Packet loss percentage at which the IP connection is considered a failure.
The range is 1% to 20%. The default value is 20%.
Transmission delay (in msec) at which the IP connection is considered a failure.
The range is 100 to 1000. The default value is 250 msec.
Valid Range and Description
1 = A-law
3 = µ-Law
Usually A-Law is used for E1 spans and µ-Law for T1 and J1 spans.
Selects the framing method to be used for E1/T1 spans.
For E1
0 = Multiframe with CRC4 (default, automatic mode, if CRC is identified in the Rx,
CRC is sent in Tx, otherwise no CRC).
a = Double frame
c = Multiframe with CRC4
For T1
0 or D = Extended super frame with CRC6 (default)
1 or B = Super frame D4, F12 (12-Frame multiframe)
A = F4 (4-Frame multiframe)
C = Extended super frame without CRC6
F = J1 - Japan (ESF with CRC6 and JT)
Same as "FramingMethod" for a specific Trunk ID (x = 0 to 7)
Sets the PSTN protocol to be used for this trunk.
