SDH interface overview

1643 AM supports the synchronous transmission rates 155 Mbit/s (STM-1) and 622

Mbit/s (STM-4).

1643 AMS supports 155 Mbit/s (STM-1). All optical interface units support SDH

formatted signals.

The following synchronous interfaces are available in the present release:

• One or two STM-1 or two STM-4 optical line interfaces for 1643 AM

• One or two optical STM-1 line interfaces with SFP (Small Form Factor Pluggable)

for 1643 AMS. With the SFP several optical interface types can be realized in a

modular way by only changing the SFP

• Two STM-1 tributary ports (optical or electrical) configurable via an option card

(1643 AM only with STM-4 main motherboard, no SFP usage)

• STM-1 electrical SFP and SFP for single fiber working with 1643 AMS

PDH interface overview

1643 AM / 1643 AMS provide the following integrated PDH interfaces:

• Up to sixteen 2 Mbit/s (E1) interface ports, configurable as G.703, G.704, and

G.706 interfaces (75 Ω or 120 Ω)

• Up to sixteen 1.5 Mbit/s (DS1) interface ports (100Ω) in the 1643 AMS DS1

version

The following PDH interfaces can be configured via an option card:

• Sixteen 1.5 Mbit/s interfaces

• Sixteen 2 Mbit/s interfaces

• Two 34 Mbit/s interfaces

• Two 45 Mbit/s interfaces
