Valid Range and Description
ProtocolType
[Protocol Type]
Sets the PSTN protocol to be used for this trunk.
1 = E1_EURO_ISDN
2 = T1_CAS
3 = T1_RAW_CAS
4 = T1_TRANSPARENT
5 = E1_TRANSPARENT_31
6 = E1_TRANSPARENT_30
7 = E1_MFCR2
8 = E1_CAS_R2
9 = E1_RAW_CAS
10 = T1_NI2_ISDN
11 = T1_4ESS_ISDN
12 = T1_5ESS_9_ISDN
13 = T1_5ESS_10_ISDN
14 = T1_DMS100_ISDN
15 = J1_TRANSPARENT
16 = T1_NTT_ISDN (Japan - Nippon Telegraph)
17 = E1_AUSTEL_ISDN (Australian Telecom)
18 = T1_HKT_ISDN (Hong Kong – HKT)
19 = E1_KOR_ISDN (Korean operator)
20 = T1_HKT_ISDN (Hong Kong - HKT over T1)
21 = E1_QSIG
23 = T1_QSIG
31 = E1_FRENCH_VN3_ISDN
35 = T1_DMS100_Meridian
40 = E1_NI2_ISDN
Note: The gateway simultaneously supports different variants of CAS and PRI
protocols on different E1/T1 spans (no more than four simultaneous PRI
variants).
ClockMaster
[Clock Master]
Determines the Tx clock source of the E1/T1 line.
0 = Recover clock from the E1/T1 line (default)
1 = The clock is generated by the gateway
For detailed information on configuring the gateway’s clock settings, refer to
Section
10.1 on page 293.
Note: The source of the internal TDM bus clock is determined by the parameter
TDMBusClockSource.
AutoClockTrunkPriority
[Auto Clock Trunk Priority]
Defines the trunk priority for auto-clock fallback (per trunk parameter).
0 to 99 = priority (0 is the highest = default).
100 = the SW never performs a fallback to that trunk (usually used to mark un-
trusted source of clock).
Note: Fallback is enabled when the TDMBusPSTNAutoClockEnable parameter
is set to 1.
LineCode
[Line Code]
0 = use B8ZS line code (for T1 trunks only) default.
1 = use AMI line code.
2 = use HDB3 line code (for E1 trunks only).
Use to select B8ZS or AMI for T1 spans, and HDB3 or AMI for E1 spans.
LineBuildOut.Loss
[Line Build Out Loss]
Selects the line build out loss to be used for T1 trunks.
0 = 0 dB (default)
1 = -7.5 dB
2 = -15 dB
3 = -22.5 dB
Note: Not applicable for E1 trunks.
