ADSL2+ Digital Subscriber Line transceivers is supported in
ADSL system according to ITU-T Recommendation G.994.1.
The rate of IVD when operating in, ADSL system supports downstream data rate from 32 kbps to
8 Mbps for ADSL mode, 32 kbps to 12 Mbps for ADSL2 mode, 32 kbps to 24 Mbps for ADSL2+
mode and upstream data rate from 32 kbps to 800 kbps for ADSL mode, 32 kbps to 1 Mbps for
ADSL2 mode, 32 kbps to 1 Mbps for ADSL2+ mode. Both downstream and upstream data rate is
adaptive and adjustable in 32 kbps increments.
The firewall and VPN security of VoIP security router is also provided by the architecture to meet
business requirements. This application is suitable on Telecom, Hotel and MTU applications. The
entire system is managed by EMS system.
Voice Features
The voice channel is 24 ports with Voice QoS guarantee. The feature of Signaling: Loop start
and polarity reversal can provide for billing purpose. The system provide external Ringing Source
and up to three REN. The Loop Current: 24 mA. The
Voice codec type should be G.711, G.729a, G.726, G.723.
