PL1877A Microprocessor Radio Telephone Interconnect Parameter Modification
101 12/10
Direct Access/Selective Signaling Password
Parameter Function
45 Disable DTMF 1 tone upon automatic phone line access = 0
Enable DTMF 1 tone upon automatic phone line access = 1
Default = 0
Some automated equipment requires a specific indication that the patch is ready to
accept DTMF digits. When enabled, this parameter causes the patch to answer the line
with a DTMF 1 (instead of the usual beep).
50 Don’t require * access command from landline user on line 1 before allowing direct
channel access or selective signaling input = 0
Require * access command from landline user on line 1 before allowing direct channel
access or selective signaling input = 1
Default = 0
43 Don’t require * access command from land-line user on line 2 before allowing direct
channel access or selective signaling input = 0
Require * access command from landline user on line 2 before allowing direct channel
access or selective signaling input = 1
Default = 0
51 Don’t require * access command from attendant user before allowing direct channel
access or selective signaling input = 0
Require * access command from attendant user before allowing direct channel access or
selective signaling input = 1
Default = 0
133-138 Prefix to * land-line access command
Valid range = 0–$D. All unused digits must be programmed to $F.
To completely disable the prefix requires programming all digits to $F.
The landline user must enter this code as a prefix to the * command before being granted
direct channel access or selective signaling privileges.
139-144 Prefix to * attendant access command
Valid range = 0–$D. All unused digits must be programmed to $F.
To completely disable the prefix requires programming all digits to $F.
The attendant user must enter this code as a prefix to the * command before being
granted direct channel access or selective signaling privileges.
