Calling Channel Number
This number setting when initiating a call from the BS to the MS.
Valid Entry Range: 1 through 2023
NMT Frames Affected: 1a , 1a’, 1 a’’, 1 aS, 1a ’S, 1a’’S , 1b , 1bS, 2a, 2a’, 2a ’’, 2b , 2b’, 2 b’’,
2c, 2c’, 2c’’, 2d, 2d’, 2d’’, 2e, 2f, 10a, 10d, 11b.
Operating Considerations
This setting affects the RF frequencies the RF generator and analyzer tune to
when the TCHAN CC and RCHAN CC commands are used.
Each NMT standard has its own range of available channels.
Table 13 lists the
valid channel assignments for Calling, Traffic, and Access channels.
Calling Channel Power
This field specifies the calling channel’s power setting. Each Power setting
represents one of the four available levels allowed by the NMT standards.
Valid Entry Range: 0 through 3
NMT Frames Affected: 1a , 1a’, 1 a’’, 1 aS, 1a ’S, 1a’’S , 1b , 1bS, 2a, 2a’, 2a ’’, 2b , 2b’, 2 b’’,
2c, 2c’, 2c’’, 2d, 2d’, 2d’’, 2e, 2f, 10a, 10d, 11b.
Data Rate
This field specifies the rate that the frames are output in bits-per-second. This
field also sets the data rate expected by the NMT Decoder.
Valid Entry Range: 9.2 through 2400
