DT-7705 THE RIGHT SOLUTION DT-7705 router is specifically intended to meet traffic needs of emerging mobile radio access networks

(RAN). To support convergence within RAN the unit offers built-in functions for 2G, 3G and 4G servicestraffic processing. DT-7705 platform may be also used as a powerful wired traffic aggregating and routing

solution within operator and corporate networks, that is where multiplexing of large number of E1 lines isrequired. 2RU height 8-slot chassis featuring high degree of scalability and interfaces density supports up to 96

T1/E1 ASAP universal ports (any service, any port). Toward the trunk channel connection is available through Ethernet, FastEthernet (FW), Gigabit Ethernet (GE) and N x N1/E1 MLPPP interfaces. The unit additionally supports redundancy of controlmodule and network interfaces. Two of eight SAR-8 slots of DT-7705 are intended for installation of control modules, whilethe reminder 6 slots are intended for interface boards. Modular architecture of DT-7705 ensures flexible combining ofvarious interfaces and optimization of configurations depending on requirements to specific communication facilities.

Aggregation and Transportation of Services

To ensure maximum efficiency of traffic solution DT-7705transmits the services through the MPLS (Pseudo-wire

Emulation End-to-End=PWE3) based virtual channels. Theuse of such virtual channels allows to keep all the keyfeatures of the services, and at the same time enablesutilization of cost effective packet environment foraggregation thereof. To ensure maximum efficienttransportation solution DT-7705 router utilizes the cut-through transfer of the services through the MPLS (PWE3)based virtual channels. Application of virtual lines allowsimmunity of key features of the services and enablesutilization of cost effective packet environment foraggregation thereof. Encapsulation and transfer of TDMtraffic (such as 2G TDM services) in DT-7705 router isimplemented through the use of the draft-ietf-pwe3-cesopsn standard. The use of the circuit emulation service(CES) enables to minimize the load of the bandwidththrough the transmission of active time-slots only. DT-7705 also supports encapsulation of ATM traffic as per theRFC 4717 standard )also known as the draft-ietfpwe3-atm-ncap standard). The unit additionally supportstransmission of ATM services in the N:1 cell mode. Toenhance transmission speed ATM access ports arecombined using the IMA protocol. IMA protocol isterminated onto the DT-7705 unit, and only user data cellsbelonging to the VC/VP structure are being transferred.

Synchronization

To ensure correct transmission of data synchronous

interfaces of mobile traffic relay network are used in thenodes of respective mobile communication network.Network interfaces may be used by mobilecommunication network nodes as steady referencesources for distribution of radio frequencies andprovision of reliable handover of control between thenodes. DT-7705 version R1.0 supports external electronic,linear and adaptive timing, while the latter completelyensures cut-through synchronization. Important aspect ofDT-7705 architecture is hardware based support ofIEEE1588v2 standard, which defines the methods ofminimization of delay and delay variations effects (jitter).This is achieved by means of combination of thearchitecture particular features and power mechanismsof QoS provision to minimize timing traffic delays. Tosupport synchronization features control module isequipped with Stratum-3 class clock generator.

DT-7710 THE RIGHT SOLUTION

DT-7710 SR service router is designed for installation at small access points and central nodes ofdistribution networks. This unit enables service providers, cable networks operators and mobile

communications operators to expand the limits of transformation to the most remote boundaries of theirnetworks. At the same time the unit is an ideal solution for enterprises operating in key vertical markets,

including governmental agencies, municipal and transportation enterprises, financial and educationalinstitutions, which need to provide their end users with flexible, reliable and manageable services in connection withcommunication of voice, video and data. Featuring service reliability of operator class, DT-7710 router also offers theindustry widest set of functions, realized on a basis of modular and compact platform. The router is optimized for provisionof highly efficient services in connection with communication of voice, video and data, being available in two versions ofchassis: with 4 and 13 slots. Both models support wide range of interfaces and various data transmission speeds. DT-7710fully complies with requirements, which service providers, cable and mobile communication networks operators andcorporate customers may have with regard to perspective IP/MPLS platforms intended for delivery of innovative andprofitable services.
