Valid Range and Description
PCMLawSelect
[PCM Law Select]
1 = A-law
3 =
µ-Law
Usually A-Law is used for E1 spans and
µ-Law for T1 and J1 spans.
FramingMethod
[Framing Method
]
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)
FramingMethod_x
[Framing Method]
Same as the description for parameter ‘FramingMethod’ for a specific trunk ID (x = 0
to 7).
ProtocolType
[Protocol Type]
Sets the PSTN protocol to be used for this trunk.

Note:
The Mediant 2000 simultaneously supports different variants of CAS and PRI
protocols on different E1/T1 spans (no more than four simultaneous PRI variants).
ProtocolType_x
[Protocol Type]

7).
