Product Description

Brief Introduction
PT**0T ***8 PCM equipment is 1U high, *9 inch width equipment. It has 4 slots for *4K interface and 1 slot for 4 port ETH card. *4K 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**4K type in one E1 electric interface, or can be transmitted as **0M rate 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 through optical transmission channel. The equipment has 2 SFP optical module slots, which can realize 1*1 mutual backups optical transmission channel. It has perfect NMS function, and its NMS protocol is compliant with photel’s NMS protocol.
