PT-50T 1008 PCM Equipment



Brief Introduction

      PT-50T 1008 PCM equipment is 1U high, 19inch width equipment. It has 4 slots for 64K interface and 1 slot for 4port ETH card. 64K interface slot can insert different types of cards, such as FXS (8ch), FXO (8ch), 4W E&M (4ch) and hotline (8ch), etc. ETH card can be configured according to customer’s requirements, ETH can be transmitted as N*64K in one E1 interface, or can be transmitted as 100M in optical channel. There are 4 fixed E1 in the motherboard. Each E1 interface can be used as uplink interface to undertake voice service, etc. and it also can be used as the transparent transmission interface. The equipment has 2 SFP optical module slots, which can realize 1+1 optical transmission channel. It has perfect NMS function, and its NMS protocol is compliant with photel’s NMS protocol. 


Main Features


Can be configured as 32 voice/data channels, 4 E1 interfaces, 4ETH interfaces, with NMS function; 

Can be configured as 32 voice/data channels, 4 ETH interfaces, 4 uplink E1 interfaces, with NMS function;

Having 8 E1 cross connection matrix, it can be flexibly configured as D/I equipment;
