Description:
Overview:
CL-S155T MSAP STM-1 SDH Transmission is adapt the kernel of SDH to transmit and collect the signal of PDH optical interface,STM-1 optical interface,E1 interface and so on with two standardlized STM-1 optical interfaces as the up connection. It supports 63 channels of E1 at most ; supports expanding Ethernet interface at rate of 100M; has ITU-T G.813 element location timing; VC-12 cross connection and channel protection function.It enables the connection with SDH transmission to be more seamless and managed; reduces the the DDF distribution frame and 2M lines; reduce the investment; reduce the fault rate; offers better access solutions for the operators to adapt.
Feature:
1. Have 21 E1 interfaces, enable to expand to 63 E1 interface at most and Ethernet interface with rate of 100M
2. Offer two STM-1 optical interfaces; enable to connect with various SDH devices; have 1+1 protection; can switch within 50ma; and enable recover to the normal status from the fault status.
3. adapt the kernel of SDH with SDH clock function.
4. adapt the plug-in design; enable to transmit E1, V.35 and Ethernet signal through the interface card; be the colloction of our exsited protocol converters and can connect with the existed devices.
5. have network management.
6. adapt the 4U rack, compatible with 220V and -48V, offer two powercards with heat backup function.
7. flexiable connection: point to point, single-directional channel protection with double fiber.
