Valid Range and Description
TP-260 only.
Must be set to 2.
1 = A-law (defaut)
3 = μ-Law
Usually A-Law is used for E1 spans and μ-Law for T1 and J1 spans.
Sets the PSTN protocol to be used for this trunk.

The gateway simultaneously supports different variants of CAS
and PRI protocols on different E1/T1 spans (no more than four
simultaneous PRI variants).
Same as the description for parameter 'ProtocolType' for a specific trunk ID
(x = 0 to 7).
Defines the trace level.
Valid options include:
0 = No trace (default)
1= Full ISDN trace
2 = Layer 3 ISDN trace
3 = Only ISDN Q.931 messages trace
4 = Layer 3 ISDN no duplication trace
Selects the framing method to be used for E1/T1 spans.
For E1
