Brief Introduction PT-50T 5256 photel telecoms transmission equipment adopts 9U(with fan) or 5U (without fan) high standard 19" rack. It supports multiple analog and data access, and fiber/electronic integration PT-50T 5256 photel telecoms transmission equipment with FXO/FXS equipment can connectwith other transmission equipment through its optical interface or standard E1interface. Telecom PCM MUX equipment can realize point to point communication and point tomulti-points communications by E1 or optical interface; and it can execute D/I(drop/inset) function through its own 240 E1 cross connection matrix; and it can have online test functions including remote channel circuit test and 2 wire subscriber line tests.
The maximum system capacity of 64Kbps interfaces are 240, and the maximum access capacity of E1 interface is also 240.
PCM Multiplexer equipment Supports different types of user services: 64Kbps co-directional and N×64Kbps synchronous data interface, 10/100M Ethernet interface, RS232 and RS485 asynchronous data interface, FXO, FXS, Hotline, Magneto, Carrier wave magneto interface and 2/4-wire E&M interface, etc
Powerful Net Management System
The NMS can set all operating parameters, it can measure receiving/transmitting level of the analogue interfaces and the accurate parameters of external lines, which can make it easy and convenient to do the maintenance;
The equipment can be set as D/I equipment, whichmakes it very flexible to drop or insert channels.
E1 interface, PDH optical interface,SDH optical interface, TDM over IP interface, HDSL interface and PON interface,etc.;
The cross connection matrix is 8192*8192;
2 NMS ports
ETH NMS port and RS232 port;
can be 220VAC or -48VDC or 220VAC +-48VDC.
The equipment can update the firmware and software remotely.
Technical Specification * ETH interface conforms to IEEE 802.3i related recommendations, supports 10/100M self-adaptive, half/full duplex self-adaptive; * E1 interface accords with ITU-T G.703 recommendations, the impedance is 75Ω and 120Ω, adopts IDC connector; * NMS information can be transmitted through free bytes in the transmission port, and the local equipment can be cascaded throughETH or RS232 NMS port; * Power consumption: less than 360W;
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!
