GENERAL INFORMATION:Transfer 8 E1 signal through fiber
| product character: | | |
| (1)High integrate design, work stabile, very low failure rate. | | (2)E1 port use digital clock resume circuit and digital phase-lock circuit. | | 3) Voltage can select -48V/+24V/110V/220V, provide over-voltage and over-current protection, have high electromagnetism shield capability. | | (4) Jitter tolerance much better than GB. | | (5)Monitor remote equipment through fiber inter-band channel, display remote status on panel LED. | | (6)Provide function of 8 E1 remote loop, and 1 interface of phone. | | (7)Network manager interface use SNMP or RS485.(8)Two types:Standalone, desktop, 19inch;Card,usually be inserted in our rack 19 inch. |
