SDH multiplexers | HX9500R-PTN

The HX9500R-PTN/SDH/SONET/PDH IMAP (Integrated Multi-Services Access Platform) is an economical integrated solution supporting PTN/SDH/ SONET/PDH simultaneously on the same platform.

It’s designed to support DS0 access and PDH interfaces over SDH/SONET or/and PTN (MPLS/CE). 

SDH/SONET capability includes either STM-1/4/16 or OC-3/12/48. Connectivity of an HX9500R-PTN is achieved non-blocking cross-connection between High Speed (HS) tributary modules (VCn/VTn fabric) and Low Speed (LS) tributary modules (DS0 fabric).

With the PTN10G interface card, HX9500R-PTN is then able to transport PDH/SDH/SONET over Packet Transport Network (PTN). With HX9500R-PTN serving as a gateway, existing TDM devices will be able to migrate from SDH/SONET/PDH to PTN smoothly and seamlessly.

With up to 4 STM-1/4/16 (OC-3/12/48) aggregate interfaces on cross-connect modules and 8 STM-1 (OC-3) or 2 STM-4 (OC-12) interfaces on tributaries, HX9500R-PTN offers service providers a versatile protection schemes including SNCP(UPSR) and MSP(1+1) protection for both ring and linear network topologies.

The non-blocking VC11/VC12/VC3/VC4 (VT1.5/VT2/ STS-1/STS-3) cross-connect capability of HS modules is up to 20 VC4. The HS tributary modules include optical STM-1/4 (OC-3/12), E3/T3, E1/T1 interfaces, FOM and Fast Ethernet/Gigabit Ethernet over STM-1/4/16 (OC-3/12/48). Ethernet signals are mapped onto STM payload through standard techniques such as GFP, LAPS, VCAT, LCAS, and non-LCAS. These HS (High Speed) modules are identical to those used in CXR-HX9400R-PTN.

Up to 21 E1 or 28 T1 bandwidth of DS0 can be mapped to HS interfaces via the VC-n/VT-n fabric. The non-blocking DS0 cross-connect capability on LS interfaces is up to 672 DS0 to act as a mini DACS. The modules include a variety of TDM, DTE, IP, and voice interfaces. All LS modules are identical to those used in CXR-QX3440.

All interfaces are fully compliant with the relevant ETSI standards and ITU recommendations. HX9500R-PTN provides full Operation, Administration, Maintenance and Provisioning (OAM&P) functionality. Users can easily operate HX9500R-PTN locally or remotely for centralized management with CXR-iNET (EMS) or CXR-iNMS (Integrated NMS) or other SNMP-based management.
