Parameter Description
'Trace Level'
configure voip >
interface e1-t1|bri >
trace-level
[TraceLevel]
Defines the trace level:
■ [0] No Trace (default)
■ [1] Full ISDN Trace
■ [2] Layer 3 ISDN Trace
■ [3] Only ISDN Q.931 Messages Trace
■ [4] Layer 3 ISDN No Duplication Trace
'Framing Method'
configure voip >
interface e1-t1 >
framing
[FramingMethod]
Determines the physical framing method for the trunk.
■ [0] Extended Super Frame = (Default) Depends on
protocol type:
✔ E1: E1 CRC4 MultiFrame Format extended G.706B
(same as c)
✔ T1: T1 Extended Super Frame with CRC6 (same as
D)
■ [1] Super Frame = T1 SuperFrame Format (as B).
■ [a] E1 FRAMING DDF = E1 DoubleFrame Format -
CRC4 is forced to off
■ [b] E1 FRAMING MFF CRC4 = E1 CRC4 MultiFrame
Format - CRC4 is always on
■ [c] E1 FRAMING MFF CRC4 EXT = E1 CRC4
MultiFrame Format extended G.706B - auto negotiation is
on. If the negotiation fails, it changes automatically to
CRC4 off (ddf)
■ [A] T1 FRAMING F4 = T1 4-Frame multiframe.
■ [B] T1 FRAMING F12 = T1 12-Frame multiframe (D4).
■ [C] T1 FRAMING ESF = T1 Extended SuperFrame
without CRC6
■ [D] T1 FRAMING ESF CRC6 = T1 Extended
SuperFrame with CRC6
■ [E] T1 FRAMING F72 = T1 72-Frame multiframe (SLC96)
■ [F] T1 FRAMING ESF CRC6 J2 = J1 Extended
SuperFrame with CRC6 (Japan)
Note:
■ If you are modifying the parameter for an existing
(configured) trunk through the Web interface, you must
first stop the trunk.
■ The parameter is not configurable for BRI interfaces; the
device automatically sets the BRI framing method. If the
TerminationSide parameter is set to USER_
TERMINATION_SIDE (0), ClockMaster is automatically
set to 0.; if the TerminationSide parameter is set to
NETWORK_TERMINATION_SIDE (1), ClockMaster is
automatically set to 1.
ISDN/BRI Configuration
'ISDN Termination Side' Determines the ISDN termination side.
