(**) = default value for parameter
Meaning cc pp qq ...
Enable the PES 
Model 103 option
02 1E **00 Normal trunk operation 
01 Model 103 enabled 
Note: Also requires correct trunk code, modem
chip, TRUNKS.CUS settings, and line type 01.
02 Ademco Fast DTMF alarm dialer is connected. 
04 UK alarm dialer 
FASTNet packet collection 
mode
02 28 00 = off (default) 
01 = on
Minimum number of feed 
digits required for DID feed
02 23 nn default is same number as number of feed digits in
oparam 09 - oparam 09 must be programmed first
Minimum overdial digits of 
subscriber Id for end-to-end 
or DID overdial access
02 22 nn minimum number of overdial digits - if this many
digits not heard the call will be rejected -
default is 1
Modem Protocol 02 1A **00 = Bell protocol 
01 = CCITT protocol 
NOTE: you must set this parameter before
setting baud rate.
Modem tones 02 0A **00 = answer tone pairs 
01 = originate tone pairs
No operation 01 00 None
No operation 01 04 None
Overdial DID 
(allow a DID number to 
accept overdials as if it were 
an end to end line)
07
06
18 aa dd nn nn nn nn
aa 00 = do not add adder into overdial 
01 = add adder in
dd   = maximum number of digits of overdial to
allow, maximum is 20 (14 HEX)(fewer with
timeout o.k.), when 8 or more digits are used
only the last 7 are used for subscriber ID lookup
nn nn nn nn = the DID number to treat as end to end - in
HEX, e.g. 261-0000 = 00 27 D3 50
The older form of parameter 18 still is allowed, with 
the adder not being added in to the overdial, as follows:
dd nn nn nn nn 
(For single trunk and pre-6E dual trunk) As above, but 
adder is used, and fewer digits are not allowed.
Overdial Timeout (for dual 
trunk only)
3
03 19 nn nn = timeout between overdial digits 
(**default = 13 88 = 5000 msec)
Serial/modem parity 02 0C **00 = even parity (7 bit) 
01 = odd parity (7 bit) 
02 = no parity (8 bit)
