HSD on in highest-numbered H0 channel, or highest-numbered time-slots of a greater
channel; FAS and BAS are removed in the case of muItiple-H(j channels.
Reserved for other HSD rates.
Reserved for high-speed data occupying all capacity, other than in the I-channel, not
allocated under other commands: cannot be invoked when other HSD is on, or when var-
H-MLP is on (may also be impractical when video ¡s on, the latter then being confined to
the I-channel).
H-MLP switched off (this does not affect I-channel MLP).
H-MLP on at 62.4 kbit/s, occupying second 64 kbit/s channel except FAS and BAS
positions.
H-MLP on at 64/128/192/256/320 kbít/s in the lowest-numbered time-slots, (other than
TS3) of an HQ or greater channel.
H-MLP on at 384 kbit/s in time-slots 2-7 of a greater channel than HQ.
Reserved for MLP occupying all capacity, other than in the I-channel, not allocated under
other commands: cannot be invoked when other MLP is on, or when var-HSD ¡s on.
NOTE- When the "restrict" comrnand is in forcé the least significant bit of all octets covered by the HSD and H-MLP
arnands is set to " 1", so the effective data rale is less than that indícated by the command.

Can accept ISO-still picture baseline and spatial modes.
Can accept ISO-still picture baseline and progressive modes.
Can accept ISO-still picture baseline and amhmetic modes.
Can accepl s til I images encoded by the method defined in Annex D/H.261 (See Note)
NOTE - Admínistrations may use this optional procedure as a simple and inexpensive method
to transmit still images. However, Recommendation T.S 1 (JPEG) is preferred when the procedures
for usíng T.81 wíthin audiovisual systems are standardized.
Can handle graphics cursor data.
Can accept group 3 fax.
Can accept group 4 fax.
Can accept V.120 terminal adaptation within an LSD channel.
Can accepl V.120 terminal adaptation within an HSD channei.
