The STMA (Subscriber and trunk modules for ATM (asynchronous transfer mode)) board offers two features in Hicom 300E V1.0:
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).
Characteristics of the optical ATM interface are:
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 of about 2 km (1.24 miles)
Frame: SONET or SDH (STS3c or STM-1), administrable
