TD-E1-30-FXO-FXS-MUX
Functions
TD‐E1‐30*FXS‐FXO‐MUX provides conversion between ITU‐T G.703 standard E1 and 1‐30 voice; realize the long‐distance extend of telephone line through E1 channel. T TD‐E1‐30*FXS‐FXO‐MUX is a high‐performance, multi‐type long‐range Ethernet bridge. Its small size, low cost and very appropriate to the cost‐sensitive bridging applications.
Product Characteristics
Realizes long‐distance monitoring of local device to the remote device based on self‐copyright IC; Provides two clock types: E1 master clock, E1 line clock;
1channel Ethernet for option
Can support reverse polarity and 16k ‐12k for option
Realize the automatically rate set of local device to remote device
Has the function of pseudo‐random code testing, convenient for opening of the circuit, and can be used as an error code instrument;
E1 supports 75Ω unbalanced and 120Ω balanced impedance at the same time; Provides 30 voice channels, support calling indication
Voice port supports O port and S port, O port connects switch and S port connects user’ phone;
