Hi there
I've been asked to provide a design for a SDH based network, consisting of 3 nodes: one cpe and 2 network nodes.
The network would look like this:
CPE --30km-- NODE-1 --15km-- NODE-2
The CPE must provide 1 STM-4, 2 STM-1 and 3 E3.
Node-1 must provide 2 STM-1 and 1 STM-4.
Node-2 must provide 2 STM-1, 1 STM-4 and 3 E3.
Between all units the speed would be STM-16.
For the CPE I've looked at the ONS 15305 with a 6-port E3, a 2-port STM-4 and a 2-port STM-1.
For both nodes I've looked at the ONS 15454E with STM-4, STM-1 and E3 circuits, but I'm not quite sure which interfaces to use as the STM-16.
Could anyone suggest what I'm missing and which modules to use.
Cheers, Lars
