Ericsson has 3 type of possible HLS: *2 Mbps ITU-T ATM HSL link *2 Mbps ITU-T HDLC HSL link *1.5 Mbps ANSI/ATM HSL Thanks 14th July 2015 at 16:10 #69561 Wallis DudhnathGuest Depends on the Market. As an example for Europe 2Mbits/s HSSL will be used. HSSL basically contains ATM Cell frames. For configuration MML commands will be used for the HSSL routes.
