4.4.2.
4 x STM-1 or 4 x 140/STM-1 switchable electrical/optical port
Connections are established through the connectors situated on the access modules and port card front
coverplate (Figure 29. on page 57).
The modules are inserted into the slot assigned to them and compliancy with the configuration of the port
card to connect.
The relationship is illustrated in Figure 28. on page 55.
