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.
E1_EURO_ISDN = 1,
T1_CAS = 2,
T1_RAW_CAS = 3,
T1_TRANSPARENT = 4,
E1_TRANSPARENT_31 = 5,
E1_TRANSPARENT_30 = 6,
E1_MFCR2 = 7,
E1_CAS_R2 = 8,
E1_RAW_CAS = 9,
T1_NI2_ISDN = 10,
T1_4ESS_ISDN = 11,
T1_5ESS_9_ISDN = 12,
T1_5ESS_10_ISDN = 13,
T1_DMS100_ISDN = 14,
J1_TRANSPARENT = 15
T1_NTT_ISDN = 16 /* Japan - Nippon Telegraph
E1_AUSTEL_ISDN = 17 /* Australian Telecom
T1_HKT_ISDN = 18 /* Hong Kong - HKT
E1_KOR_ISDN = 19 /* Korean operator
T1_HKT_ISDN = 20 /* Hong Kong - HKT over T1
E1_QSIG = 21 /*Basic call only
T1_QSIG = 23 /*Basic call only
T1_DMS100_Meridian = 35
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]
Same as the description for parameter ‘ProtocolType’ for a specific trunk ID (x = 0 to
7).
