CL-S155TS MSAP STM-1 Standalone 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 4/8/16 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.
