Siemens S30810-Q2160-X100 STMA

The STMA has an optical fiber interface with a transmission capability of up to 155 Mbit/s. Since it serves up to 4 2Mbit highways on the system side, only 8 Mbit/s are used. The STMA can be connected to an ATM switch or directly linked with another STMA via an optical waveguide (OWG). The fiber optic interface offers 4 (logical) ports in both operating modes (PBB and IW).

The STMA board offers two features in Hicom 300E V1.0:

2. Networking of Hicom 300 systems via ATM networks (PBB = PBX "Backboning")
3. Interworking (IW) between narrowband users of a Hicom 300 and wideband (broadband) users of an ATM workstation as well as interworking between 2 Hicom systems.

Features of the ATM interface:

• Serial 155 MBit/s interface

• Transfer rate with SDH/SONET control: 155.52 Mbit/s (+- 20 ppm)

• Transfer rate without SDH/SONET-control: 149.76 Mbit/s

• Range up to about 25 km (15.5 miles)

• Framing: SONET or SDH (STS3c or STM-1), administrable
