The power/LCT LTU provides connection to the DC power supply via a single 3-pin-D type connector.

An RJ45 port provides local access to the equipment via a PC.

Two power/LCT LTU can be fitted in slots 3_20 and Slots 3_21 for protection of the DC power supply.

Only the power/LCT LTU at slots 3_21 provides LCT access for the equipment.

Increased flexibility – interfaces plug into sockets on Core cards, Quad flexible Tributary cards and Ethernet Tributary cards

Rugged solution for simple and reliable installation

Reduced installation time

Standardisation on LC connectors

Increased flexibility, same SFPs used in other Marconi Next Generation products, OMS16-XX and PacketSpan - reduced inventory cost

In-service upgrade without removing card in the appropriate core, simply plug in module

In-service upgrade STM-1 to STM-4 in SMA1/4UC and SMA1/4EX, STM-4 to STM-16 in SMA16UC and SMA16EX

SFPs, hot pluggable - convenient, easy-fit, consumer-type, latching module clips into on-card socket
