PSME provides connection and processing up to 48 grouped flows with transfer rate up to 2048 kbps or 12 grouped flows with transfer rate 8448 kbps each according to ITU-T G.703 n ITU-T G.704 international recommendations in AMI codes (only for 2048 kbps) or HDB 3.
PSME implements the concept of electronic cross for digital streams E1/ E2 with discrete switching one channel - 64 kbit/s. Number of group flows - up to 48 E1 or 14 E2 in different combinations. Remote monitoring, switching and diagnostics is possible with control program.
