Table 28: Trunk Card OPARAM Codes (continued)
(**) = default value for parameter
Meaning cc pp qq ...
Serial/modem speed 02 0B **00 = 300 baud Bell 103/CCITT V.21 
**01 = 1200 baud Bell 212/CCITT V.22
02 = 9600 baud
03 = 150 baud (for TNPP compatibility)
04 = 600 baud CCITT V.22-600
05 = 2400 baud (Multiport only)
06 = 4800 baud (Multiport only)
Note: You must set the baud rate BEFORE setting line 
type (parameter 09). Please note that CCITT vs. 
Bell is set by parameter 1A, and if used must be 
set before setting serial/modem speed. Note that 
parameters 03 and 04 are available only on the 
Dual Trunk at this time. Single trunk defaults to 
300 except for Line Type 11, which defaults to 
1200 for a serial port. A single trunk modem does 
not do 1200 baud. Dual trunk defaults to 1200.

03 06 nn nn = # milliseconds delay after supervision, see 
Table 30 on page 227
TCON

03 05 nn nn = # milliseconds that connect signal must be 
stable to recognize start of incoming call, see Table 30 
on page 227

03 07 nn nn = # milliseconds that disconnect signal must be 
present before dropping call For DID, loss of loop 
current, see Table 30 on page 227
Telco line parameters
1,2
05 09 byte 1 = line type, see following table.
2 = rings before answer (01 to 09 for end-end line
type only)
3 = number of feed digits (00 to 20)(14 HEX) 
when more than 8 digits are used, only the last
7 are used for subscriber ID lookup, note this 
does not apply to outbound trunks
4 = line permissions 
01 = in only
02 = out only
03 = two way trunk
Valid digit blocks 10 08 byte 1 = block number to program (00-09)
2 = block service code (for DID and E&M; see
Table 31 on page 227)
3 = not used
4-7 = prefix/adder for block
8-11 = low bound of valid digits
12-15 = high bound of valid digits
