(b) UTU-701C and ETU-751C have 32 time slots (TSs) available for HDSL payload
rates of 256 kbps to 2048 kbps.
(c) When communicating with another RS G.703 unit, the actual HDSL payload rate is
as follows:
• If set to 64 or 128 kbps (1 or 2 TSs), the actual HDSL payload rate is 256 kbps.
• If set to less than 1984 kbps (31 TSs), the rate is the indicated rate plus 128 kbps.
• If set to 1984 kbps (31 TSs), the actual rate is 2048 kbps. See "HDSL Payload
Rates" on
page
(d) When RS G.703 units communicate with RS V.35 units, the HDSL payload rates are
as described in the RS V.35 documentation.
(e) Data transmission switches to unstructured mode when set for 32 TSs (2048 kbps).
(f) Indicated payload rates are displayed in the Config LTU and Config NTU Interface menus
as Data Rate/# of TSs (data rate/number of time slots).
