6.11 E1/T1 Configuration Parameters

Note: In Table 6-6, parameters in brackets are the format in the Embedded Web Server *.

Table 6-6: E1/T1/J1 Configuration Parameters (continues on pages 122 to 127)

ini File Field Name		Valid Range and Description
Web Parameter Name*
PCMLawSelect	1 = A-law
[PCM Law Select]	3 = ∝-Law
	Usually A-Law is used for E1 spans and ∝-Law for T1 and J1 spans.
FramingMethod	Selects the framing method to be used for E1/T1 spans.
[Framing Method]	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	Same as the description for parameter ‘FramingMethod’ for a specific trunk ID (x = 0
[Framing Method]	to 7).
ProtocolType	Sets the PSTN protocol to be used for this trunk.
[Protocol Type]	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	Same as the description for parameter ‘ProtocolType’ for a specific trunk ID (x = 0 to
[Protocol Type]	7).
