Maximum wait time for post message
signal
0: 12 s
1: 30 s
1: Maximum wait time for
post message
(EOP/EOM/MPS) can be
changed to 30 s.
Change this bit to “1” if
communication errors occur
frequently during V.17
reception.
NOTES:
1. If a setting is unnecessary, store FF in the address.
2. Pulse dial parameters (addresses 48094A to 48094F) are the values for 10
pps. If 20 pps is used, the machine automatically compensates.
3. The first ring may remain undetected until 1 to 2.5 wavelengths after the time
specified by this parameter.
4. The calculated level must be between 0 and 10.
The attenuation levels calculated from RAM data are:
High frequency tone: - 0.5 x N401F52/401F54 -3.5 dBm (PSTN)
- 0.5 x N
401F55 dBm (ISDN)
Low frequency tone: - 0.5 x (N
401F52/401F54 + N401F53) –3.5 dBm (PSTN)
- 0.5 x (N
401F55 + N401F53) dBm (ISDN)
Note: N
480952, for example, means the value stored in address 480952(H)
5. The actual inter-digit pause (pulse dial mode) is the sum of the periods
specified by the RAM addresses 401F4A, 401F4D, and 401F4E.
