Typical applications





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.



if any requirements from your customers or yourself, please tell us any time, we will do our best for you!
