Lease of digital data transmission connections

Along optical fibers there is a network made of SDH multiplexers. Using this system, PERN also leases digital channels.

This includes make a transparent line for data transmission between two defined points and ensuring its data rate within the range from   n x E1 (2 Mbit/s) through E3 (34 Mbit/s), STM-1 (155 Mbit/s) STM – 4 (622 Mbit/s) to 1 GbE (1.25 Gbit/s) in national and international relations.
