PT-60 3516 155M/622M 2.5G packet over SDH/MSTP/PDH optical router

Brief Introduction
PT-60  155M/622M 2.5G packet over SDH/MSTP/PDH optical router is a new generation intelligent MSTP, it offers a complete solution for traditional ADM services, broadband data service access, aggregation, transmission. 

PT-60 3516 is SDH STM-1/4/16 Add and Drop Multiplexer equipment , it has powerful functions, abundant interfaces, high service capacity, and flexible networking ability, it can flexibly distribute network bandwidth, it can be suitable for service aggregation center node in the transmission network.

PT-60 3516 155M/622M 2.5G packet over SDH/MSTP/PDH optical router can not only realize MSTP function, it also can be used as DXC equipment to realize 252 E1’s 64K cross connection function, it can be used as multi-direction PCM to realize E1 access and 64K service aggregation function.

The equipment is standard 19 inch 3.5U height. 


System Access Capability


Main Features


Multi-service aggregation

       PT-60 3516 supports different types of services access and aggregation, including STM-1, STM-4, STM-16, E1, FE, GE, 64K sub-service, etc.

      64K services include FXO, FXS, 4WEM, RS232, N*64K V.35, 64K co-directional G703 interface, ISDN (2B+D); 

      PT-60 3516 2.5G SDH/MSTP equipment over fiber optical equipment  can support 256 E1’s 64K cross connection;

High Integration

      PT-60 3516 MSTP master card integrates power supply, monitoring, cross connection and 2.5G optical interface, which saves the slot position to increase the equipment’s service capacity; 

Flexible networking

      PT-60 3516 MSTP can provide point-to-point, link net, ring network, T type network, multi-ring networking mode ,it can build up link, ring, star, tree, ring cutting , intersection ring, mesh network etc.

Complete Ethernet function

      Standard 10/100M Ethernet and 1000M Ethernet interface, adopting GFP encapsulation and VC virtual concatenation technology, line speed switching, adjustable bandwidth, rate adaptive. It can provide a complete Ethernet layer two switching function, supporting transparent transmission, exchange, aggregation. And it also supports VLAN, STP, LCAS, priority functions;

Perfect protection ability

      Optical network level protection: sub-net connection protection, multiplex section link protection (MSP 1+1), 2 fiber multiplex section shared protection ring (MSP2F RING);

Full hardware redundancy protection: 1+1 cross connection board protection, 1+1 power board protection; 1:6 TPS protection;

Modular function

      It can replace module to achieve smooth update from STM-1 to STM-4, it can be upgraded from STM1/4 to STM-16 by changing optical card. The expansion slot is all-purpose , it can insert or remove the expanded card to increase the service capacity or adjust the service access transmission type, so the system expansion is very convenient;

Unified NMS, convenient to upgrade and maintenance 

      PT-60 series products adopts the unified network management platform to do centralized operation, maintenance and management, realize the allocation and scheduling for circuits, ensure the safe operation of the network;

      PT-60 3516 equipment has the ability to do the remote software upgrading, which make it easy to do maintenance, and flexible to update new functions;

      DCC channel has the ability to transparently transmit NMS information of other manufacturers.

company show

Photel has the design ability in the equipment of SDH, PDH, PBX, IPPBX, PCM, TDMOIP, HDSL...

1, for the SDH, we had the tech of STM-1 to STM-64 in hand, so we can modify any function to follow the customer needed;

2, for PDH, the uplink optical rate can be 150M or 1.25G, the number of E1 can be 1-16, the ethernet can be FE and GE;

3, for PBX, our PBX can support the protocols of SS7, PRI, V5, R2, it can work as a central switch in the telecom network, it can translate different protocol each other, for eaxmple SS7 to PRI;

4, for IPPBX, we can have IPPBX function in our PBX, we only need to configure one or more IPS card in our PBX to have IPPBX function, IP phone can communicate with analogue phone by dialling;

5. for PCM, we have enough experience in PCM for any customer;

6, for TDMOIP, we have the tech of TDMOIP for 1 to 16 E1s, we have done this solution in FPGA to reduce the cost and easy in components buying;

7, for HDSL, our HDSL is in low cost design, and have good ferformance.
