Web Parameter Name
Valid Range and Description
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).
TerminationSide
[ISDN Termination Side]
Selects the ISDN termination side. Applicable only to ISDN protocols.
0 = ISDN User Termination Side (TE) (default)
1 = ISDN Network Termination Side (NT)
Note: select ‘User Side’ when the PSTN or PBX side is configured as ‘Network
side’, and vice-versa. If you don’t know the gateway's ISDN termination side,
choose ‘User Side’ and refer to the ‘Status & Diagnostics>Channel Status’
screen. If the D-channel alarm is indicated, choose ‘Network Side’.
TerminationSide_x
[ISDN Termination Side]
Same as the description for parameter ‘TerminationSide’ for a specific trunk ID
(x = 0 to 7).
ClockMaster
[Clock Master]
Determines the Tx clock source of the E1/T1 line.
0 = Generate the clock according to the Rx of the E1/T1 line (default).
1 = Generate the clock according to the internal TDM bus.
For detailed information on configuring the gateway’s clock settings, refer to
Section
10.1 on page 243.
Note: The source of the internal TDM bus clock is determined by the parameter
TDMBusClockSource.
ClockMaster_x
[Clock Master]
Same as the description for parameter ‘ClockMaster’ for a specific trunk ID (x =
0 to 7).
TDMBusClockSource
[TDM Bus Clock Source]
1 = Generate clock from local source (default).
4 = Recover clock from PSTN line.
For detailed information on configuring the gateway’s clock settings, refer to
Section
10.1 on page 243.
TDMBusPSTNAutoClockEn
able
[TDM Bus PSTN Auto Clock]
0 = Recovers the clock from the E1/T1 line defined by the parameter
TDMBusLocalReference (default)
1 = Recovers the clock from any connected synchronized slave E1/T1 line. If
this trunk loses its synchronization, the gateway attempts to recover the clock
from the next trunk. Note that initially the gateway attempts to recover the clock
from the trunk defined by the parameter TDMBusLocalReference.
Note: This parameter is relevant only if ‘TDMBusClockSource = 4’
TDMBusLocalReference
[TDM Bus Local Reference]
0 to 7 (default = 0)
Physical Trunk ID from which the gateway recovers its clock. Applicable only if
‘TDMBusClockSource = 4’ and ‘TDMBusPSTNAutoClockEnable = 0’
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.
