SDH interface overview
Metropolis
®
AMU supports the synchronous transmission rates STM-1, STM-4, and
STM-16.
In the present release, STM-1, STM-4, and STM-16 optical as well as STM-1 electrical
interface types can be realized in a modular way by only changing the SFP. Four ports
on one main card are available to plug an SFP. However, only two of the four ports are
available for STM-16 transmission.
PDH interface overview
Metropolis
®
AMU 2m/4o and Metropolis
®
AMU 1m/1o provide PDH interfaces via an
option card.
The following PDH interfaces can be configured via an option card:
•
Sixteen 1.5 Mbit/s interfaces (only 2m/4o version with adapter card)
•
Two 34 Mbit/s interfaces (only 2m/4o version with adapter card)
•
Two 45 Mbit/s interfaces (only 2m/4o version with adapter card)
•
Sixty-three times 2 Mbit/s (120
Ω
and 75
Ω
version available)
•
Four times 2 Mbit/s (120
Ω
and 75
Ω
) at the EPL4_E14 option card
•
Thirty-two times 2 Mbit/s (75
Ω
) at the EPL4_E132_75 option card
•
Four times 2 Mbit/s at the ESW4_E14 option card. For the E1 interfaces, (120
Ω
and 75
Ω
) options available via the Lucent OMS.
Please note that legacy cards for 1.5 Mbit/s, 34 Mbit/s, and 45 Mbit/s require a
two-slot wide adapter card to fit in the shelf.
