RAD to Unveil Complete Gateway Solution for

Optimising Cellular and Enterprise NetworksNetwork Optimisation and Superior Voice Compression Technologies

Reduce Cost of Expensive Satellite and Microwave Links

RAD Data Communications will unveil at West and Central AfricaCom 2009, which will

be held in Abuja, Nigeria 17th-18thJune, a complete set of gateways that support 2G and3G cellular backhaul over landline, satellite and microwave radio links.

RADs Vmux-405, Vmux-425 and Vmux-445 GSM Abis optimisation gateways optimise

GSM Abis (BSC-to-BTS) traffic and transport it over an E1 or 10/100BaseT or GigabitEthernet link. Using these devices, cellular operators are able to lower their demand for

bandwidth and improve the utilisation of their access infrastructure, especially overexpensive satellite and microwave links. The Vmux-445 will also support Ater

optimisation.

RADs Vmux family also includes trunking solutions. The Vmux-2120, for example, is a

fully redundant 3G media gateway that provides compressed voice transmission overTDM and IP networks. It significantly reduces satellite bandwidth consumption and

lowers leased line costs for cellular operators, carriers and call centers. Employingpowerful voice compression algorithms as well as RADs patented TDMoIP

pseudowire technology, the Vmux-2120 3G media gateway can compress up to 16 fullE1 circuits over a single E1 line or IP uplink. The Vmux-2120 guarantees optimal

bandwidth utilisation while maintaining toll quality voice, lowering both operating(OpEx) and capital expenses (CapEx). At the same time, all legacy services and signaling

are maintained. It is a fully redundant unit and also features uplink redundancy, load

sharing and an echo canceller.

By optimising the Abis interface, the Vmux-405, Vmux-425 and Vmux-445 complete

RADs cellular offering by complementing our Vmux-2120 and Gmux-2000 voicetrunking gateways, which optimise and compress the E (MSC-to-PSTN) interface, notes

network capacity.

Clock Recovery over any Transmission Network

The Vmux-405 connects up to three E1 digital ports over a single E1 or up to four E1sover Ethernet, while the Vmux-425 connects up to six E1 digital ports over an E1 orEthernet and the Vmux-445 an impressive 63 E1s over E1/STM-1 or Gigabit Ethernet. A

single Vmux at the BSC side can operate with up to 20 remote units at the BTS over aTDM or Ethernet/IP/MPLS packet switched network (PSN) in a point-to-multipoint

application. Clock recovery over any transmission network enables the BTS tosynchronise timing with the BSC without a GPS, which is a critical advantage since

PSNs do not provide timing mechanisms of their own. A Smart Packet Drop (SPD)mechanism, moreover, enables additional optimisation of voice traffic by discarding non-

essential voice frames without any affect on voice quality.

All of RADs Vmux products conform to all relevant industry standards and interoperatewith equipment from major base station system vendors.
