Tributary interfaces and ISDN interfaces
• STM-1 tributary interface at 155 Mbit/s according to G.957. The 155 Mbit/s optical
access is done with a universal connector type allowing SC, FC/PC, ST connector
types without external optical cable conversion 1643 AM only.
Note: The STM-1 aggregate interface of 1643 AMS according to G.957 utilizes
SFP’s with LC connector. SFP usage is only available for 1643 AMS STM-1
interface.
• STM-1 tributary interface at 155 Mbit/s according to the ITU G703-15. The
physical interface for the STM-1 signals is a coaxial female DIN 1.6/5.6 type
connector with an impedance of 75 Ω or a DIN 1.0/2.3 type connector if an SFP is
used.
• Interface at 1.544 Mbit/s ± 130 ppm, AMI or B8ZS encoded (programmable in
groups of 8) and conforming to G.703-2 standard 1991, asynchronously mapped via
VC-11 to a TU-12. The 1.5 Mbit/s electrical (DS1) interface access is via a RJ45
connector suitable for symmetrical twisted pair cables with an impedance of 100 Ω.
