Specification

Features:

● Conforms to all relevant ITU series standards( ITU-T G.703 G.704 G.823),
● Transfer 1 E1 over fiber, framed and unframed E1 optional
● Capable to be communicated with V.35 fiber modem
● Both 75 Ohm and 120 Ohm in the same unit
● LED indicate local status and remote status, easy to understand easy to use
● Based on self -copyright IC.
● DIP switch management
● Provide 2 clock types: E1 internal clock, E1 external clock.
● Provide both local loopback and remote loopback.
● Support pseudo-random code test function, providing convenience for the test of optic fiber line status.
● E1 can support rate N*64k (N=1 to 32)
