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. Flexible connection: Point to point, single-directional channel protection with double fiber.
