Summary

This annex describes those specifications that are unique to Synchronized Symmetrical Digital Subscriber Line (SSDLS) transceivers for use in the same cable binder as TCM-ISDN defined in ITU‑T G.961 Appendix III. The SSDSL transmission method allows symmetric  data rates in the range of 192 kbit/s to 1.6 Mbit/s with 32 kbit/s granularity using a scheme synchronized with TCM‑ISDN.
