Terrestrial time slots:
T1 = 1 to 24
E1 (CCS) = 1 to 31
E1 (CAS) = 1 to 15 and 17 to 31
Channels: 1 to N (N = Satellite Data Rate ÷ 64 kbps)
N = 30 (1920.0 kbps) is a transparent mode which
disables time slot to channel mapping.
On entry, drop channel 1 and the current time slot are displayed. Press [↑] or [↓] to
