                 PT-5064  pcm multiplexer 256 channel voice 




Brief Introduction

  PT-50T 5064 pcm multiplexer 256 channel voice over E1 or Fiber adopts 5U height standard 19" rack mountable chassis for exchange office. The powerful switching matrix provides 2048 x 2048 non-blocking cross connections. System supports maximum 48 x E1, and 416 x 64Kbps channels with the expansion chassis. Various network cards, such as PDH, E1 and TDMoIP (Ethernet) uplink card are available for fitting different networks requirement.

System designs with reliability enhancement, such as redundancy controller, 1+1 uplink and dual power supply. It can configure for point to point or point to multipoint networking with different type of transport media; and it can execute D/I (drop/inset) function by cross connection matrix as well.

PT-50T 5064 is managed by the powerful NMS system for real time monitoring, local / remote diagnostic and alarm control. System software can be downloaded remotely through the management control center without engineer on site.


Main Features


High density  The maximum access capacity of 64Kbps interfaces are 416, and the maximum access capacity of E1 interface is 64 as well.
Abundant Access Interfaces  PT-50T 5064 PCM equipment supports different types of user services: RS232 asynchronous data interface, FXO, FXS, etc.
Powerful Net Management System  It is convenient to set cross connection and the level of analog user interface, and read the devices’ settings by the NMS system.
D/I (drop/insert) function  PT-50T 5064 PCM Equipment can be configured to D/I equipment, it flexible to drop or insert channels. 
Many types of transmission card  There are many types of uplink cards. The card type will be: PDH card, E1 card, TDMOIP card, ETH card
High Reliability  PT-50T 5064 PCM Equipment supports redundant backup in power card, master card and uplink card. All types of cards support hot swap.
Remote Update function  The master card supports remote update function, the company will provide the update software, and the user can update the card for the remote equipment in its NMS center.
Unique ID card design  The ID card is fixed in the shelf; it can identify the equipment’s ID, and store the configuration data file and dynamic operating data. So if changing other functional cards will not influence NMS to identify the equipment, which makes it more stable during switching master control cards.

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!
