More details

360 ports FXO/FXS or E&M,4 ports Ethernet,4 ports E1 over fiber PCM Multiplexer:PCM-360


PCM-360 is a kind of point-to-point fiber transmission  Desktop multiplexer that developed based on special large scale integrated circuits.

It is with perfect alarm function and a phone convergence card.

It can use 12 piece of 30 channels phones business card simultaneously in the Machine frame.360 channels phones (optional),

1~4 E1 and  1~4 100M linear Ethernet ports (optional).

it Provide back up power which make sure complete working function, high integration, low consumption, stable performance and convenient usage
